We have seen significant code size improvements over GCC and open source LLVM with the bare metal version of the Snapdragon LLVM toolchain. To use the Snapdragon LLVM Compiler for Android, you must have the recent version of the Android SDK and Android NDK installed on your build machine.ĭownload the Snapdragon LLVM Compiler for bare metal images.īare metal images typically do not run on top of an operating system, instead they directly interact with the hardware. We also observe performance improvements in the libpng library when using the Snapdragon LLVM compiler compared to the LLVM or GCC compilers included in the Android NDK. For example, in our tests the C version of the Android jpeg library performs 10% faster on Snapdragon-based devices when built with the Snapdragon LLVM compiler compared to the latest NDK GCC version. We have seen performance gains to a variety of Android applications and libraries when compiling with LLVM. has been working on optimizing this mobile-friendly compiler for Snapdragon and we are pleased to make it available to you.ĭownload the Snapdragon LLVM Compiler for Android NDK. LLVM is suitable wherever you use native code (C/C++) in your Android application.Īs a key supporter of LLVM, Qualcomm Technologies, Inc. Beginning with the Jellybean MR1 release, Google has included LLVM as an alternative compiler as part of the Android toolchain and the Android NDK. It enables use of compilers in a broader range of configurations, providing for better performance and power usage – particularly on Snapdragon micro-architectures. LLVM is a C/C++ compiler that is becoming increasingly popular. O’Reilly members experience books, live events, courses curated by job role, and more from O’Reilly and nearly 200 top publishers.Snapdragon LLVM Compiler Toolchain is now available for the following: ![]() Get Expert Android Studio now with the O’Reilly learning platform. NDK might look scary if you are not familiar with C/C++ however, it can unleash the full potential of your device's hardware and native libraries, and is well worth the effort. If you are an Android NDK newbie looking to learn NDK, we suggest you visit and follow the tutorials and code samples. We strongly suggest keeping your tools up-to-date and that you follow the updates to NDK integration if your application relies on NDK. This chapter does not aim to teach Android NDK from the ground up but focuses instead on how to use Android NDK with the new Android Studio and Gradle.Īt the time of this writing, Android NDK integration with Android Studio is still experimental and subject to change. Although Android NDK is a powerful tool, many Android developers and projects may not need to use it. Native code is commonly used in Android projects for games and applications, which require high performance face recognition, audio processing, and so on. ![]() This chapter focuses on the details of Android NDK and shows you how to build native C/C++ code in Android Studio. ![]() Building NDK projects for multiple platforms.Building NDK applications with Android Studio and Gradle.Starting a new NDK application in Android Studio.Chapter 11 Using Android NDK with Android Studio ![]()
