get updated and lastknownlocation in a fragment

Being very new to java, I am very confused about getting lastknownlocation and updated location.
Over last few days, I have managed to get the mark on a predefined location, but I am struggling very much on getting my current location using fusedlocationproviderclient.
I will be grateful if somebody kindly help me on getting this.
I am using :
compile 'com.google.android.gms:play-services-maps:11.8.0'
compile 'com.google.android.gms:play-services-location:11.8.0'
Though not for the updated location, below is the code for marker at a fixed position
public class SecondFragment extends Fragment implements OnMapReadyCallback {
private GoogleMap mMap;
public GoogleMap getMap() {
return mMap;
}
public static SecondFragment newInstance() {
SecondFragment fragment = new SecondFragment();
return fragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_maps, null, false);
SupportMapFragment mapFragment = (SupportMapFragment) this.getChildFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return view;
}
#Override
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));
}
}

I am using this to get my location:
LocationManager locationManager = (LocationManager)getActivity().getSystemService(getContext().LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,locationListener);
Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
and listener for this:
LocationListener locationListener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
Log.e("osm", "onLocationChanged: "+location.getLongitude() );
}
#Override
public void onStatusChanged(String s, int i, Bundle bundle) {
}
#Override
public void onProviderEnabled(String s) {
}
#Override
public void onProviderDisabled(String s) {
}
};
Do not forget write to manifest this:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
and runtime permission for new version of android(6 and up) :
String[] permission = new String[]{Manifest.permission.CALL_PHONE,Manifest.permission.ACCESS_FINE_LOCATION};
ActivityCompat.requestPermissions(this,permission,PERMISSON_CODE);`

Google maps v2 not initializing in fragment

I want to show my current location using Google maps v2 from a fragment however the Google maps is not initializing on start up. When i run the application, it is nor crashing but the map is not showing my current location neither is it displaying anything. I have used this code on my activity and it is fully functional.
Below is my java code:

first of all Chaeck permission in manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
then check method for current location
private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
marker = map.addMarker(new MarkerOptions().position(loc));
if(map != null){
map.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
}
}
};
then use
mMap.setOnMyLocationChangeListener(myLocationChangeListener);
and be patience map take laoding time depend on you network speed
comment if any query

First check your permissions and your google api key in your manifest
Your xml layout must be something like this without any thing else:
. <fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.isg_biz.isg_tracking.MainActivity" />
You have to implement OnMapReadyCallback, then
your code should be something like this in onCreate() :
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Do not to copy and past the same xml code literally you have to change (tools : .....) to same that exist in your xml
for documentation, java code & more Please read :
https://developers.google.com/maps/documentation/android-api/map-with-marker

Google map not showing my current location

I wrote code in Android studio to display my location in a Google Map fragment but it is not doing so. The map is being displayed but the coordinates I want is not getting marked. The code is the following:
public class SEMapTab extends Fragment implements OnMapReadyCallback {
private View rootView;
private MapFragment mMapFrag;
private GoogleMap mMap;
private LocationManager locationManager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
rootView = inflater.inflate(R.layout.single_entity_map, container, false);
} catch (InflateException e) {
}
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
if (mMapFrag == null) {
super.onViewCreated(view, savedInstanceState);
FragmentManager fragment = getActivity().getFragmentManager();
mMapFrag = (MapFragment) fragment.findFragmentById(R.id.map);
mMapFrag.getMapAsync(this);
}
locationManager = (LocationManager) getActivity().getSystemService(Context.LOCATION_SERVICE);
if (ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
//if network provider is enabled
if(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
{
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
double Latitude= location.getLatitude(); //Get latitude
double Longitude = location.getLongitude(); //Get longitude
LatLng latLng= new LatLng(Latitude, Longitude);
//Map latitude and longitude
mMap.addCircle(new CircleOptions().center(latLng).fillColor(Color.BLUE).radius(10));
//Zoom in to current location
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,18));
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
});
}
//else if gps provider is enabled
else if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
{
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, new LocationListener() {
#Override
public void onLocationChanged(Location location) {
double Latitude= location.getLatitude(); //Get latitude
double Longitude = location.getLongitude(); //Get longitude
LatLng latLng= new LatLng(Latitude, Longitude);
//Map latitude and longitude
mMap.addCircle(new CircleOptions().center(latLng).fillColor(Color.BLUE).radius(10));
//Zoom in to current location
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,18));
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
}
#Override
public void onProviderDisabled(String provider) {
}
});
}
}
#Override
public void onMapReady(GoogleMap googleMap)
{
}
}
I have also included the necessary permissions in AndroidManifest.xml file
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
The Map fragment is opening but there is no circle getting marked at my current location. Alternatively, if I hard code a GPS location in OnMapReady function, then that is gettig marked and is working fine. I request you to help me resolve this issue.

At onMapReady add googleMap.setMyLocationEnabled(true). No need to handle "manually" the location manager and these providers. Just be sure that user has given the permission to the app to access his location before call this, otherwise the app will crash.

onLocationChanged never called

I don't know why my map doesn't call to onLocationChanged when I press my button. These are my permissions:
<uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />

The map is properly displayed, but it does not get my location :(.
Any idea ?
UPDATE
Finally I was able to solve de problem implementing Google API Client and Fused Location Api.

Does the app has permission ? Did you handle the not granted case ?
And those provider(s) the app requests are enabled ?
Did you debug the app, and reach the any of locationManager.requestLocationUpdates line ?
Seems like the app is not requesting due to lacking of 1 and 2

Cannot Zoom Android Map fragment to the current location

This is not the first question im posting regarding this matter in Stack Overflow. I really need help to zoom my map fragment to the current location. Please don't think I'm not trying anything. I tried a lot.
I need to zoom my map to the current location and no matter how hard I tried map zoom to another location not my current location. Cannot even possibly think what is happening here.

I think I've dome a small mistake and it zooms to another location and it is not even close to my country.
Here is the image of my zooming location.
Someone please tell me how to zoom my map fragment to the current location.
Any kind of help may appreciated. :)

Added getMyLocation() inside onMapReady()

Here it is:
#Override
public void onMapReady(GoogleMap googleMap) {
map = googleMap;
Location myLocation = getMyLocation();
LatLng latLng = new LatLng(myLocation.getlatitude(), myLocation.getLongitude());
map.animateCamera(CameraUpdateFactory.newLatLngZoom(
latLng
, 15));
}
and
private LocationRequest mLocationRequest;
private static final long INTERVAL = 1000 * 1000;
private static final long FASTEST_INTERVAL = 1000 * 900;
#Override
public void onConnected(Bundle bundle) {
mLocationRequest = new LocationRequest();
mLocationRequest.setInterval(INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
this will call onLocationChanged();

Try calling onLocationChanged(), from within getMyLocation()

Firstly check whether you are receiving location coordinates values or not, if receiving try using this one
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15));
This could be useful for you.
