Open command prompt as administrator and enter below commands:以管理员身份打开命令提示符并输入以下命令：
- "adb kill-server" “亚行杀服务器”

Install drivers for you phone if you're not testing on emulator.如果您不在模拟器上进行测试，请为您的手机安装驱动程序。
Open android sdk manager and check/install "Google USB Driver" from extras folder.打开 android sdk 管理器并从 extras 文件夹中检查/安装“Google USB 驱动程序”。

I was using Windows 7 and my adb driver was not working tried everything even google driver was showing error when i updated driver that it is not compatible with 32 bit.我使用的是 Windows 7，我的 adb 驱动程序无法正常工作，尝试了所有操作，甚至当我更新驱动程序与 32 位不兼容时，谷歌驱动程序也显示错误。 I tried changing cables and commands but it was showing exclamation mark on ADB interfaces in other devices inside device manager.我尝试更改电缆和命令，但它在设备管理器内的其他设备的 ADB 接口上显示感叹号。 Adb devices was also not showing any devices. Adb devices 也没有显示任何设备。 I installed universal adb driver and now it is working fine.我安装了通用 adb 驱动程序，现在工作正常。 Hope it helps.希望能帮助到你。

Probably won't work and you already have tried it, but if no one of the previous answers help, sometimes it's usb cable's fault.可能行不通，您已经尝试过了，但是如果之前的任何一个答案都没有帮助，有时是 USB 电缆的问题。 Just try an other one to be sure.只需尝试另一个以确保。
