Hi guys, I am just trying to implement Google Play Services etc. to my android games, even the Google Play Billing. I figured out it to work thanks to YoYo Games tutorial, I can buy a product and I will get the reward, but every time the game lost internet connection or I start the game without it, it show me a pop up window "please ensure you have an active data connection for license check" (attached screenshot). I don't know, what to do with it, it's even showing while playing and that's pretty disturbing. I have tried to add the Code: os_is_network_connected() if statement in every event of my GPBilling objects, but it's doing just nothing. I have also tried to check connection via Code: GPBilling_IsStoreConnected() and Code: GPBilling_ConnectToStore() , but it didn't help as well. So, I don't know what to do right now, does anybody of you have any idea? And please, does anybady of you know, how to secure refunding? I mean, if a player buys an app and refund it, my game have to take that bought item from him. I didn't find anything about this. Thank you very much!
