In design I have a text field with 16 as text size and 0.6 as character spacing
But, if I set this value for android:letterSpacing attribute of TextView spacing will be much more larger than in design.
So, what is the way to convert sketch value to android value?
According to Romain Guy, Android uses the "1 em = font size" definition, so you'd just do
setLetterSpacing(characterSpacing / textSize)
...just make sure those values are in the same unit (dp vs px)
