I am developing a lock application as an academic project. I need to detect the launch of an app so that i can launch my lockscreen on top of it and restrict opening the app till the user put correct pin. I have read a few posts and this one has a few answers that look promising.
Android, Detect when other apps are launched
Is this the right way to do it? Or is there a better way around? I have also heard about the Application
class. But don't know how to implement it.
EDIT: My app supports API16 to API22.
