title: Always open android webview Login dialog when user logged out from my app
body: <p><img src="https://i.stack.imgur.com/z8Hh6.png" alt="enter image description here"></p>
  
  <p>I've integrated Facebook in my app and the user can login, share and post things.   I've implemented a logout also.</p>
  
  <p>Here is my problem: when user wants to log in, the Facebook SDK checks whether the native app is present or not. </p>
  
  <ul>
  <li>If the native Facebook app is not installed in the user's device then it will open a webview dialog like the image below (First image).</li>
  <li>If the user has the Facebook app, then my app directly asks him/her for permissions without opening the loginUI (Second Image)</li>
  </ul>

  <p>I want to show the Facebook loginUI always.<br>
  Each time the user wants to login.</p>
  
  <p>Please help me.</p>
