Assets included in build? yes/no

Thanks for this info. So, if I change that to be along the lines of:

 "assetBundlePatterns": [
    "assets/audio/*"
 ]

In that instance, only the audio files would be included in the build(in the APK itself), but the image files would not be included. The image files instead would be hosted on the Expo CDN and downloaded/cached on first run of the application to be stored on local device memory for next use, reducing the size of the initial APK.

Did I understand that correctly?

Thanks again for taking the time.
