How do I debug when "meteor install-sdk android" doesn't work?

I keep receiving the dreaded “error message” that says “Please follow the installation instructions in the mobile guide:”

I’ve followed the instructions, triple-checked everything several times, and installed SDK 23 explicitly in the Android SDK Manager. I’m at a total loss for ideas. What really doesn’t help is that meteor gives me no information at all on what the error was.

Does anybody have suggestions on how to “debug” this?
