How to properly handle RejectedExecutionException for AsyncTasks? - android

I currently have a BaseAdapter that is populating a gallery of thumbnails. When an item is visible, an AsyncTask is started from the adapters getView() method to download the thumbnail and when completed the imageview is updated with the correct bitmap. This seems to work really well, except when the user scrolls really fast. This is because of the AsyncTask limitations of holding 128 threads in the queue at any given time.
So my question is how do I properly detect whether the thread pool is full before scheduling another task? Or how do I properly catch the error so I don't receive a force close?
Here are the errors I'm receiving:

You can go through documentation of AsyncTask:
http://developer.android.com/reference/android/os/AsyncTask.html
And you can use getStatus() of AsyncTask to know the status of the worker thread. See http://developer.android.com/reference/android/os/AsyncTask.html#getStatus%28%29

I ended up using this as a template. It works by creating a worker thread and adding images to it's queue.

They have fixed the issue in Android 6.0.1. Just update your Android OS version and it will be ok.

I don't know what "java.lang.IllegalStateException: No AppStateClient. Did you request it at setup?" means for. Thanks.
You need to add the APPSTATE client as shown below:
//should be called on your application start
//best practice to call it only once. Any way other calls will be ignored by the plugin.
//if you want to use only Game service (Leader-boards, achievements) use GooglePlayConnection.CLIENT_GAMES
//if you want to use only Google Cloud service use GooglePlayConnection.CLIENT_APPSTATE
//if you want both: GooglePlayConnection.CLIENT_GAMES | GooglePlayConnection.CLIENT_APPSTATE
//and if you whant to get avaliable permissions for your app use: GooglePlayConnection.CLIENT_ALL
GooglePlayConnection.instance.start (GooglePlayConnection.CLIENT_GAMES | GooglePlayConnection.CLIENT_APPSTATE );

What sort of xml is the SimpleCursorAdapter expecting?

I've been having problems with displaying Contacts in an AlertDialog, and I think I've found the
problem, but am still confused. The pertinent suspect part of my code is:
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_1, mContacts,
new String[] { ContactsContract.Contacts.DISPLAY_NAME },
new int[] { android.R.id.text1 });
...Now "simple_list_item_1" is accepted by the compiler (the app runs in the Emulator), however when
I try to run this ListActivity, it bombs.
So after reading elsewhere about how to accomplish this task my eyes lit upon the aforepasted
"simple_list_item_1" - where is that? I didn't create any simple_list_item_1.xml file, and it doesn't exist in my \res\layout folder. So I (in Eclipse) right-clicked "simple_list_item_1" and selected "Open Declaration" and it invoked an err msg much or exactly like the one I see in the Debug Perspective about "Class File Editor | Source nout found | The JAR file ....\android.jar has no source attachment."
So...assuming this is the problem (there is no "simple_list_item_1.xml" in my \res\layout folder), what exactly is expected in this file (which I assume is simply a xml definition of what I want each Contact to display in)?
==============
Here is some LogCat data:
Here are the last lines in LogCat (it seems to die/hang once it gets to the ListActivity (ContactsActivity):

simple_list_item_1 is a standard layout defined in the SDK, it's basically just a TextView with the id "android:id/text1", which is what you supply in your view identifiers.
Do you have the stacktrace of the crash? Because it's most likely not due to a missing simple_list_item_1 layout.
Create a new XML layout file using Eclipse wizard. The name of this file will replace simple_list_item_1 in your code:
In this layout, create a TextView (or any other container) element and call it text1:
Then SimpleCursorAdaptor will match your contact info and the text1 field in your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />

Restlet can't get the data with Android

I'm going to get data with Restlet of this official OData page:
http://services.odata.org/OData/OData.svc/
I've started this tutorial:
http://weblogs.asp.net/uruit/archive/2011/09/13/accessing-odata-from-android-using-restlet.aspx
My problem is, that at the end, he can't get the metadata. But first:
When I'm trying to generate the Restleg-Files (Point 5), the console is showing this, where the lines with are date are red:

The source code has been generated in directory: C:\Projects\MyProjects\Android App\main\app\Java\Workspace\TestOData2\src
So the files are generated, but when I'm going forward in the tutorial, copy the class into my Android project, import libraries and write the following code, then I get the error below.
public ArrayList<Product> getOdataSampleProduct(String zip) {
ODataDemoService proxy = new OdataDemoService();
try {
Query<Product> query = proxy.createProductQuery("Products(1)");
Product product = query.iterator().next(); //breaks here
Log.d("Test","id: "+product.getId()); //isn't logged
}
catch(Exception e) {
//is catched before query.iterator().next()
};
So, LogCat shows this error (line 3 is red):

It seems that there is a problem with the metadata, but I can't figure out what.
Any idea?
Could you try registering the Restlet extension for Apache HTTP Client instead of the default internal connector?
See this page for details:
http://wiki.restlet.org/docs_2.1/13-restlet/275-restlet/266-restlet.html
At least, I've found a solution:
I had to put the query into an AsyncTask.
Before, in the UI thread, the query didn't have time to get an answer.
So I put it into the doInBackground.

Android Hello World app crashes: IllegalArgumentException from Surface.lockCanvasNative

I am trying to run the simplest Hello World example app and looks like I can crash it even all it does is showing a TextView.
Steps to reproduce: Launch it in the emulator (1.5). Open the app - it shows the text view, then lock the phone by pressing "end call" button. Unlock by pressing "menu", then press "back". App crashes with "The process android.process.acore has stopped unexpectedly..." and Force Close button. It does not happen all the time, but I am able to reproduce it every time after wiping the user data at least.
I wonder if default Hello World is missing a detail which was considered too advanced for a hello world... Such problems with a basic example does not look very encouraging =)
Any idea what detail is missing and how to avoid this crash?

sounds to me more like something wrong with your emulator. Why dont you delete your emulator and create a new one and try again with a fresh project.
Hope that will help you. BTW why are you using emulator on 1.5?? Start to build applications for min 2.1.
Good luck.
