How to enable or disable the GPS programmatically on Kotlin?

This example demonstrates how to enable or disable the GPS programmatically on 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 &minsu; Add the following code to res/layout/activity_main.xml.

Example

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_marginTop="50dp"
      android:padding="8dp"
      android:text="Tutorials Point"
      android:textColor="@android:color/holo_green_dark"
      android:textSize="48sp"
      android:textStyle="bold" />
   <Button
      android:id="@+id/button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerInParent="true"
      android:layout_marginTop="70dp"
      android:onClick="gpsStatus"
      android:text="Click Here to Enable Disable GPS" />
   <TextView
      android:id="@+id/textView"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_below="@+id/button"
      android:layout_centerInParent="true"
      android:textColor="@android:color/holo_green_dark"
      android:textSize="24sp"
      android:textStyle="bold" />
</RelativeLayout>

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

import android.content.Context
import android.content.Intent
import android.location.LocationManager
import android.os.Bundle
import android.provider.Settings
import android.view.View
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
   private lateinit var context: Context
   var intent1: Intent? = null
   lateinit var textView: TextView
   private lateinit var locationManager: LocationManager
   var gpsStatus = false
   override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)
      textView = findViewById(R.id.textView)
      title = "KotlinApp"
      context = applicationContext
      checkGpsStatus()
   }
   private fun checkGpsStatus() {
      locationManager = context.getSystemService(Context.LOCATION_SERVICE) as LocationManager
      gpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
      if (gpsStatus) {
         textView.text = "GPS Is Enabled"
      } else {
         textView.text = "GPS Is Disabled"
      }
   }
   fun gpsStatus(view: View) {
      intent1 = Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
      startActivity(intent1);
   }
}

Step 4 − Add the following code to androidManifest.xml

Example

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.myapplication">
   <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
