Answer 1

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).

Answer 2

You can use http://developer.android.com/reference/android/content/pm/PackageManager.html#getInstalledPackages(int)

Remember to set the appropriate permission in your AndroidManifest.

You quoted the link to Android - How to intercept the 'Install application' intent - which would mean you like to know when you application was installed at all? Are you trying to check if people actually download your app? Basically I think it's not possible to do that.

But if you like to see if your app was installed, just check for a SharedPreference and if not possible, it's a fresh install.
