SystemBarspublic class SystemBars extends com.android.systemui.SystemUI implements ServiceMonitor.Callbacks| Ensure a single status bar service implementation is running at all times.
The implementation either comes from a service component running in a remote process (defined
using a secure setting), else falls back to using the in-process implementation according
to the product config. |
