这个方法只适合有内置存储的情况，至于和平分区的不在考虑之列

1 在vendor/sprd下新建一个文件夹built_in_video 里边放置要内置的视频文件及copy脚步

脚步如下:internal_media.mk

LOCAL_PATH:= vendor/sprd/built_in_video

PRODUCT_COPY_FILES += \
    $(LOCAL_PATH)/media/Girs_Gee_0.mp4:system/preloadvideo/Girs_Gee_0.mp4

把这个internal_media.mk include到主mk中

include vendor/sprd/built_in_video/internal_media.mk

2  在vendor/sprd/open-source/tools新建文件夹preloadvideo里边放置加载内置U盘后把system/preloadvideo/Girs文件复制到内置U盘中

Android.mk如下

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := preloadvideo.sh
LOCAL_MODULE_CLASS := EXECUTABLES
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES)
LOCAL_SRC_FILES := preloadvideo.sh
include $(BUILD_PREBUILT)

#!/system/bin/sh
PRELOAD_DEST=/storage/sdcard0/Movies
PRELOAD_FLAG=${PRELOAD_DEST}/preloadvideo
PRELOAD_SOURCE=/system/preloadvideo

if [ ! -d ${PRELOAD_DEST} ]
then
    mkdir -p ${PRELOAD_DEST}
fi

if [ ! -f ${PRELOAD_FLAG} ]
then
    files=$(ls ${PRELOAD_SOURCE}/)
    for i in ${files};do
        cat  ${PRELOAD_SOURCE}/${i} > ${PRELOAD_DEST}/${i}
    done
    echo "abcd" > ${PRELOAD_FLAG}
fi

在主工程主mk中添加

 PRODUCT_PACKAGES += \

preloadvideo.sh

3   在和工程mk相同的文件夹下的init.board.rc

service preloadvideo /system/bin/logwrapper /system/xbin/preloadvideo.sh
        class main
        disabled
        oneshot

 preloadvideo.sh

4   frameworks/base/services/java/com/android/server/MountService.java

在方法notifyVolumeStateChange

else if (newState == VolumeState.Mounted) {
            if (DEBUG_EVENTS) Slog.i(TAG, "updating volume state mounted");
            updatePublicVolumeState(volume, Environment.MEDIA_MOUNTED);
            action = Intent.ACTION_MEDIA_MOUNTED;
            android.os.SystemProperties.set("ctl.start", "preloadvideo");

这个是加载内置存储的时候运行service   preloadvideo把视频复制到内置存储中
