How do you retrieve the azimuth of an Android device?

Azimuth is defined by Wikipedia as:

An angular measurement in a spherical coordinate system. The vector from an observer (origin) to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane is called the azimuth.

How can I get this value on Android?

Solution 
  • float [] orientation = SensorManager.getOrientation();
float azimuth = orientation[0];
