Slides usados no TDC Porto Alegre

Transcript

1. Nova API de localização para Android Diminuindo fricção
2. Caique Oliveira Graduado em Ciência da computação - UFS Android developer - Stone Apresentação
3. Trabalhando com localização no Android
4. Implementar GooglePlayServicesClient - ConnectionCallbacks - OnConnectionFailedListener
5. ConnectionCallbacks override fun onConnected(p0: Bundle?){ } override fun onConnectionSuspended(p0: Int){ }
6. OnConnectionFailedListener override fun onConnectionFailed(p0: ConnectionResult) { }
7. Configurar GoogleApiClient fun initGoogleApiClient() { if (mGoogleApiClient != null) { mGoogleApiClient = GoogleApiClient.Builder( this) .addConnectionCallbacks( this) .addOnConnectionFailedListener( this) .addApi(LocationServices. API) .build() } mGoogleApiClient?.connect() }
8. Conectar ao Play Services override fun onStart() { mGoogleApiClient?.connect() super.onStart() }
9. Desconectar de acordo com o ciclo de vida override fun onStop() { mGoogleApiClient?.disconnect() super.onStop() }
10. fun getLocation(): Location { return LocationServices.FusedLocationApi .getLastLocation(mGoogleApiClient) }
11. Meu Deus do Céu
12. Todo app é a mesma coisa
13. “É realmente necessário que eu mesmo controle o GoogleApiClient?”
14. “Eu realmente preciso controlar o ciclo de vida dele?”
15. Android Architecture Components
16. Android Architecture Components - Menor escrita de código - Framework gerencia o ciclo de vida - Traz uma melhor experiência para o desenvolvedor
17. Reduzindo o atrito ao trabalhar com Location
18. implementation ‘com.google.android.gms:play-services-location:11.6.0’
19. LastLocation LocationServices.getFusedLocationProviderClient(this) .lastLocation.addOnSuccessListener({ location -> Log.e("location", location.toString()) })
20. implementa OnFailureListener override fun onFailure(p0: Exception) { val statusCode = (p0 as ApiException).statusCode when (statusCode) { RESOLUTION_REQUIRED -> { //Fix in Settings." } SETTINGS_CHANGE_UNAVAILABLE -> { //Fix in Settings." } } }
21. LastLocation LocationServices.getFusedLocationProviderClient(this) .lastLocation.addOnSuccessListener({ location -> Log.v("location", location.toString()) }).addOnFailureListener(this)
22. Location Updates LocationServices.getFusedLocationProviderClient(this) .requestLocationUpdates( locationRequest = mLocationRequest, locationCallback = mLocationCallback, looper = Looper.myLooper())
23. Location Updates - Callback val mLocationCallback = object : LocationCallback() { override fun onLocationResult(result: LocationResult?) { super.onLocationResult(result) Log.v("location",locationResult?.lastLocation?.toString()) } }
24. Location Updates - Request val mLocationRequest = LocationRequest() .setInterval(UPDATE_INTERVAL_IN_MILLISECONDS) .setFastestInterval(UPDATE_INTERVAL_IN_MILLISECONDS) .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
25. Temos agora o foco para obter de forma simples uma localização ou resolver um problema
