I'm having a problem with all Android C# projects I attempt to Build in Xamarin Studio, including the downloaded HelloWorld app, and blank projects I create from scratch (without adding any additional code).
When I attempt to build or clean any solutions, I get the error "Build Failed." or "Clean Failed.", along with the text "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."
I haven't used Xamarin studio for a few months and now it won't build or clean my old applications, nor allow me to build or clean new ones.
I had found this thread that mentioned the Build Failed error: forums.xamarin.com/discussion/6049/build-failed
So I verified that I am using US English Display Language and System Locale, and I have set Log Verbosity to Diagnostic on the Tools -> Options -> Build page, and nothing changed on the Build Output frame.
I have checked for updates, and I am running the latest version of Xamarin Studio: Version 4.0.13 (build 38). I also tried uninstalling the Xamarin software and reinstalling it, and nothing changed.
At this point, I cannot build any Android projects with Xamarin Studio, and would appreciate any help.
