¿Cómo puedo obtener la ubicación GPS actual mediante programación en Android?

He creado una pequeña aplicación con la descripción paso a paso para obtener las coordenadas GPS de la ubicación actual.

El código fuente completo del ejemplo está en Obtener coordenadas de Ubicación actual, Nombre de la ciudad – en Android .

Vea cómo funciona:

• Todo lo que necesitamos hacer es agregar este permiso en el archivo de manifiesto:

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

• Y cree una instancia LocationManager como esta:

   LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

• Compruebe si el GPS está activado o no.

• Y luego implementar LocationListener y obtener las coordenadas:

   LocationListener locationListener = new MyLocationListener(); locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 5000, 10, locationListener); 

• Aquí está el código de ejemplo para hacerlo

 /*---------- Listener class to get coordinates ------------- */ private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { editLocation.setText(""); pb.setVisibility(View.INVISIBLE); Toast.makeText( getBaseContext(), "Location changed: Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); String longitude = "Longitude: " + loc.getLongitude(); Log.v(TAG, longitude); String latitude = "Latitude: " + loc.getLatitude(); Log.v(TAG, latitude); /*------- To get city name from coordinates -------- */ String cityName = null; Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault()); List<Address> addresses; try { addresses = gcd.getFromLocation(loc.getLatitude(), loc.getLongitude(), 1); if (addresses.size() > 0) { System.out.println(addresses.get(0).getLocality()); cityName = addresses.get(0).getLocality(); } } catch (IOException e) { e.printStackTrace(); } String s = longitude + "\n" + latitude + "\n\nMy Current City is: " + cityName; editLocation.setText(s); } @Override public void onProviderDisabled(String provider) {} @Override public void onProviderEnabled(String provider) {} @Override public void onStatusChanged(String provider, int status, Bundle extras) {} } 

Aquí hay información adicional para otras respuestas.

Ya que Android tiene

 GPS_PROVIDER and NETWORK_PROVIDER 

Puede registrarse en ambos y comenzar a buscar eventos de onLocationChanged(Location location) de dos al mismo tiempo. Hasta aquí todo bien. Ahora la pregunta necesitamos dos resultados o debemos tomar el mejor. Como sé que los resultados GPS_PROVIDER tienen mejor precisión que NETWORK_PROVIDER .

Vamos a definir el campo Location :

 private Location currentBestLocation = null; 

Antes de empezar a escuchar el cambio de ubicación , implementaremos el siguiente método. Este método devuelve la última ubicación conocida, entre el GPS y la red. Para este método nuevo es mejor.

 /** * @return the last know best location */ private Location getLastBestLocation() { Location locationGPS = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); Location locationNet = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); long GPSLocationTime = 0; if (null != locationGPS) { GPSLocationTime = locationGPS.getTime(); } long NetLocationTime = 0; if (null != locationNet) { NetLocationTime = locationNet.getTime(); } if ( 0 < GPSLocationTime - NetLocationTime ) { return locationGPS; } else { return locationNet; } } 

Cada vez que recuperamos una nueva ubicación, la compararemos con nuestro resultado anterior.

 ... static final int TWO_MINUTES = 1000 * 60 * 2; ... 

Añado un nuevo método a onLocationChanged :

