I am a beginner in the world of mobile development, I downloaded Xamarin Studio (Mac) to start programming apps for the three environments, but I have a problem, I think, with the Android SDK.
The first time I created an Android app, when I wanted to look at the interface in Main.axml, I missed a window that said something like the SDK was old and needed to be updated to version 25.0.2, it seems to me. I opened the SDK Manager, and downloaded all the Extras, the latest version of the Android SDK Tools, the Android DSK Build Tools, and the Android SDK Platform, and the entire Android 6.0 pack. Now the designer works, but when I compile the application this error arises:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: java.lang.UnsupportedClassVersionError: com / android / dx / command / Main: Unsupported major.minor version 52.0 (TestAndroidXamarin)
