DataWedge

Error messages will be logged for invalid actions and parameters.

Example

Comments

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

activity A launches and uses the intent API 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 intent API to switch back to ProfileA, then use

the intent API again to disable the scanner plug-in, to return back to the state it was in.

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 thi

s API function be called from the onResume method of the activity.

Enumerate Scanners

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

Function Prototype

$ 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.sendBroadcast(i);

}

Intent i = new Intent();

i.setAction("com.symbol.datawedge.api.ACTION");

i.putExtra("com.symbol.datawedge.api.ENUMERATE_SCANNERS", "");