 @override public void onLocationChanged(Location location) { makeUseOfNewLocation(location); if(currentBestLocation == null){ currentBestLocation = location; } .... } /** * This method modify the last know good location according to the arguments. * * @param location The possible new location. */ void makeUseOfNewLocation(Location location) { if ( isBetterLocation(location, currentBestLocation) ) { currentBestLocation = location; } } .... /** Determines whether one location reading is better than the current location fix * @param location The new location that you want to evaluate * @param currentBestLocation The current location fix, to which you want to compare the new one. */ protected boolean isBetterLocation(Location location, Location currentBestLocation) { if (currentBestLocation == null) { // A new location is always better than no location return true; } // Check whether the new location fix is newer or older long timeDelta = location.getTime() - currentBestLocation.getTime(); boolean isSignificantlyNewer = timeDelta > TWO_MINUTES; boolean isSignificantlyOlder = timeDelta < -TWO_MINUTES; boolean isNewer = timeDelta > 0; // If it's been more than two minutes since the current location, use the new location, // because the user has likely moved. if (isSignificantlyNewer) { return true; // If the new location is more than two minutes older, it must be worse. } else if (isSignificantlyOlder) { return false; } // Check whether the new location fix is more or less accurate int accuracyDelta = (int) (location.getAccuracy() - currentBestLocation.getAccuracy()); boolean isLessAccurate = accuracyDelta > 0; boolean isMoreAccurate = accuracyDelta < 0; boolean isSignificantlyLessAccurate = accuracyDelta > 200; // Check if the old and new location are from the same provider boolean isFromSameProvider = isSameProvider(location.getProvider(), currentBestLocation.getProvider()); // Determine location quality using a combination of timeliness and accuracy if (isMoreAccurate) { return true; } else if (isNewer && !isLessAccurate) { return true; } else if (isNewer && !isSignificantlyLessAccurate && isFromSameProvider) { return true; } return false; } /** Checks whether two providers are the same */ private boolean isSameProvider(String provider1, String provider2) { if (provider1 == null) { return provider2 == null; } return provider1.equals(provider2); } .... 

Puede encontrar la ubicación mediante GPS_PROVIDER or NETWORK_PROVIDER .

Descripción general de los servicios de ubicación en Android.

Aquí hay un ejemplo que trata de encontrar la ubicación mediante GPS. Si su GPS no está disponible, trate de usar la red para encontrar la ubicación.

GPSTracker.java

  public class GPSTracker extends Service implements LocationListener { private final Context mContext; // Flag for GPS status boolean isGPSEnabled = false; // Flag for network status boolean isNetworkEnabled = false; // Flag for GPS status boolean canGetLocation = false; Location location; // Location double latitude; // Latitude double longitude; // Longitude // The minimum distance to change Updates in meters private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters // The minimum time between updates in milliseconds private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute // Declaring a Location Manager protected LocationManager locationManager; public GPSTracker(Context context) { this.mContext = context; getLocation(); } public Location getLocation() { try { locationManager = (LocationManager) mContext .getSystemService(LOCATION_SERVICE); // Getting GPS status isGPSEnabled = locationManager .isProviderEnabled(LocationManager.GPS_PROVIDER); // Getting network status isNetworkEnabled = locationManager .isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (!isGPSEnabled && !isNetworkEnabled) { // No network provider is enabled } else { this.canGetLocation = true; if (isNetworkEnabled) { locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this); Log.d("Network", "Network"); if (locationManager != null) { location = locationManager .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); if (location != null) { latitude = location.getLatitude(); longitude = location.getLongitude(); } } } // If GPS enabled, get latitude/longitude using GPS Services if (isGPSEnabled) { if (location == null) { locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this); Log.d("GPS Enabled", "GPS Enabled"); if (locationManager != null) { location = locationManager .getLastKnownLocation(LocationManager.GPS_PROVIDER); if (location != null) { latitude = location.getLatitude(); longitude = location.getLongitude(); } } } } } } catch (Exception e) { e.printStackTrace(); } return location; } /** * Stop using GPS listener * Calling this function will stop using GPS in your app. * */ public void stopUsingGPS(){ if(locationManager != null){ locationManager.removeUpdates(GPSTracker.this); } } /** * Function to get latitude * */ public double getLatitude(){ if(location != null){ latitude = location.getLatitude(); } // return latitude return latitude; } /** * Function to get longitude * */ public double getLongitude(){ if(location != null){ longitude = location.getLongitude(); } // return longitude return longitude; } /** * Function to check GPS/Wi-Fi enabled * @return boolean * */ public boolean canGetLocation() { return this.canGetLocation; } /** * Function to show settings alert dialog. * On pressing the Settings button it will launch Settings Options. * */ public void showSettingsAlert(){ AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext); // Setting Dialog Title alertDialog.setTitle("GPS is settings"); // Setting Dialog Message alertDialog.setMessage("GPS is not enabled.

