Error loading json ui-skin file from android/assets

Question

I have default.json file for setting skin to ui component. The file location previously was in project package core/src/com/mygame, which has the following data:

{
  com.badlogic.gdx.graphics.g2d.BitmapFont: {
    default-font: {
      file: Razer.fnt
    }
  },
  com.badlogic.gdx.scenes.scene2d.ui.TextButton$TextButtonStyle: {
    default: {
      up: default-round,
      down: default-round-down,
      font: default-font
    },
  },
  com.badlogic.gdx.scenes.scene2d.ui.Window$WindowStyle: {
    default:  {
      titleFont: default-font
    }
  }
}

Then I would load that file in onCreate method skin = new Skin(Gdx.files.internal("default.json")); Which is working.

However, now I decided to move that file to android project in assets folder called ui-skins/. Problem is, I'm getting an error when I try to load that file from path Gdx.files.internal("ui-skins/default.json"):

Did you forget to also move Razer.fnt into the same `ui-skins/` directory in the android assets directory? — Tenfour04, Jun 07 '16 at 18:13

I found your error:

Font file not found: Razer.fnt as stated in the error log.

Remember, that you need your font.fnt file AND your font.png file in the same folderstructure, as it was before(I guess in the same folder, as your JSON file).

Hope that helps

€dit: Further explanation as why you need the font.png
If you look into your .fnt file you'll see, it's only text, which describes the .png of your font. in this .png are the glyphs.

test your json here

you need to put your strings inside quotes, like this:

{ "com.badlogic.gdx.graphics.g2d.BitmapFont": { ...

Unnecessary in LibGDX. The LibGDX Json parser is designed to not need quotes. – Tenfour04 Jun 07 '16 at 18:12
