I have tried using Typeface.createFromAsset(getAssets(),"font/myfont.ttf"));
I know font directory should be in assets but in my case, I have an existing font resource directory so I thought asset manager will read from font resource directory but I was wrong. I am creating Typeface to set custom font for collapsingToolbarLayout.
I found this answer but it requires me to keep font in assets
This worked
Typeface typeface = ResourcesCompat.getFont(this, R.font.app_font);
Found this in the tutorial link by @Eselfar
