In app purchases in React Native (Android)

Good news is that you can use the simulator as long as the Google Play store is installed the emulator and you're logged into your google account.
Important note: In android you can have multiple subscriptions running at the same time, it doesn't just change the subscription like in iOS which is really neat so make sure you've the logic in place to handle that!
