And for completeness for the rotation I do the following:
public void onSensorChanged(SensorEvent event) {
RideRouterApp.i(String.format("Sensor Name: %s, oriented %f",
event.sensor.getName(), event.values[0]));
synchronized (this) {
mHeading = event.values[0];
invalidate();
}
}
@Override
protected void dispatchDraw(Canvas canvas) {
canvas.save(Canvas.MATRIX_SAVE_FLAG);
canvas.rotate(-mHeading, getWidth() * 0.5f, getHeight() * 0.5f);
mCanvas.delegate = canvas;
super.dispatchDraw(mCanvas);
canvas.restore();
mapView.invalidate();
}
