Who and according to what principle transfers applications to Google Play?

Question

Google Play

On Google Play in the developer console, under "Optimization Tips", the following tips sometimes appear:
"The data for the Google Play Store or the APK file of the application has already been translated into French and Arabic. Localize the images so that it is easier for users to understand the purpose of the application."
"The APK file has already been translated into French, Arabic and Turkish, but the data for the Google Play Store is not yet available."
What does this mean? That someone translated the application's strings.xml?

Answer 1

Standard libraries like play-services or appcompat have translation strings for many languages. If you do not cut them out of the build, Google Play shows as if the application has been translated into these languages, it is possible that users are being misled by this, I don’t know for sure.
Extra lines are cut very simply (Gradle settings):

android {
  defaultConfig {
    resConfigs "en", "ru" // skip resources for any other language
  }
}

This is also useful in terms of slightly reducing the size of the build.

Answer 2

I translate only into Russian and English. For all other languages ​​I put the English version. For any languages ​​in which he recommends to do localization - I put the English translation.
If the program is very popular, then it will be possible to honestly translate it.
