In Android app development, there are occasional exceptions that cause the app being used to be abnormal and forced to shut down, which leads to an unfriendly user experience. To solve this problem, we need to catch the exception and do the processing.

. You can crop the outline of a view using a View.setClipToOutLine() method, or a android:clipToOutline property. Only rectangles, rounded rectangles, and circle outlines are clipped, and you can use Outline.canClip() methods to detect whether the support is clipped. 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
