title: Android studio: INSTALL_FAILED_CONFLICTING_PROVIDER facebook sdk
body: <p>I'm facing a strange problem with android studio. I have two Android app that uses facebook sdk with same facebook Application for login and share pictures. With new api, it's necessary to declare inside manifest this:</p>
  
  <pre><code>&lt;provider android:authorities="com.facebook.app.FacebookContentProvider[app_id]"
          android:name="com.facebook.FacebookContentProvider"
          android:exported="true"/&gt;
  </code></pre>
  
  <p>Now if one of that app is already installed on device and i try to install the second one, i obtain this error on Android studio:</p>
  
  <pre><code>INSTALL_FAILED_CONFLICTING_PROVIDER
  </code></pre>
  
  <p>It's necessary a problem of facebook provider, that is the only 
      
  element inside my app.
  So, in this way my two apps couldn't be installed at the same time on the same device?
  I would like if there's a way for use same provider and avoid that error.</p>
