You don't need to use the ACTION_CHECK_TTS_DATA. Instead use isLanguageAvailable like this: (make sure to call this only after onInit is complete)

    // check if language is available
    switch (tts.isLanguageAvailable(locale))
    {
        case TextToSpeech.LANG_AVAILABLE:
        case TextToSpeech.LANG_COUNTRY_AVAILABLE:
        case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE:
            Log.d(TAG, "SUPPORTED");
            break;
        case TextToSpeech.LANG_MISSING_DATA:
            Log.d(TAG, "MISSING_DATA");//launch the install data activity
            break;
        case TextToSpeech.LANG_NOT_SUPPORTED:
            Log.d(TAG, "NOT SUPPORTED");//report failure
            break;
    }
