I have also implemented the AffectButton for use in (native) Android apps.
Of course you could just use the javascript version and display it within
a WebView but the native version performs much better as it
is implemented using OpenGL for Embedded Systems.
A binary containing a demo similar to this one can be downloaded
here. You can
install it on your Android device directly provided you have configured
it to allow packages from other locations than Google Play. Otherwise
you will need the Android Development Kit and use its adb
command to install it on your device via a USB cable.
The code for the Android version is not yet available... I wrote it while employed at ASK Community Systems and will need to clear it with them first. When I get a green light to share the code, I will most likely put it in a separate repository and link to it here, so do check for updates.
