Great! Awesome! I've always wanted to write some neat mobile app, but was too lazy to learn Objective-C or Java topped with BlackBerry API or Android. That also meant learning a new IDE. Oh how lazy.
I actually even got myself Eclipse + Android SDK + Java SDK and started to play around with this but then I discovered MonoDroid, a wrap for Android for Visual Studio. I happily tossed away Java and jumped back to .Net.
So, this will give you the start :
It's almost the same Android API as in Java but using the C# syntax and .Net libraries.Enjoy!
