In my Android application I am getting a very strange crash, when I press a button (Image) on my UI the entire application freezes and after a couple of seconds I getthe dreaded force close dialog appearing.

Here is what gets printed in the log:

WARN/WindowManager(88): Key dispatching timed out sending to package name/Activity

This is the code for the Button (Image):

findViewById(R.id.endcallimage).setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {
                        mNotificationManager.cancel(2);

                        Log.d("Handler", "Endcallimage pressed");

                        if(callConnected)
                        elapsedTimeBeforePause = SystemClock.elapsedRealtime() - stopWatch.getBase();

                        try {
                            serviceBinder.endCall(lineId);
                        } catch (RemoteException e) {
                            e.printStackTrace();
                        } 
                            dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.FLAG_SOFT_KEYBOARD));
                            dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK));
                    }
            });     

If I comment the following out the pressing of the button (image) doesn't cause the crash:

try {
      serviceBinder.endCall(lineId);
    } catch (RemoteException e) {
      e.printStackTrace();
    } 

The above code calls down through several levels of the app and into the native layer (NDK), could the call passing through several objects be leading to the force close? It seems unlikely as several other buttons do the same without issue.

How about the native layer? Could some code I've built with the NDK be causing the issue?

Any other ideas as to what the cause of the issue might be?
