My onLocationChange method is not being called

I have downloaded an android map project. And now i want to do something like this and i have implemented all of this thing but i am getting that on Location Changed method is not being called in my project but in other this method is being called. I am saying this because dialog is not being dismissed, zooming, and icon is not working,
Is there is way to solve this? or can we do all of that thing in on Map Ready which i have done in on Location change.

this is the exact answer of my question.
In that case, you have to request location updates as described at developers.google.com/android/reference/com/google/android/g‌​ms/…. You should do this in your onCreate() method. Your current location listener is from the incorrect package for your use. Use the location listener from the Google API package –
They should all be from the com.google.android.gms package. Make sure you are uniform when using the API

In order to use the onLocationChanged(Location) callback, you need to register your location listener with the location manager. Something like:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
Since you have implemented the locationListener interface, for you it will look something like:
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);

When placing markers on map activity the camera move to the marker

I am using nearbyPlaces web service and I have a problem, I am putting a marker on the map for each pharmacie that it finds, but the camera always move to the marker and it does not stay in the current user position dot.
this is the code

googlePlacesData = downloadUrl.readUrl(url);

} catch (Exception e) {

}

Any help please? thanks in advance

Your posted code includes these lines:
//move map camera
mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
mMap.animateCamera(CameraUpdateFactory.zoomTo(14.0f));
Sounds like you don't want to move the camera, so you should probably delete them.

Getting the phone number of nearby place

I've been following this tutorial on displaying nearby places, in my case I need nearby hospitals. I'm able to show my current location and display nearby hospitals. But what I want to do is add the telephone number of those hospitals being displayed. I've tried adding formatted_phone_number in my code but it doesn't display the correct phone number but instead displays "-NA-" which is the default in the event that there's no number available.
Any help would be greatly appreciated thanks!

In MapsActivity.class, function getUrl() is taking "Hospital" as one of the arguments which is not in the list of supported types. So, the result type is default, since it doesn't match any supported types.
The response will give you all the places nearby search request for places of type 'default'. To make a request to Nearby Places API to get nearby hospitals, pass hospital instead of Hospital.
In the code, you make a request to Nearby Places API, formatted_phone_number is not returned in response. For more information, refer to the documentation.
To get the phone number(formatted_phone_number or international_phone_number) make a request to Place Details API with the PlaceId.
To get more clarity, enter the url in the browser and look at the response.
Hope this helps you. Good luck :)

I am sorry to post the whole code to avoid any confusion by others.I implimented GoogleMap sucessfully in my application and i am getting my current location also.My requirement is to get the address of the location whereever the marker is placed.The marker is draggable,but when i shift or Drag the marker from one place to another i am not getting anything,not even the log.I searched around 2 days for solution.Please try to help me.

You need to add this on your onMapReady method:
mMap.setOnMarkerDragListener(this);

Add following line in onMapReady()
mMap.setOnMarkerDragListener(this);
Get your marker new position and in onMarkerDragEnd() and fetch address from new LatLng:
// New Marker Position
LatLng position = marker.getPosition();
// Remove Old Marker
mCurrLocationMarker.remove();
// Add New marker position
markerOptions.position(position);
// Add Title on Marker
markerOptions.title(getCompleteAddressString(position.latitude, position.longitude));
// Set Draggable
markerOptions.draggable(true);
// Set Icon of Marker
markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA));
// Add marker on map
mCurrLocationMarker = mMap.addMarker(markerOptions);
// Show Info window on marker
mCurrLocationMarker.showInfoWindow();

How to Implement draggable map like uber android, Update with change location

How to implement draggable map like uber? I am using Google maps v2. Actually i got the solution referring this post and sharing my complete solution here

Updated with latest code also included change location with autocomplete
Complete project can be found here
Logic is Simple we need a framelayout and add a map and marker layout inside that framelayout then make maker layout gravity to center and get latitude and longitude of the centre point of the map on camera change
refer this answer
