Android Question In-App Purchase setup

[MitchBu]

I am trying to setup in-app purchase for my app Check Printer+, using the library here:

GooglePlayBilling - In App Purchases

The previous service which was used by InAppBilling3 library is being deprecated and will soon won't be available. GooglePlayBilling is based on the new in app purchases service: https://developer.android.com/google/play/billing/billing_library_overview Usage instructions: 1. Add to the...

www.b4x.com

The idea is to have a free app, Check Printer Free with some limitations, containing the in app purchase for Check Printer+, the full feature app.

I copied all relevant code from the example Starter module, as well as in the Manifest editor, into Check Printer Free.

Now, following the instructions at https://support.google.com/googleplay/android-developer/answer/1153481 I am trying to create a Managed Product with Check Printer+, so I can setup an in-app purchase within Check Printer Free.

When I try to do so, I get :
---
Your app doesn't have any in-app products yet.

To add in-app products, you need to add the BILLING permission to your APK.
Upload a new APK

How do I add the Billing Permission to Check Printer+, so I can make it a managed product ?

TIA

How do I add the Billing Permission to Check Printer+, so I can make it a managed product ?

The billing permission should be added automatically:

This is a project based on the billing tutorial.

Sorry, Erel, I don't see what you posted.

I have added #BridgeLogger: True to the billing example project, but the permissions don't show.

I tried to add the GooglePlayBilling library to my Check Printer+ project, plus a billingclient object, and I initialize it, but yet, no added permissions...

 

[Erel]

This is the dialog that lists the permissions. What do you see when you click on the List Permissions button?

 

[MitchBu]

Oh, now I see it. Thank you so much Erel.

Please forgive my ignorance.

Little by little, I am hopefully getting closer to succeeding into implementing in-app purchase.

After reading carefully Google's documentation, I created a managed product at https://play.google.com/apps/publis...jardet.checkprinter&appid=4975675971907266849

This time, the Google UI did not complain there was no com.android.vending.BILLING in the app. I was able to create the managed app, to set the price. Everything seems OK.

Yet, in spite of making sure to put the proper app ID in ADS_SDK_ID and the proper key in BILLING_KEY, SkuDetails.size = 0 and I get the error:

I suspect it must be something simple, but I don't seem to spot the issue.

There must be other B4A users who have successfully implemented in-app purchase with this library.

Any hint will be greatly appreciated.

Did you put a beta version of your app - with the purchase option - in the Play Store?

Not yet.

I migrated the old lib to the new lib in my app. It worked fine. I think you need to put a beta version with the purchase option in the Play Store to "activate" this.

 

[MitchBu]

Thanks Asales, I will try and report

Hi Asales,

It should be the same app, with the same ID as the paying one ?

Yes. Put it as Beta in the Play Console.

 

[MitchBu]

Yes. Put it as Beta in the Play Console.

Alright. Thank you Asales
