无法连接到tcp:5037:无法连接到127.0.0.1:5037:无法建立连接,因为目标计算机主动拒绝它.(10061)

嗨,我是新手,android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 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..？

请确保您已安装设备驱动程序和adb服务,并激活USB调试中android device -> setting -> developer options ,并且必须能够看到您的设备,当你通过USB端口连接(通过这个命令:adb devices),

所以当你通过USB连接遵循这一命令:

1,保持连接通过USB
2连接到您的WIFI网络(计算机和移动设备)
3- ping DeviceIP(必须ping到您的设备)
4- adb kill-server
5- adb usb
6- adb tcpip 5556
7- adb connect "yourDeviceIP:5556"
8- adb devices(必须看到两个设备名称,其中一个是通过deviceIP:5556)
9 - 拔下USB线,

然后完成!你可以测试你的应用程序
