Aurora: install downloaded App?

Is it possible to install a App, that is downloaded via Aurora (Google Play Store)? The App is only available on Google Play Store. The Aurora download settings are setted to deactivate “Delete APK post-install”. In the directory Aurora/Store/Downloads/com.user.appname/12/ are two files:

  • base.apk
  • config.xhdpi.apk

Is it possible to install this Apps without the Aurora Store (Google Play Store), also offline?
