Does Google Maps Android API locate me automatically?

I am working with Google Maps Android API V2.
When my map fragment is loaded it shows my location automatically (with the blue dot). Why does this happen? Is my location history affecting or is the default working mode?
Does this code cause it?:
googleMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
#Override
public void onMyLocationChange(Location location) {
googleMap.setOnMyLocationChangeListener(null);
}
});
I have commented this piece of code but the map is still showing the blue dot.
If this is not happening because of the history, would this piece of code be enough to get user location or do I need to use LocationManager class as described in other questions?

Try to use
googleMap.setMyLocationEnabled(true/false);
to control showing your location on map. I think it is enough to turn the setting on to make your location work with Google Maps, without need to use LocationManager etc.

Default current location pin in Skobbler map

I am using skobbler map for Android. I do not require current location to pointed on the map, so I am not registering for the current location listener and skobbler map itself adds an default current location pin on the map. Please check the image attached. , please tell me how to not display this. And, by default the maps takes to Berlin, Germany can this be avoided? If yes, how?

You can set the behavior of the default position annotation with mapView.getMapSettings().setCurrentPositionShown(false).
To center the map on a desired location use mapView.centerMapOnPosition(skPosition).
Where mapView is your SKMapSurfaceView instance.

Please check the below code hope its help you.As its working at my end.
#Override
public void onCurrentPositionUpdate(SKPosition skPosition) {
this.currentPosition = skPosition;
SKPositionerManager.getInstance().reportNewGPSPosition(this.currentPosition);
mapView.animateToLocation(skPosition.getCoordinate(), 7);
mapView.animateToZoomLevel(7);
}

You can try to call in onSurfaceCreated:
SKCoordinate coord = new SKCoordinate(-37.585162f, 40.418143f);
mapView.setPositionAsCurrent(coord, 0, true);
mapView.setZoom(4);

How to detect a longpress guesture with Google Map V2?

I am an android fresh man and developing a small app with Google Map V2.
I want to get the WGS84 (i.e. LatLng)position when longpress on the MAP.
Several methods are tried as the answers in other topic but the longpress guesture still could not be detected.
Can anyone help on this to provide some sample code for me?

Have you tried this?
mMap.setOnMapLongClickListener(new OnMapLongClickListener() {
#Override
public void onMapLongClick(final LatLng point) {
}
});

Google Maps API v2 invoke behaviour of clicking mylocationbutton

I have a fully working GoogleMap and I can show my userlocation with the call
mMap.setMyLocationEnabled(true);
What I want to accomplish is the functionality of the actual click on the button that now appears on the GoogleMap (I.e animating the map to the userlocation with correct zoom etc).
The functionality is there in the GoogleMap-object already, how do I use it?
I do not want to use a LocationListener or such to accomplish this, I just want to "call the same code" that gets called when I click the button on the map. Can it be that simple?
Thanks in advance.
EDIT:
What I basically want to do is to center the map at the user location, exactly the way that the GoogleMap centers at user location when I click the button. Like this:
GoogleMap mMap = this.getMap();
if(mMap != null) {
mMap.setMyLocationEnabled(true);
//TODO center the map on mylocation
}
EDIT:
Apparently Google is working on this. http://code.google.com/p/gmaps-api-issues/issues/detail?id=4644

This is how I do to navigate to the center of the map when we get the first location-update.
my class header:
public class FragActivity extends SherlockFragmentActivity implements OnMyLocationChangeListener
private GoogleMap mMap;
my mMap-setup:
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = customMapFragment.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null)
setUpMap();
}
setUpMap-method:
private void setUpMap() {
mMap.setMyLocationEnabled(true);
mMap.setOnMyLocationChangeListener(this);
}
and my onlocationchange:
#Override
public void onMyLocationChange(Location lastKnownLocation) {
CameraUpdate myLoc = CameraUpdateFactory.newCameraPosition(
new CameraPosition.Builder().target(new LatLng(lastKnownLocation.getLatitude(),
lastKnownLocation.getLongitude())).zoom(6).build());
mMap.moveCamera(myLoc);
mMap.setOnMyLocationChangeListener(null);
}
Works like a charm

Not really sure why the other answers are talking about OnMyLocationChangeListeners. This is not what was asked in the OP. What was asked was how to replicate the exact behavior of clicking on the MyLocationButton, which is actually more complex than just animating the camera to the user's location. The button does different things depending on what zoom level you're currently on.
For example, when you're zoomed way out, clicking the button will animate you to your location while zooming you in, whereas if you're already at certain zoom levels, clicking the button will only animate you to your location while maintaining the current zoom level.
Rather than painstakingly trying to replicate this behavior, wouldn't it be great if we could simply get a reference to the MyLocationButton and just, you know, click it? Well, this is the current best way I've found to do just that:
#OnClick(R.id.fabMyLocation)
public void onMyLocationClick(FloatingActionButton fabMyLocation) {
View myLocationButton = ((View) mapFragment.getView().findViewById(Integer.parseInt("1")).getParent())
.findViewById(Integer.parseInt("2"));
myLocationButton.performClick();
}
Yeah, it's not pretty, and relies on hardcoded IDs that may change in future versions of the Google Maps API. But this method of retrieving the button is based off of this highly rated answer from 2013 and so far, as of Google Play Services 8.4.0, still works flawlessly.

Update February 2013:
This is now possible. You can now set the map's OnMyLocationChangeListener. Receive an update as you want and move the camera accordingly.
This is not possible. I've found that the GoogleMap in Android is quite limited in the information that it gives you. It simply doesn't give you direct access to the user location updates or to the button that the user can press (you can only enable/disable it, not simulate a press).
You must implement the LocationSource and LocationListener interfaces and use a LocationManager to get updates from the device and use them to send them to the map.
You could then add your own custom button to the overlay to replicate the default button and use your own camera and zoom controls to simulate the functionality.

Android: MapOverlay - Current location

I am currently creating an Android application, that shows the user its current location on Google Maps. I currently have it working so brings up the location, zoomed in.
However, I want the location to be pin-pointed. I have attempted to try and follow the HelloMapView tutorial, but have been having difficulty. How do I modify what the tutorial is saying, to make the Overlay, show the current location?
Also, I have been getting an error, with the getDrawable part of the following:
Drawable drawable = ((Object) this.getResources()).getDrawable(R.drawable.androidmarker);
ItemizedOverlay itemizedoverlay = new ItemizedOverlay(drawable, this);
Also, whereabouts do I paste this:
itemizedoverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedoverlay);
Thank you.
