Andrdoid built-in video file

Andrdoid built-in video file

This method is only suitable for scenarios with built-in storage.

1. Create a folder built_in_video under the vendor/sprd and place the built-in video file and copy steps.

Steps: 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

 

Include this internal_media.mk to the master mk.

Include vendor/sprd/built_in_video/internal_media.mk

 

2. Place the built-in USB flash drive in the preloadvideo folder created by vendor/sprd/open-source/tools, and copy the system/preloadvideo/Girs file to the built-in USB flash drive.

Android. mk is as follows:

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

Add
