Get fonts online , so how can I install font programatically to this folder
thank you
It is not possible to install new fonts without root, the iFont app only works without root on very few devices (please check their app description).
If you developed an app that needs a specific font, you should use the Typeface solution.
The best solution is to ship the font in your app by yourself and work with Typeface, as mentioned by @thiagolr. The easiest solution is to use Calligraphy in your project, so you can apply a custom font in your whole project in an easy way.
