Application crashes after Toast disappears

Question

I have an android application which plays streams from the internet. When there is no stream to play, the app should show a Toast with the message: "Video can't be played" and the screen should be black. When a try these app on a 4.2 Android box everything is alright, but on a 4.4 android box, after the Toast disappears the app crashes. This is the code that shows the Toast:

public void setOnErrorListener(){

        OnErrorListener oel = new OnErrorListener(){

            @Override
            public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
                log.i("TiboVideoView-","error");
                //catchupVideoView.unlockPlayer();

                //Toast.makeText(context,context.getString(R.string.videoerror), Toast.LENGTH_LONG).show();

                nowPlayingDate.setTime(standartTime.getTime());
                nextPlayingDate = null;

                    try {
                        if (isPlaying()) {
                            try {                       
                                stopPlayback(); 
                            } catch (Exception f) {
                            }
                        }
                    } catch (Exception g) {
                    }


                    try{
                    handler.post(LOG_CHANNEL_LOGS);
                    }
                    catch(Exception e)
                    {
                        e.printStackTrace();
                    }

                try
                {
                Toast.makeText(context,context.getString(R.string.videoerror), Toast.LENGTH_LONG).show();
                }
                catch(Exception e)
                {
                    e.printStackTrace();
                }
                return true;
            }

        };

        super.setOnErrorListener(oel);
    }

This is the output from Logcat:

Does anybody understand why is this happening?

Can you post some code please? How many task are you starting? Without the Toast the application crashes? — Atlas91, May 27 '15 at 12:41
I found what the problem was, i shoud put mp.reser OnErrorListener — Maria Agaci, May 28 '15 at 10:04

Try to see this: Avoiding RejectedExecutionException in Android 4.4 when app uses list. I'm just writing the accepted answer:

The problem lies with the different Executors that AsyncTask uses depending on targetSdkVersion of the app:

1) targetSdkVersion <= 12

AsyncTask.execute() uses the AsyncTask.THREAD_POOL_EXECUTOR. The queue in AsyncTask.THREAD_POOL_EXECUTOR is limited to 128 items. If the queue is full RejectedExecutionException is thrown. This is what happens here

2) targetSdkVersion > 12

AsyncTask uses the AsyncTask.SERIAL_EXECUTOR. AsyncTask.SERIAL_EXECUTOR has an unbounded queue. So in this scenario RejectedExecutionException is never thrown.

Solution 1 (AKA the "clean" solution)

Use a separate APK with targetSdkVersion > 12 and a higher versionCode so that is preferred for HONEYCOMB_MR2 and later versions of Android. This will cause AsyncTask to use ThreadPool.SERIAL_EXECUTOR on HONEYCOMB_MR2 and later version of Android.

Solution 2 (AKA the dirty hack)

Just make AsyncTask.SERIAL_EXECUTOR the default using Reflection.

AsyncTask.class.getMethod("setDefaultExecutor", Executor.class).invoke(null, AsyncTask.SERIAL_EXECUTOR);

Of course i need to see your code to understand how solve your problem.

EDIT. Check that context is not null for first.. by the way, can you post the entire AsyncTask please?

This: http://developer.android.com/reference/java/util/concurrent/RejectedExecutionException.html says, "Exception thrown by an Executor when a task cannot be accepted for execution."

Additionally I noticed this: Package has already posted 50 toasts. two times. Is the code supposed to show 100 toasts?

You should show some code, too. An exception is always a little bit cryptic.

In addition to this, I suspect you may be stuck in an infinite loop creating toasts. (Source : personal experience) – SlashG May 27 '15 at 12:45
My bad, clicked to fast, didn't notice I was on the java api. – KJaeg May 27 '15 at 12:50
