I integrated the library successfully for iOS and wanted to also do the same with Android. However, when I upload my build to the play console, I get the following error:
"We have found that at least one of the app bundles included in this release uses the following Play Billing Library versions:
AIDL
These versions of Google Play Billing are no longer supported. Upgrade to a supported version to publish this app. More information" (translated)
I have checked the dependencies, only v 6.0.2 appears

I added this line to the manifest “<uses-permission android:name="com.android.vending.BILLING"/>”, other than that I didn’t add anything else.
