推荐答案
出现上述错误的原因是，找不到任何设备或AVD.错误消息中的以下几行显示了这一点:
Reason of above error is, any device or AVD could not be found to be connected. Following lines in your error message show this:
> 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(已启动并准备就绪).为此，请在您的AVD管理器中选择任何AVD，然后单击开始"按钮.让AVD启动.等待. (这类似于打开真实设备.) 或者，需要连接一些真实的设备.在该设备中，开发人员选项"应为开. "USB调试"应该打开.
Just creating AVD in AVD manager is not sufficient. It has to be up and running (started and ready). To do that, select any AVD in your AVD manager, and click on "Start" button. Let the AVD boot. Wait. (It is similar to a real device switching on.) Or, some real device needs to be connected. In that device, "Developer Options" should be On. "USB debugging" should be On.
转到命令提示符并运行以下命令:
Go to command prompt and run following command:
adb devices
预期的输出:某些设备或AVD应该显示为已连接. 一旦看到任何设备或AVD已连接，然后重试，即可解决您的问题.
Expected output: Some device or AVD should be shown as connected. Once you see any device or AVD connected, and retry, then your problem will be solved.
注意: 在命令窗口中运行"adb设备"命令时，如果看到诸如"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，也可以在运行"adb设备"之前直接运行以下命令:
Note: On running "adb devices" command in command window, if you see message like "abd.exe is an unrecognized internal or external command or batch file...", then you need to have adb.exe in path. You can add its path in environment variables, or simply run following command before running "adb devices":
set path=%PATH%;"D:\AndroidSDK\platform-tools"
请注意，adb.exe文件位于我PC上的platform-tools文件夹中，位于Android SDK文件夹中.您将需要修改此路径，就像在PC上一样.
Note that adb.exe file is in platform-tools folder on my PC, in Android SDK folder. You will need to modify this path as it is on your PC.
