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

@Override

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();
}

Note
If the method / answer doesn't work. You need to use the official Google Provider:
FusedLocationProviderApi.
Article: Getting the Last Known Location
Android :How to get Current Location in Longitude and latitude?
onLocationChanged
gets called every time when your location updates , so keep & update a global value and take that value on your Button
click to do what you want
private LatLng latLng;
@Override
public void onLocationChanged(Location location) {
if(location!=null){
latLng = new LatLng(location.getLatitude(), location.getLongitude()); }
}
or based on time or distance you can get the location as well use android.location.LocationListener()
see Edit for that,
If you want to manually call onLocationChanged
after a time period even the location is not changed use below
LocationRequest mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(30000); //5 seconds
mLocationRequest.setFastestInterval(30000); //3 seconds
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
//mLocationRequest.setSmallestDisplacement(0.1F); //1/10 meter
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
Edit : This is the location listener you can use this separately without the above if you want
private LocationManager locationManager;
private android.location.LocationListener myLocationListener;
public void checkLocation() {
String serviceString = Context.LOCATION_SERVICE;
locationManager = (LocationManager) getSystemService(serviceString);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
myLocationListener = new android.location.LocationListener() {
public void onLocationChanged(Location locationListener) {
if (isGPSEnabled(YourActivityName.this)) {
if (locationListener != null) {
if (ActivityCompat.checkSelfPermission(YourActivityName.this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(YourActivityName.this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
if (locationManager != null) {
location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
} else if (isInternetConnected(YourActivityName.this)) {
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
public void onProviderDisabled(String provider) {
}
public void onProviderEnabled(String provider) {
}
public void onStatusChanged(String provider, int status, Bundle extras) {
}
};
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, myLocationListener);
}
isInternetConnected method
public static boolean isInternetConnected(Context ctx) {
ConnectivityManager connectivityMgr = (ConnectivityManager) ctx
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo wifi = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo mobile = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
// Check if wifi or mobile network is available or not. If any of them is
// available or connected then it will return true, otherwise false;
if (wifi != null) {
if (wifi.isConnected()) {
return true;
}
}
if (mobile != null) {
if (mobile.isConnected()) {
return true;
}
}
return false;
}
isGpsEnabled method
public boolean isGPSEnabled(Context mContext) {
LocationManager locationManager = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);
return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
Note : Now do not get confuse. There are 3 ways mentioned here.
1.use onLocationChanged
automatically
use
onLocationChanged
manuallyuse
android.location.LocationListener()
added the full implementation (this will not help you to learn but to get a data. Go through these lines and understand them by searching what happen actually )
Android - How to get current location (latitude and longitude)?
You have a mistake in your manifest file. Correct one is:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
How to find my current location (latitude + longitude) in every 5 second in Android?
You can use this post to achieve what you are looking for. Look at the setInterval(5000) will do that
