I have a% & $ 5 # ~ € problem connecting to twitter. (Code below)
Firstly, everything is set up for me (twitter keys, manifest callback, etc.), then I call twitter and open the browser, and then I log in to Twitter and accept the application, then the browser returns to the application and try to get reply from Twitter, but I get NULL as the answer.
Can someone help me find what is happening with this?

PD: I follow this guide: http://www.androidhive.info/2012/09/android-twitter-oauth-connect-tutorial/
PD 2: Some people think that the problem is the date and time of the phone ( https://dev.twitter.com/discussions/374 ), but I changed it and it doesn’t work
