Google has an app called Google Opinion Rewards that shows the user's Google Play Balance on screen without having to initiate an in-app purchase.
I would like to do something similar: with given permission, fetch the user's balance and display it on screen. So far I found nothing about that. The only way I found so far is to initiate an in-app purchase that would show a new window where the user would be able to pick a payment method and thus see their current credit balance.
Any direction will be very appreciated.
Only got to this documentation so far, which doesn't help much. https://developers.google.com/android-publisher?hl=en-us#subscriptions
I am not sure if that is a Google Play, Google Services or Google Pay issue.
