Scanner Input Plugin

The ScannerInputPlugin API command can be used to enable/disable the scanner plug-in being used by the

currently active Profile. Disabling the scanner plug-in effectively disables scanning in that Profile, regardless of

whether the Profile is associated or unassociated. Valid only when Barcode Input is enabled in the active Profile.

Function Prototype

Parameters

action: String "com.symbol.datawedge.api.ACTION_SCANNERINPUTPLUGIN"

extra_data: String "com.symbol.datawedge.api.EXTRA_PARAMETER"

<parameter>: The parameter as a string, using either of the following:

• "ENABLE_PLUGIN" - enables the plug-in

• "DISABLE_PLUGIN" - disables the plug-in

Return Values

None.

Error and debug messages will be logged to the Android logging system which then can be viewed and filtered by

the logcat command. You can use logcat from an ADB shell to view the log messages, e.g.

Error messages will be logged for invalid actions and parameters.

Intent sendIntent = new Intent();

sendIntent.setAction(“com.symbol.emdk.datawedge.api.ACTION_SOFTSCANTRIGGER”);

sendIntent.putExtra(“com.symbol.emdk.datawedge.api.EXTRA_PARAMETER”,

“TOGGLE_SCANNING”);

sendBroadcast(sendIntent);

NOTE Use of this API changes only the runtime status of the scanner; it does not make persistent changes to the

Profile.

Intent i = new Intent();

i.setAction(ACTION);

i.putExtra(EXTRA_DATA, "<parameter>");

$ adb logcat -s DWAPI
