Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device. It is a client-server program that includes three components:
- A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients.
- A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device.
- A daemon, which runs as a background process on each emulator or device instance.
You can find the adb tool in <sdk>/platform-tools/. Where to download Android SDK
On XO-4 since we only has USB host port, the way of using ADB is a little different from a typical Android device. We use ADB via WIFI instead of via USB.
First, make sure the deamon on your XO-4 is enabled.
Settings->Developer options(How to enable developer options)->USB debugging
Then, enable WIFI on XO-4 and get the IP address.
Settings->Wi-Fi->Menu on top right corner(three points)->Advanced->IP address
Connect XO-4 using ADB tools on your development machine.
