title: android youtube: share a youtube video TO my app?
body: <p>The built in YouTube App for tablets has a sharing-option. For example: I watch a video in the YouTube app and click the button to <strong>share</strong>. Bluetooth, Googlemail, and Dropbox appear for me. 
  I wonder how i can <strong>list my app there</strong>? Which intent-filter has my app to have? How do i <strong>get the video url</strong> then?
  Any idea?
  Thanks.</p>
