Wine leader Alexandre Julliard provided a status update at FOSDEM last weekend for Wine on Google Android. The Wine on Android project is still focused upon supporting Windows binaries on Android for both Intel x86 and ARM devices.
Julliard shared that they now have working support for Android's Bionic C library, cross-compilation is supported for Wine on Android with both i686 and ARM architectures, and there's a basic graphics driver using the desktop mode.
Among the challenges that Wine on Android has yielded comes down to dealing with Android's Java focus inside Wine, the Android process architecture, missing libraries not readily available, lack of keyboard and mouse, high DPI displays, OpenGL ES only, and packaging restrictions.
While basic Windows applications are running on Android with Wine, the developers are still working on finishing the user driver, Direct3D and OpenGL application support, audio support, and handling of application launchers and MIME types. All of this Wine Android code also still has to be integrated into mainline.
Wine developers are also experimenting with QEMU support for being able to run the x86 binaries on ARM. This is a feature that has yet to be fully realized, but can be sufficient for running the well known Windows Solitaire program on ARM.
