andrdoid内置视频文件

这种方法仅仅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下新建一个目录built_in_video 里边放置要内置的视频文件及copy脚步

脚步例如以下: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新建目录preloadvideo里边放置载入内置U盘后把system/preloadvideo/Girs文件拷贝到内置U盘中

Android.mk例如以下

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project主mk中加入

PRODUCT_PACKAGES += \

preloadvideo.sh

3   在和projectmk同样的目录下的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");

这个是载入内置存储的时候执行service   preloadvideo把视频拷贝到内置存储中
