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"

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

}
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

How to integrate Google maps with slide menu in Android

I have completed the google maps and slide menu individually.
I can not combine both into one.
Because google maps extends FragmentActivity.
For slide menu i have to use Fragement.
I try to convert the FragmetActivity to Fragment.
But i come to know that that is not possible.
I can not get any example for google map with slide menu.
Any one can provide me a example or link for google map with slide menu.
Please help me resolve my problem.
Here i attached my SlideActivity.java

Android: Navigation Drawer + Fragment + NestedFragment + SupportMapFragment

I have been reading every possible threads on stackoverflow for the past two days, and I can't figure out where my issue is... Experiencing a new error every time I bring a "fix"
Before the code, the end state: I'm trying to have a navigation drawer between multiple fragments. One of them is a restaurant search that display search results in a SupportMapFragment.
I don't get errors when I first load my fragment that contains the map, but I get error when I switch to another fragment thanks to NavigationDrawer, and I get an error when I'm pressing the back button, plus many other goodies.
Here is my code:
NavigationDrawer.java

Tabs should be placed along the top of an app, below the action bar - as stated in the android design guidelines.
Please spend some time looking at these guidelines for tabs here (and the rest of the guidelines), they're essential for developing android apps!

Android ActionBarCompat - Navigation Drawer with multiple fragments

Im new to the ActionBarCompat library.I want to develop an app which contains multiple fragments. Here is what i want to do
1.How to open a fragment when user select that from Navigation Drawer.
2.How to set a startup fragment which displays startup layout (example- In Google plus app,first its displays news feeds.when we select profile item from the side menu,then its hide the side menu/Navigation drawer and displays the profile layout)
Currently i have side menu and one fragment.
Here is the tutorial that i used to follow- wptrafficanalyzer

If you are going to use a slide out menu I recommend you use this slidemenu library I use it in my applications and it allows you to place whatever you want in the slide out menu, the menu is just a frame layout and you can put whatever you want in it (Listview, GridView, or even just a picture)

I am assuming by side menu you meant Navigation Drawer. You can find an answer in the below link.
Navigation Drawer with backword compatibility android
Do read
http://developer.android.com/design/patterns/navigation-drawer.html
Fragment is hosted by a Activity. So you need a container in the activity layout.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout // container to which you add or replace fragments
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>
Initially you don't click any item. So initially add fragment1 to the container.
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
On click of listitem based on the position
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();

android actionbarcompat is supported library for below android versions.In this you should do some modifications in code.I am giving some sample code with supported library
code:
public class SliderScreen extends ActionBarActivity {
