    【已解决】自动测试工具优化adb的无线WiFi连接网络切换支持之后的效果
    期间，又先后遇到几次错误。
    期间由于网络中断导致了报错：

RuntimeError: USB device 192.168.31.84:5555 is offline
    只能重新测试了。
    也是网络问题，不是代码问题。
    刚才又出现一次同样问题：
            self.__client._prepare_atx_agent()
      File "/Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/venv/lib/python3.8/site-packages/uiautomator2/__init__.py", line 286, in _prepare_atx_agent

    RuntimeError: USB device 192.168.31.84:5555 is offline
    貌似网络虽然慢，但是是正常的？
    不确定是否是网络问题导致的。
    重试。
    问题依旧：
    用adb去安装apk：

    但是过了会报错：

    RuntimeError: USB device 192.168.31.84:5555 is offline
    这次，貌似不是网络问题。
    不过也看出点其他问题：
    对于uiautomator2，显示出：
    USB disconnected, fallback to WiFi, ATX_AGENT_URL=http://192.168.31.84:7912
    那感觉是：
    uiautomator2，把最开始的连接，当成USB有线连接了？
    虽然表面上是用：
    u2.connect(“192.168.31.84:5555")
    去用无线WiFi连接的。
    但是估计是内部判断成有线USB了。
    所以后续才会这种报错的。
    所以感觉有必要去，改为：
    middleware/config.yml
    # adb and uiautomator2 connect android phone use:
# isWirelessConnect: False # Wired USB cable
isWirelessConnect: True # Wireless WiFi
    src/common/DevicesMethods.py
        def init_device_driver_Android(self):
        # 连接uiautomator2服务
        logging.info("start init driver")
        if self.config["isWirelessConnect"]:
            # self.driver = u2.connect_wifi(self.device)


            self.driver = u2.connect_adb_wifi(self.device)
            # Equals to
            # + Shell: adb connect 10.0.0.1:5555
            # + Python: u2.connect_usb("10.0.0.1:5555")
        else:
            self.driver = u2.connect(self.device)
    去调试看看，看看后续，当网络断开后，是否还会提示：USB disconnected
    输出：
    [201217 16:36:53][DevicesMethods.py 88 ] start init driver

    其中的：
    already connected to 192.168.31.84:5555
    说明内部的确调用了：
    Shell: adb connect 10.0.0.1:5555
    继续。

    然后目前重试，是没问题的：

    就看之后效果了：
    是否还会出现，我觉得不应出现的：
    USB disconnected
    方面的提示。
    结果很快，（可能是网络不稳定导致的？）

    又有错误了。
    虽然没看到：USB disconnected
    但是：USB device 192.168.31.84:5555 is offline
    说明也是把设备当成USB有线连接了？
    又或者是，只是提示不够友好，应该写成WiFi无线设备
    但是内部代码逻辑其实都正常，都没问题？
    继续多次测试看看。
    暂时忽略上述警告，代码可以继续运行。
    或许是已经解决了问题了。
    并没有。
    此处，后续uiautomator2没工作：
    对于自动监测到并输入vivo密码 没生效：
    所以，此处需要：
    重启调试，或者想办法代码中加上支持：
    能让uiautomator2重新连接才可以。
    那去加上试试：
    src/AppCrawler.py
        def gameAutomation_Manual(self):
。。。
            "5": "initDriver",
        }
。。。
                elif curOptionNum == "5":

    去调试看看效果：

    结果有问题。
    没法触发代码调试。
    算了。重新调试吧。
    遇到了，切换WiFi，去调试：

。。。
[201217 17:30:23][DevicesMethods.py 88 ] start init driver
already connected to 192.168.31.84:5555
    是可以成功初始化driver，打印出信息的：
    [201217 17:30:32][DevicesMethods.py 111] driverInfo={'currentPackageName': 'com.sj.sbcq.vivo', 'displayHeight': 1459, 'displayRotation': 0, 'displaySizeDpX': 360, 'displaySizeDpY': 800, 'displayWidth': 720, 'productName': 'PD2065', 'screenOn': True, 'sdkInt': 29, 'naturalOrientation': True}

    即：
    adb和uiautomator2的driver分别都可以初始化
    继续调试，看看是否正常。
    至少此处是没问题的。后续代码运行正常。
    那可以再去加一个：
    6: reConnectAdb_reInitU2Driver
    "6": "adbConnect+initDriver”,

                elif curOptionNum == "6":
                    logging.info("Reconnect adb and reinit driver:")
                    isConnected = self.connectDevice()
                    logging.info("%s to connect current %s device %s", isConnected, self.platformType, self.device)
                    logging.info("re-init %s driver", self.platformType)
                    self.init_device_driver()
    看看后续调试如何
    目前看来没问题。

    顺带也去看看
    uiautomator2 RuntimeError USB device is offline
    uiautomator2/__init__.py at master · openatx/uiautomator2
    android adb devices offline的解决办法 – 清风软件测试 – 博客园
    android – adb device offline with ADB wireless – Stack Overflow
    android – Error: device offline – Stack Overflow
    【总结】
    此处，对于网络切换的，导致WiFi连接的adb和uiautomator2断开了，报错：
    RuntimeError: USB device 192.168.31.84:5555 is offline
    解决办法：
    之前对于uiautomator2的初始化代码，变成显示指定wifi：
        def init_device_driver_Android(self):
        # 连接uiautomator2服务
        logging.info("start init driver")
        if self.config["isWirelessConnect"]:
            # self.driver = u2.connect_wifi(self.device)

            self.driver = u2.connect_adb_wifi(self.device)
            # Equals to 
            # + Shell: adb connect 10.0.0.1:5555
            # + Python: u2.connect_usb("10.0.0.1:5555")
        else:
            self.driver = u2.connect(self.device)

    以及：
    后续如果断开，再去：
    输入6，然后：
                    elif curOptionNum == "6":
                    logging.info("Reconnect adb and reinit driver:")
                    isConnected = self.connectDevice()
                    logging.info("%s to connect current %s device %s", isConnected, self.platformType, self.device)
                    logging.info("re-init %s driver", self.platformType)
                    self.init_device_driver()
    • 重新adb（通过WiFi）连接安卓设备
    • 重新初始化driver驱动 = uiautomator2的重新初始化
    如此，即可解决：
    当WiFi网络切换，导致adb和uiautomator2断开的问题。
    【后记20201218】
    当手机中uiautomator2没启动时，去调试：
    self.driver = u2.connect_adb_wifi(self.device)
    则会触发：
