title: PendingIntent doesn't send Extra
body: <p>I'm working on an app which with you can create Screenshots of your desktop on your Android Device and while this is working fine, I've got a problem sharing the image from a notification. I'm using almost the same code for sharing from the AppBar and for sharing from the notification but the notification action isn't working. While it opens the Application Chooser how it should, it isn't sending the Image with it.</p>
  
  <p>Here's the relevant code:</p>
  
  <pre><code>Uri lastShotUri; //populated from the MediaScanner
  
  Intent shareIntent = new Intent();
  shareIntent.setAction(Intent.ACTION_SEND);
  shareIntent.putExtra(Intent.EXTRA_STREAM, lastShotUri);
  shareIntent.setType("image/png");
  Intent intent = Intent.createChooser(shareIntent, getResources().getText(R.string.send_to));
  PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(),
      0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
  builder.addAction(R.drawable.ic_share_variant_black_24dp, "Share", pendingIntent);
  </code></pre>
  
  <p>I don't get why it isn't working here but why it is working from the Application itself. If someone knows what I'm doing wrong, I would really appreciate help on this one.</p>
  
  <p>Logcat Output (first one from ActionBar, second from Notification)</p>
