So if a user has set his Font Size to Small/Big/Huge, I would like to apply this automaticly to all my text

I am using a Samsung Galaxy Nexus, Android 4.1.2

Thank you in advance for your help

Answer 1

Try reading FONT_SCALE from android.provider.Settings.System.

Answer 2

You can also define your text size using "sp" units which is the same like "dp" but scales according to the users system setting for text size. No need to read the font size from the system yourself.
