Your OOM error is related to the Images you are loading as I am seeing in your log trace.
See this for loading large Bitmaps more efficiently:
A 400 KB image file can easily take up 5-10 MB of RAM.
For requesting to incraese heap size dynamically, Use android:largeHeap="true"
in the manifest.xml.
or/and just use the proper function to decode...

I would check the size of all your images referred to in your ImageViews. If they are large, maybe encode them as different image types to reduce the image size. The Android system is periodically running out of memory and crashing your application currently. It makes sense that you are getting this only sometimes as it depends on how much memory is currently being used for other applications etc... . If you reduce the size of your images significantly you should be able to resolve this.

Increase the gradle.properties in the root of your project :
org.gradle.jvmargs=-XX:MaxHeapSize\=512m -Xmx512m
the default jvmargs is 256
you can request to use more by using.
android:largeHeap="true"
in the manifest.xml.

Android how to open a popup window in an onclick function

In android I am trying to open a popup window to get some user input but the code fails in Activity.java on
if (activity == null && children == null && fragments == null && loaders == null
&& mVoiceInteractor == null) {
return null;
}
Here are the xml files of the layout with the button to open the popup window and the xml of the popup window

and the code for the onclick function is
public void enter_lat_dec_deg(View v) {
layout3 = inflater.inflate(R.layout.manually_enter_numbers, (ViewGroup) findViewById(R.id.manually_entry));
enter_manual_dec_deg = new PopupWindow(layout3 , 700,900,true); // width, height
layout3.post(new Runnable() {
public void run() {
enter_manual_dec_deg.showAtLocation(layout3, Gravity.CENTER, 0, 200);
}
});
input = (EditText) findViewById(R.id.enter_decimal_number);
decimal_input = Float.valueOf(input.getText().toString());
Toast.makeText(GPSTest.this, "this is the decimal input !!!" + decimal_input,
Toast.LENGTH_LONG).show();
}
I have another popup window in the same app that works fine but the same code does not work here.
I am quite new to android programming have probably made a quite obvious mistake but I have done lots of googling and found nothing to fix the problem so any advice would be eagerly anticipated.
Please ask if you would like me to post more code.
The android studio event log has :

David, Hello its yourself here. This is a design fault. Please redesign your app to use activities instead of popups. Have a nice day.

I'm trying to scroll to a particular portion of my TableLayout using scrollTo()

I have a TableLayout within ScrollView:
ScrollView helpSV;
TableLayout myTL;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_help);
helpSV = (ScrollView) findViewById(R.id.helpScrollView);
myTL = (TableLayout) findViewById(R.id.myTableLayout);
}
Also, on clicking a button, a function is made to run:
<Button
android:id="#+id/regButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/button"
android:gravity="left|center_vertical"
android:onClick="register"
android:paddingLeft="20dp"
android:text="Registration"
android:textColor="#fff" />
register() function is as follows:
public void register(View view) {
int index = 5;
final View child = myTL.getChildAt(index);
new Handler().post(new Runnable() {
#Override
public void run() {
helpSV.smoothScrollTo(0, child.getBottom());
}
});
}
For some reason, my app force closes on clicking the button. I've been at this for hours, referred to similar questions but nothing helped so far..
Help? Thanks in advance...

If anybody gets this problem, its probably cos you have made a re-declaration of some variable accidentally.
That's what caused the error in my program..silly me

I'd say you're crashing because View child is null. getChildAt() only gets the visible children, so you shouyld use getChildCount() and getFirstVisiblePosition() to check what is the index of the first visible child and the index of the last visible child by adding count and first visible position.
Also, you could scroll using smoothScrollToPosition() to get directly to the child of interest.

Toolbar null when restore from background

So I recently updated this app to API 21, and consequentially I changed all my ActionBar to Toolbar.
I include the toolbar into the fragment layout using tag, and I set it up in onResume() method. All is working fine when I launch the app, and when I put it in background and immediately restore it (or in a couple of minutes), but if I let it in background for a little, and maybe use some other app, when I restore it, I've a crash. The crash happen in the second line of the setupToolbar() method, surely because the toolbar object is null. My problem is to understand why this object is null, because when I restore the app, the execution flow have to execute onCreateView() first, and then onResume (and so setupToolbar). So the toolbar have to be inflated in the layout.
This is my toolbar layout that's included in fragment_home:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent" android:layout_height="match_parent"
android:layout_gravity="center">

and this is setupToolbar method:
private void setupToolbar() {
Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbarHome);
ImageView ivSearch = (ImageView) toolbar.findViewById(R.id.ivSearchIconActionbar);
ImageView ivMenu = (ImageView) toolbar.findViewById(R.id.ivActionbarOpenDrawer);
ivSearch.setOnClickListener(onSearchClick);
ivMenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
((MainActivity) getActivity()).openOrCloseDrawer();
}
});
}
