Android Twitter Received Authentication Challenge Is Null

I am using Twitter android integration. I already successfully share text on twitter from android app. But now my code is not working. I checked following demos : http://www.andro

I solved it but still confuse what is the reason why Twitter not worked. I solved it by running project in different device and It works. Strange!

If somebody facing problem in Twitter then you need also test in different devices.
