title: Android unreliable behavior of mediaplayer class
body: <p>I have coded a simple app with a sound on button klick. On the emulator there indeed is a error: "<strong>34 mp3extractor unable to resync. signalling end of stream</strong>" 
  But the sound has happened. I could hear it.</p>
  
  <p>The problem is, <strong>on some real devices the sound doesn't work first or second try after installing</strong>. On a lot of devices the sound happens only from the second or third try. </p>
  
  <p>That behavior is very unreliable and inconsistent.</p>
  
  <p>Does anybody knows that problem? Thank you for your answers. 
  This is my code:</p>
  
  <p>Button.OnClickListener Button_Auswertung_OnClickListener =
             new Button.OnClickListener() {          </p>
  
  <pre><code>        public void onClick(View v) {           
  
          MediaPlayer mepl = MediaPlayer.create(Activity.this,  R.raw.sound);  
          mepl.start();
  
          Toast.makeText(getApplicationContext(), "klicked", Toast.LENGTH_SHORT).show();             
  
        }
  </code></pre>
  
  <p>};</p>
