body: <p>Now in android i put this code in one activity to show notification when a button pressed.</p>
  
  <pre><code>static int notificationCount = 0;
  </code></pre>
  
  <p>then</p>
  
  <pre><code> btnNotification.setOnClickListener(
              new View.OnClickListener() {
                  @Override
                  public void onClick(View v) {
  
                      Intent notificationIntent = new Intent(AlertsActivity.this,NotificationActivitty.class);
                      PendingIntent pIntent = PendingIntent.getActivity(AlertsActivity.this,notificationCount,notificationIntent,Intent.FLAG_ACTIVITY_NEW_TASK);
  
                      // Construct the notification
                      Notification.Builder nBuilder = new Notification.Builder(AlertsActivity.this);
                      nBuilder.setContentTitle("You Have a notification!");
                      nBuilder.setContentText("See Your Notification");
                      nBuilder.setSmallIcon(android.R.drawable.btn_star);
                      nBuilder.setContentIntent(pIntent);
                     nBuilder.addAction(android.R.drawable.stat_notify_call_mute, "go to", pIntent); // from icecream sandwatch - required api 16
  
                      // Build the notification
                      Notification noti = nBuilder.build(); // required api 16
  
                      //Send it to manager
                          NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                          manager.notify(notificationCount++,noti);
                  }
              }
      );
  </code></pre>
  
  <p>From Notification manager, Any notification that i clicked on it, it will redirect me to another activity (NotificationActivity)</p>
  
  <p>Now i put this code to clear the notification but it only clear the notification with id 0 so how can i clear the current pressed notification</p>
  
  <pre><code>public class NotificationActivitty  extends Activity{
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_notification);
  
      NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
      manager.cancel(0);
      // manager.cancelAll(); // Cancel all notifications for this app. from manager
  
  }
  </code></pre>
  
  <p>I need to clear the notification by it's id if it's possible.</p>
