3. SLEEP EXERCISE RECORD
4. ACTIVITY RECOGNITION API EXERCISE
5. Let’s get started •Track user •Compute distance •Steps measurement
6. Getting last user’s location //Manifest.permission.ACCESS_FINE_LOCATION private val client = LocationServices.getFusedLocationProviderClient( activity ) client.lastLocation.addOnSuccessListener { location -> . .. }
7. Getting updates on user’s location private val locationCallback = object : LocationCallback() { override fun onLocationResult(r: LocationResult) { // calculate here } }
8. Getting updates on user’s location val locationRequest = LocationRequest .create().apply { priority = PRIORITY_HIGH_ACCURACY interval = 5000 }
9. Getting updates on user’s location client.requestLocationUpdates( locationRequest, locationCallback, Looper.getMainLooper() )
10. Compute distances SphericalUtil .computeDistanceBetween( lastLatLng, oldLatLng )
11. class StepCounter( private val activity: AppCompatActivity ) : SensorEventListener Every step counts
12. Every step counts private val sensorManager : SensorManager = activity.getSystemService(SENSOR_SERVICE) private val stepCounterSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER) private var initialSteps = -1
13. Every step counts fun setupStepCounter() { if (stepCounterSensor != null) { sensorManager.registerListener(this, stepCounterSensor, SENSOR_DELAY_FASTEST) } } fun unloadStepCounter() { if (stepCounterSensor != null) { sensorManager.unregisterListener(this) } }
14. 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
15. SLEEP EXERCISE RECORD
16. SLEEP SLEEP RECOGNITION API
17. Sleep classify event Sleep segment event
18. Sleep segment event •Start timestamp •End timestamp •Duration •Status •Successful •Not detected •Missing data
19. Sleep classify event •Confidence •Light level •Motion level •Timestamp
20. M T W T F S S
21. M T W T F S S
22. Setup Requirements •Android API Level > v29 •Android Build Tools > v21 •Google Play Services Dependency •com.google.android.gms:play-services-location:21.0.0
23. Receiver Android Manifest <receiver android:name=".receiver.SleepReceiver" android:enabled="true" android:exported="true" />
24. Receiver Android Manifest <receiver android:name=".receiver.SleepReceiver" android:enabled="true" android:exported="true" /> SleepReceiver : BroadcastReceiver() override fun onReceive(context: Context, intent: Intent) { if (SleepSegmentEvent.hasEvents(intent)) { .. . } else if (SleepClassifyEvent.hasEvents(intent)) { .. . } }
25. Permissions Android Manifest <uses-permission android:name=“android.permission.ACTIVITY_RECOGNITION" />
26. Permissions Android Manifest <uses-permission android:name=“android.permission.ACTIVITY_RECOGNITION" / > MainActivity ContextCompat.checkSelfPermission( context, permission.ACTIVITY_RECOGNITION )_
27. Permissions Android Manifest <uses-permission android:name=“android.permission.ACTIVITY_RECOGNITION" / > MainActivity ContextCompat.checkSelfPermission(context,permission.ACTIVITY_RECOGNITION)_ val requestPermissionLauncher: ActivityResultLauncher<String> = registerForActivityResult(ActivityResultContracts.RequestPermission()) { isGranted -> if (!isGranted) { … } else { // ready } } requestPermissionLauncher.launch(permission.ACTIVITY_RECOGNITION)
28. Permissions Android Manifest <uses-permission android:name=“android.permission.ACTIVITY_RECOGNITION" / > MainActivity ContextCompat.checkSelfPermission(context,permission.ACTIVITY_RECOGNITION)_ val requestPermissionLauncher: ActivityResultLauncher<String> = registerForActivityResult(ActivityResultContracts.RequestPermission()) { isGranted -> if (!isGranted) { requestActivityRecognitionPermission() } else { // ready } } requestPermissionLauncher.launch(permission.ACTIVITY_RECOGNITION) private fun requestActivityRecognitionPermission() { val intent = Intent().apply { action = Settings.ACTION_APPLICATION_DETAILS_SETTINGS data = Uri.fromParts("package", BuildConfig.APPLICATION_ID, null) flags = Intent.FLAG_ACTIVITY_NEW_TASK } startActivity(intent) }
29. Subscribe to sleep updates MainActivity ActivityRecognition.getClient(context) .requestSleepSegmentUpdates( pendingIntent, SleepSegmentRequest.getDefaultSleepSegmentRequest() )
30. Confidence Motion Light Segments
31. SLEEP EXERCISE RECORD
32. GOOGLE FIT API RECORD
33. Choose options val fitnessOptions = FitnessOptions.builder() .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ) .addDataType(DataType.AGGREGATE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_READ) .build()
34. Request permissions val account = GoogleSignIn.getAccountForExtension( activity, fitnessOptions) if (!GoogleSignIn.hasPermissions(account, fitnessOptions)) { GoogleSignIn.requestPermissions( activity, PERMISSIONS_REQUEST_CODE, account, fitnessOptions) } else { recordToGoogleFit() }
35. Choose options override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) when (resultCode) { Activity.RESULT_OK - > when (requestCode) { PERMISSIONS_REQUEST_CODE -> recordToGoogleFit() else -> { . .. } } else - > { ... } } }
36. Create a session val session = Session.Builder() .setName("Today's Run") .setIdentifier("Unique_Identifier_Here") .setDescription("Long run around home") .setActivity(FitnessActivities.RUNNING) .setStartTime(startTime, TimeUnit.MILLISECONDS) .setEndTime(endTime, TimeUnit.MILLISECONDS) .build()
37. Create a request val insertRequest = SessionInsertRequest.Builder() .setSession(session) .build()
38. Insert request Fitness.getSessionsClient(this, GoogleSignIn.getAccountForExtension(this, fitnessOptions) ) .insertSession(insertRequest) .addOnSuccessListener { ... } .addOnFailureListener { e -> ... }
