"We've detected this app uses an unsupported version of Play billing" for Xamarin Forms Android App

Question

When attempting to publish my Xamarin Forms app, I get the following error from Google Play console

We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 3 or newer to publish this app.

I don't use any billing library. I've tried updating all nuget dependencies, to no luck. How do I fix this error so I can publish my app?

Answer 1

Apparently I had BILLING permissions set in my manifest. Removing these fixed the issue.

You can do this by right-clicking the project --> Properties --> Android Manifest --> Searching for BILLING under "Required Permissions" and unchecking it

Alternatively, open AndroidManifest.xml and delete the line

<uses-permission android:name="com.android.vending.BILLING" />

Answer 2

use this in your manifest application tag

<service android:name="com.google.firebase.messaging.MessageForwardingService" android:permission="android.permission.BIND_JOB_SERVICE" android:exported="false"></service>

and remove this : permission android:name="com.android.vending.BILLING"

Answer 3

Add the below implementation app/build.gradle file. It solved my problem. The project was build using Flutter.

dependencies {
implementation 'com.android.billingclient:billing:4.0.0'

}
