To fix it you need save instance of your Fragments. To do this you need just override onSaveInstanceState method for your Fragment.
@Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString(BundleKeys.MESSAGE, message); }
Also you need restore fragment state in onCreateView of onActivityCreated methods
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (savedInstanceState != null) { if (!savedInstanceState.isEmpty()) { Loger.i(TAG, "!savedInstanceState.isEmpty()"); if (message == null) { message = new Gson().fromJson(savedInstanceState.getString(BundleKeys.MESSAGE), Message.class); } } } }
Hope it help you.
