How to intercept the actions of someone else's activity?

Question

Android

My app launches an activity from a linked library. Those. it opens, which I do not like how it works. In particular, the back button. I would like to be able to intercept the return method call from an activity in a linked library. How can I do that? The activity there is not mine at all, I literally write: PseudoLib.showMegaBoom() and an activity appears from which others open, etc.

Answer 1

Inherit the necessary classes, incl. launched activity, and overwrite the necessary methods.
