The font is not displayed on the device, how to fix it?

Question

Android

In the Font folder there are 2 files with fonts amita.ttf, roboto. On the TextView via Design in the fontFamily field set the value @font/amita, in Design the font is displayed but not on the device, what could it be?

Answer 1

In the designer api level 27. This is the api in which support for fonts in xml has appeared. The device probably works on an earlier version. Therefore, it doesn't work. You need to use the support library. https://developer.android.com/guide/topics/ui/look...
