I have downloaded the fonts. But i cant use it. I'm using android, Samsung S3. How do i install it into my phone and use it?

Have you tried this:http://www.google.com.sg/search?ei=_6Z-UurkMM-24AOJxYHYDA&q=install+fonts+on+android&oq=install+fonts+on+android&gs_l=mobile-gws-serp.12...0.0.0.26937.0.0.0.0.0.0.0.0..0.0....0...1c..31.mobile-gws-serp..0.0.0.JO5KP-lv2qY

I have that app. Do i have to use that app in order to install these fonts? How?
