Programming Notes; Overriding Trigger Key In An Application - Motorola MC40 Integrator Manual

MC40 Integrator Guide
Enterprise Folder
Internal storage contains the Enterprise folder (/enterprise). The Enterprise folder is persistent
and maintains data after an Enterprise reset. After an Enterprise Reset, DataWedge checks folder
/enterprise/device/settings/datawedge/enterprisereset/ for a configuration file,
datawedge.db or a profile file, dwprofile_x.db. If the file is found, it imports the file to replace any
existing configuration or profile.
A Factory Reset deletes all files in the Enterprise folder.
Auto Import
DataWedge supports remote deployment of a configuration to a device, using tools such as MSP. DataWedge
monitors the /enterprise/device/settings/datawedge/autoimport folder for the DataWedge
configuration file (datawedge.db) or a profile file (dwprofile_x.db). When DataWedge launches it checks
the folder. If a configuration or profile file is found, it imports the file to replace any existing configuration or
profile. Once the file has been imported it is deleted from the folder.
While DataWedge is running it receives a notification from the system that a file has been placed into the
/enterprise/device/settings/datawedge/autoimport folder. When this occurs, DataWedge
imports this new configuration or profile, replacing the existing one and delete the file. DataWedge begins using
the imported configuration immediately.
A Factory Reset deletes all files in the Enterprise folder.
It is strongly recommended that the user exits DataWedge before remotely deploying any configuration or
profile. It is required that the file permissions are set to 666.

4.10 Programming Notes

The following paragraphs provide specific programming information when using DataWedge.

4.10.1 Overriding Trigger Key in an Application

To override the trigger key in an application, create a profile for the application that disables the Barcode input.
In the application, use standard APIs, such as onKeyDown() to listen for the KEYCODE_BUTTON_L1 and
KEYCODE_BUTTON_R1 presses.
