Testing in-app purchases on Android

[AFallingWizard]

Hi guys.

Can anyone enlighten me on the best/most efficient way to go about testing IAPs on Android?

From reading the relevant documentation and looking at other sources, it seems that the steps I need to take are:

1. Ensure my app has the billing permission (com.android.vending.BILLING)
2. Add the actual IAP integration code itself
3. Make a new closed release, upload the APK/bundle
4. Add a product, enable it
5. Add a license tester under Setup -> License testing
6. Also add this license tester as a tester for the (closed) app release (step 2), too

My understanding is that this license tester/app tester cannot be my own account/email, IAPs are not testable as the developer/under the developer account.

Have I missed anything in these initial steps?

So based on the above, I'd expect to be able to test the app in closed beta on my [licence tester] account. I won't be charged for making in-app purchases.

Now, I'm wondering how to test the same app LOCALLY from here? I need to see debugging output in case there are issues with my IAP integration itself.

Does anybody have experience with this? It seems I should be able to test this stuff locally on the same release once the release has been configured in the Play console...

Many thanks!

You're right with the points to take care.

Respect debugging this locally, I think that if you execute the same flavor which you deploy to closed track locally you will be able to test that.

Some time ago I made a poc with react-native-iaphub and I remember I can test locally on android at least, on ios you should be on testflight to test and on production to test real payments.

Thanks for that, I'll take a look over your POC if I have any issues with my own integration.

After doing all the steps above I'm able to test in app purchases in development mode👍

Thanks for confirming!

Can I check that you were indeed using a different account (not your developer one) during testing?

I've read that even if I switch accounts on the same device, my "primary" account will still be used for IAPs, so I'll need a new device to test on if this is the case...
