Android not acknowledging TTS Engine

Question

I am developing a very simple app in here. It\'s for my Cerebral Palsy daughter. It\'s just a big YES and NO buttons, so she can press them when requested.

Well... I am

Answer 1

This is what I have in onActivityResult(...)

@Override
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
            mTts = new TextToSpeech(this, this);
        } else {
            // missing data, install it
            Intent installIntent = new Intent();
            installIntent.setAction(
                TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);
        }
*/
        if (mTts==null) {
            Intent installIntent = new Intent();
            installIntent.setAction(
                TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);                           
        }
        mTts = new TextToSpeech(this, this);                
    }
}

Instead of using if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {...}, I check if mTts has already been instantiated. You'll also have to set mTts as static, as was mentioned by jlquant and Rakesh in an earlier post, so you'll have only a single instance of it. For example, private static TextToSpeech mTts.

So, unless you "Force stop" the app or it stops working because of an error, it won't anymore call the startActivity(installIntent);-- the annoying culprit that asks you to install TTS every time.
