google 默认开机动画代码在framework/base/cmds/bootanimation
MTK 开机动画代码在vendor/mediatek/proprietary/operator/framework/bootanimation/MtkBootanimation
一、启用 MtkBootanimation，编译 libmtkbootanimation
关闭 bootanimation，打开 mtkbootanimation
deleted: frameworks/base/cmds/bootanimation/Android.bp add frameworks/base/cmds/bootanimation/Android.bp_disable deleted: vendor/mediatek/proprietary/operator/frameworks/bootanimation/Android_disable.mk add vendor/mediatek/proprietary/operator/frameworks/bootanimation/Android.mk deleted: vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/Android_disable.mk add vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/Android.mk
配置编译 libmtkbootanimation
device/mediatek/$(platform_name)/device.mk
+++ b/alps/device/mediatek/mt6765/device.mk @@ -62,6 +62,8 @@ endif endif endif +PRODUCT_PACKAGES += mtkbootanimation +PRODUCT_PACKAGES += libmtkbootanimation #GPU collection PRODUCT_PACKAGES += libI420colorconvert
二、修改 MtkBootanimation mk 文件
vendor/mediatek/proprietary/operator/frameworks/bootanimation/Android.mk
修改 cxp_support := yes，通过打印 MSSI_MTK_CARRIEREXPRESS_PACK 不存在，
默认 cxp_support 为 no，所以不编译 MtkBootanimation/Android.mk
vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/Android.mk
增加 include $(BUILD_EXECUTABLE) 结尾，增加 include $(BUILD_SHARED_LIBRARY) 结尾，lib 配置中
增加
LOCAL_CFLAGS += -DMTK_TER_SERVICE
LOCAL_CPPFLAGS += -DMTK_TER_SERVICE
LOCAL_SHARED_LIBRARIES += libterservice
LOCAL_C_INCLUDES += $(MTK_PATH_SOURCE)/hardware/terservice/include/

三、BootAnimation.cpp 排错
vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/BootAnimation.cpp
错误1、 use of undeclared identifier ITerService
解决 mk中导入 libterservice，cpp 中引入 #include “ITerService.h”
错误2、 use of undeclared identifier BootanimFileName
解决 BootAnimation.cpp 增加 char BootanimFileName[PROPERTY_VALUE_MAX]; 定义
错误3、 ISurfaceComposer 不存在的构造函数
解决 sp dtoken(SurfaceComposerClient::getInternalDisplayToken());

四、其它
第一次开机没有铃声
1.frameworks/av/media/libaudioclient/AudioTrack.cpp
#endif + if(!strcmp(mAttributes.tags,"BootAnimationAudioTrack")) { + ALOGD("mAttributes.tags = BootAnimationAudioTrack"); + strcpy(input.attr.tags, "BootAnimationAudioTrack"); + }else{ + strcpy(input.attr.tags, ""); + } + input.flags = mFlags; input.frameCount = mReqFrameCount; input.notificationFrameCount = mNotificationFramesReq;

关机有关机动画，重启无关机动画
Default设计，关机过程会有一个delayForPlayAnimation，但是重启（除了恢复出产设置）不会，
由于重启本身就牵涉到时间上的连续行，不会有任何delay。
修改方案：
vendor\mediatek\proprietary\frameworks\base\services\core\java\com\mediatek\server\MtkShutdownThread.java
贵司只需要在MtkShutdownThread.java的
public static void rebootOrShutdown(boolean reboot, String reason) {
里面将如下if判断去掉：
// added for Shutdown animation private void shutdownAnimationService() { if(isCustBootAnim()!= ANIMATION_MODE) { return; } /* M: fix shutdown animation timing issue */ Log.i(TAG, "set service.shutanim.running to 1"); SystemProperties.set("service.shutanim.running", "1"); /*M: play animation*/ /*if ((mReboot == true && mReason != null && mReason.equals("recovery")) || (mReboot == false)) {*/ delayForPlayAnimation(); //} } 只保留 delayForPlayAnimation(); 只要reboot都做delay
开关机流程
1、开关机动画的动作会生成一个native 可执行文件/system/bin/mtkbootanimation
开机情况下， adb shell 进入 /system/bin/ 直接执行 mtkbootanimation 可查看开机动画和开机音乐
2、通过init.rc配置成Service
service bootanim /system/bin/mtkbootanimation class core animation user graphics group graphics audio disabled oneshot writepid /dev/stune/top-app/tasks # MTK add service banim_shutmp3 /system/bin/mtkbootanimation shut mp3 class core animation user graphics group graphics audio disabled oneshot writepid /dev/stune/top-app/tasks service banim_shutnomp3 /system/bin/mtkbootanimation shut nomp3 class core animation user graphics group graphics audio disabled oneshot writepid /dev/stune/top-app/tasks
3、开机时执行
frameworks/native/services/surfaceflinger/SurfaceFlinger.cpp
frameworks/native/services/surfaceflinger/StartPropertySetThread.cpp
SurfaceFlinger：：startBootAnim -->StartPropertySetThread::threadLoop // Clear BootAnimation exit flag property_set("service.bootanim.exit", "0"); // Start BootAnimation if not started property_set("ctl.start", "bootanim");
4、关机时执行
/vendor/mediatek/proprietary/frameworks/base/services/core/java/com/mediatek/server/MtkShutdownThread.java
private static void startBootAnimation() { Log.i(TAG, "Set 'service.bootanim.exit' = 0)."); SystemProperties.set("service.bootanim.exit", "0"); if (bPlayaudio) { SystemProperties.set("ctl.start", "banim_shutmp3"); Log.i(TAG, "bootanim:shut mp3"); } else { SystemProperties.set("ctl.start", "banim_shutnomp3"); Log.i(TAG, "bootanim:shut nomp3"); } }
5、开机动画逻辑入口
bootanimation_main.cpp
int main(int argc, char** argv) C++语言都是从main开始执行
sp boot = new BootAnimation(new AudioAnimationCallbacks(),setBoot,sePaly,setRotated);
