- I'm not sure how much of this is actually true, but Lebron James's move back to Cleveland was leaked by... HTML color codes on his website. Whether true or not, be careful what you put into production, I guess!

I'm continuing my adventures into mobile development this year. I've spent a lot of time on Windows Phone 8 so far, and as I'm writing this post, I've shipped an app off to a couple of friends to try on their real phones.
Next step, since I'm using MvvmCross, is to take that codebase and use (most of) it to create an Android version of the same app using Xamarin.
I've done Android development before, both with plain Java and with Xamarin (called MonoDroid way-back-when), and either way a major pain point has been the Android emulator. It's slow, clunky, and cumbersome, and everyone knows it. Fortunately, Greg Shackles, Xamarin MVP and all-around great guy, heard my whining and recommended that I check out Genymotion (which I had never heard of).
And, behold! Genymotion is just what I've always wanted. It can create and spin up Android emulators for me using VirtualBox. The prices are very reasonble, and there's even a free version that is no slouch!
I installed it, and it was even kind enough to install VirtualBox for me. Once it's installed, you can select from a whole bunch of pre-configured Android devices (Galaxy S4, HTC One, Moto X, etc).
I decided to create a Galaxy S2 image (which is the phone I actually own and use everyday).
Then, just click that "play" button, and a reasonably fast Android emulator will start up. Both Xamarin Studio and Visual Studio with Xamarin discover it, no problem. I assume Eclipse will also be able to find it.
If you're doing Android development, do yourself a favor and give Genymotion a try.
P.S. It's pronounced "Jenny motion"
