According to the documentation for implementing admob, I need to add the com.android.vending.BILLING permission. But by adding this permission, the Google Play Store listing adds a marker claiming that the app has In-app purchases. My game does not have any in-app purchases.
Upon doing research, no one else, as far as I saw, seems to use this permission when using admob. I believe the only permission admob actually needs is android.permission.INTERNET. How come the documentation requires this?
