Android - Device Memory Leak with Fragments

Android - Device Memory Leak with Fragments - android

Spent 3 days on this issue and I'm stumped, could reallly use your help on this.
My app uses a single activity that contains a fragment manager. In its current state, I've designed it to only have a single fragment attached at any one time. I call:
getSupportFragmentManager().beginTransaction().replace(R.id.main_fragment, mCurrent).commit();
to remove the existing fragment and replace it with the new one. The fragments are not being stored anywhere else. (Just mCurrent and the transaction manager which get replaced when the next fragment is opened)
The issue that occurs is not an OutOfMemory exception, but instead the entire app restarts because the device itself runs out of memory. The logs says nothing except stuff like DeadObjectException and:
9-17 11:34:14.742: W/InputDispatcher(341): channel ~ Consumer closed input channel or an error occurred. events=0x9
09-17 11:34:14.742: E/InputDispatcher(341): channel ~ Channel is unrecoverably broken and will be disposed!
These are coming from the device logs and not my app logs. And they don't provide enough information for me to trace what is causing them. The memory from the app is never released and the tablet becomes unusable from that point.
I've used all the tools I know available to analyze what the memory leak would be but nothing stands out. I used MAT (MemoryAnalyzerTool) and the Eclipse DDMS tools to figure out what may be going wrong. MAT reports between 8MB-16MB of total memory in use after I visit many different fragments. I look at the Leaks Report and nothing seems out of the ordinary. About 3MB for Imageviews, 3 MB for Bitmaps, and 8MB for other. In DDMS, the heap says I'm using ~50% of the app's allotted size. When I look at the Settings at the running processes, each Fragment I visit makes the memory amount from my app fluctuate between 30-140MB however the device itself never decreases in memory, hence why the device runs out of memory. Even when the app is completely closed, exited, destroyed, the memory is never released. All 759MB are used even though the sum of all the current running apps is about 200-300MB.
My assumption is that it is either holding on to the fragment itself in memory, or something contained within these fragments even though my app isn't. I call GC after each fragment swap.
I'm using the Samsung Galaxy Tab 2 10.1", but the same issue occurs on Motorola Xoom.
Questions:
Has anyone experienced this kind of behavior?
Can anyone provide me any direction as to other tools to help me research a possible memory leak?
Is there a system process that I can look at to show me in detail how the device memory is being allocated?
Thanks for your time.

Memory leaks in native code can create the symptoms that you're describing: system memory slowly bleeds away while the app's memory footprint (as seen by the JVM) stays more or less constant.
I suggest looking carefully through the memory allocations in your native code and verifying that each one is being cleaned up. This includes calls to malloc, any objects created on the heap (i.e., with "new"), and so forth. There is some tool support for profiling native allocations with DDMS -- see this answer.

Upon further analysis, what I can deduce is that there were three main problems of my memory leaks:
I had initially placed all the UI creation code in the Overridden onStart method because I was unclear of the appropriate location for it (onStart vs onCreateView). I moved all UI code into onCreateView (anything that is related to this.getView() -> use your inflater in the onCreateView). This seemed to eliminate a memory leak that occurred every time I opened and closed the app continuously. Here's a recommendation:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View v = inflater.inflate(R.layout.fragment_one, container, false);
//ALL UI code here using "v"
return v;
}
I was using a ViewPager to house all my fragments (this was because of the specific type of navigation I needed). I switched this to using a custom fragment management solution. I would recommend the use of fragment transaction manager (I originally thought that the fragment manager was causing the leak, but it doesn't appear to be). This wasn't causing a leak, but was eating up a significant amount of memory.
WebViews are a significant cause of memory leaks as well (as its been well documented throughout the internet). I tried using a solution posted which was to wrap the webview in a container and destroy both the webview and its container (Here's the code)
#Override
public void onDestroy()
{
super.onDestroy();
if (mWebContainer != null)
mWebContainer.removeAllViews();
if (mWebView != null)
{
mWebView.loadUrl("about:blank");
mWebView.destroy();
mWebView = null;
}
}
This did not fix my webview issue, but maybe it will fix someone else's out there. I'm continuing to search for the problem. My scenario includes multiple fragments that each have a webview that can open up additional fragments with webviews.
I hope this helps others, I was stuck for over a month debugging all the different scenarios causing leaks as I didn't consider originally that there were many causes. Good luck. Thanks SO community as always.

I found the primary cause of my memory leak. It was around executing a shell command by creating a Process object and opening up input and output streams. I used this to detect rooted devices. I'm not enough of an expert on the Process class to explain why this is causing leaks (I'm going to read up on it now), but if you're using code similar to this I'd be alert to this issue.
public static enum SHELL_COMMAND
{
check_su_binary(new String[] { "/system/xbin/which", "su" }), ;
String[] command;
SHELL_COMMAND(String[] command)
{
this.command = command;
}
}
/**
* #param shellCommand
* #return
*/
public List<String> executeCommand(SHELL_COMMAND shellCommand)
{
//this code was causing my memory leak
try
{
String line = null;
List<String> fullResponse = new ArrayList<String>();
Process localProcess = Runtime.getRuntime().exec(shellCommand.command);
OutputStreamWriter writer = new OutputStreamWriter(localProcess.getOutputStream());
BufferedWriter bufferedWriter = new BufferedWriter(writer);
InputStreamReader reader = new InputStreamReader(localProcess.getInputStream());
BufferedReader in = new BufferedReader(reader);
while ((line = in.readLine()) != null)
{
fullResponse.add(line);
}
}
catch (Exception e)
{
e.printStackTrace();
}
try
{
bufferedWriter.close();
bufferedWriter = null;
writer.close();
writer = null;
in.close();
in = null;
reader.close();
reader = null;
}
catch (IOException e)
{
e.printStackTrace();
}
return fullResponse;
}

Memory leak in CardboardActivity

While profiling my Google Cardboard application, I found out a very large memory leak (15Mb!) each time I left the activity with the 3D graphics.
After a long and grievous investigation, I found out that the source of the problem was a Context leak that happened each time I closed my CardboardActivity subclass.
The solution can be found in the accepted answer*
* wow... this is awkward... Note for any kind (and experienced) reviewer: I am writing a question to whom I know the answer already: am I supposed to do something for style, like add some fake suspense ("will our heroes prevail?! Find out in the accepted answer!"), like in a old Batman TV series or something?

