Daniel Nugent called this shot: at the bottom of the left-hand pane is an option called "Gradle Scripts". My first one was named build.gradle (Project: MyFirstApp), and my second build.gradle (Module: app). Double-clicked on the second one and changed "compileSdkVersion 22" to "compileSdkVersion 23", then attempted a rebuild which failed. The question Daniel Nugent referred to also mentions ensuring I have "Android M libraries" and points to a button on the Toolbar to start the SDK manager; that showed that an update "was available" for Android 5.1 (Lollipop). I couldn't figure out how to update from that window; I guessed at clicking on a link in that window (at the bottom) saying "Launch Standalone SDK Manager", and updated from there (which took a LONG time - 15-20 minutes).

Then the rebuild on Gradle succeeded and running the application (which took perhaps a minute or a minute and a half, longer than I expected) produced the expected window to pick a device, etc. The emulator then ran the "Hello, World" app as desired.

My thanks to all who responded; now if I can just figure out what's wrong with the debug driver for my Galaxy s5...
