No suitable method found for requestLocationUpdates

Question

This is my MainActivity.java:

import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;


public class MainActivity extends Activity {



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        LocationListener locationListener = new GetCurrentLocation();
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
}

And this is my GetCurrentLocation.java:

import android.app.Activity;
import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Toast;

import com.google.android.gms.location.LocationListener;

import java.io.IOException;
import java.util.List;
import java.util.Locale;

public class GetCurrentLocation extends Activity implements LocationListener {
    String longitude;
    String latitude;
    String cityName;

    public void onLocationChanged(Location loc) {
        //editLocation.setText("");
        //pb.setVisibility(View.INVISIBLE);
        Toast.makeText(
                getBaseContext(),
                "Location changed: Lat: " + loc.getLatitude() + " Lng: "
                        + loc.getLongitude(), Toast.LENGTH_SHORT).show();
        longitude = "Longitude: " + loc.getLongitude();
        //Log.v(TAG, longitude);
        latitude = "Latitude: " + loc.getLatitude();
        //Log.v(TAG, latitude);

        /*------- To get city name from coordinates -------- */
        //String cityName = null;
        Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault());
        List<Address> addresses;
        try {
            addresses = gcd.getFromLocation(loc.getLatitude(),
                    loc.getLongitude(), 1);
            if (addresses.size() > 0)
                System.out.println(addresses.get(0).getLocality());
            cityName = addresses.get(0).getLocality();
        }
        catch (IOException e) {
            e.printStackTrace();
        }

        //editLocation.setText(s);
    }

    //@Override
    public void onProviderDisabled(String provider) {}

    //@Override
    public void onProviderEnabled(String provider) {}

    //@Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}


}

The error I got is:

Error:(40, 24) error: no suitable method found for requestLocationUpdates(String,int,int,com.google.android.gms.location.LocationListener)
method LocationManager.requestLocationUpdates(long,float,Criteria,PendingIntent) is not applicable

I am totally blank on which part of the code I should fix and I have tried to google but no relevant solution can be found.

Answer 1

You are using the wrong LocationListener class. You need to replace this:

import com.google.android.gms.location.LocationListener;

with this:

import android.location.LocationListener;

The com.google.android.gms.location stuff is for use with the FusedLocationProviderApi which is part of Google play services.

The standard Android location stuff is in android.location.

Also, you have GetCurrentLocation extends Activity. But it isn't really an Activity. You need to remove the extends Activity clause. This will then cause problems because you are calling getBaseContext() in some methods of that class. To fix this, have the constructor of GetCurrentLocation take a Context parameter and save that in a private member variable. Then use that when you need a Context instead of calling getBaseContext().

In MainActivity, when you create a new GetCurrentLocation, you can do this:

LocationListener locationListener = new GetCurrentLocation(this);

passing this as the Context parameter (Activity extends Context).

Answer 2

The error telling you that there is no overload method requestLocationUpdates that accepts parameters (String,int,int,com.google.android.gms.location.LocationListener)

The closer method is

requestLocationUpdates(String provider, long minTime, float minDistance,
                       LocationListener listener);

So possible solution to fix your error is:

long t = 5000;
float d = 10;
locationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, t, d, locationListener);
