Operation timed out
Connection refused

记录通过网络连接adb遇到的问题。

Operation timed out

$ adb connect 192.168.31.157:5555
failed to connect to '192.168.31.157:5555': Operation timed out

遇到这种报错，多半是网络问题，需要检查android设备和主机之间的网络连接情况，用ping命令验证连接。

Connection refused

$ adb connect 192.168.31.157:5555
failed to connect to '192.168.31.157:5555': Connection refused

基本上是adb服务出了问题，
开启adb两种方式

shell：start adbd
图形界面，“设置->系统->开发者选项->USB 调试”，没有的话可以百度下如何打开开发者选项。

其中第一种方式，在开启adb之前，需要检查一下, service.adb.tcp.port，如果是空需要设置一下端口号，与adb connect命令中的端口号对应

$getprop service.adb.tcp.port$setprop service.adb.tcp.port 5555
$getprop service.adb.tcp.port
5555stop adbd
start adbd
