Python script sunflower one-key batch copy files

problem

QA Xiao Zhangxin took a test task, one of which requires the use of Android devices with batches of videos or pictures, and also requires the use of different models and system adaptations. If you use traditional manual copy operations, the cost is very high. First To find the system album and then copy it

There are few photos or videos in the album, so you need to perform multiple select copy operations in the album multiple times
There are few photos or videos in the album. If importing from the outside, make sure that there are batch files outside and understand the path to be imported
If it involves adaptation, it needs to be operated once on each device

problem analysis

Is there a solution that can automatically copy files?

Associated with the adb shell cp command supports file copying, you can consider automating the packaging script. In addition, before copying, you need to check the adb connection status, and you need to refresh the gallery after copying, otherwise the system album cannot update the copied files in time

Program	Advantage	Disadvantage
Scheme one manual operation	Direct operation, no time-consuming scripting	Repeated operations are time-consuming
Scheme two automation script	Develop once and use many times	Need to download and be familiar with the script

Python script implementation

Step 1: Check the adb connection status

 def check_adb_status(self):
        print("第一步：检查adb连接状态")
        command = 'adb devices'
        adbfile = os.popen(command, "r")
        result = adbfile.read()
        adbfile.close()
        # 对result处理，获取连接状态
        formatresult = result.replace('\n', '').replace(' ', '')
        if "	device" not in formatresult:
            print("adb连接失败，请重新连接\n")
            sys.exit(1)
        else:
            print("adb连接成功\n")
            self.get_lock_screen()

Step two realizes the function of copying. Two parameters file_path and copy_count are passed in, representing the source file path to be copied and the number of times to be copied.

 def run_copy_file(cls, file_path, copy_count):
        ADB_PUSH = 'adb push %s /data/local/tmp/' % file_path
        os.system(ADB_PUSH)
        time.sleep(2)
        filename = os.path.basename(file_path)
        print('filename名称为' + filename)
        now = datetime.datetime.now()
        nowtime = now.strftime('%Y_%m_%d_%H_%M_%S')
        count = 1
        while count <= copy_count:
            ADB_SHELL_CP = 'adb shell cp /data/local/tmp/%s /sdcard/DCIM/Camera/%s_%s_%s'\
                           % (filename, count, nowtime, filename)
            print("第%s次复制" % count)
            print("ADB_SHELL_CP*******" + ADB_SHELL_CP)
            os.system(ADB_SHELL_CP)
            time.sleep(2)
            count = count + 1

        #更新广播，刷新系统相册
        print("复制完成，刷新相册")
        os.system(ADB_SHLEL_BROADCAST)

Note: In order to identify the copied file, the file name is composed of three parts, the number of copies_current time_the name of the copied file, such as 29_2020_04_19_19_11_50_jiantou.gif script execution process and results

Pass in the local file path to be copied and the expected number of times of copying. Take the copying of gif file and the number of times of copying as 30 times for example, as follows

if __name__ == "__main__":
    cpfile = CopyFile()
    cpfile.check_adb_status()
    copy_file_count = 30
    # file_path = r"D:\技术\读书笔记\gaoxiaoxuexi.jpg"
    copy_file_path = r"D:\技术\读书笔记\jiantou.gif"
    # file_path = r'D:\技术\读书笔记\WeChat_20200409154818.mp4'
    CopyFile.run_copy_file(copy_file_path, copy_file_count)

Script execution results, screenshots are as follows

adb连接成功

第二步：开始检查设备锁屏状态

Encountered pit

After the file is copied, the system photo album still does not display the copied photos or videos. At this time, you need to refresh the gallery and execute the following command

Solution one can execute the following command

adb shell am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE -d file:///sdcard/DCIM/Camera

Option two restarts the device, if option one does not take effect
