How to add the BILLING permission to your APK.

Google Play: To add in-app products, you need to add the BILLING permission to your APK.

As far as I know the expo-in-app-purchases adds that permission ( if it is needed ).

You can confirm this in your app by running a build ( expo build:android -t apk --release-channel my-test-channel-123 ) and then investigate the resulting APK file with AAPT2 or apktool. You can simply text-search the directory for “BILLING”.

UPDATE:
Anyway, I think it does not include it because it is not required since 2017:

Although a comment under that answer says:

This is true and useful, but your app still does need that permission. It’s just that the library now does it for you, you don’t hand-modify your AndroidManifest.xml. If you look at the the final merged AndroidManifest.xml file after building, you’ll see that it’s there after adding the library. – James Moore Oct 31 '19 at 18:59

I’m not sure how that happens with Expo, but presumaby it should happen during the build.
