title: Android: Intent.EXTRA_ALLOW_MULTIPLE allows only single picking
body: <p>I want to open multiple images from the Android gallery using "Intent.EXTRA_ALLOW_MULTIPLE" intent filter:</p>
  
  <pre><code>if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.JELLY_BEAN_MR2) {
      final Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
      intent.setType("image/*");
      intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
      intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
      startActivityForResult(Intent.createChooser(intent, "Add images"), SELECT_MULTIPLE_IMAGES);
  }
  </code></pre>
  
  <p>But whatever app I use (native gallery, QuickPic app), I can only select one single picture. The test device is running Android 5.1.</p>
  
  <p>How can I pick multiple images?</p>
