If you’re a Flash developer who’s interested in Android mobile development then check out my two-part tutorial – Build a GPS Speedometer.
The first part is available from Mobiletuts+ and covers the basics of AIR for Android development. Part two can be found on Activetuts+ and ensures that you come away from the tutorial having built and deployed onto your mobile a fully working app.
Don’t worry if you don’t have an Android device, you can still follow the steps and test on your desktop using the GPS data that’s provided with the source code. There are some tips and tricks for mobile optimization scattered throughout the second article too.
Hope you find it useful and all feedback welcome.
