Answer 1

I followed some of the recommendations from this post for my project using Retrofit:

Unable to get provider androidx.lifecycle.ProcessLifecycleOwnerInitializr

I placed this in my build.gradle

    multiDexEnabled true 
    compileOptions { 
          sourceCompatibility JavaVersion.VERSION_1_8 
          targetCompatibility JavaVersion.VERSION_1_8 
    }

I did get my app to compile. Hope that helps.
