android: google map api always starts showing from africa

I am using a map fragment to show a map. But when the map starte it shows some location in africa and then shifts to the place i wanted. i have tried few solutions in the stackoverflow, which didnt work, it still starts from africa
CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(26.588527, 77.519531));
CameraUpdate zoom = CameraUpdateFactory.zoomTo(4);
mMap.moveCamera(center);
mMap.animateCamera(zoom);
another solution:
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(26.588527, 77.519531), 4));

You can configure initial map state:
using cameraTargetLat, cameraTargetLng, cameraZoom XML attributes, e.g.:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:cameraTargetLat="26.588527"
map:cameraTargetLng="77.519531"
map:cameraZoom="4"/>
programmatically using GoogleMapOptions, e.g.:
CameraPosition indiaPosition = new CameraPosition.Builder()
.target(new LatLng(26.588527, 77.519531))
.zoom(4)
.build();
GoogleMapOptions mapOptions = new GoogleMapOptions().camera(camera)
SupportMapFragment map = SupportMapFragment.newInstance(mapOptions);

Try this:
//setting India region in google maps
LatLngBounds INDIA = new LatLngBounds(
new LatLng(7.2, 67.8), new LatLng(36.5, 93.8));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(INDIA.getCenter(), 5));
this would set India region on the map.

Try this :
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(26.588527, 77.519531), 11.5f), 4500, null);
works very well !!

Create MapView Programmatically in Android MapsV2

Android: While creating Map
I am getting the Blank page.I have a valid API key also and set it in Manifest.
my activity.
relativeLayout = new RelativeLayout(context);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
relativeLayout.setLayoutParams(layoutParams);
GoogleMapOptions googleMapOptions = new GoogleMapOptions();
googleMapOptions.mapType(GoogleMap.MAP_TYPE_NORMAL)
.compassEnabled(false).rotateGesturesEnabled(false)
.tiltGesturesEnabled(false);
googleMapOptions.camera(new CameraPosition(new LatLng(0, 0), 3, 0,
0));
mapView = new MapView(context, googleMapOptions);
mapView.onCreate(new Bundle());
relativeLayout.addView(mapView);
Double[][] latlang = mapData.getLatlang();
marker = new Marker[mapData.getLatlang().length];
for (int i = 0; i < mapData.getLatlang().length; i++) {
this.marker[i] = mapView.getMap()
.addMarker(
new MarkerOptions()
.position(
new LatLng(latlang[i][0],
latlang[i][1]))
.title(" ")
.snippet(" "));
}

I had the same issue, because I was creating the MapView inside a Fragment and forgot to add the onResume method to the fragment code.
mapView map = new MapView(getActivity(), options));
map.setClickable(true);
map.onCreate(savedInstanceState);
map.onResume();
Hope this helps someone

Add setContentView(relativeLayout); after this line relativeLayout.addView(mapView); It'll solve your problem.

MapView, fixed size of OverlayItem drawable

I use osmdroid which is based on Google Map API v1. When I zoom in/out the map my markers are scaling accordingly but I want them to have fixed size. So how can I prevent scaling of a Drawable (used as a marker of OverlayItem) when I zoom in/out the map?
I create Drawable for the marker using BitmapDrawable(scaledBitmap)

for fix size u add a popupview on a geopoint which is fix size by setting view params and set this drawable as a background
View popUp = getLayoutInflater().inflate(R.layout.map_popup, map, false);
MapView map = (MapView) findViewById(R.id.mapview);
MapView.LayoutParams mapParams = new MapView.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
<geopoint>,
<x offset if required>,
<y offset like pinHeight>,
MapView.LayoutParams.BOTTOM_CENTER);
map.addView(popUp, mapParams);

Marker(overlay) of the google map disappears while changing the orientation of the device

I am using the following code for showing the marker in the current location...but when i change the orientation of the device marker disappears..?
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = Activity.this.getResources().getDrawable(R.drawable.icon);
MyItemizedOverlay itemizedOverlay = new MyItemizedOverlay(drawable ,Activity.this);
GeoPoint point = new GeoPoint( (int)(location.getLatitude()*1000000),
(int)(location.getLongitude()*1000000));
OverlayItem overlayitem = new OverlayItem(point, "Current Location :","+acTextView.getText());
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
MapController mapController = mapView.getController();
mapController.animateTo(point);
mapController.setZoom(14);
How to handle the orientation in the mapview..?

Actually, when orientation of device changes the Activity restart..I put the following attribute in my manifest.xml and my problem is solved now :
android:configChanges="orientation"

How to plot a pre-build map from google maps on a MapView

I'm trying to read a map from a link (http://maps.google.com/maps/ms?msid=216892338463540803496.000494dd57eb5ebce6db2&msa=0) and plot it on a MapView, is it possible?

As you posted more information in my previous answer ("but I don't want to parse the KML and plot point by point. I was wondering if theres a way to plot all at once"), I can now redifine my answer.
You should try these lines and adapt it to your needs:
Intent mapIntent = new Intent(Intent.ACTION_VIEW);
Uri uri1 = Uri.parse("geo:0,0?q=http://code.google.com/apis/kml/
documentation/KML_Samples.kml");
mapIntent.setData(uri1);
startActivity(Intent.createChooser(mapIntent, "Sample"));
Unfortunately, you won't have any control, as this is not a MapActivity.
If you plan to add more stuff on your map, you have to try my first proposal and parse yourself the kml!

You can draw on the Map with Overlays

Look at this tutorial: http://codemagician.wordpress.com/2010/05/06/android-google-mapview-tutorial-done-right/
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
List<Overlay> mapOverlays = mapView.getOverlays();
Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable,this);
GeoPoint point = new GeoPoint(30443769,-91158458);
OverlayItem overlayitem = new OverlayItem(point, "Laissez les bon temps rouler!", "I'm in Louisiana!");
GeoPoint point2 = new GeoPoint(17385812,78480667);
OverlayItem overlayitem2 = new OverlayItem(point2, "Namashkaar!", "I'm in Hyderabad, India!");
itemizedoverlay.addOverlay(overlayitem);
itemizedoverlay.addOverlay(overlayitem2);
mapOverlays.add(itemizedoverlay);
}
#Override
protected boolean isRouteDisplayed()
{
return false;
