Google Maps Android update expands search-along-route, adds popular-place notifications
In those cases we just described, convenience is key, and we don't want to be going really out of our way and getting off-track from out main route. That's why last year Google Maps introduced a search-along-route option that could help you find things like gas stations or cafes while on another trip. It was a welcome addition, but the feature had one major limitation: it only worked in driving mode.
With Google Maps v9.26.1, the app corrects that oversight and allows users to do the same thing while bicycling or on foot.
Beyond that improvement, the new app makes a few minor UI changes, and adds an option to deliver notifications to let you know about popular places (or those that have been recently added to Maps) that are in your local area.
A closer look at the app also helps shed some light on possible upcoming features that Google's already started laying the groundwork for, but has yet to implement. Those include an offline mode extension that could preemptively warn you when you're about to travel through an area of poor cellular coverage and could benefit from loading those maps to your phone in advance, and a “Discover” tool that would offer destination suggestions based on your usage history.
There's no saying when those in-development features might be ready to go live, but text strings in the new Google Maps app sure suggest they're on their way.
