Problem with the MapsActivity of google maps

Navigation

I'm inserting a geolocation in Android Studio for an app: 

private void miUbiacion() {
        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return;
        }
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        actualizarUbicacion(location);
        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,15000,0,locListener);
    } '

And I do not take the locListener since I have the imported libraries correctly 

import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;

I do not know how to fix it, it does not let me import it or anything just comes out in red, any suggestions?

Good afternoon! To get the location you have to follow three simple steps:

Step 1: Add the following compilation to the build.gradle in the dependencies

  

compile 'com.google.android.gms: play-services-location: 10.2.0'

Step 2: Add the location permission to the manifest.xml

  

*<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>*

Step 3: When you ask for the permissions in your function MyLocation (), you have to remove the return and add the line that asks for the permissions

  

ActivityCompat.requestPermissions (this, new   String [] {Manifest.permission.ACCESS_FINE_LOCATION,}, 1000);           }

So it would look like this: 

*if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {*
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION,}, 10000);
    *}*

You can also add this line so that the button that takes you to your location appears

  

Map.setMyLocationEnabled (true);

You need to add the Google Play Services dependency to use location services 

implementation 'com.google.android.gms:play-services-location:11.4.2'

You have a misunderstanding, locListener is not a class that you import, it is a listener that you have to create, it is the last parameter required by requestLocationUpdates() .

  

requestLocationUpdates (String provider, long minTime, float   minDistance, LocationListener listener) Register for   Location updates using the provider, and a Pending Intent.

What you can do is that your Activity extends from LocationListener , implement the required methods. 

public class MainActivity extends Activity implements LocationListener {

and in this way refer to the Activity: 

locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,15000,0,this);
