        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 v) {       
                // 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{

                    // \n is for new line
                    Toast.makeText(
                            getApplicationContext(),
                            "Your Location is - \nLat: " + latitude
                                    + "\nLong: " + longitude, Toast.LENGTH_LONG)

                }

            }
        });

But I get Error in below::::

Use This:

 Geocoder geocoder = new Geocoder(this, Locale.getDefault());
 List<Address> addresses = geocoder.getFromLocation(MyLat, MyLong, 1);
 String cityName = addresses.get(0).getAddressLine(0);
 String stateName = addresses.get(0).getAddressLine(1);
 String countryName = addresses.get(0).getAddressLine(2);

For more in detailed google map example you check the links below: http://www.demoadda.com/demo/android/load-googlemap_107

And for the background location updates: http://www.demoadda.com/demo/android/download-android-background-location-update-service-demo_21

On your onClick add this:

Geocoder gcd = new Geocoder(AndroidGPSTrackingActivity.this, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) 
    System.out.println(addresses.get(0).getLocality());
gps = new LocationAddress(getActivity());
if (gps.canGetLocation()) {
  double latitude = gps.getLatitude();
  double longitude = gps.getLongitude();
  Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
  //List<Address> addresses =geocoder.getFromLocation(latitude, longitude, 1);

  try {
    List < Address > addresses = geocoder.getFromLocation(latitude, longitude, 1);
    String address = addresses.get(0).getSubLocality();
    String cityName = addresses.get(0).getLocality();
    String stateName = addresses.get(0).getAdminArea();
    txt_paddress.setText(address);
    txt_city.setText(cityName);
    txt_state.setText(stateName);

  } catch (IOException e) {
    e.printStackTrace();
  }
} else {
  gps.showSettingsAlert();
}

For my country (Vietnam) getLocality will return null and addresses.get(0).getAddressLine(0) will return the district not city

So I will do like this

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);

int maxAddressLine = addresses.get(0).getMaxAddressLineIndex();

String countryName = addresses.get(0).getAddressLine(maxAddressLine);
String stateName = addresses.get(0).getAddressLine(maxAddressLine-1);
String cityName = addresses.get(0).getAddressLine(maxAddressLine-2);

Use Geocoder. Pass the latitude and longitude and get city name and address.

try {

    Geocoder geo = new Geocoder(this.getApplicationContext(), Locale.getDefault());
    List < Address > addresses = geo.getFromLocation(latitude, longitude, 1);
    if (addresses.isEmpty()) {
        addres.setText("Waiting for Location");
    } else {
        if (addresses.size() > 0) {
            addres.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() + ", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
            //Toast.makeText(getApplicationContext(), "Address:- " + addresses.get(0).getFeatureName() + addresses.get(0).getAdminArea() + addresses.get(0).getLocality(), Toast.LENGTH_LONG).show();
        }
    }
} catch (Exception e) {
    e.printStackTrace(); // getFromLocation() may sometimes fail
}

Use this and pass your lat long values to it.

    Geocoder geocoder;
    List<Address> addresses;
    geocoder = new Geocoder(getContext(), Locale.getDefault());

    try {
        addresses = geocoder. getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
        String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
        String city = addresses.get(0).getLocality();
        String state = addresses.get(0).getAdminArea();
        String country = addresses.get(0).getCountryName();else return NULL
    } catch (IOException e) {
        e.printStackTrace();
    }

I only need to show country and city name, so I am using following code Here I am using "en" for always showing country and city name in English language instead of users regional language. Otherwise you can Locale.getDefault() method.

 double latitude = location.getLatitude();
 double longitude = location.getLongitude();

 Locale locale = new Locale("en"); //OR Locale.getDefault()

 Geocoder geocoder = new Geocoder(MainActivity.this, locale);
 List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);

 updatedCity = addresses.get(0).getLocality();

 if (updatedCity == null) {
     updatedCity = addresses.get(0).getAdminArea();
 }

 updatedCountry = addresses.get(0).getCountryName();

none any of answer above solve my case

for case in Indonesia, you can call addresses.get(0).getSubAdminArea() to get city name

Kotlin example:

private fun getCityNameWithLocation(lat: Double, long: Double) {
        val geocoder = Geocoder(requireContext(), Locale.getDefault())
        val addresses: List<Address> = geocoder.getFromLocation(lat, long, 1)
        if(addresses.isNotEmpty()) {
            val cityName: String = addresses[0].getAddressLine(0)
            Timber.d("cityName: $cityName")
        }
    }
