Usage:

From Native to Javascript

Javascript

    console.log( "register didShow received!" );

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

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

From ANDROID to Javascript - Extra ANDROID features

Listen for global message

if( cordova.platformId === "android" ) {

    var listener = function( e ) {
      //log: didShow received! userInfo: {"data":"test"}
      console.log( "CONNECTIVITY_CHANGE: " + JSON.stringify(e)  );
    }
    var isGlobal = true
    window.broadcaster.addEventListener( 'android.net.conn.CONNECTIVITY_CHANGE', isGlobal, listener);
}

ANDROID

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

final Bundle child = new Bundle();
child.putString( "name", "joker");

final Bundle b = new Bundle();
b.putString( "data", "test");
b.putBoolean( "valid", true );
b.putBundle( "child", child );

intent.putExtras( b);

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

IOS

Objective-C

    NSDictionary * payload = @{
        @"data":@"test",
        @"valid": [NSNumber numberWithBool:YES],
        @"child": @{ @"name": @"joker" }
    };
    
    [[NSNotificationCenter defaultCenter] postNotificationName:@"TEST.EVENT"
                                                        object:nil
                                                      userInfo:payload];

Swift 5.x

  let payload:[String:Any] = [
          "data":"test",
          "valid": true,
          "child":[ "name": "joker" ]
      ]

  let nc = NotificationCenter.default
  nc.post(name:Notification.Name("didShow"), object: nil, userInfo: payload)

BROWSER

let event = new CustomEvent("didShow", { detail: { data:"test"} } );
document.dispatchEvent( event )

    console.log( "event fired!" );
    } );

Send a message with "flags" and "category"

if( cordova.platformId === "android" ) {

  // send a message with "flags" and "category"
  window.broadcaster.fireNativeEvent( "message", { extras:{ item:'test data' }, flags:0, category:'android.intent.category.INFO'}, function() {
    console.log( "event fired!" );
  });
}

Send a global message

if( cordova.platformId === "android" ) {

  // send a global message
  var isGlobal = true
  window.broadcaster.fireNativeEvent( "GLOBAL_ACTION", isGlobal, { item:'test data' }, function() {
    console.log( "event fired!" );
  });

}

Send a global message with "flags" and "category"

if( cordova.platformId === "android" ) {

  // send a global message with "flags" and "category"
  var isGlobal = true
  window.broadcaster.fireNativeEvent( "GLOBAL_ACTION", isGlobal, { extras:{ item:'test data' }, flags:0, category:'android.intent.category.INFO'}, 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"));
}
