Notification and Notificationmanager

1 String service = Notification; 2 notificationmanager nm = (notificationmanager) getsystemservice (service);

// Instantiate notification New Notification (); // Who knows the display icon, the icon will appear in the status bar int icon = N.icon = R.drawable.icon; // Set the display prompt message, String tickrttext = "Test Notification"; // Show Time long when == = when;
