title: Google Drive GET_CONTENT intent read file
body: <p>I have an app on android that does some file sharing using cloud storages like dropbox. To start sharing I throw <code>android.intent.action.SEND</code>. 
  On the list that is shown I see the Google Drive app (previously installed), so I try sending the file to it - it works ok, the file appears in the Drive list.</p>
  
  <p>Then, on another device I want to read this file. I throw the
  <code>android.intent.action.GET_CONTENT</code> intent, choose Drive and then don't know how to get to file. I receive an Uri something like this: </p>
  
  <pre><code>content://com.google.android.apps.docs.files/exposed_content/6jn9cnzdJbDywpza%2BlW3aA%3D%3D%0A%3BRV%2FaV94o%2FCcW4HGBYArtwOdHqt%2BrsYO4WmHcs6QWSVwp%2FXogkRAgit7prTnfp00a%0A
  </code></pre>
  
  <p>which I don't know how to transform to physical file path. How could I get the file contents from this?</p>
  
  <p>I played around the content provider and can get the file name, but not the full path or anything else.</p>
  
  <p>For the dropbox I get the <code>file://</code> style uri, straight and simple, works well. </p>
