D SDL Android Project Template

Provides a default/template project for programming with D and SDL on Android This template for my tutorial about how to get your D code working on Android + SDL on Android

As the purpose of this template is to be beginner friendly, I will try to mantain updated:

SDL (2.0.12)

This is a slightly modified version from SDL source code, the only difference at the path SDL2/android-project/app/jni, the folder src was deleted, as there was no need to compile any C code

SDL_Image (2.0.5)
SDL_Mixer (2.0.4)
SDL_TTF (2.0.15)
SDL_Network (2.0.1)

Important notes

This project was made for working on Linux, so, it is untested on Windows, but it should not differ too much

ldc2 and rdmd is a command on your console

Get those commands at Dlang main compilers

You should have modified (dlangPath)/(ldc)/etc/ldc2.conf to include your target architectures, check at my other repo D-Lang On Android

You should have defined on your environment the variable "ANDROID_NDK_HOME"

Execute on a terminal in the current path rdmd setupsdl.d before building anything

If you're on Windows, run this command with admin privilleges

Building

The build system will be a bit different of the main build system for D, which is called dub. The reasoning is for simply keeping your build with some library filtering(for the target Android architectures) The buid command for this project is rdmd build.d Commands supported on build.d

--arch -> Receives the target architecture to compile, default is all.
--help -> Shows every supported architecture.

Modifying build.d

If you need to modify the main build system, it is quite simple to add your own things to it There are arrays definitions for each thing:

Architectures to output, default is:

[
    "aarch64",
    "armv7a",
    "x86_64",
    "i686"
];

Sources for compile, default is:

[
    "source/",
	"bindbc-loader/source",
	"bindbc-sdl/source"
];

Arch Folders: Those are the output folders for each build, default is:

	aarch64 --> arm64-v8a
    armv7a  --> armeabi-v7a
    x86_64  --> x86_64
    i686    --> x86

Output path: ./SDL2/android-project/app/main/jniLibs/
Dependencies, default is:

[
	"BindBC-Loader", 
	"BindBC-SDL"
];

Versions for the compiler, default is:

[
	"SDL_2012",
	"BindSDL_Mixer", 
	"BindSDL_TTF", 
	"BindSDL_Image"
];

Debug, default is: []
Libraries, those are what libraries will be imported from android ndk, default is:

[
    "log"
];

TripleSystem, this is where you will need to change if you're working on Windows on Mac, default is: enum tripleSystem = "-linux-android";

Acknowledgements

LDC team for making the compiler, this project would not be anything without them
https://www.libsdl.org/ for providing SDL
@mdparker for providing BindBC-SDL and helping me on things about compiling
@Joakim for making the initial jni.d lib
@Vild for converting my script into a *.d file
