Reading the Android Source code

Question

I am currently compiling ROM from the android source and it works fine But now I have decided to read about all the packages that are used I.e. Git , make , gnu , repo , curl, libdev ..

But I also want to read the android core source code . Can anyone point out from where should I start ? Also what languages do I need to know? Currently I am familiar with C , C++ , Java Also I have made android apps of my own , so I am familiar with android environment And also mark up languages like XML HTML JavaScript

I suppose if I need to read kernel source code I need to learn assembly language? Though I would keep the kernel aside for now .

Answer 1

Its best to buy yourself a dev-kit like RIoT board or Wandboard, and install Android on it. You can then compile Android yourself, step through it etc. That will give you ideas on what part of the platform you should read. HTH

Answer 2

The main code of Android are written by java and c&c++. The SDK are java code and bind to native code via JNI.

So, the SDK code should be a good start since you already familiar with those API. Then, you can dig into it and reach the native layer.
