Twitter dialog does not dismiss in android

Hi,

Thanks for this project. But i have an issue. I am trying to sign in with my twitter account but then it doesnot redirect back to the application activity. it however works well with the emulator, and the url generated on the emulator is :

http://oauth/authorize?oauth_token=oauth_token_here&oauth_verifier=oauth_verifier_here

but when i run this on a device the url just shortens to:
https://api.twitter.com/oauth/authorize

Please assist.
Thanks.
