Remarks
Add a new ComponentCallbacks to the base application of the Context, which will be called at the same times as the ComponentCallbacks methods of activities and other components are called. Note that you <em>must</em> be sure to use #unregisterComponentCallbacks when appropriate in the future; this will not be removed for you.
After Build.VERSION_CODES#S, Registering the ComponentCallbacks to Context created via #createWindowContext(int, Bundle) or #createWindowContext(Display, int, Bundle) will receive ComponentCallbacks#onConfigurationChanged(Configuration) from Window Context rather than its base application. It is helpful if you want to handle UI components that associated with the Window Context when the Window Context has configuration changes.
