On Android available touch devices are now added with video initialization (like
the keyboard). This fixes SDL_GetNumTouchDevices() returning 0 before any touch
events happened although there is a touch screen available. The adding of touch
devices after a touch event was received is still active to allow connecting
devices later (if this is possible) and to provide a fallback if the new init
did not work somehow. For the implementation JNI was used and API level 9 is
required. There seems to be nothing in the Android NDK's input header (input.h)
to implement everything on C side without communication with Java side.
This can break builds of existing SDL/WinRT apps. To fix, remove the reference to SDL_winrt_main.cpp, then add a reference to the renamed file, SDL_winrt_main_NonXAML.cpp. If you get a build error about a missing .winmd file, enable the /ZW compiler flag for that one file (at minimum).
1. remove references to SDL's project files from the Visual Studio Solution. To note, these project files have been renamed, and will show up in Visual Studio with the text, "load failed".
2. add the SDL project files back into the Visual Studio Solution
3. for each project that should link to SDL, add a reference to it. This can be done by right-clicking on it in Visual Studio, selecting "References...", clicking "Add New Reference", checking the box next to the SDL project, then closing each dialog by clicking OK.
SDL_mixer, SDL_ttf, and SDL_image for WinRT have been updated, and will be pushed to my Bitbucket repos with these changes having been made. If you do not pull in these changes, be sure to re-add to them the reference to the SDL project, as described above.
XAudio2 2.8's header file, xaudio2.h, doesn't compile in plain C code for WinRT
apps, not automatically at least. Initially, this file was adapted to compile
as C++, however these changes are now deprecated in favor of some preprocessor
based hacks that should get xaudio2.h to compile (while making sure XAudio2
still works).
This change should allow apps to render correctly in Portrait mode, at minimum,
Support for orientation changes is pending.
Thanks to Pierre-Yves for assistance!
This is part of an overall effort to use the name, "WinRT", rather than "WindowsRT" (or "Windows RT"), as the shorthand name often seems to mean something different than the longhand name. (WinRT is an API, Windows RT is a product name)
