I want to store current Location to database when i click on Button.
The location is stored but it is receiving 0.0 ,0.0 don't know where's the mistake is in my code Here i post my complete code for this please help me out from this.
getting current location
GetCurrentGPSLocation gps = new GetCurrentGPSLocation(getActivity());
// check if GPS enabled
if (gps.canGetLocation()) {
double latitude = gps.getLatitude();
double longitude = gps.getLongitude();
// \n is for new line
lat.setText( ""+latitude);
longi.setText("" +longitude);
latitude12=lat.getText().toString();
longitude12=longi.getText().toString();
Toast.makeText(getActivity(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();
longi.setVisibility(View.INVISIBLE);
lat.setVisibility(View.INVISIBLE);
} else {
// can't get location
// GPS or Network is not enabled
// Ask user to enable GPS/network in settings
gps.showSettingsAlert();
}

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

}
Note : Now do not get confuse. There are 3 ways mentioned here.
1.use onLocationChanged automatically
use onLocationChanged manually
use 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 )
