To work with Android under Xamarin you have to set up Android SDK and JDK path under Tools->Options->Projects->SDK Locations->Android I faced a problem after setting all SDK locations it says "SDK not found" for JDK despite giving the correct path for JDK installed on my system. After few hit and trials I figured out that the problem is 64-bit version of JDK installed . Xamarin works with 32 bit JDK. So I downloaded the 32-bit version of JDK from http://download.xamarin.com/Installer/MonoForAndroid/jdk-6u39-windows-i586.exe After installing this JDK I set up the options for SDK locations and now Xamarin works fine.
I document random stuff on this Blog. It can be a piece of code , my personal experience, a fun fact or anything else.