After dicing and slicing my CardboardActivity subclass, until nothing else but the base class remained, I had to conclude that the base class itself was leaking the context.
I searched the web and found this post explaining how the activity in question leaked the context by failing to un-register a listener with a private instance of a class.
Upon trying to invoke said method manually (using reflection), I found out that in the current version of the Cardboard SDK (0.5.4 at the time of writing), the field is not present anymore.
Long story short: all sensors are now handled by an undocumented (yet public) SensorConnection class instantiated in CardboardActivity as a sensorConnection field, which is still plagued by the bug detailed in my first link.
This led me to this solution:
get the sensorConnection field in the CardboardActivity by reflection
use it to get the magneticSensor field, again by reflection
invoke the setOnCardboardTheaterListener with null argument, to clear the binding holding the reference to the Context in the Activity onDestroy method.
this boils down to the following code:
private void workAroundLeak() {
try {
// Get the sensor Connection
Class<?> c1 = Class.forName("com.google.vrtoolkit.cardboard.CardboardActivity");
Field sensorsField = c1.getDeclaredField("sensorConnection");
sensorsField.setAccessible(true);
SensorConnection sc = (SensorConnection) sensorsField.get(this);
if(sc == null) return;
// Get the magnetSensor
Class<?> c2 = Class.forName("com.google.vrtoolkit.cardboard.sensors.SensorConnection");
Field magnetField = c2.getDeclaredField("magnetSensor");
magnetField.setAccessible(true);
MagnetSensor ms = (MagnetSensor) magnetField.get(sc);
if(ms == null) return;
ms.setOnCardboardTriggerListener(null);
} catch(Exception e) {}
}
#Override
protected void onDestroy() {
workAroundLeak();
super.onDestroy();
}
which solved the problem entirely.
A word to the wise: since this solution relies on reflection, it might break (without consequences other than doing nothing, likely) as soon as Google will update the SDK (possibly fixing the issue in a clean way).
Hope this helps someone

Rotation bitmap causes TransactionTooLargeException in Android widget [duplicate]

I got a TransactionTooLargeException. Not reproducible. In the docs it says
The Binder transaction failed because it was too large.
During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown.
...
There are two possible outcomes when a remote procedure call throws TransactionTooLargeException. Either the client was unable to send its request to the service (most likely if the arguments were too large to fit in the transaction buffer), or the service was unable to send its response back to the client (most likely if the return value was too large to fit in the transaction buffer).
...
So somewhere I'm passing or receiving arguments which exceed some unknown limit. Where?
The stacktrace doesn't show anything useful:

It seems to be related with views? How is this related to remote procedure call?
Maybe important: Android version: 4.0.3, Device: HTC One X

I encountered this issue, and I found that when there huge amount of data getting exchanged between a service and an application,(This involves transferring lots of thumbnails). Actually data size was around 500kb, and the IPC transaction buffer size is set to 1024KB. I am not sure why it exceeded the transaction buffer.
This also can occur, when you pass lot of data through intent extras
When you get this exception in your application, please analyze your code.
Are you exchanging lot of data between your services and application?
Using intents to share huge data, (for example, the user selects huge number of files from gallery share press share, the URIs of the selected files will be transferred using intents)
receiving bitmap files from service
waiting for android to respond back with huge data (for example, getInstalledApplications() when the user installed lot of applications)
using applyBatch() with lot of operations pending
How to handle when you get this exception
If possible, split the big operation in to small chunks, for example, instead of calling applyBatch() with 1000 operations, call it with 100 each.
Do not exchange huge data (>1MB) between services and application
I dont know how to do this, but, Do not query android, which can return huge data :-)

If you need to investigate which Parcel is causing your crash, you should consider trying TooLargeTool.
(I found this as a comment from #Max Spencer under the accepted answer and it was helpful in my case.)

This is not a definitive answer, but it may shed some light on the causes of a TransactionTooLargeException and help pinpoint the problem.
Although most answers refer to large amounts of data transferred, I see this exception being thrown incidentally after heavy scrolling and zooming and repeatedly opening an ActionBar spinner menu. The crash happens on tapping the action bar. (this is a custom mapping app)
The only data being passed around seem to be touches from the "Input Dispatcher" to the app. I think this cannot reasonably amount to anywhere near 1 mb in the "Transaction Buffer".
My app is running on a quad core 1.6 GHz device and uses 3 threads for heavylifting, keeping one core free for the UI thread. Furthermore, the app uses android:largeHeap, has 10 mb of unused heap left and has 100 mb of room left to grow the heap. So I wouldn't say it is a resource issue.
The crash is always immediately preceded by these lines:
W/InputDispatcher( 2271): channel ~ Consumer closed input channel or an error occurred. events=0x9
E/InputDispatcher( 2271): channel ~ Channel is unrecoverably broken and will be disposed!
E/JavaBinder(28182): !!! FAILED BINDER TRANSACTION !!!
Which are not neccesarily printed in that order, but (as far as I checked) happen on the same millisecond.
And the stack trace itself, for clarity, is the same as in the question:
E/AndroidRuntime(28182): java.lang.RuntimeException: Adding window failed
..
E/AndroidRuntime(28182): Caused by: android.os.TransactionTooLargeException
Delving into the source code of android one finds these lines:
frameworks/base/core/jni/android_util_Binder.cpp:
case FAILED_TRANSACTION:
ALOGE("!!! FAILED BINDER TRANSACTION !!!");
// TransactionTooLargeException is a checked exception, only throw from certain methods.
// FIXME: Transaction too large is the most common reason for FAILED_TRANSACTION
// but it is not the only one. The Binder driver can return BR_FAILED_REPLY
// for other reasons also, such as if the transaction is malformed or
// refers to an FD that has been closed. We should change the driver
// to enable us to distinguish these cases in the future.
jniThrowException(env, canThrowRemoteException
? "android/os/TransactionTooLargeException"
: "java/lang/RuntimeException", NULL);
To me it sounds like I'm possibly hitting this undocumented feature, where the transaction fails for other reasons than a Transaction being TooLarge. They should have named it TransactionTooLargeOrAnotherReasonException.
At this time I did not solve the issue, but if I find something useful I will update this answer.
update: it turned out my code leaked some file descriptors, the number of which is maximized in linux (typically 1024), and this seems to have triggered the exception. So it was a resource issue after all. I verified this by opening /dev/zero 1024 times, which resulted in all kinds of weird exceptions in UI related actions, including the exception above, and even some SIGSEGV's. Apparently failure to open a file/socket is not something which is handled/reported very cleanly throughout Android.

