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.
$ 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);
