title: AndroidsetAudioSource failed
body: <p>I tried <a href="http://developer.android.com/guide/topics/media/audio-capture.html" rel="nofollow">this example</a> to record audio from the microphone.
  When I start recording <code>java.lang.RuntimeException: setAudioSource failed</code> always appears. 
  I also add this permissions to the <code>AndroidManifest.xml</code>:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.RECORD_AUDIO" /&gt;
  &lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/&gt;
  </code></pre>