The TransactionTooLargeException has been plaguing us for about 4 months now, and we've finally resolved the issue!
What was happening was we are using a FragmentStatePagerAdapter in a ViewPager. The user would page through and create 100+ fragments (its a reading application).
Although we manage the fragments properly in destroyItem(), in Androids
implementation of FragmentStatePagerAdapter there is a bug, where it kept a reference to the following list:
private ArrayList<Fragment.SavedState> mSavedState = new ArrayList<Fragment.SavedState>();
And when the Android's FragmentStatePagerAdapter attempts to save the state, it will call the function
#Override
public Parcelable saveState() {
Bundle state = null;
if (mSavedState.size() > 0) {
state = new Bundle();
Fragment.SavedState[] fss = new Fragment.SavedState[mSavedState.size()];
mSavedState.toArray(fss);
state.putParcelableArray("states", fss);
}
for (int i=0; i<mFragments.size(); i++) {
Fragment f = mFragments.get(i);
if (f != null && f.isAdded()) {
if (state == null) {
state = new Bundle();
}
String key = "f" + i;
mFragmentManager.putFragment(state, key, f);
}
}
return state;
}
As you can see, even if you properly manage the fragments in the FragmentStatePagerAdapter subclass, the base class will still store an Fragment.SavedState for every single fragment ever created. The TransactionTooLargeException would occur when that array was dumped to a parcelableArray and the OS wouldn't like it 100+ items.
Therefore the fix for us was to override the saveState() method and not store anything for "states".
#Override
public Parcelable saveState() {
Bundle bundle = (Bundle) super.saveState();
bundle.putParcelableArray("states", null); // Never maintain any states from the base class, just null it out
return bundle;
}

For those who bitterly disappointed in search of answer of why the TransactionTooLargeException apears, try to check how much information you save in instance state.
On compile/targetSdkVersion <= 23 we have only internal warning about large size of saved state, but nothing is crashed:

What to do?
Save data in local database and keep only id's in instance state which you can use to retrieve this data.

This exception is typically thrown when the app is being sent to the background.
So I've decided to use the data Fragment pattern to completely circumvent the onSavedInstanceState lifecycle. My solution also handles complex instance states and frees memory ASAP.
First I've created a simple Fargment to store the data:
package info.peakapps.peaksdk.logic;
import android.app.Fragment;
import android.app.FragmentManager;
import android.os.Bundle;
/**
* A neat trick to avoid TransactionTooLargeException while saving our instance state
*/
public class SavedInstanceFragment extends Fragment {
private static final String TAG = "SavedInstanceFragment";
private Bundle mInstanceBundle = null;
public SavedInstanceFragment() { // This will only be called once be cause of setRetainInstance()
super();
setRetainInstance( true );
}
public SavedInstanceFragment pushData( Bundle instanceState )
{
if ( this.mInstanceBundle == null ) {
this.mInstanceBundle = instanceState;
}
else
{
this.mInstanceBundle.putAll( instanceState );
}
return this;
}
public Bundle popData()
{
Bundle out = this.mInstanceBundle;
this.mInstanceBundle = null;
return out;
}
public static final SavedInstanceFragment getInstance(FragmentManager fragmentManager )
{
SavedInstanceFragment out = (SavedInstanceFragment) fragmentManager.findFragmentByTag( TAG );
if ( out == null )
{
out = new SavedInstanceFragment();
fragmentManager.beginTransaction().add( out, TAG ).commit();
}
return out;
}
}
Then on my main Activity I circumvent the saved instance cycle completely, and defer the responsibility to my data Fragment. No need to use this on the Fragments themselves, since their state is added to the Activity's state automatically):
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
SavedInstanceFragment.getInstance( getFragmentManager() ).pushData( (Bundle) outState.clone() );
outState.clear(); // We don't want a TransactionTooLargeException, so we handle things via the SavedInstanceFragment
}
What's left is simply to pop the saved instance:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(SavedInstanceFragment.getInstance(getFragmentManager()).popData());
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState( SavedInstanceFragment.getInstance( getFragmentManager() ).popData() );
}
Full details: http://www.devsbedevin.net/avoiding-transactiontoolargeexception-on-android-nougat-and-up/

There isn't one specific cause of this problem.For me, in my Fragment class I was doing this:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View rootView = inflater.inflate(R.layout.snacks_layout, container); //<-- notice the absence of the false argument
return rootView;
}
instead of this:
View rootView = inflater.inflate(R.layout.softs_layout, container, false);

It is important to understand that the transaction buffer is limited to 1 MB, regardless of device capabilities or app. This buffer is used with every API calls you make and is shared amongst all transactions an app is currently running.
I believe it also holds some specific object like parcels and such (Parcel.obtain()), so it's important to always match every obtain() with a recycle().
This error can easily happen on API calls returning a lot of data, even though the returned data is less than 1 MB (if other transactions are still running).
For example, the PackageManager.getInstalledApplication() call returns a list of all apps installed. Adding specific flags allows to retrieve a lot of extra data. Doing so is likely to fail, so it's recommended not to retrieve any extra data and retrieve those on a per-app basis.
However the call may still fail, so it's important to surround it with a catch and be able to retry if necessary.
As far as I know, there's no work-around to such issue except retrying and making sure to retrieve as little information as possible.

I too got this exception on a Samsung S3.
I suspect 2 root causes,
you have bitmaps that load and take up too much memory, use downsizing
You have some drawables missing from the drawable-_dpi folders, android looks for them in drawable, and resizes them, making your setContentView suddenly jump and use a lot of memory.
Use DDMS and look at your heap as you play your app, that will give you some indication on which setcontentview is creating the issue.
I copied all the drawables across all folders to get rid of problem 2.
Issue is resolved.

