title: TextToSpeech : deprecated speak function in API Level 21
body: <p>I try to use a TextToSpeech in my app,</p>
  
  <pre><code>String text = editText.getText().toString();
  tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
  </code></pre>
  
  <p>But the function speak(String text, int queueMode, HashMap params)  is deprecated in API Level 21. Instead of that, it is adviced to use speak(CharSequence text, int queueMode, Bundle params, String utteranceId). 
  But I don't know how to set it. Thanks</p>
