      Calling

      QLocale().uiLanguages()

      doesn't work as expected on Android 6.x where is always return an empty list. The same bug also happens when using the QML version:

      Qt.locale().uiLanguages

      The main effect is that calling the load method of a QTranslator passing a QLocale() as first argument simply doesn't work, and apps are not translated.

       

      I attach a simple test app reproducing the issue.

       

      Result on x86 Android emulator with android 6.0

       

      Same apk on Android 9.0, works properly.