Actividad -AndroidGPSTrackingActivity.java

  public class AndroidGPSTrackingActivity extends Activity { Button btnShowLocation; // GPSTracker class GPSTracker gps; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnShowLocation = (Button) findViewById(R.id.btnShowLocation); // Show location button click event btnShowLocation.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View arg0) { // Create class object gps = new GPSTracker(AndroidGPSTrackingActivity.this); // Check if GPS enabled if(gps.canGetLocation()) { double latitude = gps.getLatitude(); double longitude = gps.getLongitude(); // \n is for new line Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show(); } else { // Can't get location. // GPS or network is not enabled. // Ask user to enable GPS/network in settings. gps.showSettingsAlert(); } } }); } } 

Layout- main.xml

Puesto que no me gustó algo del código en las otras respuestas, aquí está mi solución simple. Esta solución está destinada a ser utilizable en una actividad o servicio para rastrear la ubicación. Se asegura de que nunca devuelve datos demasiado obsoletos a menos que solicite explícitamente datos obsoletos. Se puede ejecutar en un modo de devolución de llamada para obtener actualizaciones a medida que las recibimos o en modo de sondeo para consultar la información más reciente.

Interfaz genérico LocationTracker. Nos permite tener múltiples tipos de rastreadores de ubicación y conectar el adecuado en fácilmente:

 package com.gabesechan.android.reusable.location; import android.location.Location; public interface LocationTracker { public interface LocationUpdateListener{ public void onUpdate(Location oldLoc, long oldTime, Location newLoc, long newTime); } public void start(); public void start(LocationUpdateListener update); public void stop(); public boolean hasLocation(); public boolean hasPossiblyStaleLocation(); public Location getLocation(); public Location getPossiblyStaleLocation(); } 

ProviderLocationTracker- esta clase rastreará la ubicación para el GPS o la RED.

 package com.gabesechan.android.reusable.location; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; public class ProviderLocationTracker implements LocationListener, LocationTracker { // The minimum distance to change Updates in meters private static final long MIN_UPDATE_DISTANCE = 10; // The minimum time between updates in milliseconds private static final long MIN_UPDATE_TIME = 1000 * 60; private LocationManager lm; public enum ProviderType{ NETWORK, GPS }; private String provider; private Location lastLocation; private long lastTime; private boolean isRunning; private LocationUpdateListener listener; public ProviderLocationTracker(Context context, ProviderType type) { lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE); if(type == ProviderType.NETWORK){ provider = LocationManager.NETWORK_PROVIDER; } else{ provider = LocationManager.GPS_PROVIDER; } } public void start(){ if(isRunning){ //Already running, do nothing return; } //The provider is on, so start getting updates. Update current location isRunning = true; lm.requestLocationUpdates(provider, MIN_UPDATE_TIME, MIN_UPDATE_DISTANCE, this); lastLocation = null; lastTime = 0; return; } public void start(LocationUpdateListener update) { start(); listener = update; } public void stop(){ if(isRunning){ lm.removeUpdates(this); isRunning = false; listener = null; } } public boolean hasLocation(){ if(lastLocation == null){ return false; } if(System.currentTimeMillis() - lastTime > 5 * MIN_UPDATE_TIME){ return false; //stale } return true; } public boolean hasPossiblyStaleLocation(){ if(lastLocation != null){ return true; } return lm.getLastKnownLocation(provider)!= null; } public Location getLocation(){ if(lastLocation == null){ return null; } if(System.currentTimeMillis() - lastTime > 5 * MIN_UPDATE_TIME){ return null; //stale } return lastLocation; } public Location getPossiblyStaleLocation(){ if(lastLocation != null){ return lastLocation; } return lm.getLastKnownLocation(provider); } public void onLocationChanged(Location newLoc) { long now = System.currentTimeMillis(); if(listener != null){ listener.onUpdate(lastLocation, lastTime, newLoc, now); } lastLocation = newLoc; lastTime = now; } public void onProviderDisabled(String arg0) { } public void onProviderEnabled(String arg0) { } public void onStatusChanged(String arg0, int arg1, Bundle arg2) { } } 

El es el FallbackLocationTracker, que realizará un seguimiento tanto por GPS como por RED, y utilizará cualquier ubicación que sea más precisa.

