Put this one squarely within the “that is area of interest” class, however it’s nonetheless a factor. Android N Developer Preview four retains Google Maps from working correctly in Android Auto.
Some in our forums word that it is solely navigation that is not working. Others of us cannot get it to correctly launch in any respect on the top unit.
And it seems this can be a recognized factor. From the support and release notes:
The model of Google Maps included in Developer Preview four (9.30) crashes when used with Android Auto. This problem might be fastened within the subsequent replace to Google Maps (9.31), anticipated within the coming weeks.
So there’s that. When you completely rely upon Google Maps and Android Auto to go about your day — and also you’re operating the Android N DP4 — it may be time to roll again. And keep in mind that it is a developer preview.
