Note that you must setRetainInstance(true); otherwise the Observable and all associated state will get destroyed of course. So make sure you don't create strong references to views/context in onCreate or onActivityCreated, or they will leak. The nice thing about this is that there apart from splitting up the code for creating the observable from…

	package com.github.super8.fragments;

	import android.os.Bundle;
	import android.view.LayoutInflater;
	import android.view.View;
	import android.view.ViewGroup;
	import android.widget.AdapterView;
	import android.widget.GridView;

	import com.github.super8.R;
