- _asummers 12y agoI believe that SnapChat alerts the sender if a screenshot happened. While this doesn't prevent the action, obviously, it at least lets the sender know.
- kuschku 12y agoIt actually has — Apps can prevent the system from taking screenshots by telling the DRM hardware chip that they are showing important data. Actually you can even prevent users from obtaining the data if you encrypt it with a secure key and store this key in the DRM hardware chip. Only problem: Someone could still decompile your app, use your API and request the decryption keys.
- izacus 12y agoUhm, Android had an API to disable screenshots since forever - see http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html#FLAG_SECURE http://developer.android.com/reference/android/view/WindowMa... . As soon as you add this flag to the Window, the contents will disappear from screenshots or device will refuse to make them (depending on Android) version. The reason why Snapchat has screenshot notification is actually due to that API being absent from iOS for a long time.
