How do I "use a Theme.AppCompat theme"?

[Rodney McKay]

I'm just getting started with Kotlin, and trying to follow this tutorial

https://developer.android.com/codelabs/camerax-getting-started#2

But it doesn't work.  I'm getting the following error (along with many others, but this is the first one and appears to be the cause of the others).

"Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity."

Adding "import androidx.appcompat" to MainActivity did not solve the problem, just caused a different error.

The solution is, instead of 

1. In Android Studio, create a new project, and select Empty Activity when prompted.

do
       1.  In Android Studio, create a new project, and select Empty _View_ Activity when prompted.

As of Android Studio Flamingo, starting the project as an "Empty Activity" will not create the file activity_main.xml in the location where this tutorial expects it.

Also, in "MainActivity.kt," make sure the import statement

"import com.example.cameraxapp.databinding.ActivityMainBinding"

does not include "android" in it.
