Data flow: Receiving configuration updates on an 

Android

 device

An action is taken in the management console that triggers a configuration update for an 

Android

 device.

Updates are applied in 

BlackBerry UEM

, and objects that must be shared with the device are identified.

The 

BlackBerry UEM Core

 contacts the 

BlackBerry Infrastructure

, through the 

BlackBerry Router

 or TCP proxy server, if installed, and the external firewall over port 3101.

The 

BlackBerry Infrastructure

 uses the FCM to notify 

Android

 devices that an update is pending. 

The GCM sends a notification to the 

BlackBerry UEM Client

 on the 

Android

 device to contact the 

BlackBerry UEM Core

.

The 

BlackBerry UEM Client

 contacts the 

BlackBerry UEM Core

, on port 3101 on the external firewall, to request any pending actions and commands that must be performed on the device.

The 

BlackBerry UEM Core

 replies, through the 

BlackBerry Infrastructure

 and 

BlackBerry Router

 or TCP proxy server, if installed, with the highest priority action.

The 

BlackBerry UEM Client

 inspects the response, schedules the command to be processed, and waits for the command to be run. The 

BlackBerry UEM Client

 sends a response to the 

BlackBerry UEM Core

, through the 

BlackBerry Infrastructure

, to update the command status. The status indicates whether the command ran successfully and provides an error message in the event of a failure.

If more actions or commands are pending for the device, the 

BlackBerry UEM Core

 replies, through the 

BlackBerry Infrastructure

, with the highest priority action. If no actions or commands are pending for the device, the 

BlackBerry UEM Core

 replies with an idle command.
