Make the app content blank in the "recent apps" list-CodePudding

When the app is shown in the recents menu, I need to make the content blank, so that screenshots can not be taken. This flag works

 getWindow().addFlags(WindowManager.LayoutParams.FLAG_SECURE);

and the screen becomes empty white. I need to handle the scenario where the user has selected the dark mode, and so the screen must be empty dark.

What other options can I have other than using this flag?

Sorry, but you do not have control over how the OS displays your app in the overview screen, in terms of the color when FLAG_SECURE is used.

I have found this library on github that solves the problem.

You can use custom layout for the recent app views.
