I have been working with libgdx for some time. And I know that to load fonts from .ttf files added to the assets folder I can use "FreeTypeFontGenerator".
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(gdx.files.internal("data/samplefont.ttf"));
font = generator.generateFont(12);
generator.dispose();
But I could not find anywhere how to use the fonts available in android. Please help.
