sdl2 windows and android

[djoker]

hello friends,
in recent months I have worked with in sdl2 with freepascal on android compiled from (http://www.pilotlogic.com/sitejoom/index.php/codetyphon) this way came to the conclusion that Native give me better results than java.
I compiled sdl2 sdl2_image sdl2_mixer and sdl2_ttf all in one dll for Windows and separate (.so) for android.
the next step is to compile for Ubuntu .
on this pack i have one demo using sdl2 sd2_image and sdl2_ttf on my experia x8 have 55 fps
and 20 on BlueStacks.

my game (sdl + glEs) (200 particles and tile map) on my device i have 45 fps

Wow that's nice. I would like to know more about how to work with SDL2 and Android with Free Pascal. Maybe there is the chance for a how-to?

Fantastic !!
I'm going crazy to try compile SDL2 with DelphiXE5 for android but I can not
When I add cdecl; external 'libSDL2.so' to any function app not run, say "application has stopped".
I test too many "libSDL2.so" and with all app not run

Kotai.

kotai I prefer open source programs i have no money to buy delphiXE
and if you look to sdl you have to make some trick to work with delphi you have 2 ways
declare android hidden functions from sdl on delphi or expose the native code on delphi jni functions look to my demo.



procedure Java_org_libsdl_app_SDLActivity_nativeInit(env:JNI Env; cls:jclass; obj:jobject);stdcall;

begin
SDL_Android_Init(env,cls);
SDL_SetMainReady();
sdlMain();
logmsg('all ok Luis Santos AKA Djoker');
halt(0);
end;




exports
JNI_OnLoad,
JNI_OnUnload,
Java_org_libsdl_app_SDLActivity_nativeInit;

begin
end.

on the c++ you have the code android_main with this 2 calls look the source code.
and you have to see one point delphixe5 create native libs with 14,9 MB (15.713.020 bytes) on release mode? man wtf . no way
goto freepascal

hi kotai i (download xe5) and try with the sdl2 but i think its not possible because with xe5 you don't have way to use java and sdl2 use java for video , audio and input.
but i think with xe5 you don't need sdl because with xe5 you have all the stuff like glES input ...
