Press the “Apply” button and you are all set without the need to worry about the options and installations.įigure 2: NDK Tools by Android Studio Setting Up for a Hello-world Build In Figure 2, it is the SDK Manager started up by Android Studio when you go to its menu under “Tools -> Android.” Switch to “SDK Tools” and you should see the recommended tools highlighted in Figures 1 and 2. We are going to take advantage of this convenient offer and focus on how we establish the connection between Android and native code. Luckily, you can simply avoid adventuring through all the trouble of setting up the preferred tools by using the defaults provided to you in Android Studio. To open this dialog, you can right-click the project and select “Open Module Settings.” It is under the “SDK Location” tab on the left-hand side panel. When all these tools are installed, the most important thing you want to check is whether you have the NDK default directory pointing to the downloaded package, as in Figure 1. Then, you’ll need to download your preferred native compiler for example, the freely available CMake. The NDK download is also available, so you can download the package and do it manually after choosing the correct platform. Downloading and Installing NDK-related Toolsīecause Android is only fully supported in the Android Studio IDE, I would recommend you go ahead and get its latest version (3.0.1 as of now). Finally, we walk through a more complicated example to illustrate the NDK basics. Next, we try a hello-world build just to make sure everything is set up correctly.

First, we provide the info where to download the NDK libraries, how to install them, and what components to verify before you start. In this tutorial, we try to cover the fundamental steps required in NDK development and point out the key resources to further explore the advanced aspects of the toolsets. It also comes in handy for those who simply want to incorporate some existing libraries done in other computer languages other than Android’s own without re-inventing the wheel. Usually, developers who consider fine-tuning the device performance or implementing apps with computationally-intensive operations will need to look into this option. However, it is certainly not for everyone, considering the knowledge and complexity involved. In addition to the Android Software Development Kit (SDK), NDK is Android’s Native Development Kit that provides the option for the support of integrating native coding development from other computer languages such as C, C++, Kotlin, and so on.
