NullPointer and ContentView not created. FriendsFragment


Ribbit keeps crashing after I finished this "exercise". After i have chosen a picture to send to friend ( camera-button --> Choose Picture --> Push picture) I get an NullPointer in FriendsFragment from the line "getActivity()setProgressBarIndeterminateVisibility(false);" Tried to fix this by initiating the Activity outside the FindCallback scope, which worked, but unfortunately it resulted in a new error. "IllegalStateException: Content view not yet created ", on the line "ArrayAdapter<String> adapter 0 new ArrayAdapter<String>( etc.. ". I did try to download your code to be sure that is similar, but I still get the same error. What is it that i'm missing?
