Answer 1

造成上述错误的原因是，任何设备或AVD都找不到连接。错误消息中的下列行显示如下：

> 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.

仅仅在AVD管理器中创建AVD是不够的。它必须启动和运行(启动和准备)。要做到这一点，请在AVD经理中选择任何AVD，然后单击“开始”按钮。让AVD启动。等。(它类似于真正的设备打开。)或者，一些真正的设备需要连接。在该设备中，“开发人员选项”应该是打开的。"USB调试“应该打开。

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应显示为连接。一旦您看到任何设备或AVD连接，并重新尝试，那么您的问题将得到解决。

注意:在命令窗口中运行"adb设备“命令时，如果您看到类似于"abd.exe是一个无法识别的内部或外部命令或批处理文件.”之类的消息，则需要在路径中有adb.exe。您可以在环境变量中添加它的路径，或者在运行"adb设备“之前只运行以下命令：

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

请注意，adb.exe文件在我的PC上的平台工具文件夹中，在Android文件夹中。您将需要修改此路径，因为它在您的PC上。

Answer 2

尝试使用真正的设备，因为仿真器非常慢，启动时间也需要更多的时间。即使是真正的设备我也面临着这样的问题，

预期原因：

1. Android模拟器启动问题
2. 亚行发行
3. 系统配置

如果亚行出现问题，则需要在cmd中运行以下命令：

adb kill-server
adb start-server

然后尝试使用Android仿真器，并确保系统有足够的内存，这些仿真器就像VM一样，这将是CPU &系统内存的责任量。
