title: application/vnd.android.package-archive not showing apk files in android 4.1
body: <p>"application/vnd.android.package-archive" mime type not showing apk files in File manager.</p>
  
  <p>In my chatting app , I want to show only apk files in File manager to select one of them to send it to another user. I used the mime type "application/vnd.android.package-archive" in the intent.
  That worked fine in my device Galaxy j5 "android 6.0", but when i try in my another device Galaxy core one "android 4.1" , all folders in my File manager are empty and not showing any file with any type.</p>
  
  <pre><code>public void openFile(String mimeType) {
  
      Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
      intent.setType(mimeType);
      intent.addCategory(Intent.CATEGORY_OPENABLE);
  
      // special intent for Samsung file manager
      Intent sIntent = newIntent("com.sec.android.app.myfiles.PICK_DATA");
      // if you want any file type, you can skip next line
      sIntent.putExtra("CONTENT_TYPE", mimeType);
      sIntent.addCategory(Intent.CATEGORY_DEFAULT);
  
      Intent chooserIntent;
      if (getActivity().getPackageManager().resolveActivity(sIntent, 0) != null){
          // it is device with Samsung file manager
          chooserIntent = Intent.createChooser(sIntent, "Open file");
          chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] { intent});
      } else {
          Toast.makeText(getActivity() , "not samsung" , Toast.LENGTH_SHORT).show();
          chooserIntent = Intent.createChooser(intent, "Open file");
      }
  
      try {
          startActivityForResult(chooserIntent, REQUEST_CODE_APK_FILE);
      } catch (ActivityNotFoundException ex) {
          Toast.makeText(getActivity(), "No suitable File Manager was found.", Toast.LENGTH_SHORT).show();
      }
  }
  </code></pre>
  
  <p>In android 6.0 all worked fine, but in android 4.1 File manager is empty of files.</p>