Add this to your Activity
#Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
super.onSaveInstanceState(oldInstanceState);
oldInstanceState.clear();
}
It works for me hope also it will help you

This may Happen because Activity "A" may have Fragments and when you navigate to Activity "B" .
then Activity Life Cycle of activty "A" will be
OnResume->OnPause()->OnSavedInsanceState()
here in OnSavedInsanceState may cause crash because it couldnt save state with to much data. so to try to clear the saveInsatnce of the Activity "A" by adding following code.
#Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
super.onSaveInstanceState(oldInstanceState);
if (oldInstanceState != null) {
oldInstanceState.clear();
}
}

Our app also has this problem. After testing, it is found that when the application memory is insufficient and the activity is recycled, the system calls the onSaveInstanceState method to save a large amount of bundle data, and the data becomes large every time, and finally a TransactionTooLargeException error will be reported, so I think of this method should be able to solve this problem.
public final int MAX_BUNDLE_SIZE = 300;
#Override
protected void onSaveInstanceState(#NonNull Bundle outState) {
super.onSaveInstanceState(outState);
long bundleSize = getBundleSize(outState);
if (bundleSize > MAX_BUNDLE_SIZE * 1024) {
outState.clear();
}
}
private long getBundleSize(Bundle bundle) {
long dataSize;
Parcel obtain = Parcel.obtain();
try {
obtain.writeBundle(bundle);
dataSize = obtain.dataSize();
} finally {
obtain.recycle();
}
return dataSize;
}

So for us it was we were trying to send too large of an object through our AIDL interface to a remote service. The transaction size cannot exceed 1MB. The request is broken down into separate chunks of 512KB and sent one at a time through the interface. A brutal solution I know but hey - its Android :(

I faced with the same issue when I tried to send bitmap via Intent and at the same time when it happens I folded the application.
How it described in this article enter link description here it happens when an Activity is in the process of stopping, that means that the Activity was trying to send its saved state Bundles to the system OS for safe keeping for restoration later (after a config change or process death) but that one or more of the Bundles it sent were too large.
I solved it via hack by overriding onSaveInstanceState in my Activity:
#Override
protected void onSaveInstanceState(Bundle outState) {
// super.onSaveInstanceState(outState);
}
and comment call super. It is a dirty hack but it is working perfectly. Bitmap was successfully sent without crashes.
Hope this will help someone.

Recently I also have encountered with an interesting case while working with Android's Contacts Provider.
I needed to load photos of contacts from internal contacts database and according to the system architecture all of this data are delivered by queries to Contacts Provider.
As it works as a separate application - all kinds of data transferring are performed by using Binder mechanism and so Binder buffer comes into play here.
My main mistake was that I didn't close the Cursor with blob data gotten from Contacts Provider, so that the memory allocated for the provider increased and this inflated the Binder buffer until I got tons of !!!FAILED BINDER TRANSACTION!!! messages in my LogCat output.
So the main idea is that when you work with external Content Providers and got Cursors from them, always close it when you finish to work with them.

You have clear your old InstanceState from onSaveInstanceState method, and it will work well. I am using FragmentStatePagerAdapter for my viewpager so I keep below Override method into my parent activity for clear InstanceState.
#Override
protected void onSaveInstanceState(Bundle InstanceState) {
super.onSaveInstanceState(InstanceState);
InstanceState.clear();
}
I found this solution from here android.os.TransactionTooLargeException on Nougat

Make sure that you do not put into Intent object data of large size. In my case I was adding String 500k size and then starting another activity. It always failed with this exception. I avoided sharing data between activities by using static variables of activities - you don't have to send them to Intent and then pulling from it.
What I had:
String html = new String();//some string of 500K data.
Intent intent = new Intent(MainActivity.this, PageWebView.class);
//this is workaround - I just set static variable and then access it from another activity.
MainActivity.htmlBody = timelineDb.getHTMLBodyForTweet(tweet);
//This line was present and it actually failed with the same exception you had.
//intent.putExtra("com.gladimdim.offtie.webview", html);

In my case I get TransactionTooLargeException as a secondary crash after the native library crashed with SIGSEGV. The native library crash is not reported so I only receive TransactionTooLargeException.

I got this in my syncadapter when trying to bulkInsert a large ContentValues[]. I decided to fix it as follows:
try {
count = provider.bulkInsert(uri, contentValueses);
} catch (TransactionTooLarge e) {
int half = contentValueses.length/2;
count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, 0, half));
count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, half, contentValueses.length));
}

For me it was also the FragmentStatePagerAdapter, however overriding saveState() did not work. Here's how I fixed it:
When calling the FragmentStatePagerAdapter constructor, keep a separate list of fragments within the class, and add a method to remove the fragments:
class PagerAdapter extends FragmentStatePagerAdapter {
ArrayList<Fragment> items;
PagerAdapter(ArrayList<Fragment> frags) {
super(getFragmentManager()); //or getChildFragmentManager() or getSupportFragmentManager()
this.items = new ArrayList<>();
this.items.addAll(frags);
}
public void removeFragments() {
Iterator<Fragment> iter = items.iterator();
while (iter.hasNext()) {
Fragment item = iter.next();
getFragmentManager().beginTransaction().remove(item).commit();
iter.remove();
}
notifyDataSetChanged();
}
}
//...getItem() and etc methods...
}
Then in the Activity, save the ViewPager position and call adapter.removeFragments() in the overridden onSaveInstanceState() method:
private int pagerPosition;
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//save other view state here
pagerPosition = mViewPager.getCurrentItem();
adapter.removeFragments();
}
Lastly, in the overridden onResume() method, re-instantiate the adapter if it isn't null. (If it's null, then the Activity is being opened for the first time or after the app has been killed off by Android, in which onCreate will do the adapter creation.)
#Override
public void onResume() {
super.onResume();
if (adapter != null) {
adapter = new PagerAdapter(frags);
mViewPager.setAdapter(adapter);
mViewPager.setCurrentItem(currentTabPosition);
}
}

This was happening in my app because I was passing a list of search results in a fragment's arguments, assigning that list to a property of the fragment - which is actually a reference to the same location in memory pointed to by the fragment's arguments - then adding new items to the list, which also changed the size of the fragment's arguments. When the activity is suspended, the base fragment class tries to save the fragment's arguments in onSaveInstanceState, which crashes if the arguments are larger than 1MB. For example:
private ArrayList<SearchResult> mSearchResults;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {
mSearchResults = (ArrayList) getArguments().getSerializable("SearchResults");
}
}
private void onSearchResultsObtained(ArrayList<SearchResult> pSearchResults) {
// Because mSearchResults points to the same location in memory as the fragment's arguments
// this will also increase the size of the arguments!
mSearchResults.addAll(pSearchResults);
}
The easiest solution in this case was to assign a copy of the list to the fragment's property instead of assigning a reference:
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {
// Copy value of array instead of reference
mSearchResults = new ArrayList((ArrayList) getArguments().getSerializable("SearchResults"));
}
}
An even better solution would be to not pass around so much data in the arguments.
I probably never would have found this without the help of this answer and TooLargeTool.

