The new ContextAware API will be available in Activity 1.2.0-alpha08 and is used by Fragment 1.3.0-alpha08 and AppCompat 1.3.0-alpha02 to implement FragmentManager's and AppCompatDelegate's pre-onCreate() logic.

Wait, this can't work as advertised.
FragmentActivity extends ComponentActivity
public FragmentActivity(@LayoutRes int contentLayoutId) {
super(contentLayoutId);
init();
}
private void init() {
addOnContextAvailableListener(new OnContextAvailableListener() {
// ...
}
}
ComponentActivity
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
// ...
mContextAwareHelper.dispatchOnContextAvailable(this);
super.onCreate(savedInstanceState);
//...
}
- Call
FragmentActivityconstructor, - which calls
ComponentActivitysuper constructor, - which dispatches context available... to noone,
- and calls platform Activity.onCreate.
- Bubble up to
FragmentActivityconstructor and register context listener, - which is invoked synchronously but only after platform
Activity.onCreatehas already been called.
Did I miss something? I'm confused.

Never mind, constructor vs onCreate. :facepalm: Sorry.

Re #8 - the fact that these are different things is indeed exactly why this API exists :)
Description
Component used: Activity Version used: 1.2.0-alpha06
The APIs of
LifecycleOwnerprovide us with a callback for when you reach theCREATEDstate, but for activities that is often after some critical code needs to run.For example:
setThemeto reset your theme from a branded launch themesetLocalNightMode()These all need to be called before
super.onCreate()and specifically the inflation of any layout.It would be nice if there was a composable way to get a callback at that exact time without needing to manually add code to
onCreate()(which, will fine for app code, is hard to do as a library).
