What is the method for installing and configuring the Android NDK?
To install and configure the Android NDK, follow these steps:
- Download the latest version of the Android NDK from the NDK download page on the official Android website (https://developer.android.com/ndk/downloads).
- Extract NDK: Unzip the downloaded NDK file into your chosen folder.
- To set environment variables, locate your operating system’s environment variable settings and add the NDK path to the PATH variable. On Windows, for example, you can do this by going to “Control Panel” > “System and Security” > “System” > “Advanced system settings” > “Environment Variables”.
- Set up Android Studio by opening the software, going to “File” > “Project Structure” > “SDK Location”, and then specifying the path of the NDK in the “Android NDK location” field.
- Set up CMake: If you intend to build your NDK project using CMake, you will need to add some configurations to the project’s CMakeLists.txt file. For example:
- Ensure the minimum required version of CMake is 3.10.2 and project name is YourProjectName. Set C++ flags to use the GNU++11 standard. Define the paths to YourProject and OpenCV-android-sdk. Include OpenCV headers and import the OpenCV library. Link the native-lib library with the lib_opencv library.
- You need to replace the paths in the code above with your own project and OpenCV paths.
- Build project: Reconstruct your project to compile and build with NDK.
These are the fundamental steps for installing and configuring Android NDK. The specific steps may vary depending on your operating system and development environment. You can refer to the Android official documentation and other resources for more detailed guidance.
