Android: remove notification from notification bar

I have created an application and with an event I manage to add notification in android notification bar. Now I need sample how to remove that notification from notification bar on an event ??

You can try this quick code

public static void cancelNotification(Context ctx, int notifyId) {
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
    nMgr.cancel(notifyId);
}

This is quite simple. You have to call cancel or cancelAll on your NotificationManager. The parameter of the cancel method is the ID of the notification that should be canceled.

See the API: http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)

You can also call cancelAll on the notification manager, so you don't even have to worry about the notification ids.

NotificationManager notifManager= (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notifManager.cancelAll();

EDIT : I was downvoted so maybe I should specify that this will only remove the notification from your application.
