I created main.c in my jni folder with the following contents which simply returns a java string when the method is called. We need to create a *.c file where we will write the function body for the method. Ignoring the #define statements, this file contains a function prototype that matches the native method that we defined in our java code. JNIEXPORT jstring JNICALL Java_com_example_demoproject_MainActivity_getStringFromNative * Class: com_example_demoproject_MainActivity #define com_example_demoproject_MainActivity_MSG_RESUME_PENDING 2L #undef com_example_demoproject_MainActivity_MSG_RESUME_PENDING #define com_example_demoproject_MainActivity_MSG_REALLY_STOPPED 1L #define com_example_demoproject_MainActivity_BIND_ALLOW_OOM_MANAGEMENT 16L #undef com_example_demoproject_MainActivity_BIND_ALLOW_OOM_MANAGEMENT #define com_example_demoproject_MainActivity_BIND_ADJUST_WITH_ACTIVITY 128L #undef com_example_demoproject_MainActivity_BIND_ADJUST_WITH_ACTIVITY #define com_example_demoproject_MainActivity_BIND_ABOVE_CLIENT 8L #undef com_example_demoproject_MainActivity_BIND_ABOVE_CLIENT #define _Included_com_example_demoproject_MainActivity #ifndef _Included_com_example_demoproject_MainActivity * Header for class com_example_demoproject_MainActivity */ * DO NOT EDIT THIS FILE - it is machine generated */ Running this successfully with generate a folder called jni with a file _MainActivity.h. javah -d jni -classpath /platforms/android-23/android.jar:/extras/android/support/v7/appcompat/libs/android-support-v7-appcompat.jar:/extras/android/support/v7/appcompat/libs/android-support-v4.jar././build/intermediates/classes/debug. (Windows users replace forward slashes(/) with back slashes (\) and colon separators (:) with semi colons( )). Next, invoke javah using the following command (Replace and to match your own path). Using the terminal window at the bottom of the screen, move into the src/main/ directory using the cd command cd src/main

We fix this by first generating the appropriate C/C++ header files using the C Header and Stub File Generator - javah. This will compile and generate some necessary class files.Īndroid studio will mark this as an error because we don't have the corresponding JNI method defined yet. Save and build your project by selecting Build > Make Project public static native String getStringFromNative() This is an abstract method with the native keyword. To begin, add a native method to your class file.

In order to invoke native C/C++ code in your application, you have to use the Java Native Interface (JNI). In the SDK tools tab, scroll down the bottom of the page and select Android NDK and then click apply to install. Or from the tools menu Tools > Android > SDK Manager You can access this through File > Settings > Appearance & Behavior > System Settings > Android SDK`

Now that you have a new project, you need to download the NDK using the SDK manager built into Android studio. Now just select the defaults for everything else, by hitting Next until the project is created.

As well as the Different form factors- Android Wear, TV and Auto.
Next you have to select a minimum SDK or Android version which your application will support.
Select an application name and company name (this will be used as the package name, so you company domain name should be used). This is done by selecting Start a new Android Studio project in the Quick Start menu when you first launch android studio. I'll also be using the older deprecated NDK plugin rather than the new experimental version. This tutorial was put together using Android Studio 1.4.1 with the most recent API version 23. Getting the NDK up and running on the other hand can be a pain. Android allows you to compile and execute native code written in C/C++ for increased computational performance.
