i am making an app in android using java which show current address on map and give alert whenever gps is off.

public class LocationManagerCheck {

    LocationManager locationManager;
    Boolean locationServiceBoolean = false;
    int providerType = 0;
    static AlertDialog alert;

    public LocationManagerCheck(Context context) {
        locationManager = (LocationManager) context
                .getSystemService(Context.LOCATION_SERVICE);
        boolean gpsIsEnabled = locationManager
                .isProviderEnabled(LocationManager.GPS_PROVIDER);
        boolean networkIsEnabled = locationManager
                .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        if (networkIsEnabled == true && gpsIsEnabled == true) {
            locationServiceBoolean = true;
            providerType = 1;

        } else if (networkIsEnabled != true && gpsIsEnabled == true) {
            locationServiceBoolean = true;
            providerType = 2;

        } else if (networkIsEnabled == true && gpsIsEnabled != true) {
            locationServiceBoolean = true;
            providerType = 1;
        }

    }

    public Boolean isLocationServiceAvailable() {
        return locationServiceBoolean;
    }

    public int getProviderType() {
        return providerType;
    }

    public void createLocationServiceError(final Activity activity) {

        // show alert dialog if Internet is not connected
        AlertDialog.Builder builder = new AlertDialog.Builder(activity);

        builder.setMessage(
                "You need to activate location service to use this feature. Please turn on network or GPS mode in location settings")
                .setTitle("LostyFound")
                .setCancelable(false)
                .setPositiveButton("Settings",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                Intent intent = new Intent(
                                        Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                                activity.startActivity(intent);
                                dialog.dismiss();
                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                dialog.dismiss();
                            }

You probably want to know whether the user turns ON/OFF the GPS. This question may help

For this, u have to use Broadcast receiver

First, you have to register broadcast

  private var receiverRegistered: Boolean = false

     override fun onCreate(savedInstanceState: Bundle?) {
                super.onCreate(savedInstanceState)
                registerBroadcast()
        }

     private fun registerBroadcast() {
            val filter = IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION)
            filter.addAction(Intent.ACTION_PROVIDER_CHANGED)
            this.registerReceiver(broadCastReceiver, filter)
            receiverRegistered = true
        }

private val broadCastReceiver = object : BroadcastReceiver() {
        override fun onReceive(contxt: Context?, intent: Intent?) {
            if (LocationManager.PROVIDERS_CHANGED_ACTION == intent?.action) {
                val locationManager = contxt?.getSystemService(Context.LOCATION_SERVICE) as LocationManager
                val isGpsEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)
                if (!isGpsEnabled) {
                    // call your alert here
                } 
            }
        }
    }

And the most important thing unregister the broadcast receiver

override fun onDestroy() {
        if (receiverRegistered) {
            this.unregisterReceiver(broadCastReceiver)
        }
        super.onDestroy()
    }

Every time user turn off the GPS it will show alert.

you can check from here to register the receiver in java https://stackoverflow.com/a/4805733/11834065 — Shivam Sharma, Oct 14 '19 at 08:58
