When attempting to compile my Xamarin.Android app I get the compile error:
Error 3 The file \"obj\\Debug\\android\\bin\\packaged_resources\" does no
Had the same problem. My error was in the manifest: I had Version Code (Version number) set at "1.0.0" and it wasn't allowed. It only takes integers so I had to revert to "1".
I mixed up Version Code and Version Name.
