Generate Apk file from aab file (android app bundle)

So far nobody has provided the solution to get the APK from an AAB.

This solution will generate a universal binary as an apk.

1. Add --mode=universal to your bundletool command (if you need a signed app, use the –ks parameters as required).

   bundletool build-apks --bundle=/MyApp/my_app.aab --output=/MyApp/my_app.apks
       --mode=universal
   

2. MAIN STEP: Change the output file name from .apks to .zip

3. Unzip and explore

4. The file universal.apk is your app

This universal binary will likely be quite big but is a great solution for sending to the QA department or distributing the App anywhere other than the Google Play store.
