If a developer turns ON Google Play's Anti-Piracy setup, the application cannot access the play services if it is not installed from Play Store(so says Google). My question is how Google verifies this? More than that I need to know, if I can install an application from the play store, then modify the apk and then re-installs it in my phone manually(by enabling 'install from unknown sources') AND then use the play services?
