This article mainly introduces the construction of JNI and NDK environment variables, as well as the installation of CMake tools and ndk-build tools.
1. JNI environment
JNI is part of Java, so you only need to build a Java environment to have a JNI environment. You can find tutorials online for installing Java environment, and there are many blogs about installing JDK. My computer is installed and environment variables are configured:
2. NDK environment
Local development kit: Download through AndroidStudio: SDK Manager->SDK Tools->NDK
3. Installation of CMake tools
CMake is downloaded through Android Studio: SDK Manage -> SDK Tools ->CMake
4. ndk-build tool installation
After installing NDK in the third step above, it comes with the ndk-build tool. Therefore, my computer already has the ndk-build tool.
