I am attempting to run a Hello World example from the following tutorial: https://mva.microsoft.com/en-US/training-courses/xamarin-for-absolute-beginners-16182

I am receiving the following error:

Severityjava.lang.UnsupportedClassVersionError: com/android/dx/command/Main  :  Unsupported major.minor version 52.0    HelloXamarin.Droid

I have tried many combinations of JRE/JDK versions. I am uninstalled them, reinstalled them. I have tried JDK 7 and JDK 8. I keep getting this same exact no matter what combination.

The solution not involving using Visual Studio IDE (i.e. build servers) is to import the following key to the registry after installing JDK version 1.8.0_101:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Novell\Mono for Android]
"JavaSdkDirectory"="C:\\Program Files (x86)\\Java\\jdk1.8.0_101"

Don't forget to clean/update sdks.cache files in obj[Release|Debug] directories to reference the correct version of jdk.

For the reference here is a complete list of paths used by Mono for Android:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Novell\Mono for Android]
"AndroidNdkDirectory"="C:\\ProgramData\\Microsoft\\AndroidNDK\\android-ndk-r11c"
"AndroidSdkDirectory"="C:\\Program Files (x86)\\Android\\android-sdk"
"JavaSdkDirectory"="C:\\Program Files (x86)\\Java\\jdk1.8.0_101"

I had a similar issue when Xamarin.Android project was moved from Xamarin Studio (Mac) to Visual Studio 2015 (Windows 10).

I resolved this issue after JDK 1.8.0_121 (for Widows x64) installation.

It worked also for me ONLY changing the registry entry
