Overview
Managed configurations are part of a specification developed by Google and the Android community for remotely configuring installed applications and devices through any Enterprise Mobility Management (EMM) system that supports it. Originally known as "App Restrictions" because of their limited initial scope, managed configurations (MCs) are now being used by Zebra to remotely configure a variety of settings, including those for device hardware, software and security.
The features of a given app that are manageable using MCs are defined in its schema. The EHS schema is downloaded when visiting Google Play through the EMM console and selecting EHS for administration. The schema defines the features available for consumption by the EMM, and provides the information necessary to present the app's management UI within the EMM console.† This data-driven UI method allows delivery of new features and their corresponding UI attributes as soon as they become available, and without the need to download a new .exe. For more information about configuring Zebra devices with managed configurations, see Zebra OEMConfig.
† The EHS management UI varies slightly depending on the EMM system in use.
Configuring EHS with MCs
At present, the full suite of EHS settings can be administered only through the EnterpriseHomeScreen.xml config file. Over time, Zebra plans to increase the features manageable through MCs until all are included, at which time the use of the EnterpriseHomeScreen.xml config file will be deprecated.
Current MC Capabilities:
- Securely mass-deploy EHS settings files across an enterprise
- Limit device-user access to approved apps only
- Prevent unauthorized changes to device apps and settings
Requirements
- One or more Zebra devices running Android 11 or later
- A supported EMM with EHS and its schema downloaded from Google Play
- EHS 5.0 (or later) installed on device(s) (can be deployed by EMM, if necessary)
