Google play console shows warning when release application bundle

Question

The problem is that I don't import any version of google play billing, neither i declare billing permission in my manifest.

Error :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 will check in my code no any billing dependency and no any permission for billing still i don't understand why this error coming in play console.

Answer 1

It means that some library you're using in your project could have an inner dependency on an old version of Google Billing. You can run in your terminal either

gradle dependencies

or (if you're using the gradle wrapper)

./gradlew app:dependencies

When it pastes you a complete tree of dependencies, you'll be able to find the needed library.
