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

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;
import com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener;
import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.maps.GoogleMap;
public class HomeActivity extends AppCompatActivity implements
ConnectionCallbacks,
OnConnectionFailedListener,
LocationListener {
//Define a request code to send to Google Play services
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
private double currentLatitude;
private double currentLongitude;
@Override
protected void onCreate(Bundle savedInstanceState) {
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()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(10 * 1000) // 10 seconds, in milliseconds
.setFastestInterval(1 * 1000); // 1 second, in milliseconds
}
@Override
protected void onResume() {
super.onResume();
//Now lets connect to the API
mGoogleApiClient.connect();
}
@Override
protected void onPause() {
super.onPause();
Log.v(this.getClass().getSimpleName(), "onPause()");
//Disconnect from API onPause()
if (mGoogleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
mGoogleApiClient.disconnect();
}
}
/**
* If connected get lat and long
*
*/
@Override
public void onConnected(Bundle bundle) {
Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (location == null) {
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
} else {
//If everything went fine lets get latitude and longitude
currentLatitude = location.getLatitude();
currentLongitude = location.getLongitude();
Toast.makeText(this, currentLatitude + " WORKS " + currentLongitude + "", Toast.LENGTH_LONG).show();
}
}
@Override
public void onConnectionSuspended(int i) {}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
/*
* Google Play services can resolve some errors it detects.
* If the error has a resolution, try sending an Intent to
* start a Google Play services activity that can resolve
* error.
*/
if (connectionResult.hasResolution()) {
try {
// Start an Activity that tries to resolve the error
connectionResult.startResolutionForResult(this, CONNECTION_FAILURE_RESOLUTION_REQUEST);
/*
* Thrown if Google Play services canceled the original
* PendingIntent
*/
} catch (IntentSender.SendIntentException e) {
// Log the error
e.printStackTrace();
}
} else {
/*
* If no resolution is available, display a dialog to the
* user with the error.
*/
Log.e("Error", "Location services connection failed with code " + connectionResult.getErrorCode());
}
}
/**
* If locationChanges change lat and long
*
*
* @param location
*/
@Override
public void onLocationChanged(Location location) {
currentLatitude = location.getLatitude();
currentLongitude = location.getLongitude();
Toast.makeText(this, currentLatitude + " WORKS " + currentLongitude + "", Toast.LENGTH_LONG).show();
}
}
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();
}
