title: How to open new activity after login success - android app
body: <p>My friend and I are trying to login via facebook. We took code from facebook developer page:
  <a href="https://developers.facebook.com/docs/android/login-with-facebook" rel="nofollow">https://developers.facebook.com/docs/android/login-with-facebook</a></p>
  
  <p>The problem is how to call another activity right after authorization succeed and remove logout button. We've been reading other posts but there is no solution that helped us.</p>
