DataWedge Configuration

106

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.

Example

Comments

This Data Capture API intent allows the scanner plug-in for the current Profile to be enabled or disabled. For

example, activity A launches and uses the Data Capture API intent to switch to ProfileA in which the scanner

plug-in is enabled, then at some point it uses the Data Capture API to disable the scanner plug-in. Activity B is

launched. In DataWedge, ProfileB is associated with activity B. DataWedge switches to ProfileB. When activity A

comes back to the foreground, in the

onResume method, activity A needs to use the Data Capture API intent to

switch back to ProfileA, then use the Data Capture API intent again to disable the scanner plug-in, to return back to

the state it was in.

Enumerate Scanners

Use the enumerateScanners API command to get a list of scanners available on the device.

$ adb logcat -s DWAPI

// define action and data strings

String scannerInputPlugin = "com.symbol.datawedge.api.ACTION_SCANNERINPUTPLUGIN";

String extraData = "com.symbol.datawedge.api.EXTRA_PARAMETER";

public void onResume() {

// create the intent

Intent i = new Intent();

// set the action to perform

i.setAction(scannerInputPlugin);

// add additional info

i.putExtra(extraData, "DISABLE_PLUGIN");

// send the intent to DataWedge

context.this.sendBroadcast(i);

}

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

the Profile.

The above assumes that ProfileA is not associated with any applications/activities, therefore when focus

switches back to activity A, DataWedge will not automatically switch to ProfileA therefore activity A must

switch back to ProfileA in its onResume method. Because DataWedge will automatically switch Profile

when an activity is paused, it is recommended that this API function be called from the onResume method

of the activity.