 package com.gabesechan.android.reusable.location; import android.content.Context; import android.location.Location; import android.location.LocationManager; public class FallbackLocationTracker implements LocationTracker, LocationTracker.LocationUpdateListener { private boolean isRunning; private ProviderLocationTracker gps; private ProviderLocationTracker net; private LocationUpdateListener listener; Location lastLoc; long lastTime; public FallbackLocationTracker(Context context) { gps = new ProviderLocationTracker(context, ProviderLocationTracker.ProviderType.GPS); net = new ProviderLocationTracker(context, ProviderLocationTracker.ProviderType.NETWORK); } public void start(){ if(isRunning){ //Already running, do nothing return; } //Start both gps.start(this); net.start(this); isRunning = true; } public void start(LocationUpdateListener update) { start(); listener = update; } public void stop(){ if(isRunning){ gps.stop(); net.stop(); isRunning = false; listener = null; } } public boolean hasLocation(){ //If either has a location, use it return gps.hasLocation() || net.hasLocation(); } public boolean hasPossiblyStaleLocation(){ //If either has a location, use it return gps.hasPossiblyStaleLocation() || net.hasPossiblyStaleLocation(); } public Location getLocation(){ Location ret = gps.getLocation(); if(ret == null){ ret = net.getLocation(); } return ret; } public Location getPossiblyStaleLocation(){ Location ret = gps.getPossiblyStaleLocation(); if(ret == null){ ret = net.getPossiblyStaleLocation(); } return ret; } public void onUpdate(Location oldLoc, long oldTime, Location newLoc, long newTime) { boolean update = false; //We should update only if there is no last location, the provider is the same, or the provider is more accurate, or the old location is stale if(lastLoc == null){ update = true; } else if(lastLoc != null && lastLoc.getProvider().equals(newLoc.getProvider())){ update = true; } else if(newLoc.getProvider().equals(LocationManager.GPS_PROVIDER)){ update = true; } else if (newTime - lastTime > 5 * 60 * 1000){ update = true; } if(update){ if(listener != null){ listener.onUpdate(lastLoc, lastTime, newLoc, newTime); } lastLoc = newLoc; lastTime = newTime; } } } 

Dado que ambos implementan la interfaz de LocationTracker, puede cambiar fácilmente su opinión sobre cuál usar. Para ejecutar la clase en modo de sondeo, simplemente llame a start (). Para ejecutarlo en el modo de actualización, llama start (Listener).

También echar un vistazo a mi blog en el código

Ya hay muchas respuestas allí, pero quiero mostrar la última manera de obtener la ubicación mediante la API de Google, por lo que los nuevos programadores pueden utilizar el nuevo método:

He escrito tutorial detallado sobre la ubicación actual en android en mi blog demonuts.com También puede encontrar código fuente completo desarrollado con android studio.

En primer lugar, poner esto en el archivo gradle

  compile 'com.google.android.gms:play-services:9.0.2' 

Luego implementar las interfaces necesarias

 public class MainActivity extends BaseActivitiy implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener 

Declarar instancias

  private GoogleApiClient mGoogleApiClient; private Location mLocation; private LocationManager locationManager; private LocationRequest mLocationRequest; 

Poner esto en onCreate()

  mGoogleApiClient = new GoogleApiClient.Builder(this) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .addApi(LocationServices.API) .build(); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

Por último, anule los métodos necesarios

  @Override public void onConnected(Bundle bundle) { if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } startLocationUpdates(); mLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient); if(mLocation == null){ startLocationUpdates(); } if (mLocation != null) { double latitude = mLocation.getLatitude(); double longitude = mLocation.getLongitude(); } else { // Toast.makeText(this, "Location not Detected", Toast.LENGTH_SHORT).show(); } } protected void startLocationUpdates() { // Create the location request mLocationRequest = LocationRequest.create() .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY) .setInterval(UPDATE_INTERVAL) .setFastestInterval(FASTEST_INTERVAL); // Request location updates if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this); Log.d("reque", "--->>>>"); } @Override public void onConnectionSuspended(int i) { Log.i(TAG, "Connection Suspended"); mGoogleApiClient.connect(); } @Override public void onConnectionFailed(ConnectionResult connectionResult) { Log.i(TAG, "Connection failed. Error: " + connectionResult.getErrorCode()); } @Override public void onStart() { super.onStart(); mGoogleApiClient.connect(); } @Override public void onStop() { super.onStop(); if (mGoogleApiClient.isConnected()) { mGoogleApiClient.disconnect(); } } @Override public void onLocationChanged(Location location) { } 

No olvide iniciar el GPS en su dispositivo antes de ejecutar la aplicación.

