Compass for easy usage!

So it took me a long time to do the compass so i figure to help any and all who want to use it here is how to get the azimuth for your phone.

this is the basic beginning part and will need more but a great start to figuring out the on board compass.

public void onSensorChanged(SensorEvent event) {

if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER)
mGravity = event.values;
if (event.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD)
mGeomagnetic = event.values;
if (mGravity != null && mGeomagnetic != null) {
float R[] = new float[9];
float I[] = new float[9];
boolean success = SensorManager.getRotationMatrix(R, I, mGravity, mGeomagnetic);
if (success) {
float orientation[] = new float[3];
SensorManager.getOrientation(R, orientation);
azimut = orientation[0]; // orientation contains: azimut, pitch and roll
converter = azimut;

}
