If you want to execute any code from app A, it has to be already installed (it's obvious, isn't it?), so you can't check from your app A whether your app APP is installed or not.

It's like if you want to know when you are dead: after you die, it will be impossible to know it. On the other hand, someone else can know when you die... same for the Android scenario: an app B can know whether app A is installed or not (by using getInstalledPackages or intents or whatever).