Obtener la ubicación de gps por –

 LocationManager locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE); LocationListener locationListener = new LocationListener() { @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onLocationChanged(Location location) { // TODO Auto-generated method stub double latitude = location.getLatitude(); double longitude = location.getLongitude(); double speed = location.getSpeed(); //spedd in meter/minute speed = (speed*3600)/1000; // speed in km/minute Toast.makeText(GraphViews.this, "Current speed:" + location.getSpeed(),Toast.LENGTH_SHORT).show(); } }; locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener); } 

Necesitas usar lo más reciente

GoogleApiClient Api

Básicamente lo que usted necesita hacer es:

 private GoogleApiClient mGoogleApiClient; mGoogleApiClient = new GoogleApiClient.Builder(this) .addApi(LocationServices.API) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .build(); 

Entonces

 @Override public void onConnected(Bundle connectionHint) { mLastLocation = LocationServices.FusedLocationApi.getLastLocation( mGoogleApiClient); if (mLastLocation != null) { mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude())); mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude())); } } 

Para la ubicación más precisa y fiable. Ver mi post aquí:

https://stackoverflow.com/a/33599228/2644905

No utilice LocationListener que no es preciso y tiene respuesta retardada. Para ser honesto, esto es más fácil de implementar. También lee la documentación: https://developers.google.com/android/reference/com/google/android/gms/common/api/GoogleApiClient

 class MyLocation { Timer timer1; LocationManager lm; LocationResult locationResult; boolean gps_enabled = false; boolean network_enabled = false; public boolean getLocation(Context context, LocationResult result) { // I use LocationResult callback class to pass location value from // MyLocation to user code. locationResult = result; if (lm == null) lm = (LocationManager) context .getSystemService(Context.LOCATION_SERVICE); // Exceptions will be thrown if the provider is not permitted. try { gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER); } catch (Exception ex) { } try { network_enabled = lm .isProviderEnabled(LocationManager.NETWORK_PROVIDER); } catch (Exception ex) { } // Don't start listeners if no provider is enabled. if (!gps_enabled && !network_enabled) return false; if (gps_enabled) lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps); if (network_enabled) lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork); timer1 = new Timer(); timer1.schedule(new GetLastLocation(), 5000); return true; } LocationListener locationListenerGps = new LocationListener() { public void onLocationChanged(Location location) { timer1.cancel(); locationResult.gotLocation(location); lm.removeUpdates(this); lm.removeUpdates(locationListenerNetwork); } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; LocationListener locationListenerNetwork = new LocationListener() { public void onLocationChanged(Location location) { timer1.cancel(); locationResult.gotLocation(location); lm.removeUpdates(this); lm.removeUpdates(locationListenerGps); } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; class GetLastLocation extends TimerTask { @Override public void run() { lm.removeUpdates(locationListenerGps); lm.removeUpdates(locationListenerNetwork); Location net_loc = null, gps_loc = null; if (gps_enabled) gps_loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); if (network_enabled) net_loc = lm .getLastKnownLocation(LocationManager.NETWORK_PROVIDER); // If there are both values, use the latest one. if (gps_loc != null && net_loc != null) { if (gps_loc.getTime() > net_loc.getTime()) locationResult.gotLocation(gps_loc); else locationResult.gotLocation(net_loc); return; } if (gps_loc != null) { locationResult.gotLocation(gps_loc); return; } if (net_loc != null) { locationResult.gotLocation(net_loc); return; } locationResult.gotLocation(null); } } public static abstract class LocationResult { public abstract void gotLocation(Location location); } } 

Espero que esto ayude…

Ahora que los servicios de ubicaciones de Google Play están aquí, recomiendo que los desarrolladores comiencen a usar el nuevo proveedor de ubicación fusionada. Lo encontrará más fácil de usar y más preciso. Mire el video de E / S de Google Más allá del punto azul: Nuevas funciones en la ubicación de Android de los dos tipos que crearon la nueva API de servicios de ubicación de Google Play.

