I am working Text to Speech for Android application. I am getting confusion on finding a method that to be called when Text to Speech was completed. I tried to call the following methods but the finished was doesn't called, Please have a look into the following code and suggest me.
tts= new TextToSpeech(MainActivity.this, new OnInitListener() {
@Override
public void onInit(int status) {
tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
@Override
public void onUtteranceCompleted(final String utteranceId) {
System.out.println("Completed");
runOnUiThread(new Runnable() {
@Override
public void run() {
//UI changes
}
});
}
});
}
});
Please suggest me. I am using API Level 17.
Minimum API level is 12;
And I got the following error in console:

The problem is not in onUtteranceComplete function , its most likely get called, but you're trying to print the output to System.out , please use android.utils.Log("tag", "success") instead and see what happens.
Also You need to set UtteranceID to get onUtteranceComplete to work
before calling tts.speak method. so to sum up:
TextToSpeech tts= new TextToSpeech(MainActivity.this, new OnInitListener() {
@Override
public void onInit(int status) {
tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {
@Override
public void onUtteranceCompleted(final String utteranceId) {
System.out.println("Completed");
runOnUiThread(new Runnable() {
@Override
public void run() {
//UI changes
}
});
}
});
}
});
Map<String,String> ttsParams = new HashMap<String, String>();
ttsParams.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,
MainActivity.this.getPackageName());
mTts.speak(text, TextToSpeech.QUEUE_FLUSH, ttsParams);
And the exception you're getting has nothing to do with the onUtteranceComplete method, if it is because of tts engine most likely you're not requesting to destroy your instance when finishing your activity.
To fix that add
@Override
onDestroy(){
super.onDestroy();
mTts.shutdown(); //mTts is your TextToSpeech Object
}
To your activity class
