Android Q MTK平臺開關機鈴聲

google 默認開機動畫代碼在framework/base/cmds/bootanimation

MTK 開機動畫代碼在vendor/mediatek/proprietary/operator/framework/bootanimation/MtkBootanimation

一、啓用 MtkBootanimation，編譯 libmtkbootanimation

關閉 bootanimation，打開 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

配置編譯 libmtkbootanimation

二、修改 MtkBootanimation mk 文件

vendor/mediatek/proprietary/operator/frameworks/bootanimation/Android.mk

修改 cxp_support := yes，通過打印 MSSI_MTK_CARRIEREXPRESS_PACK 不存在，

默認 cxp_support 爲 no，所以不編譯 MtkBootanimation/Android.mk

vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/Android.mk

增加 include $(BUILD_EXECUTABLE) 結尾，增加 include $(BUILD_SHARED_LIBRARY) 結尾，lib 配置中

三、BootAnimation.cpp 排錯

vendor/mediatek/proprietary/operator/frameworks/bootanimation/MtkBootanimation/BootAnimation.cpp

錯誤1、 use of undeclared identifier ITerService

解決 mk中導入 libterservice，cpp 中引入 #include “ITerService.h”

錯誤2、 use of undeclared identifier BootanimFileName

解決 BootAnimation.cpp 增加 char BootanimFileName[PROPERTY_VALUE_MAX]; 定義

錯誤3、 ISurfaceComposer 不存在的構造函數

解決 sp dtoken(SurfaceComposerClient::getInternalDisplayToken());

關機有關機動畫，重啓無關機動畫

Default設計，關機過程會有一個delayForPlayAnimation，但是重啓（除了恢復出產設置）不會，

由於重啓本身就牽涉到時間上的連續行，不會有任何delay。

修改方案：

貴司只需要在shutdownThread.java的

public static void rebootOrShutdown(boolean reboot, String reason) {

裏面將如下if判斷去掉：

if ( (reason != null) && reason.equals("recovery") ) {

                delayForPlayAnimation();

            }

只保留

delayForPlayAnimation();

只要reboot都做delay

開關機流程

1、開關機動畫的動作會生成一個native 可執行文件/system/bin/mtkbootanimation

開機情況下， adb shell 進入 /system/bin/ 直接執行 mtkbootanimation 可查看開機動畫和開機音樂

2、通過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、開機時執行

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、關機時執行

/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、開機動畫邏輯入口

bootanimation_main.cpp

int main(int argc, char** argv) C++語言都是從main開始執行

sp boot = new BootAnimation(new AudioAnimationCallbacks(),setBoot,sePaly,setRotated);
