title: Android, Change font size only in one app
body: <p>Is it possible to change the default-fontsize only for one app?
  So i can use the "sp" units at all my fonts?</p>
  
  <p>The problem is that my customer doesn´t wan´t that his employes changes anything in the android-settings. So i am searching for a solution to change the font size in my app. Of course i could implement my own dynamic font size by programmatically changing the size of each label when the user chooses another size. But i think that is to complicated and should by the last way. </p>
  
  <p>Best regards
