How to change app text or background color in Android Studio?

I'm new to Android development.

I have installed Android Studio Panda 3. The default "Empty Activity' app displays the "Hello Android!" text properly on a USB-connected tablet with its black text and white background.

When I create a virtual device then I don't see the text. This might be because this virtual device has a black background.

Can the text and/or background color for the app be changed in the main .kt file, or perhaps in one of the xml files?
