Is Activity.onStop() guaranteed to be called (API 11 +) -
it unclear (to me, @ least) documentation whether activity.onstop guaranteed called. there 2 places seemingly contradictory information.
- javadoc activity.onstop:
note method may never called, in low memory situations system not have enough memory keep activity's process running after onpause() method called.
- documentation (in particular 'killable' column) activity class http://developer.android.com/reference/android/app/activity.html#activitylifecycle:
starting honeycomb, application not in killable state until onstop() has returned. impacts when onsaveinstancestate(bundle) may called (it may safely called after onpause() , allows , application safely wait until onstop() save persistent state.
it's bit of struggle find way both pieces of documentation telling truth. scenario can think of this: suppose developing on target api 21 (with min sdk 10) , write activity onstop() method. if run application on api 10 phone, onstop() not guaranteed called. scenario means documentation points 1. , 2. above both true. otherwise, 1 of them must false.
is
activity.onstop()guaranteed called (api 11 +)
yes, guaranteed called on post-honeycomb devices (api 11 +)
