Font resource could not be retrieved

Question

I\'m using compileSdk and targetSdk version 27 and in last release I used new font resource feature for my project but after a day I got 3 crashes

Answer 1

Had this same issue, noticed a detail in the docs that helped:

When you declare font families in XML layout through the support library, use the app namespace to ensure your fonts load.

I had been using the 'android' namespace before, changing to the 'app' namespace made my fonts load on older devices correctly.
