          Yep, I get the same thing. Are you using Qt Creator or another IDE? I too am running on Windows.

          I get these errors when I run your code:

              https://qt-project.org/doc/qtcreator-3.1/creator-quick-tour.html

              Check out number 7, that's where you can see all the different output panes. I clicked on application output and saw the errors.

                It doesn't seem to be seeing your file... strange to me because it works fine on desktop

                    I feel like the file isn't being included when packaged for a Virtual Device. So the question is: How do we ensure a file is being included as part of the package? Obviously I don't know the answer :-(
