Saving fragments on rotation when using an Async Task

Saving fragments on rotation when using an Async Task

The question pretty much sums it up, I am trying to save my fragments so
when I rotate the screen the application does not crash but I am not sure
where or how to save my fragments, I have tried using a fragment manager
and setting retainstate to true as well as checking the saved instance
state.
This is my code : EventsActivty - Hosts the fragments
@Override
public void onCreate(Bundle savedInstanceState) {
new AsyncLogin().execute(username, password);
super.onCreate(savedInstanceState);
username = getIntent().getStringExtra("username");
password = getIntent().getStringExtra("password");
}
private List<Fragment> getFragments(){
List<Fragment> fList = new ArrayList<Fragment>();
EventListFragment eventListFragment = (EventListFragment)
EventListFragment.instantiate(this,
EventListFragment.class.getName());
EventGridFragment eventGridFragment = (EventGridFragment)
EventGridFragment.instantiate(this,
EventGridFragment.class.getName());
fList.add(eventListFragment);
fList.add(eventGridFragment);
return fList;
}
The getFragments is called here, on the OnPostExecute of the AsyncTask
protected void onPostExecute(JSONObject jsonObject) {
try {
getEvents(jsonObject);
setContentView(R.layout.eventlist);
List<Fragment> fragments = getFragments();
pageAdapter = new MyPageAdapter(getSupportFragmentManager(),
fragments);
ViewPager pager = (ViewPager)findViewById(R.id.viewpager);
pager.setAdapter(pageAdapter);
}
Fragment 1 : OnCreateView
@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
eventObjects = ((EventsActivity)getActivity()).getEventObjects();
setRetainInstance(true);
View view = inflater.inflate(R.layout.eventlist ,container,false);
final ListView listView = (ListView) view.findViewById(R.id.listView);
listView.setAdapter(new MyCustomBaseAdapter(getActivity(),
eventObjects));
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
Object o = listView.getItemAtPosition(position);
EventObject fullObject = (EventObject)o;
System.out.println("asd");
}
});
return view;
}
}
Fragment 2:
@Override
public View onCreateView (LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setRetainInstance(true);
View view = inflater.inflate(R.layout.eventgrid ,container,false);
GridView gridView = (GridView) view.findViewById(R.id.eventgrid);
gridView.setAdapter(new ImageAdapter(view.getContext())); // uses the
view to get the context instead of getActivity().
return view;
}
