Visual Studio 2017 – Xamarin – The file “obj\Debug\android\bin\packaged_resources” does not exist

I had this same problem

First set build output verbosity using

BTW, I managed to find what’s the problem by setting build output verbosity to Diagnostic in Tools -> Options -> Projects and Solutions -> Build and Run which gives a detailed info why the build failed in the Output window.

Then do a search.

In my case I had

Resources\layout\Main.axml(2): error APT0000: Integer types not allowed (at ‘textSize’ with value ’90’). (TaskId:176)

CRAP! I need to change it to 90sp   (Of course)

grr that wasted too much time.
