I don't wanna mention names as I'm sure I'd forget someone so I just tell where help has been done: - The partial android versions done by various ppl - Testing on different android devices - reviewing code (especially the in core changes) - testing controls - reviewing texts A big thank you to everyone helping this to be completed! --- src/porting_android.cpp | 295 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 295 insertions(+) create mode 100644 src/porting_android.cpp (limited to 'src/porting_android.cpp') diff --git a/src/porting_android.cpp b/src/porting_android.cpp new file mode 100644 index 000000000..96c9385a6 --- /dev/null +++ b/src/porting_android.cpp @@ -0,0 +1,295 @@ +/* +Minetest +Copyright (C) 2014 celeron55, Perttu Ahola + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU Lesser General Public License as published by +the Free Software Foundation; either version 2.1 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
