为保证自动化架构下代码生产和维护的低成本，本着最大化封装的目标构造代码。
以下是对外接手机识别和启动的基本操作方法。

import uiautomator2
import os

    adbLocation = toolkit.File.getAdbPath()
    commandStrClean = adbLocation + ' -s ' + deviceId + ' shell ' + 'pm clear ' + appName
    commandStrStat = adbLocation + ' -s ' + deviceId + ' shell ' + 'am start -n ' + appName + '/' + appActivity
    os.system(commandStrClean)
    time.sleep(toolkit.Time.envDly() * 1)
    os.system(commandStrStat)

    return device

    # print(str_init)
