How to get the current GPS location programmatically on Android using Kotlin?
This example demonstrates how to get the current GPS location programmatically on Android using 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="4dp" tools:context=".MainActivity"> <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_marginTop="70dp" android:background="#008080" android:padding="5dp" android:text="TutorialsPoint" android:textColor="#fff" android:textSize="24sp" android:textStyle="bold" /> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="Current GPS Location" android:textColor="@color/colorPrimary" android:textSize="24sp" android:textStyle="bold" /> <Button android:id="@+id/getLocation" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/text" android:layout_centerInParent="true" android:layout_marginTop="40dp" android:text="Get location" /> </RelativeLayout>
Step 3 − Add the following code to src/MainActivity.kt
import android.Manifest
import android.content.Context
import android.content.pm.PackageManager
import android.location.Location
import android.location.LocationListener
import android.location.LocationManager
import android.os.Bundle
import android.widget.Button
import android.widget.TextView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.ActivityCompat
import androidx.core.content.ContextCompat
class MainActivity : AppCompatActivity(), LocationListener {
private lateinit var locationManager: LocationManager
private lateinit var tvGpsLocation: TextView
private val locationPermissionCode = 2
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
val button: Button = findViewById(R.id.getLocation)
button.setOnClickListener {
getLocation()
}
}
private fun getLocation() {
locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
if ((ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)) {
ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), locationPermissionCode)
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 5f, this)
}
override fun onLocationChanged(location: Location) {
tvGpsLocation = findViewById(R.id.textView)
tvGpsLocation.text = "Latitude: " + location.latitude + " , Longitude: " + location.longitude
}
override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
if (requestCode == locationPermissionCode) {
if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show()
}
else {
Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show()
}
}
}
}
Step 4 − 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="com.example.q11"> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <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.
