Hi @GWAK
Earlier I was involved in some other work so was not able to reply. You can download and set Gradle as an environment variable. There are various ways to set the environment variables for various operating systems. The process would be quite similar to setup java in the system. After you would be able to use Gradle commands on the command line, you can export the project and navigate to the exported project’s folder in terminal or cmd based on your system. Now you can try to run the following command:
gradle bundleRelease
after that, the bundle would be generated at this location as
/sketchbook/project_name/android/app/build/outputs/bundle/release as “app-release.aab”
as mentioned in detail in this thread
Thanks,
