I am trying to test an app in Android Auto, and I'm setting up the desktop head unit. I have followed the directions - the phone is in developer mode and the Head Unit Server is running. I also have the DHU on my host macbook, but I cannot get it started.
$ adb forward tcp:5277 tcp:5277
5277
$ ~/.../desktop-head-unit
Connecting over ADB to localhost:5277...failed to resolve: nodename nor servname provided, or not known.
Failed to start Google Automotive Link.
Sometimes it is associated with the DHU window appearing, but being entirely solid black, and my mac doing the spinning beachball thing. Other times I see nothing at all appear.
As far as I can tell, adb is trying to connect but the DHU possibly isn't specifying a host. A similar error message appears if I try and use adb connect without specifying a host.
I have also tried adb reconnect. adb kill-server and then adb start-server before rerunning the commands. I also tried adb install to see that installing an apk still works, and it does.
