This video describes one way that address data can be collected and added to OpenStreetMap. There are many ways of collecting the data and I went through a number prior to settling on this technique.

OSMTracker: f-droid.org/en/packages/net.osmtracker/
KeypadMapper2: github.com/cobra/KeypadMapper2
GpxAnimator: github.com/zdila/gpx-animator
