@ -82,6 +82,23 @@ For more complex projects, follow these instructions:
4b. If you want to build manually, run './gradlew installDebug' in the project directory. This compiles the .java, creates an .apk with the native code embedded, and installs it on any connected Android device
If you already have a project that uses CMake, the instructions change somewhat:
1. Do points 1 and 2 from the instruction above.
2. Edit "<project>/app/build.gradle" to comment out or remove sections containing ndk-build
and uncomment the cmake sections. Add arguments to the CMake invocation as needed.
3. Edit "<project>/app/jni/CMakeLists.txt" to include your project (it defaults to
adding the "src" subdirectory). Note that you'll have SDL2, SDL2main and SDL2-static
as targets in your project, so you should have "target_link_libraries(yourgame SDL2 SDL2main)"
in your CMakeLists.txt file. Also be aware that you should use add_library() instead of
add_executable() for the target containing your "main" function.
If you wish to use Android Studio, you can skip the last step.
4. Run './gradlew installDebug' or './gradlew installRelease' in the project directory. It will build and install your .apk on any
connected Android device
