James Ward and I collaborated and wrote a simple demo app called "Scribbler". It demonstrates some really simple concepts such as detecting screen capture and saving to the local file system on Android. This application is a regular Flex applications that uses standard Flex 4 components (Not the new Hero/Slider framework) hence demonstrating that in some cases you can use MXML to build mobile apps. The application is available now on the Google Android Marketplace. We made this lame icon with "Sp" based on an indecisive moment of what to call the damn app. If you end up having to explain it to someone say SP stands for "Sribbler Pad".
