Also, most of the time when you will use NDK as it was intended – for moving the most performance-critical parts of code to the native layer – you are not likely to need much OOP abstraction and other design goodies. For example, exceptions are not supported and there are some known bugs in static constructor/destructor invocations. While NDK supports both C and C++, C++ support is rather limited. (we’re not going to use our old project, foobar, so you can just close it.) In short, we have a basic Eclipse installation, plus Android SDK and ADT that brings Android support to Eclipse: This is where we stand right after we’re done with the previous tutorial. Ready? Let’s go! Step 1: Installing C/C++ Support on Eclipse The downloads that are necessary for the initial configuration of the environment might take some time (around 30 minutes total), so be prepared. We will also create a basic skeleton project that uses NDK that you can use as the foundation for your NDK-powered apps. In this tutorial we will take our basic Android development environment that we created in one of the previous articles and add NDK support to it. libc – it’s there for compatibility and perhaps to allow you to port existing native code.2D graphics – pixelbuffer support (only starting with 2.2).Math (some, but not all, calculation-intensive algorithms might benefit from being done on the native layer).OpenGL, including support for some newer versions that the (Java) SDK supports.And, while there are cases where NDK will be really helpful for your app, NDK has a rather limited API that’s mostly focused on several performance-critical areas, such as: Although it does have a maintenance cost and does add technical complexity to your project, NDK is not difficult to install or use in your project. Well, both opinions are rather wrong, as I hope to show further in this post. Many developers who are not familiar with NDK think it is 1) complex to understand and use, and at the same time a lot of developers will think it is a sort of a 2) silver bullet that can solve any problem that can’t be solved with SDK. Since NDK is distributed separately from the SDK, including documentations and samples, you are not likely to get familiar with NDK before you actually try it as a solution to one of your development challenges.īecause of that, many people think of NDK as of “black magic” of Android development. While everyone is aware that there is the NDK (the Native Development Kit), they don’t face the need to use it. Most Android developers start their learning from pure Java, Android SDK based apps.
