android - 无法连接到 tcp :5037: cannot connect to 127. 0.0.1 :5037: No connection could be made because the target machine actively refused it. (10061)

Question

嗨，我是 android 的新手，我无法运行 adb.exe，它给我以下错误:

==>adb start-server
adb I  6108  5748 adb.cpp:219] Android Debug Bridge version 1.0.32
adb I  6108  5748 adb.cpp:219] Revision 09a0d98bebce-android
adb I  6108  5748 adb.cpp:219]
adb I  6108  5748 adb_client.cpp:126] _adb_connect: host:version
adb I  6108  5748 sysdeps_win32.cpp:742] could not connect to tcp:5037: cannot connect to 127.0.0.1:5037: No connection could be made because the target machine actively refused it. (10061)
adb I  6108  5748 adb_client.cpp:175] adb_connect: service host:start-server
* daemon not running. starting it now on port 5037 *
Cannot open 'nul': The system cannot find the file specified. (2)
* failed to start daemon *
error: cannot connect to daemon

这个错误究竟意味着什么......？

Cannot open 'nul': The system cannot find the file specified. (2)  

这是什么错误……？

确保您已安装设备驱动程序和 adb 服务并在 android device -> setting -> developer options 中激活 USB 调试 并且当您通过 USB 端口连接时必须能够看到您的设备(通过此命令:adb devices)

因此，当您通过 USB 连接时，请遵循以下命令:

1-stay 通过 USB 连接
2-连接到您的WIFI网络(电脑和移动设备都可以)
3-ping DeviceIP(必须能ping到你的设备)
4- adb kill-server
5-adb usb
6-adb tcpip 5556
7-adb connect "yourDeviceIP:5556"
8-adb devices (一定要看到两个设备名，其中一个是deviceIP:5556)
9-拔下USB线

然后就完成了!你可以测试你的应用程序
