Footstep two − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-viii"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context=".MainActivity"> <TextView    android:layout_marginTop="20dp"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="Get Current Location and City Name"    android:textAlignment="center"    android:layout_centerHorizontal="true"    android:textSize="20sp" /> <TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/textView"    android:layout_centerInParent="true"    android:textSize="16sp"    android:textStyle="bold"/> </RelativeLayout>

Step three − Add the following dependency in Gradle

implementation 'com.google.android.gms:play-services-location:17.0.0'

Step iv − Add the following code to src/MainActivity.java

import androidx.notation.NonNull; import androidx.appcompat.app.AppCompatActivity; import androidx.core.app.ActivityCompat; import androidx.core.content.ContextCompat; import android.Manifest; import android.content.Intent; import android.content.pm.PackageManager; import android.location.Geocoder; import android.location.Location; import android.os.Packet; import android.os.Handler; import android.os.ResultReceiver; import android.util.Log; import android.widget.TextView; import android.widget.Toast; import com.google.android.gms.location.FusedLocationProviderClient; import com.google.android.gms.location.LocationCallback; import com.google.android.gms.location.LocationRequest; import com.google.android.gms.location.LocationResult; import com.google.android.gms.location.LocationServices; public grade MainActivity extends AppCompatActivity {    private FusedLocationProviderClient fusedLocationClient;    private static final int LOCATION_PERMISSION_REQUEST_CODE = 2;    individual LocationAddressResultReceiver addressResultReceiver;    private TextView currentAddTv;    private Location currentLocation;    private LocationCallback locationCallback;    @Override    protected void onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       setContentView(R.layout.activity_main);       addressResultReceiver = new LocationAddressResultReceiver(new Handler());       currentAddTv = findViewById(R.id.textView);       fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);       locationCallback = new LocationCallback() {          @Override          public void onLocationResult(LocationResult locationResult) {             currentLocation = locationResult.getLocations().go(0);             getAddress();          }       };       startLocationUpdates();    }    @SuppressWarnings("MissingPermission")    individual void startLocationUpdates() {       if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) !=       PackageManager.PERMISSION_GRANTED) {          ActivityCompat.requestPermissions(this, new          String[]{Manifest.permission.ACCESS_FINE_LOCATION},          LOCATION_PERMISSION_REQUEST_CODE);       }       else {          LocationRequest locationRequest = new LocationRequest();          locationRequest.setInterval(2000);          locationRequest.setFastestInterval(chiliad);          locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);          fusedLocationClient.requestLocationUpdates(locationRequest, locationCallback, zilch);       }    }    @SuppressWarnings("MissingPermission")    individual void getAddress() {       if (!Geocoder.isPresent()) {          Toast.makeText(MainActivity.this, "Can't find electric current accost, ",          Toast.LENGTH_SHORT).bear witness();          render;       }       Intent intent = new Intent(this, GetAddressIntentService.class);       intent.putExtra("add_receiver", addressResultReceiver);       intent.putExtra("add_location", currentLocation);       startService(intent);    }    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    if (requestCode == LOCATION_PERMISSION_REQUEST_CODE) {       if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {          startLocationUpdates();       }        else {          Toast.makeText(this, "Location permission not granted, " + "restart the app if you want the          feature", Toast.LENGTH_SHORT).show();       }    } } private class LocationAddressResultReceiver extends ResultReceiver {    LocationAddressResultReceiver(Handler handler) {       super(handler);    }    @Override    protected void onReceiveResult(int resultCode, Parcel resultData) {       if (resultCode == 0) {          Log.d("Address", "Location aught retrying");          getAddress();       }       if (resultCode == 1) {          Toast.makeText(MainActivity.this, "Address not found, ", Toast.LENGTH_SHORT).bear witness();       }       String currentAdd = resultData.getString("address_result");          showResults(currentAdd);       }    }    private void showResults(String currentAdd) {       currentAddTv.setText(currentAdd);    }    @Override    protected void onResume() {       super.onResume();       startLocationUpdates();    }    @Override    protected void onPause() {       super.onPause();       fusedLocationClient.removeLocationUpdates(locationCallback);    } }        

Stride v − Create a new java class GetaddressIntentService.java and add the following code

parcel app.com.sample; import android.app.IntentService; import android.content.Intent; import android.location.Address; import android.location.Geocoder; import android.location.Location; import android.os.Parcel; import android.os.ResultReceiver; import android.util.Log; import java.util.List; import java.util.Locale; import java.util.Objects; import androidx.note.Nullable; public class GetAddressIntentService extends IntentService {    private static final Cord IDENTIFIER = "GetAddressIntentService";    private ResultReceiver addressResultReceiver;    public GetAddressIntentService() {       super(IDENTIFIER);    }    @Override    protected void onHandleIntent(@Nullable Intent intent) {       String msg;       addressResultReceiver = Objects.requireNonNull(intent).getParcelableExtra("add_receiver");       if (addressResultReceiver == null) {          Log.east("GetAddressIntentService", "No receiver, non processing the request further");          render;       }       Location location = intent.getParcelableExtra("add_location");       if (location == cipher) {          msg = "No location, can't go further without location";          sendResultsToReceiver(0, msg);       return;    }    Geocoder geocoder = new Geocoder(this, Locale.getDefault());    List<Address> addresses = null;    effort {       addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), ane);    }    catch (Exception ioException) {       Log.eastward("", "Error in getting accost for the location");    }    if (addresses == nada || addresses.size() == 0) {       msg = "No address found for the location";       sendResultsToReceiver(ane, msg);    }    else {       Address accost = addresses.get(0);       String addressDetails = address.getFeatureName() + "\n" + address.getThoroughfare() + "\northward" +       "Locality: " + accost.getLocality() + "\north" + "County: " + address.getSubAdminArea() + "\northward" +       "State: " + address.getAdminArea() + "\n" + "Land: " + address.getCountryName() + "\northward" +       "Postal Lawmaking: " + address.getPostalCode() + "\northward";       sendResultsToReceiver(two, addressDetails);    } } private void sendResultsToReceiver(int resultCode, String bulletin) {    Bundle packet = new Bundle();    parcel.putString("address_result", bulletin);    addressResultReceiver.send(resultCode, package);    } }        

Step half dozen − Add together the following code to androidManifest.xml

<?xml version="ane.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"    packet="app.com.sample">    <awarding       android:allowBackup="true"       android:icon="@mipmap/ic_launcher"       android:label="@cord/app_name"       android:roundIcon="@mipmap/ic_launcher_round"       android:supportsRtl="true"       android:theme="@mode/AppTheme">       <activity android:name=".MainActivity">          <intent-filter>             <action android:name="android.intent.action.MAIN" />             <category android:name="android.intent.category.LAUNCHER" />          </intent-filter>       </activeness>    <service android:name=".GetAddressIntentService" /> </awarding> <uses-permission android:proper name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:proper noun="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> </manifest>

Let's endeavor to run your awarding. I assume you have connected your bodily Android Mobile device with your calculator.
