Using Android’s Roboto font is pretty easy on Fedora (or any other Linux flavour). Just download the Roboto zip, open it up, copy the ttf files into your ~/.fonts dir, and refresh your font cache. From there, you can use the font in any program (though you may need to reload it first).
Here are the steps:
``
wget https://dl-ssl.google.com/android/design/Roboto_Hinted_20111129.zip
unzip Roboto_Hinted_20111129.zip
mkdir ~/.fonts
mv Roboto_Hinted_20111129/*.ttf ~/.fonts
fc-cache
``
