EMDK For Android - 8.0

Overview

The ComponentMgr is used to configure the state and usage of subsystems such as Ethernet on the device. The state defines whether a subsystem is On (active) or Off (inactive). Usage enables or disables the subsystem and controls whether its state can be changed (turned On or Off) by the device user through the System Settings Menu or programmatically using the ComponentMgr. If an attempt is made to use the ComponentMgr to control the state of a subsystem for which usage is currently disabled, an error will be returned in the Result XML document.

Note: Not every device supports every subsystem. For example, some devices have no support for Ethernet. Attempts to use the ComponentMgr to control the state or usage of a subsystem that is not supported on a given device causes an error to be returned in the Result XML document.

Main Functionality

  • Turn Ethernet On or Off
  • Enable or Disable Ethernet Usage

Ethernet Usage

Controls whether the state of the Ethernet Option can be changed. If the usage of Ethernet is Disabled and then Enabled, the state of Ethernet, either On or Off, will be the same as it was before it was Disabled.

Parm Name: EthernetUsage

Option Name Description Note Requires
0 Do not change This value (or the absence of this parm from the XML) causes no change to Ethernet settings, any previously selected setting is retained.
