Powerkey Manager

EMDK For Android - 5.0

Overview

The Power Key Manager (PowerKeyMgr) controls the functions displayed on the "Power Off" Menu, which appears after long-pressing the power key on the device. Depending on the device, such power-related functions can include Power off, Restart, Airplane Mode, Touch Panel, Safe Mode and other choices.

Zebra Android devices support a Screen Lock Timeout (controlled by the DevAdmin CSP), which controls how long the device screen must remain off before a screen lock will appear when the display screen is turned back on. When the Power Key is used to turn the device off (as opposed letting the screen time-out) a screen lock can be required when the display screen is turned back on, even if the timeout was not reached. The PowerKeyMgr can enable or disable this functionality and control whether the device user can change this functionality using the Android Settings panel.

Note: The PowerKeyMgr controls only those features supported on a given device. Some features disabled using PowerKeyMgr appear "grayed out" on the Power Off menu; others are hidden entirely.

Safe Mode Show/Hide

Controls whether the Safe Mode control is available in the Power Off Menu on devices that support this option. Safe Mode is typically used to perform troubleshooting operations that might be impeded by certain applications or services that would normally start when booting the device normally.
