title: MediaMetadataRetriever returns null on S3
body: <p>I have the problem that MediaMetadataRetriever always returns null for the title, but only on stock S3. It's working with CyanogenMod on S3 but not with Samsungs stock rom. Also, on my OnePlus is everything working fine.</p>
  
  <p>The Code is very simple:</p>
  
  <pre><code>MediaMetadataRetriever mmr = new MediaMetadataRetriever();
  String titlename = fields[count].getName();
  final Uri uri = Uri.parse("android.resource://" + getPackageName() + "/raw/" + titlename);
  mmr.setDataSource(MainActivity.this, uri);
  final String name = mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_TITLE);
  
  [...]
  
  tv.setText(name + " ");
  </code></pre>
  
  <p>The TextView will show null on Samsung stock ROM, but not on other ROMs.
  This is a bit strange, does someone here have an idea? If not, I'll try a third-party library for ID3 tags.</p>
