Android 13 SystemUI 屏蔽导航栏；屏蔽锁屏；隐藏状态栏；禁止状态栏下拉；屏蔽Camera绿色图标；屏蔽原生音量条；屏蔽原生亮度条。

写在前面：本文给出Android 13 手机/平板原生SystemUI 一些实用的屏蔽补丁。

1、屏蔽导航栏

  导航栏屏蔽很简单，直接把创建导航栏的代码屏蔽即可。

代码路径:frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\phone\CentralSurfacesImpl.java
    // ================================================================================
    // Constructing the view
    // ================================================================================
    protected void makeStatusBarView(@Nullable RegisterStatusBarResult result) {
    	. . . . . .
    	. . . . . .
    	. . . . . .
    	//createNavigationBar(result);//注释这行代码即可
    	. . . . . .
    	. . . . . .
    	. . . . . .
	}

2、屏蔽锁屏
