This document provides an introduction to the Android x86 platform. It discusses how Android development tools like the Android SDK and Intel HAXM can be used to quickly emulate Android on Intel architecture PCs. Most existing Android apps written in Dalvik or using the NDK should be easily portable to x86. The document outlines opportunities for developers to optimize apps for Intel Atom phones and market them through channels like the Android Market. It invites developers to take advantage of Intel's tools and resources to build apps for the next generation of Intel-based computing experiences.

9. Faster Emulation for any Android developer using
an IA-based host PC
Pre-built Atom Images
• Android SDK manager has x86 emulation
images built-in
• To emulate an Atom-based Android phone,
install the “Intel Atom x86 System Image”
available in the Android SDK Manager
Much Faster Emulation
• Intel® Hardware Accelerated Execution Manager
(HAXM) for Mac and Windows uses Intel®
Virtualization Technology (VT) to accelerate
Android emulator by 2-4x
• Intel VT is already supported in Linux* (KVM)
for x86.
See www.intel.com/software/android for demo
videos & installation tips

10. Applications Enabling on Atom - Dalvik
• The majority of Android apps are Dalvik apps
Android Runtime
– Intel’s extensive experience in optimizing Java VMs has been Dalvik Virtual
applied to Dalvik VM. Machine
• IA-optimized x86 fast interpreter is part of AOSP Core Libraries
mainline and actively maintained
• IA-optimized Trace JIT compiler yields significant performance gains
• Intel continues to invest heavily in Dalvik VM optimizations
• x86 Native Code Generation (NCG) for aggressive compiler optimizations
• Increased performance for CPU- and graphic-intensives apps
• Continued optimizations for memory management
Apps written in Dalvik Java should run “as is”

• Straightforward recompile (with NDK) and
repackage (with SDK) for most existing NDK Android

– Unless the native code uses ARM-specific features,
porting the app = simple recompile Android App with

– If the app uses ARM-specific features Dalvik
JNI/Native
• Must add equivalent x86-specific function calls but can optimized Java
code libraries
still maintain a single code base and apk for x86 and ARM Classes
