![]() ![]() Take the header file and place it under the “jni” folder. The NDK works with the basic stand-alone SDK Tools, and also with the Android Studio IDE or with the older Eclipse ADT IDE. Android offers a custom plugin for the Eclipse IDE, called Android Development Tools (ADT). Now create a new folder, call it “ jni” and put it under the project root folder. after this step you will be able to see the header file placed under the “bin/classes” folder. Go inside the “bin/classes” (there is where you will find the compiled class) and execute Javac src/com/android/ndk/example/NativeCode.javaĪfter that we will execute “javah” command with the parameter “-jni” to create the header file: Open the Windows console and execute “javac” command to compile the class inside which we have defined the native C method and specified that we want to load a binary library: Generate C Header File using “javah” command ADT extends the capabilities of Eclipse to let you quickly set up new Android projects, create an application UI, add packages based on the Android Framework API, debug your. The “getString()” is the name of the native method that we will use later in the application and “androidndk” is the name of the binary library (it will be specified later in the Android.mk file). Android Development Tools (ADT) is a plugin for the Eclipse IDE that is designed to give you a powerful, integrated environment in which to build Android applications. Check “Eclipse C/C++ Development Tools” and press “Next “ for the installation part: You should be able to see “Programming Language” branch. ![]() In the “Work with” section choose “Kepler” as update site (I use Eclipse Kepler, in case you have another version please look for the right site’s name that match your IDE version’s name) and wait until the item tree loads. Look for “Install New Software” option and click it to open the Install Window. Open Eclipse and choose “Help” item from the menu. You could go through the manual installation steps. Step 1 : Installing C/C++ support for Eclipse Android Studio Android SDK Eclipse IDE ADT and CDT plugin for Eclipse Android NDK OpenCV4Android SDK. – ADT (Android Plugin for Eclipse – read this article for configuration) – Android SDK (if you do not have it installed on your machine you can get it from the official Android site ) – IDE (for this tutorial we are using Eclipse – if you do not have an IDE installed on you machine please go to and get the latest version on Eclipse ) – Java (JDK) (otherwise visit and get the latest JDK and install it to your machine) Until you proceed the steps for installing the Android NDK on your machine please check if you have installed the following features: It can be created using Eclipse wizard or android tool from Android SDK. The purpose of this tutorial is to show you how to use this toolset to create an Android Project that makes a simple call to native C/C++ code. The main article about using Android NDK build system you can read in the file. Android NDK is a toolset that allows developers to implement parts of the application using native-code languages such as C and C++ in order to reuse existing code libraries written in these languages. ![]()
