Android is now open source software and available for download from official website. It is a software platform and operating system for mobile devices. It is based upon Linux kernel and developed by Google and Open Handset Alliance. Today, Google made exciting announcement – they have now released the source code for Android. There’s a huge amount of code and content there, so head over to official website to grab all the details.
From the project site:
Android is the first free, open source, and fully customizable mobile platform. Android offers a full stack: an operating system, middleware, and key mobile applications. It also contains a rich set of APIs that allows third-party developers to develop great applications.

This article explains some of the more important syntactic and semantic differences between two of the most popular assemblers for LinuxÂ®, GNU Assembler (GAS) and Netwide Assembler (NASM), including differences in basic syntax, variables and memory access, macro handling, functions and external routines, stack handling, and techniques for easily repeating blocks of code.
Unlike other languages, assembly programming involves understanding the processor architecture of the machine that is being programmed. Assembly programs are not at all portable and are often cumbersome to maintain and understand, and can often contain a large number of lines of code. But with these limitations comes the advantage of speed and size of the runtime binary that executes on that machine. Even though the differences between these two assemblers are substantial, it’s not that difficult to convert from one form to another. You might find that the AT&T syntax seems at first difficult to understand, but once mastered, it’s as simple as the Intel syntax.
