How to Hack Android as a Pro

Hello guys im new here , first i loved this site alot it is solved alot of my problems

okay as we know if we creat an android payload and send it , it will have a MainActivity name , with blank screen , so the victim will remove it as soon as u know , so it is noob payload ! :(

so in my opinion there are two ways to make the victim dont able to remove it:

first: embed the payload with any apk like fb.apk .... etc, but if u do that u cant devlope the payload any more ......

the seconde i think it is a new idea that make the payload.apk work as widget !! is that possible ? im sure that is possible but im very noob in java and android studio

but if we did that the payload will not have an icon in android screen and dont not have background in task manger

so can any one help me ???
