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

Sample code to retrieve the result of the array of supported triggers:

private BroadcastReceiver broadcastReceiverTriggers = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if (intent.hasExtra("com.symbol.datawedge.api.RESULT_ENUMERATE_TRIGGERS")) {

            String[] triggerList = extras.
                    getStringArray("com.symbol.datawedge.api.RESULT_ENUMERATE_TRIGGERS");
            List<String> arrTriggerList = Arrays.asList(triggerList);
            String strTriggers = "Trigger List: <br>";
            for (String trigger : arrTriggerList) {
                strTriggers += trigger + "<br>";
            }
            //Log.d(TAG, strTriggers);
        }
