Android Auto not working

[davidep]

This was not working well also on the stock and eragon ROM, but here it doesn't start at all and the car infotainment can't establish a connection. The car can see the device plugged but can't establish any data connection.

If it works through Bluetooth, then I know the problem: Audio Over Bluetooth ist still broken. I already have a fix that I'll push once I release a new version. Thanks for reporting, please let me know if the new version I'll release in the upcoming days works. :+1:

FingerCrossed then :) Even if Android Auto requires a cable connection, bluetooth might be involved as well, so let's see... I'll test the new build and let you know. Thanks ;)

I don't own a car that supports Android Auto (it's a 1990' VW Polo, haha). Could you test if it works in the latest build?

[davidep]

Haha, I tested it again with build n.4 and 4.2 and unfortunately it is still not working. The Bluetooth connection works fine though.

Below the logcat right after the phone was plugged and AndroidAuto executed. 2016-03-14-13-35-28.txt

As with the stock ROM the phone show the AndroidAuto logo in white on the black background, and the car's screen shows just a black screen.

Maybe some permissions missing.

This seems to be fixed now, after installing manually Android Auto 1.6.226040 (2710411-release) http://forum.xda-developers.com/showpost.php?p=66106954&postcount=11

[janengelmohr]

I also just saw it. Can you confirm that it is working now?

[davidep]

Yep, I tested it with build #6 and it worked like a charm :)

[janengelmohr]

Great, I will update the CM post accordingly. Thank you for the investigation!
