The system does not control whether the stack has the same activity, in the same way as after-in first-out.Singletop mode is when the activity starts, the system first determines whether the t

Crop the view to a drawable shape, set drawable as the background of the view (let the view appear on it), and call the View.setClipToOutline() method. Cropping a view is an expensive operation and does not use shape animation when
