error reading file skin.json libgdx

Question

I am trying to create a main menu for a game that my friends and I are are attempting to make. We work with Eclipse + LibGdx, and I genuinely have no idea what I am doing. I am using code directly from, and I have been unable to find any help on any blog/forum/tutorial.

Answer 1

Font file not found: Razer.fnt

You have to use Hiero tool to create a Font. Put the two files generated in android project on Assets folder. If you dont have the "Razer font", search in some font site

Answer 2

That error is basically saying there's something wrong with the skin json.

The format though seems pretty fine, however I think there is more in the stacktrace. Please check out the path to Razer.fnt.

If that doesn't fix it, paste here the full stacktrace.
