I went through the same problem and I have just fixed using the following steps:

• Delete the *.zip files from the folder:

C:\Users\YOUR_USER\AppData\Local\Xamarin\zips\

• Delete the folders starting with "Xamarin.Android.*":

C:\Users\YOUR_USER\AppData\Local\Xamarin\Xamarin.Android.*

• Navigate to the directory of your solution and delete all the "bin" and "obj" folders

• Make sure you have the latest Java SDK. In my case the latest one is JDK 1.8:

C:\Program Files\Java\jdk1.8.0_111

• In my case I didn't have the latest java SDK so I searched in google for "Java SE Development Kit Downloads". It took me to the Oracle website page about "Java SE Development Kit 8 Downloads". I downloaded the file "jdk-8u111-windows-x64.exe" (194.64 MB). After the installation it created a folder "C:\Program Files\Java\jdk*\".

• Make sure your Xamarin is pointing to this JDK:

In the Visual Studio go to "Tools -> Options -> Xamarin -> Android Settings -> Java Development Kit". In my case I set it to "C:\Program Files\Java\jdk1.8.0_111"

• Now you should right click in your solution and "Clear solution" and after that you should "Rebuild Solution"

I hope it helps.
