frameworks\base\cmds\bootanimation\BootAnimation.cpp添加开机铃声的核心功能分析和实现2.1 bootanimation_main.cpp开机动画处理分析frameworks\base\cmds\bootanimation\bootanimation_main.cpp
int main()
{
setpriority(PRIO_PROCESS, 0, ANDROID_PRIORITY_DISPLAY);
bool noBootAnimation bootAnimationDisabled();
ALOGI_IF(noBootAnimation, boot animation disabled);
if (!noBootAnimation) {spProcessState proc(ProcessState::self());ProcessState::self()-startThreadPool();// create the boot animation object (may take up to 200ms for 2MB zip)#ifdef BOOTANIMATION_EXT
spBootAnimation boot new BootAnimation(audioplay::createAnimationCallbacks(),true);

从代码中可以看到 是由BootAnimation来处理 开机铃声 frameworks\base\cmds\bootanimation\BootAnimation.cppstatic const char OEM_BOOTSOUND_FILE[] /oem/media/bootsound.mp3;

获取播放开机音乐路径PRODUCT_BOOTSOUND_FILE, OEM_BOOTSOUND_FILE, SYSTEM_BOOTSOUND_FILE 中的一个 所以系统默认的路径为SYSTEM_BOOTSOUND_FILE 即为 /system/media/bootsound.mp3 也就是说和开机动画放在同一个目录就可 persist.sys.bootanim.play_sound 属性的设置static const char PLAY_SOUND_PROP_NAME[] persist.sys.bootanim.play_sound;
bool BootAnimation::playSoundsAllowed() {
// Compatible with Android Things
// only system called will play sounds in system/media/
if (!mSystemCalled) {
return false;
}
// Read the system property to see if we should play the sound.
// If its not present, default to allowed.
if (!property_get_bool(PLAY_SOUND_PROP_NAME, 1)) {return false;
}// Dont play sounds if this is a reboot due to an error.
char bootreason[PROPERTY_VALUE_MAX];
if (property_get(BOOTREASON_PROP_NAME, bootreason, nullptr) 0) {for (const auto str : PLAY_SOUND_BOOTREASON_BLACKLIST) {if (strcasecmp(str.c_str(), bootreason) 0) {return false;}}
}
return true;}
是否允许播放中 会判断persist.sys.bootanim.play_sound 是否为1 如果不能播放 请查看这个值是否为1 开机铃声添加路径为 路径device/sprd/common/customer/system/media/bootsound.mp3 和开机动画放在同一个目录下就可以了
