I am going to be supporting In-App billing/ purchases in my app.
From what I have read, it seems the Play Store app must be installed on the device in order to do In-App billing. I have 2 Android devices for testing. Both are missing the Play Store app. I am sure this situation will exist for users of my app.
Question: What does an Android developer do when their app supports In-App billing but the Play Store app is not installed on the device?
