We can hide StatusBar, settiing of "config.disable_systemui" .

https://android.googlesource.com/platform/frameworks/base/+/android-4.4_r1/services/java/com/android/server/SystemServer.java

        boolean disableSystemUI = SystemProperties.getBoolean("config.disable_systemui", false);

            if (!disableSystemUI) {
                try {
                    Slog.i(TAG, "Status Bar");
                    statusBar = new StatusBarManagerService(context, wm);
                    ServiceManager.addService(Context.STATUS_BAR_SERVICE, statusBar);
                } catch (Throwable e) {
                    reportWtf("starting StatusBarManagerService", e);

About AppOps in Android 4.3

Android 4.3 added "AppOps" whitch is like permission manager.

Points

added AppOpsManager, AppOpsService in the frameworks(Java Layer).
If you would like to use "AppOps", you can called getSystemService(Context.LAYOUT_INFLATER_SERVICE).
Each "Service" in frameworks decide to run operation, by obtaining a setting from the AppOpsService,

If you want to know more info, you should do grep "AppOpsManager.MODE_ALLOWED / MODE_IGNORED" in AOSP.

Create "AppOpsService" instance

AppOpsService is created in ActivityManagerService's constructor.

    private ActivityManagerService() {
        File systemDir = new File(dataDir, "system");
            :
        mAppOpsService = new AppOpsService(new File(systemDir, "appops.xml"));
            :
    }

Setting data of AppOpsManager

Setting data of AppOps is saved to xml file. Xml file is named "appops.xml". It is saved under the System directory.

public class AppOpsService extends IAppOpsService.Stub {
    public AppOpsService(File storagePath) {
        mFile = new AtomicFile(storagePath);
        mHandler = new Handler();
        readState();
    }

    void readState() {

    }
    void writeState() {

    }
}

Ckeck it

You should check many source in AOPS(android-4.3_r2.1).

Settings application

- AppOpsDetails.java
