Edit:
The PlayCore API now supports downloading the strings for another language on-demand:
https://developer.android.com/guide/playcore/feature-delivery/on-demand#lang_resources
Alternative solution (discouraged):
You can disable the splitting by language by adding the following configuration in your build.gradle
android {
bundle {
language {
// Specifies that the app bundle should not support
// configuration APKs for language resources. These
// resources are instead packaged with each base and
// dynamic feature APK.
enableSplit = false
}
}
}
This latter solution will increase the size of the app.