He estado trabajando con APIs de ubicación en varias plataformas móviles, y creo que lo que estos dos tipos han hecho es realmente revolucionario. Se ha librado de una gran cantidad de las complejidades de la utilización de los diversos proveedores. El desbordamiento de la pila está lleno de preguntas sobre qué proveedor utilizar, si utilizar la última ubicación conocida, cómo establecer otras propiedades en el LocationManager, etc. Esta nueva API que han construido elimina la mayoría de esas incertidumbres y hace que los servicios de ubicación sean un placer para utilizar.

He escrito una aplicación para Android que periódicamente obtiene la ubicación mediante los servicios de ubicación de Google Play y envía la ubicación a un servidor web donde se almacena en una base de datos y se puede ver en Google Maps . He escrito tanto el software del cliente (para Android, iOS, Windows Phone y Java ME ) y el software de servidor (para ASP.NET y SQL Server o PHP y MySQL ). El software está escrito en el idioma nativo en cada plataforma y funciona correctamente en segundo plano en cada uno. Por último, el software tiene la licencia MIT . Puedes encontrar el cliente Android aquí:

https://github.com/nickfox/GpsTracker/tree/master/phoneClients/android

LocationManager es una clase que proporciona métodos in-build para obtener la última ubicación

PASO 1: Cree un objeto LocationManager como se muestra a continuación

LocationManager locationManager = (LocationManager) context.getSystemService (Context.LOCATION_SERVICE);

PASO 2: Añadir Criterios

 *Criteria is use for setting accuracy* Criteria criteria = new Criteria(); int currentapiVersion = android.os.Build.VERSION.SDK_INT; if (currentapiVersion >= android.os.Build.VERSION_CODES.HONEYCOMB) { criteria.setSpeedAccuracy(Criteria.ACCURACY_HIGH); criteria.setAccuracy(Criteria.ACCURACY_FINE); criteria.setAltitudeRequired(true); criteria.setBearingRequired(true); criteria.setSpeedRequired(true); } 

PASO 3: Obtener proveedor disponible

Hay dos tipos de proveedores de GPS y de red

  String provider = locationManager.getBestProvider(criteria, true); 

PASO 4: Conozca la última ubicación

 Location location = locationManager.getLastKnownLocation(provider); 

PASO 5: Obtener la latitud y la longitud

Si el objeto de ubicación es nulo, entonces no intente llamar por debajo del método s

getLatitude and getLongitude is methods which returns double values

Obtener actualizaciones de la ubicación requiere un montón de código bolierplate en Android, es necesario tener cuidado de

• Disponibilidad de servicios de Google Play Compruebe,
• Actualizar Google Play Service si es viejo o no está disponible
• Dialog Creation of GoogleApiClient and its callbacks connected,disconnected etc.
• Stopping and releasing resources for location updates
• Handling Location permission scenarios
• Checking Location services are On or Off
• Getting lastknown location is not so easy either
• Fallback to last known location if not getting location after certain duration

To ease out all these steps i have created Android-EasyLocation (small android library) which will take care all this stuff and you can focus on business logic.

All you need is extend EasyLocationActivity and this

 requestSingleLocationFix(easyLocationRequest); 

o

 requestLocationUpdates(easyLocationRequest); 

Checkout sample app and steps needed here at https://github.com/akhgupta/Android-EasyLocation

If you are creating new location projects for Android you should use the new Google Play location services. It is much more accurate and much simpler to use.

I have been working on an open source GPS tracker project , GpsTracker, for several years. I recently updated it to handle periodic updates from Android, iOS, Windows Phone and Java ME cell phones. It is fully functional and does what you need and has the MIT License .

The Android project within GpsTracker uses the new Google Play services and there are also two server stacks ( ASP.NET and PHP ) to allow you to track those phones.

Simplest you can find

  package com.javapapers.android.geolocationfinder; import android.os.Bundle; import android.app.Activity; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.widget.TextView; import android.util.Log; public class MainActivity extends Activity implements LocationListener{ protected LocationManager locationManager; protected LocationListener locationListener; protected Context context; TextView txtLat; String lat; String provider; protected String latitude,longitude; protected boolean gps_enabled,network_enabled; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txtLat = (TextView) findViewById(R.id.textview1); locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this); } @Override public void onLocationChanged(Location location) { txtLat = (TextView) findViewById(R.id.textview1); txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude()); } @Override public void onProviderDisabled(String provider) { Log.d("Latitude","disable"); } @Override public void onProviderEnabled(String provider) { Log.d("Latitude","enable"); } @Override public void onStatusChanged(String provider, int status, Bundle extras) { Log.d("Latitude","status"); } } 

I have made a project from which we can get the accurate location using Google Play Services, GPS and Network providers. This project can be found here .

