Thanks so much for your help Ian. I just uninstalled an Oracle virtual machine, uninstalled Corretto, rebooted, deleted all Corretto program files, downloaded a newer version of Corretto and installed it, and then continued with the instructions in the PDF. It seems to be working! I’m able to make a hymnal app, build it, and install it on my phone.
During the final RAB installation instructions, this line showed up several times in the command prompt window:
Warning: File C:USers\larkale\.android\repositories.cfg could not be loaded.
Is this significant? What problems could come of this?
Thanks so much.
