Answer 1

You try to show a Toast in a thread that is not the UI(main) thread. You should change this

@Override
public void onUtteranceCompleted(String utteranceId) {
    Log.i("CALLBACK", utteranceId); //utteranceId == "SOME MESSAGE"
    Toast.makeText(getApplicationContext(),"Call     Back",Toast.LENGTH_LONG).show();// I Cannot Toast here. Or do something more than Log
}

into this

@Override
public void onUtteranceCompleted(String utteranceId) {
    Log.i("CALLBACK", utteranceId); //utteranceId == "SOME MESSAGE"

    runOnUiThread(new Runnable() {

        public void run() {
            Toast.makeText(getApplicationContext(),"Call Back",Toast.LENGTH_LONG).show();
        }
    });
}

That way your code is dispatched to the main thread where you are allowed to show Toasts
