Application Manager (AppMgr) administers the user applications on the device. It can be used to programmatically install, uninstall, upgrade and turn on (or off) the ability to launch an application, all with no need for user interaction. AppMgr also can designate an application as the Default Launcher (invoked when pressing the HOME Key), and can perform other tasks related to the management of applications.
On consumer Android devices, app management generally requires the user to interact with a management UI presented on the device. For corporate scenarios involving management by an Enterprise Mobility Management (EMM) system (sometimes referred to as mobile device management, or MDM), user consent or approval might not be desired as they potentially limit a company's ability to fully control the user apps installed on a device. AppMgr provides such control.
When considering the capabilities of AppMgr, it is important to understand the difference between System apps and User apps. System applications are built into the device and always by default. User applications are not built in, and must be installed before use. Some AppMgr functions apply only to System apps, some only to User apps, and some to both. Each function identifies the class of the app(s) to which it applies.
.apk, .apks, .xapk and .zip for package-file ActionsPackage names can vary from one Android version to another.
GMS Restricted Mode: In response to security concerns, Zebra has implemented GMS Restricted Mode, which allows administrators to disable some or all GMS apps deemed "safe to disable" without interfering with normal device operations. See GMS Manager for more information.
The evolving security practices employed by Android have changed the user experience in Android 10 to give greater control to the device user. Such changes could impact the enterprise use cases of Zebra customers. To implement the necessary functionality while maintaining device security, MX 10.0 provides the IT administrator with the ability to silently (without device-user interaction) grant application runtime permissions typically used by remote management systems. For some of the Actions executed by this CSP, including Install and Upgrade, apps must be targeted at Android API level 23 (or newer) to be silently granted runtime permissions on devices running Android 10 or later.
The App Manager allows one or more apps to be added to the Battery Optimization "exemption whitelist." While running, apps on this list prevent the device from entering Doze and App Standby power saving modes, thereby preserving their ability to continue functioning and/or providing services. Doze mode conserves battery power by deferring background CPU and network activities when the device is idle. App Standby defers background network activity for apps with which the user has not recently interacted. By default, all non-system apps are subject to Doze and App Standby modes unless added to the whitelist.
For more information, refer to the Android Developer site.
Virtual keyboards (aka soft input panels) are enabled and disabled by referenceing their package name with the desired AppMgr Action. Some of the most common keyboards are listed below:

Used to enter an Action or app-related setting to perform on the selected app. Actions can apply only to System apps, only to User apps, or to both (as noted in the table below).
Use of the "DisableApplication" option to prevent launch of the Android System Settings app on the device could lead to unwanted system behavior. Zebra recommends using Access Manager's System Settings Access feature to limit or prevent user access to System Settings on a device.
GMS features are supported only on GMS-enabled devices.
See GMS Manager for more information about GMS Restricted Mode.
Note: For Install and Upgrade Actions, apps must be targeted at Android API level 23 (or newer) to be silently granted runtime permission on devices running Android 10 or later.

Used to enter the path and file name of the Android .apk or other supported file in the device file system from which to perform an app installation or upgrade. In addition to .apk, some devices support .apks, .xapk and .zip "App Bundle" formats for deploying multiple, device-dependent .apk files (plus optional app data) bundled as a single file. See Notes below.
.apk file can be used only to Install or Upgrade a User app or to Upgrade a System app..apk file is by definition a User app since it was not built into the device..apk file must be signed with the same developer certificate as the app it is intended to upgrade or an error will result..apk file produced by the same developer that produced the built-in System app. .apks, .xapk or .zip file formats..apk file(s) and the (optional) corresponding .obb APK Expansion Files. .apk MUST contain only a SINGLE base .apk..apk and all splits must be identical. .apk and all splits must share the same signing key..obb files are used, they must be named according to Google Play naming guidelines. Learn more about App Bundle files.

Used to allow blocking of access to App Info for all applications without blocking access to other parts of the Android Settings panel. When disabled, the device user is prevented from using App Info to interfere with the configured set of installed applications.
Since the AppMgr can control which applications are installed, it might be of concern that a device user can use the App Info section of the in-device Android Settings panel to impact an installed application. For example, a device user might terminate (Force Stop) an application, remove application data (Clear Data), or even Uninstall the application completely. If an MDM/EMM system is being used to control the set of installed applications on a device, such user activities might be undesirable.
Compounding the issue, the App Info can be reached from several places in the device UI other than the Android Settings panel. For example, App Info can be reached from the Recent Apps list or from a notification related to the application in the Notification bar.
To prevent device users from using App Info to alter the configured set of installed applications, it might be desirable to prevent the device user from accessing App Info altogether. Of course, AppMgr can be used to disable launching of the System Settings Menu application, prevents access to App Info. But that also prevents access to all other aspects of the Settings panel. A more targeted approach is to block only App Info.
