How to use the Android NDK and NEON SIMD made easier
Google’s Android™ Native Development Kit (NDK)
is a tool that lets you build C/C++ and assembly libraries for your Android
applications. You might use this to improve performance for process intensive
portions of game, video or augmented reality apps or simply improve battery
performance on a mobile device. The NDK is not as polished as the Android SDK.
In this presentation, we’ll cover how to get started with the NDK from
installation, building, Java Native Interface (JNI) binding and other tips and
tricks for utilization, debugging and locating performance critical sections of
your native code. Finally, we’ll introduce you to Ne10, an open source,
optimized library for developers who don’t have the time to learn NEON™, the
ARM® SIMD architecture, or need best-practice examples of NEON intrinsics or
would like to contribute to an open source project targeting Android.
Who should attend:
Anyone who wants to develop for
Android and perhaps is new to ARM or wants to learn about the latest tips,
tricks and tools for improving your app’s performance.
Walk away points:
- Learn the basics of setting up and using the Android NDK to accelerate your
applications, program completely in C/C++ or re-use existing C/C++ code.
- Learn about a new, free tool for developing, debugging and analyzing Native
- Discover a new, open source project that demonstrates best-practice
implementations of NEON SIMD functions

Matt is a computer engineer
who’s been working with embedded software and system integration for over a
decade. He started using Linux in college, in the late 90’s, and has more than a
few lines of code in the USB stacks and drivers, as well as many consumer
devices from iPods to TVs to navigation systems. After a sabbatical in 2009 to
climb Mt. Everest, he returned to engineering contracting till summer of 2011. He
had a keen interest in Android and Google’s ‘release first and iterate fast’
designs and was hired by ARM as a developer evangelist to both improve our
tools, libraries and compiler technologies as they relate to Android internally
and to solicit developer input from independent applications developers, as well
as major device manufactures. Matt is very interested in hearing what developers
consider a priority to get the best performance and user experience from
ARM-powered® devices and happy to share some of the tools and projects ARM has
been working on.
