android-USB Host and Accessory（附加）

...可以通过USB连接，也可以使用无线连接设备进行调试

Android supports a variety of USB peripherals(周边设备) and Android USB accessories (hardware that implements the Android accessory protocol) through two modes: USB accessory and USB
host.

》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

.
