We finished by adding to activity: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(null); } It suppresses any saved data on create/recreate cycle of an Activity and avoids fragments auto re-creation.
the new version of android studio uses 2 xml files for each layout. One (e.g. content_main.xml) embedded in the other one (Activity_main.xml). you should open the content_*.xml and do the design in it. hope it helps.

So, first things first: you need to determine if you want to use Instrumental or simple JUnit tests. The difference between them beautifully described by S.D. here; … Read more
Now ActionBarActivity is deprecated so You need to cast your activity from getActivity() to AppCompatActivity first.

I had the same problem and think it happens when you inflate the layout in the Fragment’s onCreateView with null, like you did here: mRootView = (ViewGroup) inflater.inflate(R.layout.list_content, null); Instead you have to do this: mRootView = (ViewGroup) inflater.inflate(R.layout.list_content,container, false); Where container is the Viewgroup.
