Don't add external dependencies to a View - service bind, network call. Fragments integrate with lifecycle and may be aware of other app components. Bind to a service, communicate with data model. FragmentManager.beginTransaction() .replace(R.id.container, fragment1) .addToBackStack("state1") .setReorderingAllowed(true) .commit(); Optimisation
