Android: run another app instead of requested

Question

I write 2 applications for Android: A and B. All seems OK, but my task is very specified. It's not practical, it is learning low-level Android capabilities.

I need simple following: listen a LAUNCH intent of app A in app B or another way if you know.

The result must be: when I press app A icon, app B must started.

Not in onCreate! I know this method very well, but not a single line of application code A should be executed. Just run app B immediately. I control both apps A and B, I write them. How I can do described?

Very similar Two launchers for a single activity, only I need to redirect alias to another application.

you have 2 different applications right? – Mahesh Keshvala Feb 19 '19 at 11:44 — Mahesh Keshvala, Feb 19 '19 at 11:44

Apps are isolated so luckily you cannot do that otherwise that would be serious security risk.
