9/10/2023 0 Comments Eclipse android ndk![]() Take the header file and place it under the “jni” folder. Now create a new folder, call it “ jni” and put it under the project root folder. Next, build the sample Android applications that use the shared libraries: If you are developing in Eclipse with ADT, use the New Project Wizard to create a new. 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: The Android plugin for Eclipse (ADT) now supports NDK-based app development. ![]() Generate C Header File using “javah” command 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). 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. Step 1 : Installing C/C++ support for Eclipse – ADT (Android Plugin for Eclipse – read this article for configuration) Install Eclipse and the Android SDK I am using Eclipse Indigo for this guide. – 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: Here is how I accomplish that so that I have an Eclipse CDT nature within an eclipse Android SDK application project that actually uses the NDK build system and also gets rid of that annoying CDT no gnu makefile at project with all target. You could go through the manual installation steps. So I am using Eclipse 3.5 and Android NDK r4b and need to set up a sample project to test my build scripts. ![]() 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. Android Studio Android SDK Eclipse IDE ADT and CDT plugin for Eclipse Android NDK OpenCV4Android SDK. 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.
