POAndroid TTS + WakeLock
text
Body
copied!<p>I have an app which is using TTS to read text in an AsyncTask. My problem is when the phone goes to sleep the playback stops. I went through many threads in the topic and everything points towards WakeLock. However I am not able to implement it, no matter if I call it in the activity class or the AsyncTask class. I use the following code:</p> <pre><code>PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My wakelook"); wakeLock.acquire(1000); </code></pre> <p>I guess the problem is with TTS, but currently I am clueless. Maybe someone with more TTS and WakeLock experience could help me out.</p> <h2>Thanks in advance</h2> <p>EDIT:</p> <p>Here is the full code (unimportant parts removed):</p> <pre><code> public class PlayerActivity extends Activity implements TextToSpeech.OnInitListener { // TTS fields private TextToSpeech mTts; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.player); List<TTSPlayItem> playItems = new ArrayList<TTSPlayItem>(); TTSPlayItem playItem = new TTSPlayItem(); playItem.locale = getLocale1(); playItem.text = getText1(); playItem.position = position; playItems.add(playItem); playItem = new TTSPlayItem(); playItem.locale = getLocale2(); playItem.text = getText2(); playItem.position = position; playItems.add(playItem); TTSPlayItem[] passPlayItems = playItems .toArray(new TTSPlayItem[playItems.size()]); TTSAsyncTask speak = new TTSAsyncTask(); speak.execute(passPlayItems); } /* * AsyncTask for TTS */ private class TTSAsyncTask extends AsyncTask<TTSPlayItem, TTSPlayItem, String> { // WakeLock PowerManager pm; PowerManager.WakeLock wakeLock; protected void onPreExecute() { } @Override protected String doInBackground(TTSPlayItem... items) { pm = (PowerManager) getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My wakelook"); wakeLock.acquire(); for (int i = 0; i < items.length; i++) { TTSPlayItem[] progressList = new TTSPlayItem[1]; progressList[0] = items[i]; publishProgress(progressList); Log.i(TAG, "Play - locale: " + items[i].locale.toString() + ", text: " + items[i].text); int treshold = 0; while (true) { int result = mTts.setLanguage(items[i].locale); Log.i(TAG, "Locale return: " + result); if (result == 1) break; if (treshold == 100) break; treshold++; } mTts.speak(items[i].text, TextToSpeech.QUEUE_FLUSH, null); while (mTts.isSpeaking()) { if (playing == false) { mTts.stop(); return "Playback stopped."; } } // wait android.os.SystemClock.sleep(1000); } playing = false; if (wakeLock.isHeld()) wakeLock.release(); return "Played list of " + items.length + " items."; } protected void onProgressUpdate(TTSPlayItem... result) { } protected void onPostExecute(String result) { } /* * TTS methods */ public 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); } } } public void shutdownTTS() { playing = false; // Don't forget to shutdown! if (mTts != null) { mTts.stop(); mTts.shutdown(); } } @Override public void onDestroy() { shutdownTTS(); super.onDestroy(); } public void onStop() { shutdownTTS(); super.onStop(); } public void onPause() { shutdownTTS(); super.onPause(); } } </code></pre>