When I am dealing with the WebView in my app it happens. I think it's related to addView and UI resources.
In my app I add some code in WebViewActivity like this below then it runs ok:
#Override
protected void onDestroy() {
if (mWebView != null) {
((ViewGroup) mWebView.getParent()).removeView(mWebView);
mWebView.removeAllViews();
mWebView.destroy();
}
super.onDestroy();
}

I found the root cause of this (we got both "adding window failed" and file descriptor leak as mvds says).
There is a bug in BitmapFactory.decodeFileDescriptor() of Android 4.4.
It only occurs when inPurgeable and inInputShareable of BitmapOptions are set to true. This causes many problem in many places interact with files.
Note that the method is also called from MediaStore.Images.Thumbnails.getThumbnail().
Universal Image Loader is affected by this issue. Picasso and Glide seems to be not affected.
https://github.com/nostra13/Android-Universal-Image-Loader/issues/1020

This one line of code in writeToParcel(Parcel dest, int flags) method helped me to get rid of TransactionTooLargeException.
dest=Parcel.obtain();
After this code only i am writing all data to the parcel object i.e dest.writeInt() etc.

Try to use EventBus or ContentProvider like solution.
If you are in the same process(normally all your activities would be), try to use EventBus, cause in process data exchange does NOT need a somewhat buffer, so you do not need to worry about your data is too large. (You can just use method call to pass data indeed, and EventBus hide the ugly things)
Here is the detail:
// one side
startActivity(intentNotTooLarge);
EventBus.getDefault().post(new FooEvent(theHugeData));
// the other side
#Subscribe public void handleData(FooEvent event) { /* get and handle data */ }
If the two sides of Intent are not in the same process, try somewhat ContentProvider.
See TransactionTooLargeException
The Binder transaction failed because it was too large.
During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown.

I got a TransactionTooLargeException from a Stackoverflow error in a Android Espresso test. I found the stackoverflow error stack trace in the logs when I took off the Logcat filter for my app.
I'm guessing that Espresso caused the TransactionTooLargeException when trying to handle a really large exception stacktrace.

Also i was facing this issue for Bitmap data passing from one activity to another but i make a solution by making my data as static data and this is working perfect for me
In activity first :
public static Bitmap bitmap_image;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
bitmap_image=mybitmap;
}
and in second activity :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Bitmap mybitmap=first.bitmap_image;
}

I have also lived TransactionTooLargeException. Firstly I have worked on understand where it occurs. I know the reason why it occurs. Every of us know because of large content. My problem was like that and I solved. Maybe this solution can be useful for anybody.
I have an app that get content from api. I am getting result from API in first screen and send it to second screen. I can send this content to second screen in successful. After second screen if I want to go third screen this exception occurs. Each of my screen is created from Fragment. I noticed that when I leave from second screen. It saves its bundle content. if this content is too large this exception happens. My solution is after I got content from bundle I clear it.
class SecondFragment : BaseFragment() {
lateinit var myContent: MyContent
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
myContent = arguments?.getParcelable("mycontent")
arguments?.clear()
}

If you converted Bitmap into Base64 in projects and save it to parcelable object you shuold resize bitmap with below code ,
replace png with jpeg and replace quality 100 to 75 or 60 :
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, byteArrayOutputStream)
this solution works for me

sometime Activity include some Fragment when Activityneed to totally recreate Fragments content,
if the sportFragmentManager.fragments without clear history fragments
val fragments = sportFragmentManager.fragments
val transaction = sportFragmentManager.beginTransaction()
for (frag in fragments){
transaction.remove(frag)
}
transaction.commitAllowingStateLoss()
serveral times recreate Fragments the Activity will happen (debug use tooLargeTool)

Android StrictMode and heap dumps

When Android's StrictMode detects a leaked object (e.g. activity) violation, it would be helpful if I could capture a heap dump at that moment in time. There's no obvious way, however, to configure it to do this. Does anyone know of some trick that can be used to achieve it, e.g. a way to convince the system to run a particular piece of code just prior to the death penalty being invoked? I don't think StrictMode throws an exception, so I can't use the trick described here: Is there a way to have an Android process produce a heap dump on an OutOfMemoryError?

No exception, but StrictMode does print a message to System.err just before it terminates. So, this is a hack, but it works, and as it's only going to be enabled on debug builds I figure it's fine... :)
in onCreate():
//monitor System.err for messages that indicate the process is about to be killed by
//StrictMode and cause a heap dump when one is caught
System.setErr (new HProfDumpingStderrPrintStream (System.err));
and the class referred to:
private static class HProfDumpingStderrPrintStream extends PrintStream
{
public HProfDumpingStderrPrintStream (OutputStream destination)
{
super (destination);
}
#Override
public synchronized void println (String str)
{
super.println (str);
if (str.equals ("StrictMode VmPolicy violation with POLICY_DEATH; shutting down."))
{
// StrictMode is about to terminate us... don't let it!
super.println ("Trapped StrictMode shutdown notice: logging heap data");
try {
android.os.Debug.dumpHprofData(app.getDir ("hprof", MODE_WORLD_READABLE) + "/strictmode-death-penalty.hprof");
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
(where app is a static field in the outer class containing a reference to the application context, for ease of reference)
The string it matches has survived unchanged from gingerbread release all the way up to jelly bean, but it could theoretically change in future versions, so it's worth checking new releases to ensure they still use the same message.

TransactionTooLargeEception when trying to get a list of applications installed

As part of my app I get a list of apps installed on the device by using ApplicationPackageManager.getInstalledApplications but for some users I get crash reports saying that
TransactionTooLargeException at android.osBinderProxy.tranasact(Native Method)
Can anyone think why I'd get this?

I've found that this was solved on Android 5.1 (proof here, search for "Fix package manager TransactionTooLargeExceptions") as it was reported on multiple places:
https://code.google.com/p/android/issues/detail?id=95749
https://code.google.com/p/android/issues/detail?id=93717
https://code.google.com/p/android/issues/detail?id=69276
However, I wanted to solve this for pre-5.1, so I've come up with a solution (and suggested Google to put it on the support library, here) . Here's a short code version of what I've suggested:
public static List<PackageInfo> getInstalledPackages(Context context,int flags)
{
final PackageManager pm=context.getPackageManager();
try
{
return pm.getInstalledPackages(flags);
}
catch(Exception ignored)
{
//we don't care why it didn't succeed. We'll do it using an alternative way instead
}
// use fallback:
Process process;
List<PackageInfo> result=new ArrayList<>();
BufferedReader bufferedReader=null;
try
{
process=Runtime.getRuntime().exec("pm list packages");
bufferedReader=new BufferedReader(new InputStreamReader(process.getInputStream()));
String line;
while((line=bufferedReader.readLine())!=null)
{
final String packageName=line.substring(line.indexOf(':')+1);
final PackageInfo packageInfo=pm.getPackageInfo(packageName,flags);
result.add(packageInfo);
}
process.waitFor();
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
if(bufferedReader!=null)
try
{
bufferedReader.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
return result;
}
What it does it to try using the official way first, and then, if failed, it fetches the package names using ADB command, and get the information of each of the apps, one after another.
It is much slower than the official one, but it didn't crash for me. I've tested it on Android emulators (2.3.x till 5.0.x, including), and on real devices too.
The time it took on my device (Galaxy S3 with custom rom of Android 5.1) is 1375-2012 ms (on 197 apps total) compared to 37-65 ms using the official way .
EDIT: people claim here that it's not fixed on Android 5.1 . I hope that it got fixed on Android 6 .

