[RK3288][Android7.1] 调试笔记 --- 横竖屏加载不同的开机动画

Platform: RK3288
OS: Android 7.1.2
Kernel: v4.4.143

需求：

Android系统项目定制开机动画，自定义的开机动画需保存在/system/media/bootanimation.zip，终端在横竖屏状态加载不同的bootanimation.zip，以实现在横竖屏的LOGO都能正常显示不拉伸。

解决：

1、制作横屏和竖屏的bootanimation.zip

方法1：

路径：/device/rockchip/rk3288/bootanimation

在源码里添加放置两个bootanimation.zip，举例命名为bootanimation_h.zip和bootanimation_v.zip分别代表横屏的LOGO和竖屏的LOGO；

路径：/device/rockchip/rk3288/rk3288.mk

编译时会将/device/rockchip/rk3288/bootanimation/的两个压缩包拷贝到system/media/目录下

PRODUCT_COPY_FILES += device/rockchip/rk3288/bootanimation/bootanimation_v.zip:system/media/bootanimation_v.zip
PRODUCT_COPY_FILES += device/rockchip/rk3288/bootanimation/bootanimation_h.zip:system/media/bootanimation_h.zip

方法2：

路径：out/target/product/rk3288/system/media

直接在此路径放置压缩包，打包时会自动存到系统/system/media/目录下

2、通过判断横竖屏执行不同的bootanimation
