Book description
Create Android apps using Native C/C++ with the expert guidance contained in this cookbook. From basic routines to advanced multimedia development, it helps you harness the full power of Android NDK.
- Build, debug, and profile Android NDK apps
- Implement part of Android apps in native C/C++ code
- Optimize code performance in assembly with Android NDK
In Detail
Building Android applications would usually mean that you spend all of your time working in Java. There are however times when this is not the most efficient or best method for the application being built. This is where Android NDK comes in. 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.
The "Android Native Development Kit Cookbook" will help you understand the development, building, and debugging of your native Android applications. We will discover and learn JNI programming and essential NDK APIs such as OpenGL ES, and the native application API. We will then explore the process of porting existing libraries and software to NDK. By the end of this book you will be able to build your own apps in NDK apps.
"Android Native Development Kit Cookbook" begins with basic recipes that will help you in the building and debugging of native apps, and JNI programming. The recipes cover various topics of application development with Android NDK such as OpenGL programming and Multimedia programming. 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. 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.
