Ken Cecka's native android patch http://exult.sourceforge.net/forum/read.php?f=1&i=348367&t=348367 was only saved to Dropbox and its file sharing rules changed so the link to the patch is no longer valid. The last version is now attached to this patch request for archival purposes.
It likely won't apply right away since Exult's sorce changed since then, especially indentation.
exult-svn-androidorig-all.patch is the updated patch by Mark Balfe from 2013
Ken is in the midst of getting his new and improved fork of Exult merged on github. Closing this old patch.
