How to check if Location Services are enabled in Android App using Kotlin?
This example demonstrates how to check if Location Services are enabled in Android App 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:layout_margin="16dp" tools:context=".MainActivity"> <TextView 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" /> <Button android:id="@+id/button" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" android:text="Check Location Service" /> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/button" android:layout_centerHorizontal="true" android:layout_marginTop="30dp" android:textColor="@android:color/holo_orange_dark" android:textSize="24sp" android:textStyle="bold" /> </RelativeLayout>
Step 3 − Add the following code to src/MainActivity.kt
import android.content.Context
import android.location.LocationManager
import android.os.Bundle
import android.widget.Button
import android.widget.TextView
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
var gpsStatus: Boolean = false
private lateinit var textView: TextView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
textView = findViewById(R.id.textView)
val button: Button = findViewById(R.id.button)
button.setOnClickListener {
locationEnabled()
if (gpsStatus) {
textView.text = "Location Services Is Enabled"
}
else {
textView.text = "Location Services Is Disabled"
}
}
}
private fun locationEnabled() {
val locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
gpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
}
}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_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_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.
