Power Manager

Overview

The Power Manager (PowerMgr) allows an app to perform certain OS- and power-related actions on the device. These include rebooting or performing an OS update, resetting the device to a factory-fresh state or putting the device into Sleep mode. On some devices, such as the VC80x vehicle-mounted computer and similarly equipped Zebra devices, PowerMgr also can control device heaters and perform actions based on ignition status of vehicle-mounted computers and similarly equipped Zebra devices. PowerMgr performs only actions; it currently supports no queries other than to determine the version of the CSP that implements PowerMgr itself.

It's important to note that PowerMgr actions such as Reboot and Reset, once executed, prevent the execution of subsequent actions submitted by the Request XML document, including the submission of a Result XML to the application sending the original Request. Zebra therefore recommends using Condition Manager in conjunction with PowerMgr to ensure that appropriate conditions exist on a device before attempting to perform "risky" operations such as OS updates, the failure of which can render a device unusable, severely limited or otherwise in need of service.

  • Set the device to automatically turn on and/or off vehicle-mounted computers along with vehicle ignition switch
  • Set a delay (in minutes) for device auto-off

Sleep Mode

On Android devices, Sleep mode turns off the device display screen and places some subsystems into low-power states. Depending on device configuration settings, certain apps and/or subsystems such as Wi-Fi and Cellular might remain active.

Reboot

Rebooting an Android device generally causes only volatile information such as application state and transient data to be lost. Non-volatile data such as device settings and stored apps and data are preserved. A Reboot is sometimes referred to as a "Reset" or "Normal Reset," but is not to be confused with an Enterprise Reset or Factory Reset (explained below).

Note: The Reboot Action causes the device to immediately restart, preventing any subsequent Actions from executing, including the submission of a Result XML to the application sending the original request.

Enterprise Reset

Enterprise Reset is intended to return the device to an enterprise-defined default state, generally as determined by the contents of the /enterprise partition. On Zebra Android devices, an Enterprise Reset is the same as a Factory Reset except that the /enterprise partition is preserved. This action is supported only on Zebra devices running Android 4.4 KitKat and higher. On Zebra Android devices running Android Jelly Bean or lower, the same action could be performed using the "OS Update" action if a suitable OS Update .zip file was used.

Note: The Enterprise Reset Action causes the device to Reboot (into Recovery Mode), preventing any subsequent Actions from executing, including the submission of a Result XML to the application sending the original request.

BEST PRACTICE: Enterprise Reset should be triggered only through Power Manager and only with the Setup Wizard Bypass flag set to "true." Manually triggering Enterprise Reset without setting the bypass flag could leave the device in an unexpected state.

Factory Reset

The Factory Reset is intended to return the device to its factory-fresh condition with the exception of certain conditions related to its internal storage card(s) (see below). On Zebra Android devices, a Factory Reset erases all key partitions and storage cards containing /data, /cache, and /enterprise partitions. This action is supported only on Zebra devices running Android 4.4 KitKat and higher. On Zebra Android devices running Android Jelly Bean or lower, the same action could be performed using the "OS Update" Action if a suitable OS Update .zip file was used.

Note: This Action causes the device to Reboot (into Recovery Mode), preventing any subsequent Actions from executing, including the submission of a Result XML to the application sending the original request.

Resetting Storage Cards

A Factory Reset will erase a storage card if:

• The card was implemented within the /data or /enterprise partitions

A Factory Reset will NOT erase a storage card if:

• The card was implemented with its own dedicated partition
• The card is physically removable

Full Device Wipe

The Full Device Wipe is intended to return the device to its condition as it would have shipped from the factory with its current OS plus any subsequent OS update(s). On Zebra Android devices, a Full Device Wipe is the same as a Factory Reset plus the unconditional erasure of all storage cards. This action is supported only on Zebra devices running Android 4.4 KitKat and higher. On Zebra Android devices running Android Jelly Bean or lower, the same action could be performed using the "OS Update" Action if a suitable OS Update .zip file was used.

Note: This Action causes the device to Reboot (into Recovery Mode), preventing any subsequent Actions from executing, including the submission of a Result XML to the application sending the original request.

OS Update

The OS Update allows the device operating system to be replaced or patched using a specified OS Update Zip File or a text file containing a list of OS updates and/or patches. Depending on the contents of the file(s), this process also can be used to perform an OS Downgrade (on devices some), Enterprise Reset, Factory Reset or Full Device Wipe to facilitate the installation of the update or patch contained in the file(s).

Devices running Android 7.x Nougat and below support OS Update only. Devices with Android 8.x Oreo and later support Upgrade and Downgrade Actions and the Supress Reboot parameter.

Notes:

• The OS Update Action causes the device to Reboot (into Recovery Mode), which prevents execution of any subsequent Actions, including the submission of a Result XML to the application sending the original request.
• OS Update can be used to upgrade or downgrade Android 7.x Nougat and older.
• On devices running Android 8.x Oreo or later, the OS Update Action can only upgrade.

OS Upgrade/Downgrade

OS Upgrade (Oreo+)

Use the following basic steps to perform an OS Upgrade on devices running Oreo and higher. Steps might vary slightly depending on the device(s), the environment or other factors.

