I have a website developed in GWT/MGWT
I used MGWT widgets, but when I run the application on my mobile everything is really small. I don't think it's the matter of increasing width/height, etc.
You can open it on your mobile and have a look: http://119.154.187.175:8080/dashboard2/dashboard2.html
The viewport doesn't seem to be configured correctly. Try to set
in your entrypoint right at the beginning.
Here is also a getting started: https://github.com/mgwt/mgwt/wiki/Getting-started-with-mgwt
