应用程序可以在Application.onCreate（）之前获取Fragment.onAttached（）吗？

Is there any dependency between Application's and Activity's/Fragment's lifecycle? Is it possible to get Activity.onCreate() or Fragment.onAttached() before Application.onCreate() ?

Answer 1

Is there any dependency between Application's and Activity's/Fragment's lifecycle?

The Application singleton for your process will be created before any activities, let alone fragments.

Is it possible to get Activity.onCreate() or Fragment.onAttached() before Application.onCreate()?

Not in any conventional scenario.

Answer 2

No, it is not possible. Refer the mention in documentation below for onCreate method of Application class.

public void onCreate()

Called when the application is starting, before any activity, service, or receiver objects (excluding content providers) have been created
