You need SDL2.0
(hg clone http://hg.libsdl.org/SDL)

folders structure:
root\
     oxygine-framework
     SDL
     

how to build. Steps:
- building liboxygine:
  goto oxygine-framework\oxygine\SDL\android\ and run build.cmd
- unpack oxygine-framework\oxygine\SDL\android\SDLTests.zip to the same level with oxygine-framework and SDL
  (to the "root" folder, see example above)
- goto SDLTests\android-project and run makelink.bat. It would create folder link to SDL (see sdl/readme.android)
- run build.cmd.
- run ant_debug.bat
- apk is ready here: SDLTests\android-project\bin !
