Snackbar issue (only in debug mode)

Question

I am having an issue with the Snackbar in the android support design library. The weird thing is, that it only occurs when I run my app in Debug mode, in Release mode it all works perfectly.

Does Anyone have an idea on this issue? It seems to be a bug in the Support library.

Code

using (var snackbar = Snackbar.Make(View, "Nieuwe order aangemaakt", Snackbar.LengthLong).SetAction("OK", v => { }))
    snackbar.Show();

Exception

Answer 1

A simple Clean/Rebuild fixed this issue. Can't believe this wouldn't work a couple of days ago, when I tried that too...
