App Inventor Thread terminate is not working properly

[Working_Hard]

I am trying to create a thread program which will keep on playing two sound in 1 second interval. When back button is pressed the app will close and the sounds will stop.

Initially when I was pressing back button the app was closing but the sound did not stop hence overridden the method onBackPressed and put thread.terminate method in onBackPressed method. That caused sound to stop but after app was closed error message is popping up. Screenshot of the error is given elow

Below is the code. I have placed try-catch and Log.v in every position but no error received in the log. But found below error, not sure from where this error is coming as this is not associated to any log tag. Below is the error details

To start with, using Log statements is an inefficient way to debug your app. Run the app in debug mode, and use breakpoints to verify code execution.

Memory problems can occur with MediaPlayer if you don't call release() after calling stop(). Try that.

If you Google the exception you're getting -

Caused by: com.google.android.apps.gsa.shared.exception.GsaIOException: Error code: 393238 | Buffer overflow, no available space.

it also turns up some useful links, like this:

I have used mp.stop and mp.release in onBackPressed, onPause etc. But I still am getting same error message.

Modified code is given below.

@Override
    public void onBackPressed() {
        if (myThread!=null)
        {
            try {
                mp.stop();
                mp.release();
                iTerminate = 0;
                myThread.interrupt();
                //myThread.stop();
                myThread = null;
            }
            catch (Exception ex) {
                Log.v("ThreadStopLog",ex.getMessage());
            }
        }
        super.onBackPressed();
    }

In logcat I am getting below error

Also the link given above seems not related to my issue.

Also forgot to mention I have already tried to debug it. But still could not get any error.
