Internal apps are company-specific apps developed by your organization that you may not necessarily want to be searchable in the public app store, but you want your users to have access to this application from their device.
If you are using Android 6.0+ devices as Work managed devices, add these apps to AirWatch Console so that they are available to Android for Work specific users. Once you have added your internal application to the AirWatch Console, these apps are treated as public applications.
For information on uploading internal apps for Work managed devices, see Upload Internal Applications with a Local File. Follow all directions in this section to get these apps approved, uploaded, and assigned to your users.
If you are deploying internal apps on Android for Work -Work profile devices, add internal apps to Google Play for Work so that they are available to Android for Work specific users. Upload your application by logging into the Google Play Developer Console with your enterprise credentials. There is an option to enable, Restrict Distribution, which only allows users of your domain to view this application on Google Play for Work (the badged play store). Once you have added your internal application to the developer console, these apps are treated as public applications.
