title: Android media player fails MP3 with PVMFErrNotSupported?
body: <p>I have a downloaded MP3 that I can verify as MP3 by adb pull to my mac or pc and play in its respective media player.  However, the error from Android implies that it does not support the format.  I think it may be related to the directory location where I am storing the file, but that does not make sense (/data/data/com.myapp/files/file_audio.mp3).  This is the code inside an AsyncTask:</p>
  
  <pre><code>    protected String doInBackground(String... params) {
  
          String filename = params[0];
  
          try {
              StringBuilder filenameMp3 = new StringBuilder().append(context.getFilesDir());
              filenameMp3.append("/").append(filename);
  
              Uri uriMp3 = Uri.parse(filenameMp3.toString());
              Log.d(TAG, "Listen to this ringtone! [" + uriMp3.toString() + "]");
  
              MediaPlayer mp = MediaPlayer.create(context, uriMp3);
              mp.prepare();
              mp.start();
          } catch (IllegalStateException e) {
              Log.e(TAG, e.toString());
              e.printStackTrace();
          } catch (IOException e) {
              Log.e(TAG, e.toString());
              e.printStackTrace();
          }
  
          return null;
      }
