Most native code is built into libraries for Android applications, but changing the value to $(BUILD_EXECUTABLE) in Android.mk will result in an executable. The final line is the key portion to indicate the building of an executable instead of a library. The LOCAL_SRC_FILES variable specifies the specific source files you’d like to be built for this application/library. The LOCAL_C_INCLUDES variable specifies the directories you want the preprocessor to search for additional include files. This allows you to run the NDK build tools from any other location on your computer without having to specify the tools entire path. The LOCAL_MODULE variable specifies the output name of the binary you’re creating. The line that includes CLEAR_VARS clears existing local variables that might have been set from previous builds or more complex builds that have multiple makefiles. This is initialized to the current directory so that you can use relative paths to other files and directories in the build environment. In Android.mk (Figure 3), you can see that a LOCAL_PATH directory is specified. On Linux*, you can modify the variable for your local shell with the following command: This allows you to run the NDK build tools from any other location on your computer without having to specify the tool’s entire path. Modify your path environment variable to indicate the location of the NDK directory. Follow the instructions to extract and install the NDK on your computer. Check the following options for installation and click OK. Go to and download the appropriate NDK for your OS. From the toolbar, go to Android Studio > Preferences > Appearance & Behaviour > Android SDK > SDK Tools. Setting up your development environment Download and install the Android NDK This article shows how to write a simple “Hello World” application and run it on an Android device using a remote shell.

If the code to be ported is written in ANSI C/C++ and doesn’t have any OS-specific dependencies, it can be rebuilt using the Android NDK build tools and run from the command line in a shell in much the same way you can run command-line apps from the command prompt in Windows. Introduction Other Android NDK API Porting and Using the Existing Libraries with Android NDK Porting an Existing Application to Android with NDK Index You're currently viewing a free sample. It would be preferable to simply port the existing C/C++ code, but many believe that these libraries and tests need to be accessed as Java-based Android applications. When these same features are added to an Android* platform, rewriting these libraries and tests in Java* is a large task. Libraries and test apps are often written in C/C++ for testing hardware and software features on Windows*.