Strategy in finding the best location is that first get the location from google play services if location is found then check weather it is better or not, if location found is null restart google play services and try to fetch the location from Android Location API. Register the location on change listeners and when ever the better location is found the call back returns it to the main activity.

It is very simple to use and implement in code only two classes we need to embed ie LocationManagerInterface and SmartLocationManager , LocationActivity is implementing the interface and using SmartLocationManager to fetch location.

we can use it with activity or a fragment, here i am using it with activity

 import android.location.Location; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.TextView; import android.widget.Toast; import com.example.raza.locationaware.location.LocationManagerInterface; import com.example.raza.locationaware.location.SmartLocationManager; import com.google.android.gms.location.LocationRequest; public class LocationActivity extends AppCompatActivity implements LocationManagerInterface { public static final String TAG = LocationActivity.class.getSimpleName(); SmartLocationManager mLocationManager; TextView mLocalTV, mLocationProviderTV, mlocationTimeTV; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_location); mLocationManager = new SmartLocationManager(getApplicationContext(), this, this, SmartLocationManager.ALL_PROVIDERS, LocationRequest.PRIORITY_HIGH_ACCURACY, 10 * 1000, 1 * 1000, SmartLocationManager.LOCATION_PROVIDER_RESTRICTION_NONE); // init location manager mLocalTV = (TextView) findViewById(R.id.locationDisplayTV); mLocationProviderTV = (TextView) findViewById(R.id.locationProviderTV); mlocationTimeTV = (TextView) findViewById(R.id.locationTimeFetchedTV); } protected void onStart() { super.onStart(); mLocationManager.startLocationFetching(); } protected void onStop() { super.onStop(); mLocationManager.abortLocationFetching(); } @Override protected void onPause() { super.onPause(); mLocationManager.pauseLocationFetching(); } @Override public void locationFetched(Location mLocal, Location oldLocation, String time, String locationProvider) { Toast.makeText(getApplication(), "Lat : " + mLocal.getLatitude() + " Lng : " + mLocal.getLongitude(), Toast.LENGTH_LONG).show(); mLocalTV.setText("Lat : " + mLocal.getLatitude() + " Lng : " + mLocal.getLongitude()); mLocationProviderTV.setText(locationProvider); mlocationTimeTV.setText(time); } } 

Hope it helps, if you can suggest any improvement kindly post it on git . Gracias.

For just location checking you can use following code. You can put it in your onStart() of main activity and display alert dialog if return is false.

 private boolean isLocationAccurate() { if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) { String provider = Settings.Secure .getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED); if (provider != null && !provider.contains("gps")) { return false; } } else { try { int status = Settings.Secure .getInt(this.getContentResolver(), Settings.Secure.LOCATION_MODE); if (status != Settings.Secure.LOCATION_MODE_HIGH_ACCURACY) { return false; } } catch (Settings.SettingNotFoundException e) { Log.e(TAG, e.getMessage()); } } return true; } 

I have published a small library that can make it easy to get location data in Android, it even takes care of Android M runtime permissions.

You might check it out here: https://github.com/julioromano/RxLocation and use it or its source code as examples for your implementation.

Simple Find Write Code in On Location Method

 public void onLocationChanged(Location location) { if (mCurrLocationMarker != null) { mCurrLocationMarker.remove(); } //Place current location marker LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude()); MarkerOptions markerOptions = new MarkerOptions(); markerOptions.position(latLng); markerOptions.title("Current Position"); markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)); mCurrLocationMarker = mMap.addMarker(markerOptions); //move map camera mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); mMap.animateCamera(CameraUpdateFactory.zoomTo(18)); PolylineOptions pOptions = new PolylineOptions() .width(5) .color(Color.GREEN) .geodesic(true); for (int z = 0; z < routePoints.size(); z++) { LatLng point = routePoints.get(z); pOptions.add(point); } line = mMap.addPolyline(pOptions); routePoints.add(latLng); }
