Bike navigation display app

A companion Android application for the wireless bike navigation display.

The app does:

Compose map frames and send them to the display
Import and store GeoJSON tracks, including BRouter routes
Download map areas for imported tracks to work offline
Broadcast step-by-step navigation directions from OsmAnd, which was the original purpose of the display, but turned out to be useless
