Overview
About a month ago I got the urge to do some reverse engineering of ADB so that I could write an Android app that would be able to talk to devices the same way that the adb command-line tool distributed with the Android SDK does (without requiring root!).
The app that came about from this work has been on the Play Store about a month: https://play.google.com/store/apps/d...remotedebugger
I had planned to do an open-source release of the library that I wrote for the app, but hadn't found the time to tidy up the code until recently. So today is my official announcement of the open-source release of my ADB work.
TL;DR full sources and detailed JavaDoc are here: https://github.com/cgutman/AdbLib
Functionality
AdbLib implements a connection object (AdbConnection) that sits atop a standard Java Socket class which it uses as the underlying transport for the ADB connection and all streams operating over it. The AdbConnection object contains methods for the creation of AdbStreams which represent the underlying data streams of ADB. AdbConnection also maintains the connection thread responsible for processing and responding to packets from the target device.
The AdbConnection object has an associated AdbCrypto object which abstracts the 2048-bit RSA key authentication used on Android 4.2.2 and later. AdbCrypto also has the capability of saving and loading key pairs, along with generating a fresh key pair. AdbCrypto requires an implementation the AdbBase64 interface which does the conversion of the RSA public key to a Base-64 encoded string that is transmitted to the 4.2.2+ device the first time it connects.
There's also low level AdbProtocol class which has many useful definitions and functions for receiving, validating, and generating ADB packets. This class's methods and fields are used by AdbConnection for packet processing and generation.
Conclusion
Hopefully you guys can do something cool with this library. It's under the BSD license so there shouldn't be any problem getting it included in any projects. I'd be happy to help with any bugs found or provide assistance integrating the library into projects. I also accept patches/pull requests ;)
I've also published the Wireshark dissector I wrote to analyze the ADB protocol: https://github.com/cgutman/wireshark-adb-dissector
