Is there any implementation based on com.google.firebase:firebase-crashlytics:17.0.0?Note: The Fabric SDK is now deprecated and will continue reporting your app's crashes until November 15, 2020. On this date, the Fabric SDK and old versions of the Firebase Crashlytics SDK will stop sending crashes for your app. To continue getting crash reports in the Firebase console, make sure you upgrade to the Firebase Crashlytics SDK versions 17.0.0+ for Android and 4.0.0+ for iOS. Note that crashes sent from the Firebase Crashlytics SDK are only available in the Firebase console.
