java - NotificationManager: cancel(id) DON'T work -

-

from service, show notification. have code:

    public final static int notification = 1;        public final static int notification2 = 2;  case notification2:     builder.setsmallicon(r.drawable.ic_action_about);                 builder.setcontenttitle(context.getstring(r.string.app_name));                 new thread(new runnable() {                     @override                     public void run() {                         // todo auto-generated method stub                         for(int i=0;i<10;i++) {                             builder.setcontentinfo(i+"/"+10);                             notificationmanager.notify(notification2, builder.build());                             try {                                 thread.sleep(1000);                             } catch (interruptedexception e) {                                 // todo auto-generated catch block                                 e.printstacktrace();                             }                         }                     }                                }).start();                  notificationmanager.cancel(notification2); break;

the code works fine, when thread finished notification remain. why? want cancel , cancel() doesn't work.

because start asynchronous thread displays notification, notificationmanager.cancel(notification2); called immediately. means notification not displayed yet, when cancelled it.

try move notificationmanager.cancel(notification2); run() method.
