11 开机动画和铃声 CTS 测试新增要求如下
google 本身的动画so是包含这块逻辑处理的，但是不能播放 mp3 类型铃声，使用 mtk 框架那套是不完整的
需要我们自己修改一下
软重启相关介绍可以看官方
测试指令
adb shell svc power reboot userspace

分析过程
先到谷歌原始框架中看看是怎么处理软重启场景动画播放逻辑
frameworks\base\cmds\bootanimation\BootAnimation.cpp
void BootAnimation::findBootAnimationFile() {
.....
const bool playDarkAnim = android::base::GetIntProperty("ro.boot.theme", 0) == 1;
static const std::vector<std::string> bootFiles = {
APEX_BOOTANIMATION_FILE, playDarkAnim ? PRODUCT_BOOTANIMATION_DARK_FILE : PRODUCT_BOOTANIMATION_FILE,
OEM_BOOTANIMATION_FILE, SYSTEM_BOOTANIMATION_FILE
};
static const std::vector<std::string> shutdownFiles = {
PRODUCT_SHUTDOWNANIMATION_FILE, OEM_SHUTDOWNANIMATION_FILE, SYSTEM_SHUTDOWNANIMATION_FILE, ""
};
static const std::vector<std::string> userspaceRebootFiles = {
PRODUCT_USERSPACE_REBOOT_ANIMATION_FILE, OEM_USERSPACE_REBOOT_ANIMATION_FILE,
SYSTEM_USERSPACE_REBOOT_ANIMATION_FILE,
};
if (android::base::GetBoolProperty("sys.init.userspace_reboot.in_progress", false)) {
findBootAnimationFileInternal(userspaceRebootFiles);
} else if (mShuttingDown) {
findBootAnimationFileInternal(shutdownFiles);
} else {
findBootAnimationFileInternal(bootFiles);
}
}
sys.init.userspace_reboot.in_progress 这个值在执行软重启指令后会赋值
在 userspace-reboot-fs-remount 操作结束时，init 会启动 bootanim 服务。
此服务会按以下动画文件列出的顺序查找其是否存在，并播放找到的第一个动画：
/product/media/userspace-reboot.zip
/oem/media/userspace-reboot.zip
/system/media/userspace-reboot.zip
注意：动画文件必须遵循以下格式
如果未指定软重启的专用动画文件，bootanim 会显示默认的 android 动画。
经过搜索找到处理软重启指令入口，reboot.cpp
