将应用加入白名单

背景：
项目中需要把一个自己写的应用加入到android系统的/system/priv-app目录下面，在该应用的AndroidManifest.xml中添加权限

<uses-permission android:name="android.permission.REBOOT"
        tools:ignore="ProtectedPermissions" />

将该应用系统签名打包放入设备/system/priv-app目录下，重启设备，系统启动报错：

经过查找，参考链接https://blog.csdn.net/HongEnIT/article/details/124888610
手动修改方式：
修改下面文件：/system/etc/permissions/privapp-permissions-platform.xml，添加新增应用包名及权限，如下：

<!--xxx add start 20230526-->
	<privapp-permissions package="com.xxx.carstation">
        <permission name="android.permission.REBOOT" />
    </privapp-permissions>
<!--xxx add end 20230526-->

在android系统源码中修改：
修改文件：/home/ss/X9-work/buildsystem/android/frameworks/base/data/etc/privapp-permissions-platform.xml
同样添加新增应用包名及权限，如下：

<!--xxx add start 20230526-->
	<privapp-permissions package="com.xxx.carstation">
        <permission name="android.permission.REBOOT" />
    </privapp-permissions>
<!--xxx add end 20230526-->

编译系统程序，烧录到设备中。问题解决。