This exception is kind of difficult to reproduce under normal circumstances. You will get this exception when there IPC memory is exhausted when transferring data. This can occur in both cases, where a service is trying to place data to client or a client is sending data to service. Most probably some of your users might have installed huge number of application, which results in a data size greater than 1MB (which is the size of IPC buffer).
I am afraid in this case, you will not be do anything better. But if you are doing something like, applyBatch, you can separate one large transaction to multiple smaller transactions.
Also have a look at this thread What to do on TransactionTooLargeException

What to do on TransactionTooLargeException

I got a TransactionTooLargeException. Not reproducible. In the docs it says
The Binder transaction failed because it was too large.
During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown.
...
There are two possible outcomes when a remote procedure call throws TransactionTooLargeException. Either the client was unable to send its request to the service (most likely if the arguments were too large to fit in the transaction buffer), or the service was unable to send its response back to the client (most likely if the return value was too large to fit in the transaction buffer).
...
So somewhere I'm passing or receiving arguments which exceed some unknown limit. Where?
The stacktrace doesn't show anything useful:

It seems to be related with views? How is this related to remote procedure call?
Maybe important: Android version: 4.0.3, Device: HTC One X

I encountered this issue, and I found that when there huge amount of data getting exchanged between a service and an application,(This involves transferring lots of thumbnails). Actually data size was around 500kb, and the IPC transaction buffer size is set to 1024KB. I am not sure why it exceeded the transaction buffer.
This also can occur, when you pass lot of data through intent extras
When you get this exception in your application, please analyze your code.
Are you exchanging lot of data between your services and application?
Using intents to share huge data, (for example, the user selects huge number of files from gallery share press share, the URIs of the selected files will be transferred using intents)
receiving bitmap files from service
waiting for android to respond back with huge data (for example, getInstalledApplications() when the user installed lot of applications)
using applyBatch() with lot of operations pending
How to handle when you get this exception
If possible, split the big operation in to small chunks, for example, instead of calling applyBatch() with 1000 operations, call it with 100 each.
Do not exchange huge data (>1MB) between services and application
I dont know how to do this, but, Do not query android, which can return huge data :-)

If you need to investigate which Parcel is causing your crash, you should consider trying TooLargeTool.
(I found this as a comment from #Max Spencer under the accepted answer and it was helpful in my case.)

The TransactionTooLargeException has been plaguing us for about 4 months now, and we've finally resolved the issue!
What was happening was we are using a FragmentStatePagerAdapter in a ViewPager. The user would page through and create 100+ fragments (its a reading application).
Although we manage the fragments properly in destroyItem(), in Androids
implementation of FragmentStatePagerAdapter there is a bug, where it kept a reference to the following list:
private ArrayList<Fragment.SavedState> mSavedState = new ArrayList<Fragment.SavedState>();
And when the Android's FragmentStatePagerAdapter attempts to save the state, it will call the function
#Override
public Parcelable saveState() {
Bundle state = null;
if (mSavedState.size() > 0) {
state = new Bundle();
Fragment.SavedState[] fss = new Fragment.SavedState[mSavedState.size()];
mSavedState.toArray(fss);
state.putParcelableArray("states", fss);
}
for (int i=0; i<mFragments.size(); i++) {
Fragment f = mFragments.get(i);
if (f != null && f.isAdded()) {
if (state == null) {
state = new Bundle();
}
String key = "f" + i;
mFragmentManager.putFragment(state, key, f);
}
}
return state;
}
As you can see, even if you properly manage the fragments in the FragmentStatePagerAdapter subclass, the base class will still store an Fragment.SavedState for every single fragment ever created. The TransactionTooLargeException would occur when that array was dumped to a parcelableArray and the OS wouldn't like it 100+ items.
Therefore the fix for us was to override the saveState() method and not store anything for "states".
#Override
public Parcelable saveState() {
Bundle bundle = (Bundle) super.saveState();
bundle.putParcelableArray("states", null); // Never maintain any states from the base class, just null it out
return bundle;
}

For those who bitterly disappointed in search of answer of why the TransactionTooLargeException apears, try to check how much information you save in instance state.
On compile/targetSdkVersion <= 23 we have only internal warning about large size of saved state, but nothing is crashed:

What to do?
Save data in local database and keep only id's in instance state which you can use to retrieve this data.

This exception is typically thrown when the app is being sent to the background.
So I've decided to use the data Fragment pattern to completely circumvent the onSavedInstanceState lifecycle. My solution also handles complex instance states and frees memory ASAP.
First I've created a simple Fargment to store the data:
package info.peakapps.peaksdk.logic;
import android.app.Fragment;
import android.app.FragmentManager;
import android.os.Bundle;
/**
* A neat trick to avoid TransactionTooLargeException while saving our instance state
*/
public class SavedInstanceFragment extends Fragment {
private static final String TAG = "SavedInstanceFragment";
private Bundle mInstanceBundle = null;
public SavedInstanceFragment() { // This will only be called once be cause of setRetainInstance()
super();
setRetainInstance( true );
}
public SavedInstanceFragment pushData( Bundle instanceState )
{
if ( this.mInstanceBundle == null ) {
this.mInstanceBundle = instanceState;
}
else
{
this.mInstanceBundle.putAll( instanceState );
}
return this;
}
public Bundle popData()
{
Bundle out = this.mInstanceBundle;
this.mInstanceBundle = null;
return out;
}
public static final SavedInstanceFragment getInstance(FragmentManager fragmentManager )
{
SavedInstanceFragment out = (SavedInstanceFragment) fragmentManager.findFragmentByTag( TAG );
if ( out == null )
{
out = new SavedInstanceFragment();
fragmentManager.beginTransaction().add( out, TAG ).commit();
}
return out;
}
}
Then on my main Activity I circumvent the saved instance cycle completely, and defer the responsibility to my data Fragment. No need to use this on the Fragments themselves, since their state is added to the Activity's state automatically):
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
SavedInstanceFragment.getInstance( getFragmentManager() ).pushData( (Bundle) outState.clone() );
outState.clear(); // We don't want a TransactionTooLargeException, so we handle things via the SavedInstanceFragment
}
What's left is simply to pop the saved instance:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(SavedInstanceFragment.getInstance(getFragmentManager()).popData());
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState( SavedInstanceFragment.getInstance( getFragmentManager() ).popData() );
}
Full details: http://www.devsbedevin.net/avoiding-transactiontoolargeexception-on-android-nougat-and-up/

