How can I proceed to understand the prospect of desktop head unit android auto apk.

steps i used while connecting 1. adb forward tcp:5277 tcp:5277 2. ./desktop-head-unit [Desktop head unit

Answer 1

There's a missing step in the Android docs.

After enabling dev mode within Android Auto app, in the options menu in the top right corner (the same menu where you can turn on the head unit server), there's another option for "Developer Settings". Go there and then select "Application Mode" > Developer. This allowed ADB to successfully connect to my device by running adb forward tcp:5277 tcp:5277 and then executing ./desktop-head-unit (on mac osx)
