Do I need to use Roboto font and put it to asset folder if my app will support only Android 4+ devices?

android:fontFamily="sans-serif-medium" // roboto medium
And so on.
This comment adds no more than Ahmad’s, but just clears up that you are not limited to the 3 examples he gave, you can use any.
Ice Cream Sandwich introduced a new type family named Roboto, created
specifically for the requirements of UI and high-resolution screens.
