EMDK For Android - 13.0

Overview

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.

Main Functionality

  • Install, Uninstall and Upgrade User apps (with no device user involvement)
  • Set an app to be launched by pressing the HOME key
  • Turn On/Off the ability of an app to Launch (Whitelisting and Blacklisting)
  • Clear the Recent Application List
  • Clear an app's cache (which stores the app's temporary files)
  • Add/remove apps from Battery Optimization exemption list (see below)
  • Enable all GMS apps
  • Disable all GMS apps that are safe to disable
  • Disable GMS apps in predefined groups
  • Enable/Disable access to app info
  • Reserve/Unreserve an Android unique ID (UID)
  • Enable/Disable individual app feature(s)
  • Enable/Disable background data individually by app
  • Enable/Disable app widget management by users
  • Allow/Disallow individual apps to be upgraded
  • Set preference for error detection on Upgrade Actions
  • Use .apk, .apks, .xapk and .zip for package-file Actions

Package 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.


Android File Security

Zebra strongly recommends using Secure Storage Manager for on-device file sharing and persistence. SSM provides greater security than the legacy /enterprise partition method and aligns with Google's long-term strategy for Android security.

For administrators, Secure Storage Manager processes are similar to those of legacy methods. For example, where the legacy method uses an on-device path for file deployment, SSM employs a URI specific to the sharing app. For complete instructions, see the StageNow guide Using SSM with AppMgr and FileMgr.


App Permissions

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.


Battery Optimization

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

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:

  • AI Type - com.aitype.android.p
  • AnySoftKeyboard - com.menny.android.anysoftkeyboard
  • AOSP - com.android.inputmethod.latin
  • Chrooma - com.gamelounge.chroomakeyboard
  • Fancykey - com.pinssible.fancykey
  • Fleksy - com.syntellia.fleksy.keyboard
  • GBoard - com.google.android.inputmethod.latin
  • Ginger - com.gingersoftware.android.keyboard
  • GO - com.jb.emoji.gokeyboard
  • Grammarly Keyboard - com.grammarly.android.keyboard
  • Hacker’s keyboard - org.pocketworkstation.pckeyboard
  • Minuum - com.whirlscape.minuumfree
  • Multiline O Keyboard - kl.ime.oh
  • OpenBoard - org.dslul.openboard.inputmethod.latin
  • Simple Keyboard - rkr.simplekeyboard.inputmethod
  • Swiftkey - com.touchtype.swiftkey
  • Vysor - com.koushikdutta.vysor

Action

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.

NOTES:

  • IMPORTANT: See Overview section regarding changes to Android 10 permissions.
  • Virtual keyboards (aka soft input panels) are enabled and disabled in the same way as apps, by referenceing their package name with the desired AppMgr Action. Disabled keyboards do not appear for selection in the Android Settings panel. See the Overview section for a list of virtual keyboards.
  • On some older devices, "Protected" Apps remain on the "Recent Apps" list after the list has been cleared using the "ClearRecentApps" Action.
    See Protected List Action parameter for more information.
  • When persisting the DisableGMSApps Action across an Enterprise Reset, the Action MUST be preceded by a bypass of the Android Setup Wizard to prevent unpredictable behavior. See Power Manager for more information.
  • EnableGMSApps and DisableGMSApps Actions are NOT supported on 8956-platform devices.
  • If upgrading a device to gain access to "GMS Restricted Mode" (implemented in MX 8.3 and later), the upgrade and related actions must be performed in the following order:
    • If apps were previously disabled using the "DisableGMSApps" App Manager Action, execute the "EnableGMSApps" App Manager Action.
    • Perform the device upgrade with a package containing MX 8.3 or later.
    • Perform "Restricted" GMS Manager Action.
    • Zebra recommends restarting the device following any Action that enables GMS restrictions.
    • If desired, use Persist Manager to safeguard the XML on the device.
      It is not possible to transition a device to a new OS and to implement GMS Restricted Mode using a single XML profile.

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.

Parm Name: Action

Option Name Description Note Status Requires
0 Do nothing This value (or the absence of this parm from the XML) causes no change to device settings.

MX: 4.1+

1 Install Installs the user app contained within an .apk file in the specified path on the device. If the requested app cannot be installed, an error is returned in the Result XML document. Note- Attempts to install an app with the same Package Name as one already installed on the device result in an error in the Result XML. To replace an app already installed on the device with a different version with the same Package Name, use the Upgrade action (option 3).

OSX: 1.0+

MX: 4.2+

2 Uninstall Removes the User app with the specified Package Name from the device. If the requested app cannot be found or removed, an error is returned in the Result XML. Note- When an app is removed, data stored in sandbox areas owned by that app also are removed. If the app requiring such data is reinstalled, the data must be recreated.

OSX: 1.0+

MX: 4.1+

3 Upgrade Upgrades the User app contained within an .apk file in the specified path with the same Package Name on the device. When an app is upgraded, data associated with that app is maintained. If the requested app cannot be found, the selected app is installed on devices running Android 4.x KitKat or later. In devices running Android Jelly Bean, an Upgrade can replace any version of an app with any other version of the same app. In devices running Android 4.x KitKat or later, an Upgrade can replace only apps with a numerically greater version number.

OSX: 1.0+

MX: 4.1+

4 SetDefaultLauncher Sets a System or User app with the specified Package Name as the new default launcher. The specified app must already be installed on the device and generally should be designed to be a Android Launcher according to Android specifications. If no app with the specified Package Name is installed on the device, an error is returned in the Result XML document.

OSX: 1.3+

MX: 4.1+

5 EnableApplication Enables the System app with the specified Package Name to be launched. If the Package Name does not exist on the device, an error is returned in the Result XML document.

MX: 4.2+

Android API: 1+

6 DisableApplication Prevents the System app with the specified Package Name from being launched. If Package Name does not exist on the device, an error is returned in the Result XML document.

2 Only on Downgrade errors Reports an error and halts the Upgrade Action only if a Downgrade is detected.

MX: 11.3+

.apk Name

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.

IMPORTANT NOTES:

  • An .apk file can be used only to Install or Upgrade a User app or to Upgrade a System app.
    Any app being installed from an .apk file is by definition a User app since it was not built into the device.
  • For an Upgrade, the .apk file must be signed with the same developer certificate as the app it is intended to upgrade or an error will result.
  • A System app can be upgraded using only an .apk file produced by the same developer that produced the built-in System app.
  • A System app that has been upgraded is considered a User app, but will have the same permissions as the System app it replaced, allowing the new version to perform the same operations as the original app. If upgrades are removed from such an app, the app reverts to its original built-in version and is once again considered a System app.
  • Rules for "Split apk" Install/Upgrade Actions using App Bundles:
    • Can be performed only on Install or Upgrade Actions; Downgrade is not supported.
    • Must be packaged in .apks, .xapk or .zip file formats.
    • May contain ONLY .apk file(s) and the (optional) corresponding .obb APK Expansion Files.
    • A split .apk MUST contain only a SINGLE base .apk.
    • Package names and version code of the base .apk and all splits must be identical.
    • The base .apk and all splits must share the same signing key.
    • If .obb files are used, they must be named according to Google Play naming guidelines.
    • Split installations are supported on devices with MX 11.3 or later.

Parm Name: ProtectedListPackage

Requires:

  • OSX: 1.2+
  • MX: 4.2+

Access App Info

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.
