How to get the current location latitude and longitude in android

Before couple of months, I created GPSTracker library to help me to get GPS locations. In case you need to view GPSTracker > getLocation

Demo

AndroidManifest.xml

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

Activity

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

    TextView textview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.geo_locations);

        // check if GPS enabled
        GPSTracker gpsTracker = new GPSTracker(this);

        if (gpsTracker.getIsGPSTrackingEnabled())
        {
            String stringLatitude = String.valueOf(gpsTracker.latitude);
            textview = (TextView)findViewById(R.id.fieldLatitude);
            textview.setText(stringLatitude);

            String stringLongitude = String.valueOf(gpsTracker.longitude);
            textview = (TextView)findViewById(R.id.fieldLongitude);
            textview.setText(stringLongitude);

            String country = gpsTracker.getCountryName(this);
            textview = (TextView)findViewById(R.id.fieldCountry);
            textview.setText(country);

            String city = gpsTracker.getLocality(this);
            textview = (TextView)findViewById(R.id.fieldCity);
            textview.setText(city);

            String postalCode = gpsTracker.getPostalCode(this);
            textview = (TextView)findViewById(R.id.fieldPostalCode);
            textview.setText(postalCode);

            String addressLine = gpsTracker.getAddressLine(this);
            textview = (TextView)findViewById(R.id.fieldAddressLine);
            textview.setText(addressLine);
        }
        else
        {
            // can't get location
            // GPS or Network is not enabled
            // Ask user to enable GPS/network in settings
            gpsTracker.showSettingsAlert();
        }
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.varna_lab_geo_locations, menu);
        return true;
    }

Note

If the method / answer doesn't work. You need to use the official Google Provider: FusedLocationProviderApi.

Please notice this solution is from 2015 might be too old and deprecated.


None of the above worked for me so I made a tutorial and wrote it for myself since I lost many hours trying to implement this. Hope this helps someone:

How to use Google Play Services LOCATION API to get current latitude & longitude

1) Add to your AndroidManifest.xml file the ACCESS_COARSE_LOCATION & ACCESS_FINE_LOCATION:

    <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.appname" >

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

        <application...

2) Go to app/build.gradlefile and add the following dependency (make sure to use the latest available version):

    dependencies {
        //IMPORTANT: make sure to use the newest version. 11.0.1 is old AF
        compile 'com.google.android.gms:play-services-location:11.0.1
    }

3) In your activity implement the following:

    import com.google.android.gms.common.ConnectionResult;
    import com.google.android.gms.common.api.GoogleApiClient;
    import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
    import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
    import com.google.android.gms.location.LocationListener;

        private double currentLongitude;


        @Override

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_home);

            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    // The next two lines tell the new client that “this” current class will handle connection stuff
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    //fourth line adds the LocationServices API endpoint from GooglePlayServices
                    .addApi(LocationServices.API)
                    .build();

            // Create the LocationRequest object
            mLocationRequest = LocationRequest.create()

                    .setInterval(10 * 1000)        // 10 seconds, in milliseconds
                    .setFastestInterval(1 * 1000); // 1 second, in milliseconds

        }

If you need more info just go to:

The Beginner’s Guide to Location in Android

Note: This doesn't seem to work in the emulator but works just fine on a device


Use Location Listener Method

@Override
public void onLocationChanged(Location loc) {
Double lat = loc.getLatitude();
Double lng = loc.getLongitude();
}
