How to get one-meter location-accuracy from Android devices (Google I/O '18)
Recent changes in industry standards and practices enable up to 10x location-accuracy improvements. This talk will explain when and how developers can get or create high location-accuracy from Android devices, going over timelines, technology, and API details. This includes outdoor location (based on GPS) and indoor location (based on WiFi). It will also feature a demo where a person navigates around a room using an Android phone with WiFi RTT location.