To perform an OS Upgrade:

1. Create a StageNow Profile with PowerMgr settings.
2. Push upgrade .zip file to internal storage (/storage/sdcard0) of the unit under test (UUT).
3. Set PowerMgr ResetAction as "10" (OS Upgrade) to perform an update of the UUT.
4. Enter "file-details" characteristic with location of the .zip file in UUT (see sample XML below).
5. Optionally, set SuppressReboot as False (unchecked).
   This step is optional because the OS Update Action automatically triggers a device reboot.
6. StageNow only: Generate a barcode that contains the Profile with these settings.
7. StageNow only: Launch StageNow and scan the barcode.
8. Verify that the UUT starts an update process and reboots after a successful OS Update (and Enterprise Reset if security patch is different).

Reset Action

Used to invoke an OS- or power-related action on the device.

WARNING: Read Overview section carefully for important information and device restrictions related to the use of Reset, OS Update, OS Upgrade and OS Downgrade Actions.

Note: Upload list (.upl) files are not supported on TC70/TC75 devices running Android 4.x KitKat.

Parm Name: ResetAction

OS Update 'Zip' File

Used to enter the path and filename of the file to be consumed when updating the device using a supported Action. The OS Update file must be the specific .zip file being applied, or a text file (with .upl extension) containing a list of patches (multiple .zip files) to be applied in the desired order from top to bottom as listed in the file.

For example, if the .zip files M99N0KXXVPUCP14500.zip and CFE-M99-L-N0-010101_G_00_02.zip are to be applied in that order, an OS Update text file should be created as follows:

//Contents of the "osupdate.upl" text file:

package:M99N0KXXVPUCP14500.zip
package:CFE-M99-L-N0-010101_G_00_02.zip

// Note the package files are preceded by the notation "package:" 

Update File Rules

• Device "Reset" commands are supported for use within a .upl file only on devices running Android 10. Other devices must execute all required reset(s) using Reset Actions in one or more StageNow Profile(s). See syntax, below.
• Zebra recommends matching case when entering file names to avoid case-sensitivity errors on some devices.
• Required file(s) must be on the device before a Reset Action is initiated.
• The .upl file and all referenced .zip files must be in the same device folder.
• The folder used for storing file(s) must be a supported location according to the Android Location/Device Location Rules below.
• Location rules and characteristics vary by device.
• The following devices do not support .upl files:
  • TC70 KitKat
  • TC75 KitKat

Device Reset Commands

Device "Reset" commands are supported for use within a .upl file only on devices running Android 10 and only using the syntax below.

// On devices running Android 10 (or later) the "osupdate.upl" text file can contain
// one or more Reset commands using the following syntax:

command:FactoryReset
command:EnterpriseReset

// See the Overview section for more information about resetting the device. 

Android File Location Rules

• Update file location must not be blocked by SdCardMgr or any other means.
• Removable media must be physically present. Storage partitions implemented on a removable medium such as a Micro SD Card must be inserted in the device when the Reset Action is initiated.
• The location must not be encrypted. A location that is encrypted cannot be used for OS Updates. For example, if Full Storage Card Encryption is enabled for a particular Storage Card, that card contains no suitable locations for OS Updates. Similarly, if an Encrypted File System was mounted on a Storage Card, that card also would be unsuitable for OS Updates.
• The update entity must have write permissions in the update file location.
• Emulated Storage Cards are not supported on Jelly Bean. Devices running KitKat and higher are not effected by this limitation.
• Adoptable Storage is not supported. Zebra devices by default do not implement the Android Adoptable Storage spec, which formats the SD Card for use with a single device. An Adoptable SD Card cannot be used to store update files.

Note: The path specified using this parameter would normally be the same as the path to which the file was written when it was transferred to the device. However, path names can sometimes appear to be different while ending at the same destination, and it's possible that some such paths will fail to initiate an OS Update when specified using this parameter. Therefore, Zebra recommends using paths in the following table when entering the OS Update file to the PowerMgr.

Device File Location Rules

Note: Zebra devices running Android Lollipop and Marshmallow might support update-file locations other than the location recommended in the table above. Other supported locations might include:

• /storage/sdcard0 (internal)
• /storage/sdcard1 (external)

However, support of such locations is subject to changes that are beyond Zebra's control. Zebra recommends testing any update procedure on a working device before the process is considered for mass deployment.

Parm value input rules:

• String from 1–255 characters containing full path and file name of OS Update .zip or .upl file

Note: Upload list (.upl) files are not supported on TC70/TC75 devices running Android KK

Setup Wizard Bypass

Controls whether to bypass the "Android device setup wizard" (also known as the "Welcome Screen") and the Zebra Setup Wizard (with Analytics data collection agent opt-out) following an Enterprise Reset initiated through PowerMgr. Applies only on devices with Google Mobile Services (GMS) and only when Enterprise Reset is initiated by PowerMgr.

Important: The bypass setting does not persist on the device following an Enterprise Reset. If SUW bypass is desired following an Enterprise Reset, this parameter must be included and set to "true" in the same Profile that is used to initiate the Enterprise Reset. The bypass flag was intended to be available as an option ONLY when Enterprise Reset is selected. However, MX 7.1 and 7.2 allow SUW bypass to be configurable regardless of the Enterprise Reset parameter setting. Once pushed to such devices, a bypass flag value of "true" will persist until an Enterprise Reset is executed or the flag is changed to "false" by a subsequent profile.

Note: Once running, the setup wizard can be exited on some devices by scanning a barcode. More info.
