I am pretty new to LiveCode, although I was a SuperCard programmer, back in the day.

I am a teacher and would like to get my students to design apps using the Community Edition of LiveCode. But, I cannot get the Android emulator from the Development kit to work. I have careful followed all of the steps of the various lessons, and searched the form for hints, but no luck.
I have the emulator running (a Pixel 3, for what it's worth). But, the Test Target remains greyed out. I wonder if it is because the JDK path is none. But, my understanding is that it is supposed to populate on its own. Well, it's not working for me. I do have Java 8 installed. I'm not really sure what to do. I appreciate any help that can be offered.
