This helps the Dalvik VM to locate the native function at runtime. The package and class name must agree with the package and class name of the Java class from which the native method is called, while the method name must be the same as the method name declared in that Java class. The native function name must follow a specific pattern for a package name, class name, and method name.

The native function naGetHelloNDKStr returns the Hello NDK string to the caller, as indicated in both the native code function definition and Java code method declaration. Native code: The Hello NDK program consists of both the native C code and Java code. At the end of the chapter, we will write a Hello NDK program with the environment setup.

For developers who have set up an Android NDK development environment before, a recipe with detailed steps of how to update an NDK development environment is provided.

This chapter will cover how to set up Android NDK development in Windows, Ubuntu Linux, and Mac OS. With the understanding of the pros and cons of NDK, we can start our journey to Android NDK. NDK cannot access lots of APIs available in the Android SDK directly, and developing in NDK will always introduce extra complexity into your application. It is not recommended to work in NDK simply because one prefers programming in C or C++ over Java. This does not only speed up the development significantly, but also allows us to share code between Android and non-Android projects.īefore we decide to use NDK for an Android app, it is good to know that NDK will not benefit most Android apps. The second advantage of NDK is that it allows the porting of existing C and C++ code to Android. Therefore, we only stated that it may improve the app's performance. In fact, developing in NDK doesn't guarantee a performance improvement and can actually harm performance at times. Calling JNI methods introduces extra work for the Dalvik VM and since the code is compiled, no runtime optimization can be applied. The advantages of using native code do not come free. But in many cases, native code still runs faster than Java code. At Android 2.2 or higher, a Just-In-Time ( JIT) compiler is added to Dalvik VM to analyze and optimize the Java byte-code while the program is running (for example, JIT can compile a part of the byte-code to binary code before its execution). Firstly, the native code is compiled to a binary code and run directly on OS, while Java code is translated into Java byte-code and interpreted by Dalvik Virtual Machine ( VM). The performance improvements can come from three sources. Many multimedia applications and video games use native code for processor-intensive tasks. This is usually true for many processor-bound applications. Before we start our journey to NDK, it is important to understand the advantages of NDK.įirst of all, NDK may improve application performance. If you are looking for ways to make your application available in Android and take measures to boost your application’s performance, then this Cookbook is for you.Īndroid NDK is a toolset that allows developers to implement a part of or an entire Android application in a native language, such as C, C++, and assembly. We will begin with a simple recipe, Hello NDK, before moving on to cover advanced topics with recipes on OpenGL ES that focus on 2D and 3D graphics, as well as recipes that discuss working with NDK and external APIs.

The recipes cover various topics of application development with Android NDK such as OpenGL programming and Multimedia programming. "Android Native Development Kit Cookbook" begins with basic recipes that will help you in the building and debugging of native apps, and JNI programming. By the end of this book you will be able to build your own apps in NDK apps.

We will then explore the process of porting existing libraries and software to NDK. We will discover and learn JNI programming and essential NDK APIs such as OpenGL ES, and the native application API. The "Android Native Development Kit Cookbook" will help you understand the development, building, and debugging of your native Android applications. Android NDK allows the developer to write in Native C/C++, giving you the power to reuse code and libraries and also, in most cases, increase the speed and efficiency of your application. There are however times when this is not the most efficient or best method for the application being built. Building Android applications would usually mean that you spend all of your time working in Java.
