Try bind your service in Fragment.onResume
with registering broadcast listeners if available, and use Fragment.onPause
to unbind service and unregister listeners
Fragment Life cycle issue
Вопрос
I have implemented a Fragment and override its lifecycle callbackas as following:
@Override
public void onActivityCreated(final Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
dactivity = getActivity();
dactivity.bindService(new Intent(dactivity,EventosDatabaseService.class), this, 0);
}
@Override
public void onDestroy() {
super.onDestroy();
dactivity.unbindService(this);
}
It is documented that onActivityCreated call must heppen prior to onDestroy, then how come i get NullPointerException thrown because dactivity is null on onDestroy? what should i do to avoid it while making sure the binding wont produce a leak?
BTW, the RetainInstance of this fragment is false if that metters

work.
