I will publish paid app for android and ios. I want that one account can only install and run on one device. Otherwise I want to block the app on first device. Is there any way to do this?
Note: I know there is a lvl for Google Play. But I am not sure, it does this exactly. Sorry for my english.
What you seem to need to do, is to get the device_ID and pair it with the account.That shouldn't be hard.
You get the device ID when your customer registers ,than at login you check the login credentials AND the device ID...
Here's pretty much all you need regarding the device ID (not the login,I trust you can handle it yourself)
