Usage

From source file:com.kentli.cycletrack.RecordingService.java

public void startRecording(TripData trip) {
    this.state = STATE_RECORDING;
    this.trip = trip;

    curSpeed = maxSpeed = distanceTraveled = 0.0f;
    lastLocation = null;//w w w .j a v  a 2  s.  c om

    // Add the notify bar and blinking light
    setNotification();

    // Start listening for GPS updates!
    lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);

    // Set up timer for bike bell
    if (timer != null) {
