FBConnect Android Error : OAuthException while uploading image to Facebook

I have implemented the facebook connect with android. It was working fine before but today i got this error.

{"error":{"type":"OAuthException","message":"(#1) An unknown error occurred"}}

I am unable to figure this out. Does anyone faced the same error before?
