Question

Answer 1

I resolved the problem by converting my file.ttf to file.otf

remplace :

Typeface typeface = Typeface.createFromAsset(activity.getAssets(), "fonts/ostrich_regular.ttf");
yourTextView.setTypeface(typeface);

by :

Typeface typeface = Typeface.createFromAsset(activity.getAssets(), "fonts/ostrich_regular.otf");
yourTextView.setTypeface(typeface);

FYI : the .otf format work for all android version (not only on kitkat)
