• Activity and Fragment Lifecycle Methods
Q1. Which of the following statements is false?
1. When an Activity is shut down, its onDestroy method is
called, which in turn calls the onDestroy methods of all the
Fragments hosted by the Activity.
2. We used the onDestroy method in the MainActivityFragment
to release the CannonView’s sound resources.
3. Method onDestroy is guaranteed to be called, so it can be
used to release resources and to save critical data.
4. The Android documentation recommends that you save data in
methods onPause or onSaveInstanceState.
Answer: c. Method onDestroy is guaranteed to be called, so it can be
used to release resources and to save critical data. Actually, method
onDestroy is not guaranteed to be called, so it should be used only to
release resources, not to save critical data.
