I'm looking for immediate support to resolve the "Error 3 - Code Already Used" I receive when attempting to upload an AAB package to the Google Play Console. Current Situation • The app compiles and launches successfully locally. • When uploading the AAB release, the console blocks the publication, reporting Error 3 with the message "Code Already Used." What I Need 1. Quick analysis of the Gradle project to identify the cause (versionCode/versionName, signature, automatic increments, any pending artifacts). 2. Correction of the offending parameters and generation of a new signed AAB. 3. Successful upload of the release to the Google Play Console with my confirmation. I will accept the job when: • The corrected AAB is accepted without errors by the console. • I receive brief notes on what has been changed to prevent the issue from recurring. We work with Android Studio (latest stable) and an updated Gradle wrapper; I'll provide a keystore, limited console access, and a private repository. I'm looking for someone who's already worked around this exact bug and can get it done in a few hours.
