SLEEP EXERCISE RECORD
ACTIVITY RECOGNITION API EXERCISE
Let’s get started •Track user •Compute distance •Steps measurement
Getting last user’s location //Manifest.permission.ACCESS_FINE_LOCATION private val client = LocationServices.getFusedLocationProviderClient(
activity ) client.lastLocation.addOnSuccessListener { location -> . .. }
Getting updates on user’s location private val locationCallback = object
: LocationCallback() { override fun onLocationResult(r: LocationResult) { // calculate here } }
Getting updates on user’s location val locationRequest = LocationRequest .create().apply
{ priority = PRIORITY_HIGH_ACCURACY interval = 5000 }
Getting updates on user’s location client.requestLocationUpdates( locationRequest, locationCallback, Looper.getMainLooper() )
Compute distances SphericalUtil .computeDistanceBetween( lastLatLng, oldLatLng )
class StepCounter( private val activity: AppCompatActivity ) : SensorEventListener Every
step counts
Every step counts private val sensorManager : SensorManager = activity.getSystemService(SENSOR_SERVICE)
private val stepCounterSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER) private var initialSteps = -1
Every step counts fun setupStepCounter() { if (stepCounterSensor != null)
{ sensorManager.registerListener(this, stepCounterSensor, SENSOR_DELAY_FASTEST) } } fun unloadStepCounter() { if (stepCounterSensor != null) { sensorManager.unregisterListener(this) } }
Every step counts override fun onSensorChanged(event: SensorEvent) { event.values.firstOrNull() ?.
toInt() ?. let { newSteps -> if (initialSteps == -1) { initialSteps = newSteps } currentSteps = newSteps - initialSteps } } override fun onAccuracyChanged( sensor: Sensor, accuracy: Int ) = Unit
