Android Notification Monitor system clears the notification bar method

Write a notification notification tool class, which contains the listener system to clear the notification bar method, focus on bold italic part:

public class Notifier {
private static final String TAG = Notifier.class.getSimpleName ();
private static Notifier instance;
Private Context Mcontext;


private static final int notification_id_1 = 0;

private static final int notification_id_4 = 3;
private static final int notification_id_5 = 4;
private static final int notification_id_6 = 5;
private static final int notification_id_7 = 6;
private static final int notification_id_8 = 7;


public static Notifier getinstance (context context) {
if (instance = = null) {
Instance = new Notifier (context);
}
return instance;

}

}
