python 对外接手机基本操作方法

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
import time
import re
import toolkit.File

def startApp(deviceId, appName, appActivity):
    #返回启动APP后的设备对象
    # deviceId/设备ID: str '69DDU16528010559'
    # appName/app名: str 'cn.appname.android.driverclient.debug'
    # appActivity/app加载项: str 'cn.appname.android.driverclient.LauncherActivity'
    device = uiautomator2.connect_usb(deviceId)
    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


def getDevicesId():
    #返回当前连接设备DEVICEIS列表
    adbLocation = toolkit.File.getAdbPath()
    str_init = ' '
    all_info = os.popen(adbLocation + ' devices').readlines()
    # print('adb devices 输出的内容是：', all_info)
    # print(len(all_info))
    for i in range(len(all_info)):
        str_init += all_info[i]
    # print(str_init)
    devicesId = re.findall('\n(.+?)\t', str_init, re.S)

    # print('所有设备名称：', devices_name)
    return devicesId

def getDeviceId():
    #返回当前连接设备DEVICEIS列表中第一个值
    adbLocation = toolkit.File.getAdbPath()
    str_init = ' '
    all_info = os.popen(adbLocation + ' devices').readlines()

    for i in range(len(all_info)):
        str_init += all_info[i]

    deviceId = re.findall('\n(.+?)\t', str_init, re.S)

    return deviceId[0]
