User · Answer

I have got very accurate location using FusedLocationProviderClient
(Google Play services required)

Permissions Required

android.permission.ACCESS_FINE_LOCATION

android.permission.ACCESS_COARSE_LOCATION

Dependency

'com.google.android.gms:play-services-location:15.0.0'

Kotlin Code

val client = FusedLocationProviderClient(this)
val location = client.lastLocation
location.addOnCompleteListener {
    // this is a lambda expression and we get an 'it' iterator to access the 'result'
    // it.result.latitude gives the latitude
    // it.result.longitude gives the longitude 
    val geocoder = Geocoder(applicationContext, Locale.getDefault())
    val address = geocoder.getFromLocation(it.result.latitude, it.result.longitude, 1)
    if (address != null && address.size > 0) {
        // Get the current city
        city = address[0].locality
    }
}
location.addOnFailureListener {
    // Some error in getting the location, let's log it
    Log.d("xtraces", it.message)
}

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 i e  LocationManagerInterface and SmartLocationManager  LocationActivity is implementing the interface and using SmartLocationManager to fetch location

Since I didn t like some of the code in the other answers  here s my simple solution   This solution is meant to be usable in an Activity or Service to track the location   It makes sure that it never returns data that s too stale unless you explicitly request stale data   It can be run in either a callback mode to get updates as we receive them  or in poll mode to poll for the most recent info     Generic LocationTracker interface   Allows us to have multiple types of location trackers and plug the appropriate one in easily   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-  this class will track the location for either GPS or NETWORK   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   -

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  lt  Build VERSION CODES KITKAT                        String provider   Settings Secure                      getString getContentResolver    Settings Secure LOCATION PROVIDERS ALLOWED               if  provider    null  amp  amp   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

As of the second half of 2020  there is a much easier way to do this  Excluding requesting permissions  which I will include at the bottom for devs newer to this   below is the code  Just remember  you need to include at least this version of the library in your dependencies  in the app s build gradle   implementation  com google android gms play-services-location 17 1 0       and of course the fine permission in your manifest   lt uses-permission android name  quot android permission ACCESS FINE LOCATION quot    gt   Kotlin  first the setup   private val fusedLocationClient  FusedLocationProviderClient by lazy       LocationServices getFusedLocationProviderClient applicationContext     private var cancellationTokenSource   CancellationTokenSource    Then the main code  for FINE LOCATION   private fun requestCurrentLocation            Check Fine permission     if  ActivityCompat checkSelfPermission              this              Manifest permission ACCESS FINE LOCATION             PackageManager PERMISSION GRANTED                Main code         val currentLocationTask  Task lt Location gt    fusedLocationClient getCurrentLocation              PRIORITY HIGH ACCURACY              cancellationTokenSource token                    currentLocationTask addOnCompleteListener   task  Task lt Location gt  -

You need to use latest newest      GoogleApiClient Api   Basically what you need to do is   private GoogleApiClient mGoogleApiClient  mGoogleApiClient   new GoogleApiClient Builder this                   addApi LocationServices API                   addConnectionCallbacks this                   addOnConnectionFailedListener this                   build      Then    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                        for the most accurate and reliable location  See my post here   https   stackoverflow com a 33599228 2644905  Do not use LocationListener which is not accurate and has delayed response  To be honest this is easier to implement  Also read documentation  https   developers google com android reference com google android gms common api GoogleApiClient

Since September 23  2020 play-services-location version 17 1 0 includes FusedLocationProviderClient getCurrentLocation   method which is the recommended and straightforward way to get the current location   Returns a single current location fix on the device  Unlike getLastLocation   that returns a cached location  this method could cause active location computation on the device  A single fresh location will be returned if the device location can be determined within reasonable time  tens of seconds   otherwise null will be returned   For a detailed example take a look at codingjeremy s answer and an official Android location sample on GitHub - Current Location  Kotlin

Now that Google Play locations services are here  I recommend that developers start using the new fused location provider  You will find it easier to use and more accurate  Please watch the Google I O video Beyond the Blue Dot  New Features in Android Location by the two guys who created the new Google Play location services API   I ve been working with location APIs on a number of mobile platforms  and I think what these two guys have done is really revolutionary  It s gotten rid of a huge amount of the complexities of using the various providers  Stack Overflow is littered with questions about which provider to use  whether to use last known location  how to set other properties on the LocationManager  etc  This new API that they have built removes most of those uncertainties and makes the location services a pleasure to use   I ve written an Android app that periodically gets the location using Google Play location services and sends the location to a web server where it is stored in a database and can be viewed on Google Maps  I ve written both the client software  for Android  iOS  Windows Phone and Java ME  and the server software  for ASP NET and SQL nbsp Server or PHP and MySQL   The software is written in the native language on each platform and works properly in the background on each  Lastly  the software has the MIT License  You can find the Android client here   https   github com nickfox GpsTracker tree master phoneClients android

I have created a small application with step by step description to get current location s GPS coordinates   Complete example source code is in Get Current Location coordinates   City name - in Android     See how it works    All we need to do is add this permission in the manifest file    lt uses-permission android name  android permission ACCESS FINE LOCATION    gt   And create a LocationManager instance like this   LocationManager locationManager    LocationManager  getSystemService Context LOCATION SERVICE    Check if GPS is enabled or not  And then implement LocationListener and get coordinates   LocationListener locationListener   new MyLocationListener    locationManager requestLocationUpdates  LocationManager GPS PROVIDER  5000  10  locationListener    Here is the sample code to do so       ---------- 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 lt Address gt  addresses          try               addresses   gcd getFromLocation loc getLatitude                        loc getLongitude    1               if  addresses size    gt  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

Getting location updates requires lots of bolierplate code in Android  You need to take care of   Google Play services availablity Check   Update Google play Service if it is old or not available 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     or  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

I will recommend using Smart Location Library Very simple to use and it wraps the location logic nicely   For starting the location service   SmartLocation with context  location        start new OnLocationUpdatedListener               If you just want to get a single location  not periodic  you can just use the oneFix modifier  Example   SmartLocation with context  location        oneFix        start new OnLocationUpdatedListener
