Show toast on screenshot on a secure app

[shariful2011]

How can I show a toast when the user wants to take a screenshot of my app which is under your very good package? I used the example for testing purposes. Your early response will be highly appreciated.

You can easily show a snack-bar, when the user tries to take screenshot.

@shariful2011 sorry i missed your question. You are on Android?

@neckaros yes. Also I found out that on some phones it shows a snackbar.
