Notification on Android

I'm trying to send a notification via Android but it isn't working properly.

Here is my java code:

 public class MainActivity extends UnityPlayerNativeActivity {

 private static Context context;

 private static Notification mNotification;

 private static NotificationManager mNotificationManager;
 
 
 @Override
 protected void onStart() {
     // TODO Auto-generated method stub
     super.onStart();
     context = this;
 }
 
 @Override
 protected void onResume() {
     // TODO Auto-generated method stub
     super.onResume();
     context = this;
 }

 public static String GetString() {

     return "java: hello";
 }
 
 public static void NotifyUser()
 {
     Log.d("yoob", "NotifyUser");
     Log.d("yoob", "Start");
     Resources res = context.getResources();
     int icon = res.getIdentifier("yoobsicon", "drawable", context.getPackageName());
 
     
     NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
             context).setSmallIcon(icon)
             .setContentTitle("Yoob diz:")
             .setContentText("Fome da mizera!");
     mNotification = mBuilder.build();
     Log.d("yoob", "middle");
     mNotificationManager = (NotificationManager) context
             .getSystemService(Context.NOTIFICATION_SERVICE);
     mNotificationManager.notify(123, mNotification);
     Log.d("yoob", "end");
     

 }

}

And here's my Unity code:

 using UnityEngine;
 using System.Collections;
 
 public class NumberExample : MonoBehaviour {
 
     public string message = "mensagem";
 
     public TextMesh textMesh;
 
     private int count = 0;
 
     #if UNITY_ANDROID && !UNITY_EDITOR
     AndroidJavaClass pluginPlugAndPlay;
     #endif
     
     void Start () 
     {
         #if UNITY_ANDROID && !UNITY_EDITOR
         AndroidJNI.AttachCurrentThread();
         pluginPlugAndPlay = new AndroidJavaClass("com.cesar.yoobs.MainActivity");
         #endif
 
         //textMesh.text = message;
     }
     
     void Update()
     {
         #if UNITY_ANDROID && !UNITY_EDITOR
         message   = pluginPlugAndPlay.CallStatic<string>("GetString");
         count++;
         if(count == 100) pluginPlugAndPlay.CallStatic("NotifyUser");
         #endif
         message = message + " " + count;
         textMesh.text = message;
 
 
     }
 
 }

If I build my java code directly to android it works fine and I get the proper notification. On Eclipse I get a nullPointerException which I think it has to do with him not finding the icon when on Unity. I have everything set in Plugins/Android/res as I've seen other people mentioning here. Is there anything else I should be doing?

Thanks in advance.
