title: Android Webview signout issue
body: <p>In my webview app when I run the app for the first time and log out from a user session, close the app and then when I open the app again instead of asking user credentials I find myself already logged in. I tried clearing cookies but then it always require sign in on every restart. I only want it to ask for sign in when the user logs out from the app.</p>
  
  <p>Please Help!!</p>
  
  <p>Here is a snippet of the code:</p>
  
  <pre><code>  @Override
