答案对人有帮助，有参考价值 0 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 diff --git a/cmds/bootanimation/BootAnimation.cpp b/cmds/bootanimation/BootAnimation.cpp index 24c8fa4..86bb671 100755 --- a/cmds/bootanimation/BootAnimation.cpp +++ b/cmds/bootanimation/BootAnimation.cpp @@ -64,13 +64,17 @@ namespace android { +#define CONFIG_DATA_FILES_PLAYING static const char OEM_BOOTANIMATION_FILE[] = "/oem/media/bootanimation.zip";
