[RK3399] [Android 7.1] 添加系统root权限

1.添加开机启动服务

rk3399/device/rockchip/common$ git diff init.rockchip.rc diff --git a/init.rockchip.rc b/init.rockchip.rc index a0ade29..b202580 100755 --- a/init.rockchip.rc +++ b/init.rockchip.rc +#lance root +service daemonsu /system/xbin/daemonsu --auto-daemon + class main + seclabel u:r:su:s0 + +on property:sys.boot_completed=1 + start daemonsu rk3399/device/rockchip/common$ git diff sepolicy/file_contexts diff --git a/sepolicy/file_contexts b/sepolicy/file_contexts index 728d4bc..0f45c30 100755 --- a/sepolicy/file_contexts +++ b/sepolicy/file_contexts +#myshell +/system/xbin/daemonsu u:object_r:shell_exec:s0

2.新建root目录，将压缩包中arm64里面相应文件拷贝过来 libsupol.so    su    supolicy

3.device.mk中添加拷贝工作

rk3399/device/rockchip/rk3399$ git diff device.mk diff --git a/device.mk b/device.mk --- a/device.mk +++ b/device.mk +#copy root +PRODUCT_COPY_FILES += \ + $(LOCAL_PATH)/root/libsupol.so:system/lib64/libsupol.so \ + $(LOCAL_PATH)/root/su:system/xbin/su \ + $(LOCAL_PATH)/root/su:system/xbin/daemonsu \ + $(LOCAL_PATH)/root/supolicy:system/xbin/supolicy

4.编译烧录安装apk测试，

注： 如果不行先检查服务是否开启，    dmesg | grep daemonsu 打开su apk，会提示更新二进制文件，点击取消。 注意：supersu不要更新二进制，否则会造成无法开机。
