send message in a localService

Question

Hi,

I would like to know if it's okay to do the follwing in a localservice:

public class theApp extends Application {  
     public static Handler m_msgHandler;  
} 

public class mainActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        theApp.m_msgHandler = m_msgHandler;
        ::::
    }

    private final Handler m_msgHandler = new Handler() {
        ::::
    }

    // Create the service somewhere in activity...

};


// Localservice  
public class CommunicationService extends Service {  

// Create a thread when the service starts....
//
// ...and if the connection breaks for some reason  
     theApp.m_msgHandler.obtainMessage(theApp.WIFI_STATE_CHANGE, SMSWiFi.STATE_NONE, 0).sendToTarget();

}

It seems to work fine, but I'm not sure this is the proper way to send the message to the activity.

Thanks,

Nicholas
