Where other applications find what apps i have installed

[MrNob0dy]

Stack Exchange makes me mad because of that proper grammer rule.. soo i post my question here.

Some games or apps require to install other apps instead to pay for some in app features. Where is recorded that kind of data, i think this is in some .prop files, but i just guess..

From PackageManager, like this:

public static boolean isPackageInstalled(String pkg) {
		try {
			pm.getApplicationInfo(pkg, 0);
			return true;
		} catch (NameNotFoundException e) {
			return false;
		}		
	}

From xposed - yes. Or by patch target app.

@NoFear always tells me to use XPrivacy, its a xposed module that can disable app detecting. I have never found out how to do it though so he might be able to explain.

Xprivacy I don't think can spoof something installed. Definitely can restrict another app from seeing it.
