Typography, Ice Cream Sandwich introduced a new type family named Quickly understand a screen of information. Successful deployment of these tools is essential to help users Such as scale, space, rhythm, and alignment with an underlying grid. The Android design language relies on traditional typographic tools While you can bundle your own fonts with your application and use them via setTypeface(), bear in mind that font files are big and, in some cases, require licensing agreements (e.g., Helvetica, a Linotype font).
