As per Android documentation you need to pass location provider in the constructor. Refer https://developer.android.com/reference/android/location/Location.html#Location(java.lang.String)

You need to parse the string ("lat/lng: (28.6988812,77.1153696)") that you are getting from you server, extract latitude and longitude and pass those values to your location object using setLatitude() and setLongitude() function.

You can extract latitude and longitude from the location string you got from the server with regex. Like this:

Double latitude = 0., longitude = 0.;

    //your location
    String location = "lat/long: (28.6988812,77.1153696)";
    //pattern
    Pattern pattern = Pattern.compile("lat/long: \\(([0-9.]+),([0-9.]+)\\)$");
    Matcher matcher = pattern.matcher(location);
    if (matcher.matches()) {
        latitude = Double.valueOf(matcher.group(1));
        longitude = Double.valueOf(matcher.group(2));
    }

if you need a Location object:

Location targetLocation = new Location("");//provider name is unnecessary
targetLocation.setLatitude(latitude);//your coords of course
targetLocation.setLongitude(longitude);