There isn't one specific cause of this problem.For me, in my Fragment class I was doing this:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View rootView = inflater.inflate(R.layout.snacks_layout, container); //<-- notice the absence of the false argument
return rootView;
}
instead of this:
View rootView = inflater.inflate(R.layout.softs_layout, container, false);

It is important to understand that the transaction buffer is limited to 1 MB, regardless of device capabilities or app. This buffer is used with every API calls you make and is shared amongst all transactions an app is currently running.
I believe it also holds some specific object like parcels and such (Parcel.obtain()), so it's important to always match every obtain() with a recycle().
This error can easily happen on API calls returning a lot of data, even though the returned data is less than 1 MB (if other transactions are still running).
For example, the PackageManager.getInstalledApplication() call returns a list of all apps installed. Adding specific flags allows to retrieve a lot of extra data. Doing so is likely to fail, so it's recommended not to retrieve any extra data and retrieve those on a per-app basis.
However the call may still fail, so it's important to surround it with a catch and be able to retry if necessary.
As far as I know, there's no work-around to such issue except retrying and making sure to retrieve as little information as possible.

I too got this exception on a Samsung S3.
I suspect 2 root causes,
you have bitmaps that load and take up too much memory, use downsizing
You have some drawables missing from the drawable-_dpi folders, android looks for them in drawable, and resizes them, making your setContentView suddenly jump and use a lot of memory.
Use DDMS and look at your heap as you play your app, that will give you some indication on which setcontentview is creating the issue.
I copied all the drawables across all folders to get rid of problem 2.
Issue is resolved.

Add this to your Activity
#Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
super.onSaveInstanceState(oldInstanceState);
oldInstanceState.clear();
}
It works for me hope also it will help you

This may Happen because Activity "A" may have Fragments and when you navigate to Activity "B" .
then Activity Life Cycle of activty "A" will be
OnResume->OnPause()->OnSavedInsanceState()
here in OnSavedInsanceState may cause crash because it couldnt save state with to much data. so to try to clear the saveInsatnce of the Activity "A" by adding following code.
#Override
protected void onSaveInstanceState(Bundle oldInstanceState) {
super.onSaveInstanceState(oldInstanceState);
if (oldInstanceState != null) {
oldInstanceState.clear();

Our app also has this problem. After testing, it is found that when the application memory is insufficient and the activity is recycled, the system calls the onSaveInstanceState method to save a large amount of bundle data, and the data becomes large every time, and finally a TransactionTooLargeException error will be reported, so I think of this method should be able to solve this problem.
public final int MAX_BUNDLE_SIZE = 300;
#Override
protected void onSaveInstanceState(#NonNull Bundle outState) {
super.onSaveInstanceState(outState);
long bundleSize = getBundleSize(outState);
if (bundleSize > MAX_BUNDLE_SIZE * 1024) {
outState.clear();
}
}
private long getBundleSize(Bundle bundle) {
long dataSize;
Parcel obtain = Parcel.obtain();
try {
obtain.writeBundle(bundle);
dataSize = obtain.dataSize();
} finally {
obtain.recycle();
}
return dataSize;
}

So for us it was we were trying to send too large of an object through our AIDL interface to a remote service. The transaction size cannot exceed 1MB. The request is broken down into separate chunks of 512KB and sent one at a time through the interface. A brutal solution I know but hey - its Android :(

I faced with the same issue when I tried to send bitmap via Intent and at the same time when it happens I folded the application.
How it described in this article enter link description here it happens when an Activity is in the process of stopping, that means that the Activity was trying to send its saved state Bundles to the system OS for safe keeping for restoration later (after a config change or process death) but that one or more of the Bundles it sent were too large.
I solved it via hack by overriding onSaveInstanceState in my Activity:
#Override
protected void onSaveInstanceState(Bundle outState) {
// super.onSaveInstanceState(outState);
}
and comment call super. It is a dirty hack but it is working perfectly. Bitmap was successfully sent without crashes.
Hope this will help someone.

Recently I also have encountered with an interesting case while working with Android's Contacts Provider.
I needed to load photos of contacts from internal contacts database and according to the system architecture all of this data are delivered by queries to Contacts Provider.
As it works as a separate application - all kinds of data transferring are performed by using Binder mechanism and so Binder buffer comes into play here.
My main mistake was that I didn't close the Cursor with blob data gotten from Contacts Provider, so that the memory allocated for the provider increased and this inflated the Binder buffer until I got tons of !!!FAILED BINDER TRANSACTION!!! messages in my LogCat output.
So the main idea is that when you work with external Content Providers and got Cursors from them, always close it when you finish to work with them.

You have clear your old InstanceState from onSaveInstanceState method, and it will work well. I am using FragmentStatePagerAdapter for my viewpager so I keep below Override method into my parent activity for clear InstanceState.
#Override
protected void onSaveInstanceState(Bundle InstanceState) {
super.onSaveInstanceState(InstanceState);
InstanceState.clear();
}
I found this solution from here android.os.TransactionTooLargeException on Nougat

Make sure that you do not put into Intent object data of large size. In my case I was adding String 500k size and then starting another activity. It always failed with this exception. I avoided sharing data between activities by using static variables of activities - you don't have to send them to Intent and then pulling from it.
What I had:
String html = new String();//some string of 500K data.
Intent intent = new Intent(MainActivity.this, PageWebView.class);
//this is workaround - I just set static variable and then access it from another activity.
MainActivity.htmlBody = timelineDb.getHTMLBodyForTweet(tweet);
//This line was present and it actually failed with the same exception you had.
//intent.putExtra("com.gladimdim.offtie.webview", html);

In my case I get TransactionTooLargeException as a secondary crash after the native library crashed with SIGSEGV. The native library crash is not reported so I only receive TransactionTooLargeException.

