    3. FACTORY_TEST_LOW_LEVEL
    4. FACTORY_TEST_HIGH_LEVEL

boolean disableStorage = SystemProperties.getBoolean("config.disable_storage", false); boolean disableMedia = SystemProperties.getBoolean("config.disable_media", false); boolean disableBluetooth = SystemProperties.getBoolean("config.disable_bluetooth", false); boolean disableTelephony = SystemProperties.getBoolean("config.disable_telephony", false); boolean disableLocation = SystemProperties.getBoolean("config.disable_location", false); boolean disableSystemUI = SystemProperties.getBoolean("config.disable_systemui", false); boolean disableNonCoreServices = SystemProperties.getBoolean("config.disable_noncore", false); boolean disableNetwork = SystemProperties.getBoolean("config.disable_network", false);

流程

1. System.loadLibrary("android_servers")（加载lib android_servers库）
2. nativeInit
   1. 初始化native服务
3. ServerThread thr = new ServerThread()
4. thr.initAndLoop()
   1. new HandlerThread("WindowManager")
   2. installer = new Installer
   3. installer.ping()
   4. AttributeCache.init
   5. display.waitForDefaultDisplay
   6. firstBoot = pm.isFirstBoot
   7. ActivityManagerService.setSystemProcess
   8. ActivityManagerService.installSystemProviders
   9. Watchdog.getInstance().init
   10. Watchdog.getInstance().addThread(wmHandler, "WindowManager thread")
   11. ActivityManagerService.self().setWindowManager
   12. inputManager.setWindowManagerCallbacks(wm.getInputMonitor())
   13. display.setWindowManager
   14. display.setInputManager
   15. wm.displayReady
   16. ActivityManagerNative.getDefault().showBootMessage
   17. mountService.waitForAsecScan
   18. contentService.systemReady
   19. dock = new DockObserver
   20. inputManager.setWiredAccessoryCallbacks(new WiredAccessoryManager)
   21. wm.detectSafeMode
       1. ActivityManagerService.self().enterSafeMode
       2. VMRuntime.getRuntime().disableJitCompilation
   22. 调用服务的systemReady
   23. 调用服务的systemRunning
   24. Looper.loop
