Good progress - Mixtikl's Audio is now working under the Airplay ARM simulator, so I now need to get it all up-and-running on an actual Android device. Fingers crossed. :)
Edit: Mixtikl is running under the Android simulator using Airplay - amazing. :-D
Many congratulations to Ideaworks!!

Airplay SDK - building C++ apps as Android .apk files - first impressions
I noticed the other day that the Airplay SDK now uses modern C++ with STL - nice, and essential for my code. I already knew that the Airplay SDK supported Android, and having taking a look at my Android porting options I really didn't want to directly port my own C++ app code to Android using STL and JNI - there would be too much pain involved. :-0
So, having just installed the latest Android SDK on Windows 7 and Mac, I figured it was time - finally - to download and install the Airplay SDK evaluation.
In installed the Windows version on my Mac under Boot camp. This requires Visual Studio 2008 (the Express edition should work, if you're interested...).
Installation on Windows was easy, the eval license registered properly and I was soon following the instructions to build my first basic demo project. [I actually started with the Mac version - still in Beta - but it failed to register my eval license! Serves me right for starting with Beta software :)]
I double-clicked the example project file for a 3d demo game, which automatically constructed and opened a suitably configured Visual Studio project. Building this for the x86 target was as easy as building any other Visual Studio project - very simple.
Running-up the project under Visual Studio debugger for Windows, ran the app through a device emulator, which worked smoothly.
I next trivially rebuilt the app for ARM Debug target, ran under Visual Studio under ARM emulator on Windows - again this was easy and worked fine - it runs the app through an arm device Emulator, with a graphical version of GDB as the debugger.
Having rebuilt the app for ARM Release target, I next used a simple utility that comes with the Airplay SDK, to bundle-up the app an a .apk file (the installer format for Android). This was really easy. Note, however, that I first had to rename the Android SDK 1.6 folder on my PC (see the Airplay SDK forum for details on how/why!), and had to install a couple of other tools that are clearly documented in the Airplay documentation). Anyways: once your system is configured, building the .apk file is very easy. :)
I next installed the .apk to the Android SDK's emulator using the "adb install" command, and ran-up the application directly from Android SDK emulator. This worked OK, albeit with a slow frame rate I've been told that on devices the frame rate is very, very much faster than the emulator).
So, a really good experience so far. I'm looking forward to finding out more in due course. I was impressed enough to get a 99 dollar "indie" license; the "iPhone" license is actually free, which is very cool.
I'll need to find out how well it all works on a real Android device, and try some complex 2D graphics and heavy-duty audio, but the Airplay SDK so far looks very promising. It is powerful enough that it even looks like it'd be relatively straightforward to port frameworks like Qt to the Airplay SDK.
I found the online documentation to be a pain to navigate, but the documentation in Windows CHM file format (in the SDK) is pretty good.
The bottom line for me is how easy it was to get from generic C++ code, to a .apk file for Android - very impressive indeed. Not only that, the SDK supports buildling Symbian .sis files, Window Mobile .cab files ... and various other platforms. Plenty here to keep me busy and productive!
Edit: I've just discovered that Airplay doesn't support threads at the moment... which is problematic, to say the least!
Edit: I've heard via the Airplay forums that Thread support is coming in a few months ... which is very good news. :) Meanwhile, the port of Mixtikl to Android/Symbian via Airplay (and also a port of Mixtikl via Qt...) is coming along well, so maybe we'll have something to report in a few weeks...
