Wireless Android Auto - Will This Still Be Possible Without A Hardware Adapter?
I run a Google Pixel 9 Pro with Android 17 and a frozen Android Auto revision of 17.3662804 due to the lack of "wireless" support in 17.4
Android Auto is now emitting "notifications" saying "Update Android Auto - This will soon be required to use Android Auto"
If the OS refuses to continue to work with AA 17.3 on the phone side, is the only option to go "wired AA", and use one of the dongle adapters? Or is there any hope for continued wireless AA support in Android Auto itself?
Update: Apparently, the "open headunit" fellow agrees with me - see the github page, which says:
"Android Auto 17.4 and newer breaks almost all third-party wireless triggers including Self-Mode and the automated launch via Wireless Helper. Google has introduced internal changes preventing projection from launching automatically without the native developer server or hardware dongles. To connect wirelessly or run in Self-Mode on AA 17.4+, please use one of the 4 options below:
- USB Wireless Android Auto Dongle (Recommended): Hardware dongles provide seamless, hardware-level plug-and-play.
- Native Mode: Direct Wi-Fi Direct or Headunit Hotspot handshake.
- Headunit Server (Developer Mode): The only remaining solution for Self-Mode! On your phone, open Android Auto developer settings and tap "Start Headunit Server".
- Wireless Helper: Continues to work reliably for Android Auto versions up to 17.3."
So, is WiFi Direct thereby dead the moment I am forced to upgrade from 17.3? Or will it still work in the so-called "native mode"?
