How to design a location tracking App using GPS in Android Studio - source code?

This video shows the steps to create an App which uses Google Map to give the precise location of your phone. This app can be used to track your current position. In the initial part of the video it shows how to create API Key to have the access of the google Map.

This custom app works offline based on GPS and you do not need internet connection to get your current location.


For 2nd part of this tutorial please refer to the below video: https://youtu.be/FknRti6n_F8

I am pasting the main method code below (for complete class please contact):

public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;

// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));

locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {

try {
latLng = new LatLng(location.getLatitude(), location.getLongitude());

mMap.addMarker(new MarkerOptions().position(latLng).title("My Current Position"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
}
catch (SecurityException e){
e.printStackTrace();
}
}

@Override
public void onStatusChanged(String s, int i, Bundle bundle) {

}

@Override
public void onProviderEnabled(String s) {

}

@Override
public void onProviderDisabled(String s) {

}
};

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

try {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_UPDATE_TIME, MIN_UPDATES_DISTANCE, locationListener);
}
catch (SecurityException e){
e.printStackTrace();
}
}
}
