Application working on emulator but not working on actual device
<p>I am testing facebook Single-Sign-On application. 
I am using android platform 2.2 and api level 8. I have similarly created emulator with the same configuration. It is working fine in emulator. But when i test it on actual device that is HTC Desire HD ver 2.2 froyo updated. It opens up a dialog with facebook as title and shows loading screen then disappears.</p>

<p>I am unable to understand the reason for such behavior. </p>

<p>Please help me on this.</p>

<p>Regards,</p>
