Is there a way to change the thumbnail of an app in the android task switcher (long press on home button)

Question

is there a way to hide / mask the thumbnail of an activity proposed in the task switcher ? By task switcher, I mean the menu that displays active applications with a long press on the home button.

Thanks in advance !

You can override Activity.onCreateThumbnail() to do this.

This is not working on many devices. See this thread: http://code.google.com/p/android/issues/detail?id=29370 – r.bhardwaj Jul 16 '14 at 12:51

The callback is actually _never invoked_ in most Android versions, as can be seen in the source code – salezica Mar 05 '18 at 17:29
From Activity documentation: "This method was deprecated in API level 28. Method doesn't do anything and will be removed in the future." – happydude Oct 11 '18 at 09:58
