Getting Started with the NDK

The Native Development Kit (NDK) is a set of tools that allow you to leverage C and C++ code in your Android apps. You can use it either to build from your own source code, or to take advantage of
existing prebuilt libraries.
The NDK is not appropriate（恰当） for most novice（初学者） Android programmers, and has little value for many types of Android apps. It is often not worth the additional complexity（复杂） it inevitably（不可避免的） brings to the
development process. However, it can be useful in cases in which you need to:
Squeeze（压榨 挤压
挤进） extra performance out of a device for computationally（计算） intensive（密集） applications like games or physics（物理） simulations（模拟）.
Reuse重用 your own or other developers' C or C++ libraries.
This guide gives you the information you need to get up and running with the NDK. It starts by explaining the concepts underpinning基础
the NDK, and how to set it up. Next, it continues with information about targeting different
hardware platforms in your builds. Then, it explains how to use the NDK to build and debug your
app. Finally, it discusses how to use your own and other prebuilt libraries.
