All work apps that you want to make available to your users must be distributed through Google
Play for Work.
- Public work apps are apps that are available to all users with an Google Play for Work
- Private work apps are apps developed by you that are only available to users inside
- Self-hosted work apps are private apps for which the application package (that is the
APK file) is located on a server belonging to your organization instead of the Google server.
However, the app store metadata for self-hosted apps must be uploaded to Google so that the app
can be distributed through Google Play for Work.
For information on private work apps, see the Android for
Work Developer web pages (external link).
