We find that there is a DependencyInfoBlock in your APK.

It's a Signing block added by AGP and encrypted with the Google public key so it can't be read by anyone else except Google. You can read more about it here, here and here.

While this was added a while ago, we were only enforcing it for new apps, and recently we started scanning updates too.

Could you please disable it with the following code?

android {
    dependenciesInfo {
        // Disables dependency metadata when building APKs.
        includeInApk = false
        // Disables dependency metadata when building Android App Bundles.
        includeInBundle = false
    }
}

Thanks!
