Recently, I’m interesting how android adb works. If you are an Android
programer, you certainly familiar with adb shell,adb
logcat. Or maybe you only use eclipse, it is helpful to know behind DDMS
there is adb.
We can find adb description from android developer website.
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:
As introducted by google, it has three key 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.
