无数据线 debug

当你没有数据线的时候也想debug,怎么办？还有就是测试串口的时候，那个插口要被占用，无法跟电脑保持adb连接，怎么办？

话不多说。官方文档

Debugging considerations

When debugging applications that use USB accessory or host features, you most likely will have USB hardware connected to your Android-powered device. This will prevent you from having an 

adb

 connection to the Android-powered device via
USB. You can still access 

adb

 over a network connection. To enable 

adb

 over a network connection:
Connect the Android-powered device via USB to your computer.
From your SDK 

platform-tools/

 directory, enter 

adb tcpip 5555

 at the command prompt.
Enter 

adb connect <device-ip-address>:5555

 You should now be connected to the Android-powered device and can issue the usual 

adb

 commands like 

adb logcat

.
To set your device to listen on USB, enter 

adb usb

.

具体如下
1：借根数据线连上手机和电脑

2：打开终端cmd，cd到sdk里的platform-tools/目录，输入adb tcpip 5555

3：查看手机ip，然后输入adb connect 手机ip : 5555

4：完成，还线
