In app purchases in React Native (Android)

In this video I'll show how to get up and running with in app purchases (subscriptions) in React Native for 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!
Libraries used:
googleapis
react-native-iap
The steps showed in the video:
Pre steps:
- Sign up for the Google Developer program
- Submit a release, upload apb and get it approved
- Create service account in Google Developer Console
- Add owner rights to the service account and link it in the Google Play Console
- Add subscriptions in the Google Play console and activate them
In the app:
- getSubscriptions()
- requestSubscription(productId)
- purchaseUpdatedListener
- Save Receipt in backend
- finishTransaction()
Backend:
- Backend code, receipt validation, (productId, receiptToken), check for paymentState === 1

[@amandhiman557]

If we have Android, iOS and Web version of app and if i purchase subscription in iOS using in all, will it work in web and mobile version.

In the Pre steps, i.e submit a release, upload apb and get it approved step,
Should I upload the apb version of the app without integrating payment system in the react native app?

[@jonasgroendahl]

Dont need to upload a version with the payment system in place :) its up to you

[@sagarraturi7283]

Hello bro, i have two questions
1:- did i need to publish my app before integrating react native iap in the app
2:- Can i test the app in dev mode because as far as i know only the release build can be uploaded for testing and in release mode react native debugger does not work

[@jonasgroendahl]

You need to upload at least one build to Google play, you can test the app with simulator OR device with Android (be sure youre logged in with your Google account)

[@rashijain7773]

Hi how can i handle the subscription cancel and resubscribe from the google play store in the app. because I need to update the database if the state of the subscription changes.

[@jonasgroendahl]

Rashi Jain if you verify the receipt every time the user opens the app, you will know the currrent status of the subscription and you can update your database accordingly 🙂

[@lawsonnguyen6380]

Hi . Can you help me ? When I test the subscriptions ,I got error "the item you were attempting to purchase could not be found". It's works perfect if i installed from GG play .

[@jonasgroendahl]

Lawson Nguyen I’ve not had that error before so Im afraid that i cant help with this one

Hello there, thank you for the tutorial.
I have a problem when accessing the android.test.purchased by hitting the requestPurchase(), it shows the requested item is not found. I tested this APK in Alpha but none success. Do you have a similar problem?

[@jonasgroendahl]

Oda Nicola it sounds like you’re testing the ones in the example. You should create your own products for your own appId after doing the initial setup steps

[@mrnicolaoda]

@@jonasgroendahl Oh yeah, i don't even try any of your examples, this is my own app. What should i do? I created a new product too but it won't be retrieved. Should i have a service like the video says for the products? My app isn't game category.

[@jonasgroendahl]

Oda Nicola was your app approved? Might need to wait for that :)

[@mrnicolaoda]

@@jonasgroendahl oh yeah, now it is working fine. I need to publish and wait for the approval. Thank you for your reply.

[@jonasgroendahl]

Oda Nicola perfect, usually it takes 1 Day :)

[@jonasgroendahl]
