      //log: didShow received! userInfo: {"data":"test"}
      console.log( "didShow received! userInfo: " + JSON.stringify(e)  );
    }

    window.broadcaster.addEventListener( "didShow", listener);

ANDROID

final Intent intent = new Intent("didShow");

Bundle b = new Bundle();
b.putString( "data", "test" );
intent.putExtras( b);

LocalBroadcastManager.getInstance(this).sendBroadcastSync(intent);

IOS

Objective-C

[[NSNotificationCenter defaultCenter] postNotificationName:@"didShow"
                                                    object:nil
                                                  userInfo:@{ @"data":@"test"}];

Swift

let nc = NSNotificationCenter.default
nc.post(name:"didShow", object: nil, userInfo: ["data":"test"])

BROWSER

document.dispatchEvent( event )

From Javascript to Native

  window.broadcaster.fireNativeEvent( "test.event", { item:'test data' }, function() {
    console.log( "event fired!" );
    } );

ANDROID

final BroadcastReceiver receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String data = intent.getExtras().getString("data");

        Log.d("CDVBroadcaster",
                String.format("Native event [%s] received with data [%s]", intent.getAction(), data));

    }
};

LocalBroadcastManager.getInstance(this)
            .registerReceiver(receiver, new IntentFilter("test.event"));
}

IOS

Objective-C

[[NSNotificationCenter defaultCenter] addObserverForName:@"test.event"
                                                  object:nil
                                                   queue:[NSOperationQueue mainQueue]
                                              usingBlock:^(NSNotification *notification) {
