context.getActivity() returns null in fragment after fragment is resumed

Question

When fragment is running, context.getActivity() is not null but when it turns to onPause() method and resumed back then context.getActivity() method returns null.

@Override public View onCreateView(LayoutInflater inflater, 
                                   ViewGroup container, 
                                   Bundle savedInstanceState) {
  view = inflater.inflate(R.layout.levelmission, container, false); 
  initComponents(view); 
  return view; 
}

And indicate whether you use the support lib or not, and which version. — Snicolas, Dec 06 '13 at 11:41
It might be null because the Fragment isn't attached to the Activity yet. — Ahmad, Dec 06 '13 at 11:44
@jimpanzer LoadMissionCallback mission = new HexPress_LevelMissions(); Here HexPress_LevelMissions() is Fragment and LoadMissionCallback is an interface. — Muhammad, Dec 06 '13 at 12:07
Here i have attached it: @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { view = inflater.inflate(R.layout.levelmission, container, false); initComponents(view); return view; } — Muhammad, Dec 06 '13 at 12:27

If you use

setRetainInstance(true);

you should reset your activity each time you recreate your view so something like :

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

 view = inflater.inflate(R.layout.levelmission, container, false); 
 initComponents(view); 
 mActivity = getActivity();

 return view; 
}

then use mActivity instead of context.getActivity();

Using `setRetainInstance(true)` is like setting the `android:configChanges` property to deal with configuration changes. Using it for this purpose is a hack more than a solution. – Alex Lockwood Apr 16 '14 at 04:13
