How to get a complete address from latitude and longitude on Android Kotlin?

This example demonstrates how to get a complete address from latitude and longitude on Android Kotlin?

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:padding="16sp"    tools:context=".MainActivity">    <TextView       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerHorizontal="true"       android:layout_marginTop="50dp"       android:text="Tutorials Point"       android:textAlignment="center"       android:textColor="@android:color/holo_green_dark"       android:textSize="32sp"       android:textStyle="bold" />    <Button       android:id="@+id/btnShowAddress"       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:layout_centerInParent="true"       android:text="Show Address" />    <TextView       android:id="@+id/tvAddress"       android:layout_width="fill_parent"       android:layout_height="wrap_content"       android:layout_below="@id/btnShowAddress"       android:layout_centerInParent="true"       android:textColor="@android:color/background_dark"       android:textSize="12sp"       android:textStyle="bold" /> </RelativeLayout>

Step 3 − Add the following code to src/MainActivity.kt

import android.content.Intent import android.content.pm.PackageManager import android.location.Location import android.location.LocationManager import android.os.Bundle import android.os.Handler import android.os.Message import android.provider.Settings import android.widget.Button import android.widget.TextView import android.widget.Toast import androidx.appcompat.app.AlertDialog import androidx.appcompat.app.AppCompatActivity import androidx.core.app.ActivityCompat import androidx.core.content.ContextCompat class MainActivity : AppCompatActivity() {    lateinit var btnShowAddress: Button    lateinit var tvAddress: TextView    lateinit var location: Location    lateinit var appLocationService: AppLocationService    override fun onCreate(savedInstanceState: Bundle?) {       super.onCreate(savedInstanceState)       setContentView(R.layout.activity_main)       title = "KotlinApp"       tvAddress = findViewById(R.id.tvAddress)       appLocationService = AppLocationService(this)       btnShowAddress = findViewById(R.id.btnShowAddress)       if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {          if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) {             ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), 1);          } else {             ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), 1);          }       }       btnShowAddress.setOnClickListener {          location = appLocationService.getLocation(LocationManager.GPS_PROVIDER)!!          val latitude = 13.1000727          val longitude = 80.2126274          val locationAddress = LocationAddress()          locationAddress.getAddressFromLocation(             latitude, longitude, applicationContext, GeoCodeHandler()          )          showSettingsAlert()       }    }    private fun showSettingsAlert() {       val alertDialog = AlertDialog.Builder(this)       alertDialog.setTitle("SETTINGS")       alertDialog.setMessage("Enable Location Provider! Go to settings menu?")       alertDialog.setPositiveButton("Settings") { _, _ ->          val intent = Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)          this@MainActivity.startActivity(intent)       }       alertDialog.setNegativeButton("Cancel") { dialog, _ -> dialog.cancel() }       alertDialog.show()    }    internal inner class GeoCodeHandler : Handler() {       override fun handleMessage(message: Message) {          val locationAddress: String          locationAddress = when (message.what) {             1 -> {                val bundle = message.data                bundle.getString("address")             }             else -> null.toString()          }          tvAddress.text = locationAddress       }    }    override fun onRequestPermissionsResult(       requestCode: Int,       permissions: Array<out String>,       grantResults: IntArray    ) {       when (requestCode) {          1 -> {             if (grantResults.isNotEmpty() && grantResults[0] ===             PackageManager.PERMISSION_GRANTED) {                if ((ContextCompat.checkSelfPermission(                   this@MainActivity,                   Manifest.permission.ACCESS_FINE_LOCATION                ) === PackageManager.PERMISSION_GRANTED)                ) {                   Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show()                }             } else {                Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show()             }             return          }       }    } }

Step 4 − Create a kotlin class and add the following code in AppLocationService.kt

Example

import android.annotation.SuppressLint import android.app.Service import android.content.Context import android.content.Intent import android.location.Location import android.location.LocationListener import android.location.LocationManager import android.os.Bundle import android.os.IBinder open class AppLocationService(context: Context) : Service(), LocationListener {    private var locationManager: LocationManager? =    context.getSystemService(Context.LOCATION_SERVICE) as LocationManager    private lateinit var location: Location    @SuppressLint("MissingPermission")    fun getLocation(provider: String?): Location? {       if (locationManager!!.isProviderEnabled(provider)) {          locationManager!!.requestLocationUpdates(          provider,          MIN_TIME_FOR_UPDATE,          MIN_DISTANCE_FOR_UPDATE.toFloat(), this          )          if (locationManager != null) {             location = locationManager!!.getLastKnownLocation(provider)             return location          }       }       return null    }    override fun onLocationChanged(location: Location) {}    override fun onProviderDisabled(provider: String) {}    override fun onProviderEnabled(provider: String) {}    override fun onStatusChanged(    provider: String,    status: Int,    extras: Bundle    ) {    }    override fun onBind(arg0: Intent): IBinder? {       return null    }    companion object {       private const val MIN_DISTANCE_FOR_UPDATE: Long = 10       private const val MIN_TIME_FOR_UPDATE = 1000 * 60 * 2.toLong()    } }

Step 5 − Create a kotlin class and add the following code in LocationAddress.kt

Example

import android.content.Context import android.location.Geocoder import android.os.Bundle import android.os.Handler import android.os.Message import android.util.Log import java.io.IOException import java.util.* class LocationAddress {    private val tag = "LocationAddress"    fun getAddressFromLocation(    latitude: Double,    longitude: Double, context: Context, handler: Handler    ) {       val thread = object : Thread() {          override fun run() {             val geoCoder = Geocoder(             context,             Locale.getDefault()             )             var result: String = null.toString()             try {                val addressList = geoCoder.getFromLocation(                latitude, longitude, 1                )                if ((addressList != null && addressList.size > 0)) {                   val address = addressList.get(0)                   val sb = StringBuilder()                   for (i in 0 until address.maxAddressLineIndex) {                      sb.append(address.getAddressLine(i)).append("
")                   }                   sb.append(address.locality).append("
")                   sb.append(address.postalCode).append("
")                   sb.append(address.countryName)                   result = sb.toString()                }             } catch (e: IOException) {                Log.e(tag, "Unable connect to GeoCoder", e)             } finally {                val message = Message.obtain()                message.target = handler                message.what = 1                val bundle = Bundle()                result = ("Latitude: " + latitude + " Longitude: " + longitude +                "

Address:
" + result)                bundle.putString("address", result)                message.data = bundle                message.sendToTarget()             }          }       }       thread.start()    } }

Step 6 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.q11"> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>    <application       android:allowBackup="true"       android:icon="@mipmap/ic_launcher"       android:label="@string/app_name"       android:roundIcon="@mipmap/ic_launcher_round"       android:supportsRtl="true"       android:theme="@style/AppTheme">       <activity android:name=".MainActivity">          <intent-filter>             <action android:name="android.intent.action.MAIN" />             <category android:name="android.intent.category.LAUNCHER" />          </intent-filter>       </activity>    </application> </manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
