Question

So I’ve got an activity in my android app, that runs on start.
This activity is just a page with a start button.
When I press the start button, it calls another activity and closes itself:

Intent i = new Intent(this, Dictating.class);
startActivity(i);
finish();

The other Activity is using Text-to-speech to dictate some words.
Now I’ve got something weird happening:

1) I listen to the dictating.
2) I press back button: dictating stops (what I want)
3) I run again the app, press the start button. Now I have my new activity running and dictating, but in the back I can hear the older Activity that resumed where it was, and continues dictating.

I would like for the new activity to start all over again, and not keep the other activity.
How can I do that ?

PS: This is an activity problem, and not a text-to-speech problem as I’m flushing the text-to-speech each time, It could not be kept in the memory

Thank you

EDIT:

Here is the onCreate of my Dictating class, there is tons of code in this class, I obviously don’t want to post all my code, so here is some parts:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.streaming);

    Intent checkIntent = new Intent();
    checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);

    this.txtCurrentWord = (TextView) findViewById(R.id.txtCurrentWord);
    this.btnPlayPause = findViewById(R.id.btnPlayPause);
    this.btnPlayPause.setOnClickListener(this);

}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == MY_DATA_CHECK_CODE) {
        if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
            // success, create the TTS instance
            this.tts = new TextToSpeech(this, this);
        } else {
            // missing data, install it
            Intent installIntent = new Intent();
            installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);
        }
    }
}

there are a few weird things I’m doing like:

Runnable task = new Runnable() {
    public void run() {
        //runs on ui
        runOnUiThread(new Runnable() {
            public void run() {
                readNextWord();
            }
        });
    }
};
worker.schedule(task, 1, TimeUnit.SECONDS);

this delays the next word by one second, and then executes a fonction in the main ui thread. not sure if this matter

And some flushing at the end:

@Override
public void onDestroy() {
    tts.shutdown();
    super.onDestroy();
}

You need to add launchMode property to your activity inside AndroidManifest file, for more detail see “Using the manifest file”
