OnBackInvokedCallback

public interface OnBackInvokedCallback

Callback allowing applications to handle back events in place of the system.

Callback instances can be added to and removed from OnBackInvokedDispatcher, which is held at window level and accessible through Activity#getOnBackInvokedDispatcher(), Dialog#getOnBackInvokedDispatcher() and Window#getOnBackInvokedDispatcher().

When back is triggered, callbacks on the in-focus window are invoked in reverse order in which they are added within the same priority. Between different priorities, callbacks with higher priority are invoked first.

This replaces Activity#onBackPressed(), Dialog#onBackPressed() and KeyEvent.KEYCODE_BACK
