In Android Studio, I'm adding a Pixel 4 virtual device. It asks me to select a
System Image, and has the following one selected by default:
Release name: Pie API Level: 28 ABI: x86 Target: Android 9.0 (Google Play)
There are others with API levels 29 and 30 that are shown but that I haven't downloaded yet. How do I decide which System Image to use for a Pixel 4?
