82.15 Summary

Once an app project is either complete, or ready for user testing, it can be uploaded to the Google Play console and published for production, internal, alpha or beta testing. Before the app can be uploaded, an app entry must be created within the console including information about the app together with screenshots to be used within the Play Store. A release Android App Bundle file is then generated and signed with an upload key from within Android Studio. After the bundle file has been uploaded, Google Play removes the upload key and replaces it with the securely stored app signing key and the app is ready to be published.

The content of a bundle file can be reviewed at any time by loading it into the Android Studio APK Analyzer tool.
