This whitepaper discusses the Android* NDK, a tool set for developing Android* applications with embedded native code. It describes the basic coding structures of NDK applications. It also provides instructions on how to install the NDK, and how to use the NDK to build applications.
The NDK helps the Android* developer include C or C++ code in their applications. It consists of the following components:
The main goals of the NDK include:
Coding in C or C++ does not always result in higher performance of the applications. Instead it always increases the complexity of the code. Outside of the two main goals discussed above, we encourage developers to implement new functionalities solely based on the Android* SDK.
The Android* SDK
You can go to http://developer.android.com/sdk/ndk/index.html to find the NDK installation package.
The Android* NDK is based on the Java* Native Interface (JNI) programming framework.
You can build your native code by running "$NDK/ndk-build" script from your project directory, or any of its sub-directories.
The NDK provides a command line script ndk-gdb which can be used to debug the embedded native code.
For Intel® architecture-based Android* platforms, the NDK is a very useful complement to the SDK. It enables the reusability and under some circumstance increases the performance. With these fundamental goals, the NDK provides a set of tools to build, integrate, test, and debug the native source code embedded in the application. On the other hand, the NDK increases the coding complexity. It should be applied only to achieve the goals described here.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
