Android: Coordinate SounPool and TTS

Question

I define this simple method in my Activity:

private void playSound(final boolean ttsOn) {
    // TODO Auto-generated method stub
    int water = 0;      
    SoundPool pl;
    pl = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);

    water = pl.load(this, R.raw.water_boiling, 0);

    pl.setOnLoadCompleteListener(new OnLoadCompleteListener() {

        @Override
        public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
            // TODO Auto-generated method stub
            soundPool.play(sampleId, 1f, 1f, 0, 0, 1);
            if(ttsOn)
                speakOut();
        }
    });

Where speakOut() is this:

private void speakOut() {

    tts.setLanguage(Locale.ITALIAN);
    tts.speak(n.Message, TextToSpeech.QUEUE_FLUSH, null);
} 

But this reproduce my mp3 file and my tts speak at same time.

So the question is:

How can I reproduce tts after my mp3?

Answer 1

I solve the problem in this way:

private void playSound(final boolean ttsOn) {
    // TODO Auto-generated method stub
    int water = 0;      
    SoundPool pl;
    pl = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);

    water = pl.load(this, R.raw.system_alert_003, 0);



    pl.setOnLoadCompleteListener(new OnLoadCompleteListener() {

        @Override
        public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
            // TODO Auto-generated method stub
            soundPool.play(sampleId, 1f, 1f, 0, 0, 1);
            if(ttsOn)
            {
                myMediaTimer = new Timer();
                myMediaTimer.schedule(new TimerTask() {         
                    @Override
                    public void run() {
                        speakOut();
                    }

                }, DURATION_MEDIA_FILE);

            }
        }
    });


    Log.i("onCrete","WATER FILE: "+water);

}

Even if this require the knowledge of duration of mp3 file.
