oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: null about oauth-signpost HOT 5 OPEN

I was having the same problem on Ice Cream Sandwich.
Turns out, you can't access the network on the IU Thread anymore (by default 
with the new StrictMode).
I put the code in AsyncTask and it's now working on my Galaxy Nexus ;)

I can confirm that the above solution works.

I was already doing this call in a thread (ASyncTask) and I still get the error 
on the Asus Transformer Prime. Would appreciate someone looking in to this. As 
a note this ONLY happens on Android 4.0

I can confirm that using AsyncTask fixed the issue for me on all Android 
devices running Android 4.0 and higher (including the Asus Transformer Prime).

Here is my source code if you want to check it out:

Could anyone help me? I am all new to Android... This is fir my final project 
at University... after sweating a lot I made it work in android 2.33 but now in 
4.2... i get this error.

Any good documentation or blog post about asyncTasks as well? I have no idea 
about how to make them work... as you can see in the code (...)

The idea is, after clicking the button, it takes you to twitter authorization 
area and it comes back once you finished...

Thank you in advance for your possible help
