2 applications OR Background application and foreground application can communicated through GlobalEventListener

  • Implemented the GlobalEventListener interface

  • Register for global event using the below line

    addGlobalEventListener(instance of class which implement the GlobalEventListener );

  • From background application post the global events (for other application) using the below line

    ApplicationManager.getApplicationManager().postGlobalEvent(MainWindow.GUID);

Note : postGlobalEvent methods having the 4 overloaded versions So you can pass addition info as well if require

  • Following method of GlobalEventListener interface method will listen the global event

    public void eventOccurred(long guid, int data0, int data1, Object object0, Object object1)

see the links for more details
