title: Starting and stopping a notification from broadcast receiver
body: <p>I'm trying to start a status bar notification from a broadcast receiver and then stop it from another broadcast receiver but I'm having issues. I would like to start the notification in the status bar when usb is connected and then when usb is disconnected I would like to stop it I have the two receivers set up and working just struggling with starting and stopping one from a receiver here is the code I have currently</p>
  
  <p>My only error with my code is the <code>myNotificationManager = (NotificationManager) getSystemService(context.NOTIFICATION_SERVICE);</code> line the error just says getSystemService is undefined and it wants to make the method which I guess means that the receiver doesn't have support for that method like an activity would so what should I do to create and stop a notification from receivers thank you for any help</p>
  
  <pre><code>public class USBConnect extends BroadcastReceiver {
  
  public NotificationManager myNotificationManager;
  public static final int NOTIFICATION_ID = 1;
  
  @Override
  public void onReceive(Context context, Intent intent) {
  
      myNotificationManager = (NotificationManager) getSystemService(context.NOTIFICATION_SERVICE);
  
        CharSequence NotificationTicket = "USB Connected!";
        CharSequence NotificationTitle = "USB Connected!";
        CharSequence NotificationContent = "USB is Connected!";
  
        Notification notification = new Notification(R.drawable.usbicon, NotificationTicket, 0);
        Intent notificationIntent = new Intent(context, MyClass.class);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, NotificationTitle, NotificationContent, contentIntent);
        notification.flags |= Notification.FLAG_ONGOING_EVENT;
        myNotificationManager.notify(NOTIFICATION_ID, notification);
        }
  }
  </code></pre>
  
  <p><strong>And then the receiver for when it disconnects this I believe is fine and should work I think my problem is only in the USBConnect class</strong></p>
  
  <pre><code>public class USBDisCon extends BroadcastReceiver {
  
  @Override
  public void onReceive(Context context, Intent intent) {
      NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); 
      notificationManager.cancel(USBConnect.NOTIFICATION_ID);
      }
  }
  </code></pre>
