Answer 1

I was also facing same error of FontFamily's method not found. Reason was

TypefaceCompatApi26Impl.class //it's library was missing

By adding stable version of core library implementation 'androidx.core:core:1.3.0' (https://developer.android.com/jetpack/androidx/releases/core) in gradle build file. It got fixed for me.

UPDATE: Those who are using Appcompat library instead core library can use stable version of Appcompat library i.e. androidx.appcompat:appcompat:1.3.1 (https://developer.android.com/jetpack/androidx/releases/appcompat#version_131_3) as mentioned by @Thiago

Answer 2

By upgrade the appCompact libery to:

implementation 'androidx.appcompat:appcompat:1.2.0'

Has fixed my issue (same as yours)

Answer 3

In my case I was forgotten my IDE in "Offline Mode" and the cache was cleared. So on app load custom fonts were missing and couldn't downloaded. By openning Offline Mode from Gradle -> Toggle Offline Mode, I was able to run my app successfully.
