是否可以让后台进程检测屏幕捕获

Question

I want to build n app that detects when the user takes a screenshot then get the image and use it.

Is it possible without root? My idea is very crude. the app will scan the screenshots holder for changes every second but that is very inefficient. is there another way?

I don't think there is no supported way of doing that. You could try the FileObserver class though and watch for events. Look here: https://developer.android.com/reference/android/os/FileObserver.html
