title: Android Honeycomb notification popup too frequently
body: <p>I am developing for Honeycomb and for days i am trying to solve this problem.
  I have an notification service without intent (don`t need one), the problem is that after every call for <em>displaymessage</em> function the notification pup-up each time, so i get 100 notifications. I would like it to popup only once and after that only change the text of percent. Similar to downloading from market progress bar and percentage. I have isolated the function and created new testing code but with no success. If you look at this from other angle, i wish to change the text on existing notification without creating new notification.
  Can you please help me?</p>
  
  <p>Here is the whole code (after the isolation):</p>
  
  <pre><code>package com.disp;
  
  
  import android.app.Activity;
  import android.app.Notification;
  import android.app.NotificationManager;
  import android.content.Context;
  import android.os.Bundle;
  import android.os.SystemClock;
  
  public class DispalyActivity extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
  
          for (int i = 0; i &lt; 100; i++) {
              SystemClock.sleep(300);
              displaymessage(""+i+"%");
  
          }
      }
  
      public void displaymessage(String string) {
          String ns = Context.NOTIFICATION_SERVICE;
          NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
          Notification notification = new Notification(R.drawable.ic_launcher, "Notification Service", System.currentTimeMillis());
          Context context = getApplicationContext();
          notification.setLatestEventInfo(context, "Downloading Content:", string, null);
          final int HELLO_ID = 2;
          mNotificationManager.notify(HELLO_ID, notification);
  
      }
  }
  </code></pre>
