How to get the current location latitude and longitude in android

In my application, I get the current location's latitude and longitude when application is open, but not when the application is closed.

I am using Service class to get the current location latitude and longitude in my application.

Please tell me how to get the current location latitude and longitude even when application is closed

How can I get my current location in Android?

There are two ways to get the current location of any Android device: Android's Location Manager API. Fused Location Provider: Google Play Services Location APIs.

What is my current location latitude and longitude?

On your computer, open Google Maps. Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top.

How do I find latitude and longitude on Google Maps?

Open 'Google Maps': Open maps.google.com in your browser. Click on the search bar: Now click on the search bar at the top left corner. Enter the latitude and coordinates: Now enter the latitude and longitude in Google maps.

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 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);
        }

            // Ask user to enable GPS/network in settings
            gpsTracker.showSettingsAlert();

Note

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

IMPORTANT:

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;

Use Location Listener Method

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