How to Zoom and get latitude and longitude from mMap.setMyLocationEnabled(true) in Google Map (Android)

I was setting mMap.setMyLocationEnabled(true) and I am successfully getting my current location but...
Not able to zoom to that position.
Not able to get lat and lng from that position
From getting latitude and longitude I am using below code but it gives me null. I am calling below method from onMapReady(Google Map) and passing google map object.
private void goToCurrentLocation(GoogleMap map) {
Log.d("Tag", "inside");
Location loc = map.getMyLocation();
if (loc != null) {
LatLng point = new LatLng(loc.getLatitude(), loc.getLongitude());
Log.d("Tag=", "latlng=" + point);
map.animateCamera(CameraUpdateFactory.newLatLngZoom(point, 15));
}
}
Is there any alternative to getting latitude and longitude as getMyLocation deprecated?

use link provided in the answer to get current location and then zoom over that location using below code:
latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
mGoogleMap.animateCamera(cameraUpdate);

Location query in Google maps in android

I have made an app utilizing Google Maps. I have added a marker of my current location in it. However, as soon as I open the app, I want it to zoom in to my location instead of showing the whole world at the 95302 23535919711008489 location first. How do I accomplish this?

Use animateCamera() as below
#Override
public void onLocationChanged(Location location) {
LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
map.animateCamera(cameraUpdate);
locationManager.removeUpdates(this);
}
Please read the docs

LatLng cameraLatLng = new LatLng(savedLat, savedLng);
googleMap = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
googleMap.animateCamera(CameraUpdateFactory
.newLatLngZoom(cameraLatLng, 7))
savedLat, savedLng your current location longitude and latitude.You can change zoom number ( 7 ) to your fitting.

Turn (rotate)marker position based on direction over the route

I've a route created along with a polyline over google maps api v2 (Android). My custom marker moves along the route which i achieved by creating a thread. I also get the maneuvers (turn-left, turn-right, etc).
Now as my marker starts moving (a car icon), i want it to turn and navigate through the route. I did manage to rotate it, however i want an accurate solution for this query. right now i hard coded the angles and thus rotating my marker along with the " setRoation() method ". However the rotation isn't as it should be and i cannot get its dynamic angles.
Please Help !
Thanks in advance

Hey see following code for rotate marker as per location
double oldlat = 19.180237, oldlong = 72.855415;
double newlat = 19.180237, newlong = 72.855415;
public void rotatemarker() {
Location prevLoc = new Location("service Provider");
prevLoc.setLatitude(oldlat);
prevLoc.setLongitude(oldlong);
Location newLoc = new Location("service Provider");
newLoc.setLatitude(newlat);
newLoc.setLongitude(newlong);
bearing = prevLoc.bearingTo(newLoc);
map.clear();
map.addMarker(new MarkerOptions()
.position(new LatLng(newlat, newlong))
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher))
.anchor(0.5f, 0.5f)
.rotation(bearing)
.flat(true));
oldlong = newlong;
}

Android Google Maps V2, how to get current location by gps/internet

Here I am getting the location, by writing hardcoded latitude and longitude. I used map.setMyLocationEnabled(true);, it gives me the current location in map. But I also want marker to reach upto the my current location.
Can you help to get latitude and longitude of my current position.
private final LatLng LOCATION = new LatLng(22.7515085, 75.8860726);
map = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
map.setMyLocationEnabled(true);
map.addMarker(new MarkerOptions().position(LOCATION).title("It is my current position"));
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(LOCATION, 6);
map.animateCamera(update);

Android Update Current Location

So here is my method for getting the user saved location and then move camera to that location:
private void updatePlaces(){
locMan = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location lastLoc = locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
double lat = lastLoc.getLatitude();
double lng = lastLoc.getLongitude();
LatLng lastLatLng = new LatLng(lat, lng);
if(userMarker!=null) userMarker.remove();
userMarker = theMap.addMarker(new MarkerOptions()
.position(lastLatLng)
.title("You are here")
.icon(BitmapDescriptorFactory.fromResource(userIcon))
.snippet("Your last recorded location"));
theMap.animateCamera(CameraUpdateFactory.newLatLng(lastLatLng), 3000, null);
}
How can i modify this code in order to get the new position only once, compare and then get camera to it?
Thank you in advance.

I don't understand you question, if you run the method updatePlaces() only ones it will getLastKnownLocation only once and updates the user marker only once. could you please be more explanatory on what you are trying to achieve?
