Android Question Show compass bearing on Google Map

[Roger Daley]

Hi All,

A two part query.
I am working on a project where I need:
A: to draw a line on a map from a designated point along a designated compass bearing
B: find the compass bearing from one designated point to another designated point.

Before I started calculating "Great Circles" or "Vincenty formulas", I thought there may already exist some function/module that has escaped my searching.

Thanks in advance.

Regards Roger

You can use Location.BearingTo to find the bearing between two points.
