Answer 1

我也面临着 FontFamily 方法未找到的相同错误。原因是

TypefaceCompatApi26Impl.class //it's library was missing

通过添加核心库的稳定版本 implementation 'androidx.core:core:1.3.0'( https://developer.android.com/jetpack/androidx/releases/core ) 在 gradle 构建文件中。它为我修好了。
更新:
那些使用 Appcompat 库而不是核心库的人可以使用 Appcompat 库的稳定版本，即 androidx.appcompat:appcompat:1.3.1 ( https://developer.android.com/jetpack/androidx/releases/appcompat#version_131_3 )@Thiago 提到
