Extract the file into a directory that contains no spaces in the path name.For example I use D:\ so the path is D:\android-ndk-r10. For example, MyFile.cpp requires C 11 and must allow exceptions. Step3:Installing the Android NDK Go to the official Android site and download the NDK zip for windows. You can specify optional arguments and flags for your CMake file. On this page Set up your development environment Prepare your device or emulator Open the sample project Run the sample Use Instant Placement. Before we create a JUCE application for Android we need some of the standard tools, Android SDKs, and the Android NDK (Native Development Kit). I downloaded the glm C files I needed (I don’t believe you can use Gradle to manage C or C dependencies the same way you can Java) and stashed them at src/main/cpp/glm, thus include_directories(src/main/cpp/) is needed to include this dependency. Myfile.cpp has OpenGL Mathematics as a dependency. src/main/cpp/Myfile.cpp ) # Add the directories where the Cpp header files are to let CMake find them during compile time include_directories(src/main/cpp/) SHARED # Provides a relative path to your source file(s). ![]() Myfile # Sets the library as a shared library. add_library( # Specifies the name of the library. Press the Apply button and you are all set without the need to worry about the options and installations. The NDK is used to add functions to an Android application by using the C programming language. Switch to SDK Tools and you should see the recommended tools highlighted in Figures 1 and 2. When you build your app, Gradle # automatically packages shared libraries with your APK. In Figure 2, it is the SDK Manager started up by Android Studio when you go to its menu under Tools -> Android. You can # define multiple libraries by adding multiple add.library() commands, # and CMake builds them for you. cmake_minimum_required(VERSION 3.4.1) # Specifies a library name, specifies whether the library is STATIC or # SHARED, and provides relative paths to the source code. # This ensures that a certain set of CMake features is available to # your build. # Sets the minimum version of CMake required to build your native library. ![]() ![]() I am interested in having my Java code communicate with a C file named Myfile.cpp. ![]()
