From 06deeb04cdfd8abea059c6c3c7ecea2565b7a3d4 Mon Sep 17 00:00:00 2001 From: rafal1137 Date: Tue, 6 Nov 2018 12:28:47 +0100 Subject: [PATCH] Added android-project from SDL2.0.9 branch, lets make etlegacy run on all devices running android operating system possible. Still a lot of work to do but we are getting closer.
