There you go:

    Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    @Override
    public void uncaughtException(Thread paramThread, Throwable paramThrowable) {

        new Thread() {
            @Override
            public void run() {
                Looper.prepare();
                Toast.makeText(getActivity(),"Your message", Toast.LENGTH_LONG).show();
                Looper.loop();
            }
        }.start();
        try
        {
            Thread.sleep(4000); // Let the Toast display before app will get shutdown
        }
        catch (InterruptedException e) {    }
        System.exit(2);
    }
});
