I’m having the same problem. I created the Android build target anyway, but when I try to build the android package I get this error:
[C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(539,2)]: Error: The “GetJavaPlatformJar” task was not given a value for the required parameter “AndroidSdkDirectory”.
I’m using vs community 2017, and I did install Xamarin using the VS installer. I can’t seem to find a stand-alone installer for Xamarin either, all the download links lead to a download of the VS installer.
Would appreciate any suggestions.
