C:UsersAdministrator>adb devices List of devices attached adb server version (31) doesn't match this client (40); killing... could not read ok from ADB Server * failed to start daemon error: cannot connect to daemon
一、版本报错
在命令行中使用adb nodaemon server -a
C:UsersAdministrator>adb nodaemon server -a adb I 08-01 09:43:24 13836 15900 auth.cpp:421] adb_auth_init... adb I 08-01 09:43:24 13836 15900 auth.cpp:174] read_key_file 'C:UsersAdministrator.androidadbkey'... adb I 08-01 09:43:25 13836 12588 transport.cpp:103] 201c1005: read thread spawning adb I 08-01 09:43:25 13836 3400 transport.cpp:116] 201c1005: write thread spawning adb I 08-01 09:43:25 13836 15900 auth.cpp:472] Calling send_auth_response adb I 08-01 09:43:25 13836 15900 adb.cpp:145] 201c1005: offline
完美解决
C:UsersAdministrator>adb devices
List of devices attached
201c1005 device
二、sdk版本与第三方模拟器adb版本不对
