Zoom to the current location not working with navigation drawer

I'm developing an Android Application which is consists of a Navigation drawer and a Google Map. I have successfully developed my Navigation Drawer and connect my Map into it. The thing is I need my Map to Zoom to the current location.
Here is the code I used in MapsActivity.java.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
mMap.setMyLocationEnabled(true); // Identify the current location of the device
mMap.setOnMyLocationChangeListener(this); // change the place when the device is moving
Location currentLocation = getMyLocation(); // Calling the getMyLocation method
if(currentLocation!=null){
LatLng currentCoordinates = new LatLng(
currentLocation.getLatitude(),
currentLocation.getLongitude());
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(currentCoordinates, 13.0f));
}
}
Here I implemented getMyLocation() method.
//Zoom to the current location
private Location getMyLocation() {
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); // Get location from GPS if it's available
Location myLocation = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
// Location wasn't found, check the next most accurate place for the current location
if (myLocation == null) {
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
// Finds a provider that matches the criteria
String provider = lm.getBestProvider(criteria, true);
// Use the provider to get the last known location
myLocation = lm.getLastKnownLocation(provider);
}
return myLocation;
}
Here is How I gave MapsFragment in to NavigatioDrawerActivity.
fragment = new MapFragment();
When I run this alone (Insert intent filter to MapsActivity in Manifest) it works perfect. But, when I'm running the Nvigation Drawer as MainActivity this function is not working. Only the default Map is loading.
What should I do?
-edit-
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
My Maps.xml is like this.
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}

try this ..
map.animateCamera(CameraUpdateFactory.newLatLngZoom((sydney), 13.0f));
you have not given by in float. so its not working.. try this..

try this
map.moveCamera(CameraUpdateFactory.newLatLngZoom(currentCoordinates, 13));
In XML
<com.google.android.gms.maps.MapView
android:id="#+id/mapView"

In JAVA Activity

switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity())) {
case ConnectionResult.SUCCESS:
mapView = (MapView) findViewById(R.id.mapView);

mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLatitude, mLongitude), 13));
}
break;
case ConnectionResult.SERVICE_MISSING:
break;
case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
break;
default:
}
}
call like this
initializaMap(savedInstanceState);

it will not work because the navigation drawer takes a fragment and you are initializing :
fragment = new MapFragment();
so it takes the MapFragment default layout .
you must to change the updateDisplay to takes an activity not a fragment . In another words change the navigation drawer to activities instead of fragments

reposition a marker when I press button android API V2

I have the following code and, when I press a menu button I would like to reposition the same marker and the camera but I do not have idea how to do it, I've read oficial documentation but I haven't found info. I'm using repositionMarker() method to do it, but Im not sure what to do. Thanks
public class Init extends AppCompatActivity implements OnMapReadyCallback
{
private MapFragment map;
static final LatLng PERTH = new LatLng(19.0436, -98.1981);
private CameraUpdate camaraloc, camaraloczoom;
private Marker markerloc;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_inicio);
map = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
if (map != null)
{
map.getMapAsync(this);
}
}
#Override
public void onMapReady(GoogleMap map)
{
map.setMyLocationEnabled(true);
camaraloc = CameraUpdateFactory.newLatLng(PERTH);
camaraloczoom = CameraUpdateFactory.zoomTo(8);
map.moveCamera(camaraloc);
map.animateCamera(camaraloczoom);
markerloc = map.addMarker(new MarkerOptions().position(PERTH)
.title("city").snippet("esp").icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu_inicio, menu);
return true;
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
case R.id.action_settings:
Toast.makeText(this, "name marker: "+markerloc.getTitle(), Toast.LENGTH_SHORT).show();
reposicionMarker();
return true;
}
return super.onOptionsItemSelected(item);
}
public void repositionMarker()
{
camaraloc = CameraUpdateFactory.newLatLng(new LatLng(16.65, -91.8658));
camaraloczoom = CameraUpdateFactory.zoomTo(15);
if ( markerloc != null )
markerloc.remove();
markerloc.setPosition(new LatLng(16.65, -91.8658));
// here is where I dont know what to do
}
}

Calling setLocation on the Marker should work, for changing its location. What seems to be your problem is that you are actually removing the marker right before you set the new location.

Android: GoogleMaps on fragment LongPressClick doesn't work

I want to pin a new mark on my map but method onMapLongClick didn work.

As you can see I have both onMapClick and onMapLongClick methods but when I click on map nothing happens. I also have implement OnMapLongClickListener and OnMapClickListener. What am I doing wrong?
Thanks in advance.

Your class implements the listener but you don't set it:
googleMap.setOnMapLongClickListener(this);
same with the normal click listener:
googleMap.setOnMapClickListener(this);

ActionBarSherlock Options menu not displayed on Google Maps fragment

I am using ActionBarSherlock to display fragmented tabs on Android 2.2

does it not appear because it's in a fragment? Is there any way I can enable my own custom menu inside the google map fragment?
All answers and discussions are welcome,
let me know if you need to view any of my adapter classes that handle the fragments, or the .xml files.

you could try to save your menu in menu folder and can inflate that menu like this
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
super.onCreateOptionsMenu(menu, inflater);
}

how to show map of specific city in google map when app start

below is my code which display map of all world i want when application start is show specific city not world map i follow this tutorial http://android-er.blogspot.com/2013/01/google-maps-android-api-v2-example-draw.html every thing work fine but i want when app start first time is display specific city map not all global map i dont want show globap map like this image http://1.bp.blogspot.com/-dwjqTWCdONg/UObUk1syAFI/AAAAAAAAGy8/S43YMKuXZRc/s1600/screen_MapsAPIv2_Polygon.png on app start i want specific city map like newyork for example.

add this code to your onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
.
.
.
// define point to center on
LatLng origin = new LatLng(40.67, -73.94);
CameraUpdate panToOrigin = CameraUpdateFactory.newLatLng(origin);
myMap.moveCamera(panToOrigin);
// set zoom level with animation
myMap.animateCamera(CameraUpdateFactory.zoomTo(14), 400, null);
}

After the onClikListener are setted (into onCreate), put this code
LatLng NewYork= new LatLng(40.714623,-74.006605);
CameraPosition camPos = new CameraPosition.Builder().target(NewYork).zoom(14).build();
CameraUpdate cam = CameraUpdateFactory.newCameraPosition(camPos);
myMap.animateCamera(cam);
It will animate your map and move the camera to NY
