APP 、文件编译不生效问题
android 为惰性编译，直接替换后编译，一些APP、文件不一定编译到镜像中
可以通过如下其中一种方式解决
make installclean
rm out/target/product/apollo-p2/xxx/xxx
编译的条件发生变化（比如文件名、APK名）
默认屏幕方向
修改默认显示方向
触控修改参考如下，注意选择对应屏幕的设备树文件
旋转功能
支持使用adb命令进行旋转
// 0
adb shell settings put system user_rotation 0
// 90°
adb shell settings put system user_rotation 1
// 180°
adb shell settings put system user_rotation 2
// 270°
adb shell settings put system user_rotation 3
