Hi:

I'm triying to distribute the app through the Google Play and 

• if I upload the APK generated from the package created in PB I have the message:
  
  

APK without optimization
Warning:

This APK has unused codes and resources that are being sent to users. Reduce the size of your application with the Android App Bundle. If you don't optimize your app for different device settings, it will be too heavy to download and install on user devices. Heavier apps have lower download volume. Furthermore, they take up a lot of storage space on users' devices.

Solution:

Use the Android App Bundle to automatically optimize for different device settings, or manage it with multiple APKs.

• And if I triy to generate the App Bundle, I have this error:

File 'root/classes2.dex' uses reserved file or directory name 'classes2.dex'.

Someone has been the same? Any suggestion?

Thanks, 

Oihana
