}

Then. Add this class to the list of service class names that systemui boot up:

Change File Frameworks/base/packages/systemui/src/com/android/systemui/systemuiservice.java

Private final class<?>[] SERVICES = new class[] {
Com.android.systemui.recent.Recents.class,
Com.android.systemui.statusbar.SystemBars.class,
Com.android.systemui.usb.StorageNotification.class,
Com.android.systemui.power.PowerUI.class,
Com.android.systemui.media.RingtonePlayer.class,
Com.android.systemui.settings.SettingsUI.class,
Com.android.systemui.settings.UpdateUI.class,
Com.android.systemui.net.NetWorkWarningUI.class,
};

So far. Join Complete:
