for example have two app,You can use PackageManager from the phone library to check whether any specific app is installed. You can then unlock whichever features you like.
Thanks for your response, i will try to find the tutorial, i hope it's available in this forum1. the cheater must know the name of the package (myapp.app.unlocker) to do such a cheat
2. If you want to make it more safety you can follow the inapp billing tutorial. You then get a "list of all products the user own" and compare this list to whether he buyed myapp.app.unlocker or not....
Sorry to ask 1 more time, i just want to make sure ,

Hello erel, now i am really confuse about making app unlocker, because it is too easy to guess the package name, it's written on url of google play storeYes.
thank you for your response, ok this is what i am thinking, if i have two app , myapp.free.version & myapp.unlocker.versionThe package name is not secret.
Yes, you can use in app purchases to implement such a solution.
Thanks for suggestion, now i am creating 1 app with in-app-billing-service enabled, then there's a new problem here, actuallyYou don't need two apps. Create a single app and open the locked features after the user makes a purchase.
