Abstract

Google's Android Native Development Kit (NDK) is a toolset that lets you embed components to use of native code in your Android applications. It makes possible for developers to easily compile in C/C++ for the Android development platform. Generally, developer does not concern how effective between native code and Dalvik Java code that will causes poor performance of Android. There are some researches discussed about benchmark Java and C/C++. But they do not consider the issues of Dalvik and native code for Android programming or evaluate them in real Android device. In this work, we use a more complete approach to benchmark Dalvik java code and Native code on real Android device. We conducted 12 test programs to analyze the performance and found that native code faster than Dalvik Java code for about 34.2%.

Android系统的基准Dalvik和本地代码

b谷歌的Android Native Development Kit (NDK)是一个工具集，可以让你在Android应用程序中嵌入组件以使用本地代码。它使开发人员可以轻松地在Android开发平台上用C/ c++进行编译。一般来说，开发者并不关心原生代码和Dalvik Java代码之间的效率如何，这会导致Android的性能不佳。对Java和C/ c++的基准测试进行了一些研究。但他们没有考虑Dalvik和Android编程的本地代码问题，也没有在真实的Android设备中进行评估。在这项工作中，我们使用更完整的方法在真实的Android设备上对Dalvik java代码和Native代码进行基准测试。我们进行了12个测试程序来分析性能，发现本机代码比Dalvik Java代码快34.2%左右。
