When I enable obfuscation on public members in my Android app, I get a fatal runtime error at app launch when I am using the Android support library.
Here is an example project that is identical to this project, except that I use AppCompatActivity instead of Activity.

The runtime error indicates that something in the appcompat library cannot be found in the apk when obfuscation is enabled.
java.lang.NoSuchFieldError: No static field abc_textfield_search_default_mtrl_alpha of type I in class Landroidx/appcompat/R$drawable; or its superclasses (declaration of 'androidx.appcompat.R$drawable' appears in base.apk)
