Answer 1

上述错误的原因是，找不到任何设备或AVD连接。错误消息中的以下行显示：

> info: [debug] Trying to find a connected android device
> info: [debug] Getting connected devices...
> info: [debug] executing cmd: C:\Users\bizBoxChat\AppData\Local\Android\sdk\platform-tools\adb.exe devices
> info: [debug] 0 device(s) connected
> info: [debug] Could not find devices, restarting adb server...

> info: [debug] Error: Could not find a connected Android device.

仅在AVD管理器中创建AVD是不够的。它必须启动并运行（启动并准备就绪）。为此，请在AVD管理器中选择任何AVD，然后单击“开始”按钮。让AVD启动。等待。（它类似于真正的设备开启。）或者，需要连接一些真实设备。在该设备中，“开发者选项”应为开启。 “USB调试”应该开启。

转到命令提示符并运行以下命令：

adb devices

预期输出：某些设备或AVD应显示为已连接。一旦您看到任何设备或AVD连接，然后重试，您的问题就会得到解决。

注意：在命令窗口中运行“adb devices”命令时，如果看到“abd.exe是无法识别的内部或外部命令或批处理文件...”之类的消息，则需要在路径中包含adb.exe。您可以在环境变量中添加其路径，或者在运行“adb devices”之前运行以下命令：

set path=%PATH%;"D:\AndroidSDK\platform-tools"

请注意，adb.exe文件位于我的PC上的platform-tools文件夹中，位于Android SDK文件夹中。您需要修改此路径，就像在PC上一样。

Answer 2

尝试使用真实设备，因为仿真器非常慢，启动时间也会花费更多时间。即使是真正的设备，我也面临着这样的问题，

期待原因：

Android模拟器启动问题
亚行问题
系统配置

如果出现adb问题，则需要在cmd中运行以下命令：

adb kill-server
adb start-server

然后你尝试使用Android模拟器，并确保你的系统有足够的内存这些模拟器，如VM，这将CPU和＆amp;记住你的系统责任金额。

Answer 3

对我来说有帮助的是用最新的版本替换旧版的chromedriver。

Chrome browser is not able to navigate to any site in appium
