Component Manager

EMDK For Android - 4.2

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 will support every subsystem. For example, some devices have no support for Ethernet. If you try to use the ComponentMgr to control the state or usage of a subsystem that is not supported on a given device, then an error will be returned in the Result XML document.

Main Functionality

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

Ethernet Usage

This parm allows you to control 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 Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no changes to whether the Ethernet can be used.

OSX: 4.4+

MX: 4.4+

1 Enable This value will cause the state of the Ethernet Option to be unlocked, allowing it to be changed, either by the device user or by the ComponentMgr.

OSX: 4.4+

MX: 4.4+

2 Disable This value will cause the state of the Ethernet Option to be locked, preventing it from being changed, either by the device user or by the ComponentMgr.

OSX: 4.4+

Ethernet State

This parm allows you to change the state of the Ethernet Option to On or Off.

Parm Name: EthernetState

Option Name Description Requires
0 Do not change This value (or the absence of this parm from the XML) will cause no changes to whether the Ethernet Option is turned On or Off.

OSX: 4.4+

MX: 4.4+

1 Turn on This value will cause the Ethernet Option to be turned On, thus allowing the use of an Ethernet connection on the device.

OSX: 4.4+

MX: 4.4+

2 Turn off This value will cause the Ethernet Option to be turned Off, thus disallowing the use of an Ethernet connection on the device.

OSX: 4.4+

MX: 4.4+
