title: How to log into Facebook without the Facebook app?
body: <p>I use a Facebook sample app (<code>SessionLoginSample</code>) to understand how to log into Facebook. My Facebook SDK is latest — <a href="http://developers.facebook.com/docs/reference/android/3.0" rel="nofollow noreferrer">version 3.0</a>. When I have the Facebook app installed, I can log in without any problems.</p>
  
  <p>The problem is when I uninstall my Facebook app and re-install the sample (so it doesn't log in automatically). I try to log in but I can see only a white empty dialog. The only option I have is to close it. Even if I wait 10-15 minutes, the dialog doesn't change.</p>

  <p>I tried to debug the Facebook SDK but I couldn't find what's causing the error.</p>
  
  <p>I tested this on LG-E610 (4.0.3) and HTC Sensation (4.0.3).</p>
  
  <p>Is this facebook sdk error or I'm doing something wrong?</p>
  
  <p><strong>Edit:</strong> I tested this issue again 10 days later in the same coditions and everything seems to work  as expected. </p>
