Porting SDL3 game to android

Question

I've been trying to port my SDL3 game to android, the application builds, but upon opening the application it crashes immediately, I looked into logcat and it prints this error: Error

It seems like it cannot find SDL, even though I've specified the path to SDL in local properties, and It uses an SDL library to build. SDLActivity:

    protected String[] getLibraries() {
        return new String[] {
            "c++_shared",
            "SDL3",
            "loader",
            "image_engine",
            "image"
        };
    }

local.properties:

sdk.dir=/home/koogel/Android/Sdk
sdl3.dir=/home/koogel/SDL/
cmake.dir =/usr/

build.gradle

//adding of the SDL3 directory
Properties properties = new Properties()
properties.load(project.rootProject.file('local.properties').newDataInputStream())
def sdl3Dir = properties.getProperty('sdl3.dir')
if (sdl3Dir == null)
{
    throw new IllegalArgumentException("no [sdl3.dir] property in [local.properties] file")
}

This is actually a second time I'm reworking this project as the last time the project was built with deprecated functions and was based on the example, now I want to make my own project

Answer 1

The issue was with the name of the namespace, the namespace should've been org.koogel, instead of koogel.