I got this in my syncadapter when trying to bulkInsert a large ContentValues[]. I decided to fix it as follows:
try {
count = provider.bulkInsert(uri, contentValueses);
} catch (TransactionTooLarge e) {
int half = contentValueses.length/2;
count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, 0, half));
count += provider.bulkInsert(uri, Arrays.copyOfRange(contentValueses, half, contentValueses.length));
}

For me it was also the FragmentStatePagerAdapter, however overriding saveState() did not work. Here's how I fixed it:
When calling the FragmentStatePagerAdapter constructor, keep a separate list of fragments within the class, and add a method to remove the fragments:
class PagerAdapter extends FragmentStatePagerAdapter {
ArrayList<Fragment> items;
PagerAdapter(ArrayList<Fragment> frags) {
super(getFragmentManager()); //or getChildFragmentManager() or getSupportFragmentManager()
this.items = new ArrayList<>();
this.items.addAll(frags);
}
public void removeFragments() {
Iterator<Fragment> iter = items.iterator();
while (iter.hasNext()) {
Fragment item = iter.next();
getFragmentManager().beginTransaction().remove(item).commit();
iter.remove();
}
notifyDataSetChanged();
}
}
//...getItem() and etc methods...
}
Then in the Activity, save the ViewPager position and call adapter.removeFragments() in the overridden onSaveInstanceState() method:
private int pagerPosition;
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//save other view state here
pagerPosition = mViewPager.getCurrentItem();
adapter.removeFragments();
}
Lastly, in the overridden onResume() method, re-instantiate the adapter if it isn't null. (If it's null, then the Activity is being opened for the first time or after the app has been killed off by Android, in which onCreate will do the adapter creation.)
#Override
public void onResume() {
super.onResume();
if (adapter != null) {
adapter = new PagerAdapter(frags);
mViewPager.setAdapter(adapter);
mViewPager.setCurrentItem(currentTabPosition);
}
}

This was happening in my app because I was passing a list of search results in a fragment's arguments, assigning that list to a property of the fragment - which is actually a reference to the same location in memory pointed to by the fragment's arguments - then adding new items to the list, which also changed the size of the fragment's arguments. When the activity is suspended, the base fragment class tries to save the fragment's arguments in onSaveInstanceState, which crashes if the arguments are larger than 1MB. For example:
private ArrayList<SearchResult> mSearchResults;
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {
mSearchResults = (ArrayList) getArguments().getSerializable("SearchResults");
}
}
private void onSearchResultsObtained(ArrayList<SearchResult> pSearchResults) {
// Because mSearchResults points to the same location in memory as the fragment's arguments
// this will also increase the size of the arguments!
mSearchResults.addAll(pSearchResults);
}
The easiest solution in this case was to assign a copy of the list to the fragment's property instead of assigning a reference:
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if (getArguments() != null && getArguments().getSerializable("SearchResults") != null) {
// Copy value of array instead of reference
mSearchResults = new ArrayList((ArrayList) getArguments().getSerializable("SearchResults"));
}
}
An even better solution would be to not pass around so much data in the arguments.
I probably never would have found this without the help of this answer and TooLargeTool.

When I am dealing with the WebView in my app it happens. I think it's related to addView and UI resources.
In my app I add some code in WebViewActivity like this below then it runs ok:
#Override
protected void onDestroy() {
if (mWebView != null) {
((ViewGroup) mWebView.getParent()).removeView(mWebView);
mWebView.removeAllViews();
mWebView.destroy();
}
super.onDestroy();
}

I found the root cause of this (we got both "adding window failed" and file descriptor leak as mvds says).
There is a bug in BitmapFactory.decodeFileDescriptor() of Android 4.4.
It only occurs when inPurgeable and inInputShareable of BitmapOptions are set to true. This causes many problem in many places interact with files.
Note that the method is also called from MediaStore.Images.Thumbnails.getThumbnail().
Universal Image Loader is affected by this issue. Picasso and Glide seems to be not affected.

This one line of code in writeToParcel(Parcel dest, int flags) method helped me to get rid of TransactionTooLargeException.
dest=Parcel.obtain();
After this code only i am writing all data to the parcel object i.e dest.writeInt() etc.

Try to use EventBus or ContentProvider like solution.
If you are in the same process(normally all your activities would be), try to use EventBus, cause in process data exchange does NOT need a somewhat buffer, so you do not need to worry about your data is too large. (You can just use method call to pass data indeed, and EventBus hide the ugly things)
Here is the detail:
// one side
startActivity(intentNotTooLarge);
EventBus.getDefault().post(new FooEvent(theHugeData));
// the other side
#Subscribe public void handleData(FooEvent event) { /* get and handle data */ }
If the two sides of Intent are not in the same process, try somewhat ContentProvider.
See TransactionTooLargeException
The Binder transaction failed because it was too large.
During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown.

I got a TransactionTooLargeException from a Stackoverflow error in a Android Espresso test. I found the stackoverflow error stack trace in the logs when I took off the Logcat filter for my app.
I'm guessing that Espresso caused the TransactionTooLargeException when trying to handle a really large exception stacktrace.

Also i was facing this issue for Bitmap data passing from one activity to another but i make a solution by making my data as static data and this is working perfect for me
In activity first :
public static Bitmap bitmap_image;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
bitmap_image=mybitmap;
}
and in second activity :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
Bitmap mybitmap=first.bitmap_image;
}

I have also lived TransactionTooLargeException. Firstly I have worked on understand where it occurs. I know the reason why it occurs. Every of us know because of large content. My problem was like that and I solved. Maybe this solution can be useful for anybody.
I have an app that get content from api. I am getting result from API in first screen and send it to second screen. I can send this content to second screen in successful. After second screen if I want to go third screen this exception occurs. Each of my screen is created from Fragment. I noticed that when I leave from second screen. It saves its bundle content. if this content is too large this exception happens. My solution is after I got content from bundle I clear it.
class SecondFragment : BaseFragment() {
lateinit var myContent: MyContent
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
myContent = arguments?.getParcelable("mycontent")
arguments?.clear()
}

If you converted Bitmap into Base64 in projects and save it to parcelable object you shuold resize bitmap with below code ,
replace png with jpeg and replace quality 100 to 75 or 60 :
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, byteArrayOutputStream)
this solution works for me

sometime Activity include some Fragment when Activityneed to totally recreate Fragments content,
if the sportFragmentManager.fragments without clear history fragments
val fragments = sportFragmentManager.fragments
val transaction = sportFragmentManager.beginTransaction()
for (frag in fragments){
transaction.remove(frag)
}
transaction.commitAllowingStateLoss()
serveral times recreate Fragments the Activity will happen (debug use tooLargeTool)
