当我在 Android 4.0 (ICS) 中使用以下代码时，它不起作用:

     NotificationManager notificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.ic_launcher, "Testomg", System.currentTimeMillis() + 5000);

    Intent notificationIntent = new Intent(Intent.ACTION_VIEW);
    notificationIntent.setData(Uri.parse("market://details?id=com.karya.kot"));
    notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent intent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
    notification.setLatestEventInfo(getApplicationContext(), "Google Play", "Download app", intent);

    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

但它适用于较低版本的 Android。

对于Android ICS，我想使用Notification.Builder，但是对于较低版本我应该使用什么？

下面是我在 Android 2.2 及更高版本的任何版本上的完整工作代码

private static void generateNotification(Context context, String message) {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager)
                context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);

        String title = context.getString(R.string.app_name);

        Intent notificationIntent = new Intent(context, <nameofactivity>.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =
                PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;

        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);      

    }
