title: Android PendingIntent for foreGround Service
body: <p>I am still thoroughly confused by starting a service in the foreground.</p>
  
  <p>Currently: I have an activity that starts a service in the background to perform stats on sensor data+gps data. It keeps getting killed, so I started it in the foreground. Works fine. 
  However when I touch on the notification icon in the status bar it seems to start a new activity (which I did state in the Pending Intent).</p>
  
  <p>So in a nutshell I am still confused with the whole thing. 
  I would like an activity to start a service in the foreground, and when you click on the notification bar it brings the existing activity that started the service to the front. </p>
  
  <p>Here is some code within the activity (currently set PendingIntent to null):</p>
  
  <pre><code>private ServiceConnection mConnection = new ServiceConnection() {
       public void onServiceConnected(ComponentName className, IBinder service) {
          // This is called when the connection with the service has been
          // established, giving us the service object we can use to
          // interact with the service. Because we have bound to a explicit
          // service that we know is running in our own process, we can
          // cast its IBinder to a concrete class and directly access it.
  
          cycleDataService = ((CycleDataProService.LocalBinder) service)
                  .getService();
          //Todo the notification bullshaite here...
          String ns = Context.NOTIFICATION_SERVICE;
          NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
          int icon = R.drawable.icon;
          CharSequence tickerText = "Hello";
          long when = System.currentTimeMillis();
          Notification notification = new Notification(icon, tickerText, when);
          Context context = getApplicationContext();
          CharSequence contentTitle = "My notification";
          CharSequence contentText = "Hello World!";          
          //Intent notificationIntent = new Intent(cycleDataService, CycleDataProService.class);
          //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, myOwnIntent, PendingIntent.FLAG_UPDATE_CURRENT);
          PendingIntent pi = PendingIntent.getActivity(context, 0, null, 0);
  
          //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, , 0);
          notification.setLatestEventInfo(context, contentTitle, contentText, pi);
          mNotificationManager.notify(HELLO_ID, notification);
          cycleDataService.startForeground(HELLO_ID, notification);
          /*cycleDataService.startService(new Intent(cycleDataService,
                  CycleDataProService.class));*/
          serviceIsRunning = true;
          // Tell the user about this for our demo.
          // Toast.makeText(Binding.this, R.string.local_service_connected,
          // Toast.LENGTH_SHORT).show();
      }
  </code></pre>
