Android adb：无法建立连接，因为目标计算机主动拒绝了它

Question

需要帮助。

PC Windows 10，三星S4不带SIM卡（通过PC连接到同一wifi，通过USB连接到PC）。

至今。我已经尝试取消选中/检查USB调试，拔出/插入USB，打开/关闭Wifi，只是无法获得连接...可能是什么问题？

C:\Users\junew>adb devices

List of devices attached
d71ba392        device

C:\Users\junew>adb connect 192.168.0.27

unable to connect to 192.168.0.27:5555: cannot connect to 192.168.0.27:5555: No connection could be made because the target machine actively refused it. (10061)(nothing pops up on my screen)

C:\Users\junew>adb kill-server

C:\Users\junew>adb usb

* daemon not running; starting now at tcp:5037
* daemon started successfully

C:\Users\junew>adb connect 192.168.0.27

unable to connect to 192.168.0.27:5555: cannot connect to 192.168.0.27:5555: No connection could be made because the target machine actively refused it. (10061)(Window pops up on Samsung screen, but still unable to connect)

Answer 1

1.用USB线连接PC和设备。2.输入以下命令：

  adb kill-server
  adb tcpip 5555
  adb connect YourDeviceIpAddress(e.g 192.168.0.27, you could ensure it via viewing device configuration)
