Speak failed not bound to TTS Engine

Following this Method...... private TextToSpeech tts; tts = new TextToSpeech(this, this);  public void onInit(int status) {         // TODO Auto-generated method stub         if (status == TextToSpeech.SUCCESS) {             int result = tts.setLanguage(Locale.US);             //tts.setPitch(0.5f); // set pitch level             tts.setSpeechRate(1); // set speech speed rate             if (result == TextToSpeech.LANG_MISSING_DATA                     || result == TextToSpeech.LANG_NOT_SUPPORTED) {                 Log.e("TTS", "Language is not supported");             }             else {                 speakOut();             }         } else {             Log.e("TTS", "Initilization Failed");         }     }     @Override     public void onDestroy() {         // Don't forget to shutdown!         if (tts != null) {             tts.stop();             tts.shutdown();         }         super.onDestroy();     }     private void speakOut() {         tts.speak(traintime, TextToSpeech.QUEUE_ADD, null);         tts.speak(bustime, TextToSpeech.QUEUE_ADD, null);     } I would suggest adding some logging into your code to see where it is failing. Firstly, try putting tts = null; after tts.shutdown(); in onDestroy() If that doesn't work, check the status onInit. At the moment your code handles success, but you appear to do nothing if you get a fail message message. Put logging in the OnStart and OnInit to check you are correctly calling them - it may be an error somewhere in your code that you are not detailing above.
