title: Correct intent to show only Audio files
body: <p>I am trying to pick <code>Audio</code> from Gallery. I am using the following intent.</p>
  
  <pre><code>private void selectAudioFromGallery() {
          Intent intent = new Intent();
          intent.setAction(Intent.ACTION_GET_CONTENT);
          intent.setType("audio/3gp, audio/AMR, audio/mp3");
          startActivityForResult(Intent.createChooser(intent, getString(R.string.select_audio_file_title)), REQ_CODE_PICK_SOUNDFILE);
  
      }
  </code></pre>
  
  <p>I want to select files of type <code>3gp, AMR, mp3</code> and only these files should be listed in the file chooser but the problem I am facing it, it also shows the other files too like text files, image etc.</p>
