Google Maps v2 - set both my location and zoom in

Question

My question is  does anyone know how to set google maps up  to open up both my location and in a zoomed-in view   Currently  the main view opens up to Africa  all the way zoomed out   And so I have been searching for days now  and all I can find are   1  You cannot animate two things  like zoom in and go to my location  in one google map  So if I can figure out how to set the zoom before I set the animate  then this problem would be solved  That tends to be the issue  you can change one  but not both   2  I have found other classes that might be useful  but there is no help on how to set up the code so the class can manipulate the google map   This is the code I have been holding on to so far  some works  some do not  Some I thought might be useful later on   package com MYWEBSITE www   import com google android gms maps CameraUpdateFactory  import com google android gms maps GoogleMap  import com google android gms maps SupportMapFragment  import com google android gms maps model LatLng  import android content Context  import android location Criteria  import android location Location  import android location LocationManager  import android os Bundle  import android support v4 app FragmentActivity  import android view Menu   public class MainActivity extends FragmentActivity   private GoogleMap map      Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout main layout        map     SupportMapFragment  getSupportFragmentManager   findFragmentById R id map   getMap        map setMyLocationEnabled true          LocationSource a    LocationSource  getSystemService Context LOCATION SERVICE         LocationManager b    LocationManager  getSystemService Context LOCATION SERVICE         map setLocationSource a        Criteria criteria   new Criteria        LocationManager locationManager    LocationManager  getSystemService Context LOCATION SERVICE       String provider   locationManager getBestProvider criteria  false       Location location   locationManager getLastKnownLocation provider       double lat    location getLatitude        double lng   location getLongitude        LatLng coordinate   new LatLng lat  lng          CameraPosition Builder x   CameraPosition builder          x target coordinate         x zoom 13          Projection proj   map getProjection          Point focus   proj toScreenLocation coordinate          map animateCamera CameraUpdateFactory newLatLng coordinate        map animateCamera CameraUpdateFactory zoomBy 13          map moveCamera CameraUpdateFactory newLatLng coordinate              LatLngBounds bounds   mMap getProjection   getVisibleRegion   latLngBounds

Try in this way -   public class SummaryMapActivity extends FragmentActivity implements LocationListener    private GoogleMap mMap   private LocationManager locationManager   private static final long MIN TIME   400   private static final float MIN DISTANCE   1000    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout summary mapview        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                mMap addMarker new MarkerOptions   position new LatLng 0  0   title  Marker                         mMap setMyLocationEnabled true        locationManager    LocationManager  getSystemService Context LOCATION SERVICE       locationManager requestLocationUpdates LocationManager NETWORK PROVIDER  MIN TIME  MIN DISTANCE  this          Override public void onLocationChanged Location location        LatLng latLng   new LatLng location getLatitude    location getLongitude         CameraUpdate cameraUpdate   CameraUpdateFactory newLatLngZoom latLng  15       mMap animateCamera cameraUpdate       locationManager removeUpdates this        Override public void onProviderDisabled String provider           TODO Auto-generated method stub      Override public void onProviderEnabled String provider           TODO Auto-generated method stub      Override public void onStatusChanged String provider  int status  Bundle extras           TODO Auto-generated method stub

CommonsWare s answer doesn t not actually work  I found that this is working properly    map moveCamera CameraUpdateFactory newLatLngZoom new LatLng -33 88 151 21   15

It s possible to change location  zoom  bearing and tilt all in one go  It s also possible to set the duration on the animateCamera   call   CameraPosition cameraPosition   new CameraPosition Builder        target MOUNTAIN VIEW          Sets the center of the map to Mountain View      zoom 17                       Sets the zoom      bearing 90                    Sets the orientation of the camera to east      tilt 30                       Sets the tilt of the camera to 30 degrees      build                         Creates a CameraPosition from the builder map animateCamera CameraUpdateFactory newCameraPosition cameraPosition      Have a look at the docs here   https   developers google com maps documentation android views hl en-US moving the camera

The simpliest way to do it is to use CancelableCallback  You should check the first action is complete and then call the second   mMap animateCamera CameraUpdateFactory newLatLngBounds bounds  size x  height  0   new CancelableCallback                       Override                 public void onFinish                         CameraUpdate cu scroll   CameraUpdateFactory scrollBy 0  500                       mMap animateCamera cu scroll                                       Override                 public void onCancel

Its a late answer but I think it will help  Use this method   protected void zoomMapInitial LatLng finalPlace  LatLng currenLoc        try           int padding   200     Space  in px  between bounding box edges and view edges  applied to all four sides of the bounding box          LatLngBounds Builder bc   new LatLngBounds Builder             bc include finalPlace           bc include currenLoc           googleMap moveCamera CameraUpdateFactory newLatLngBounds bc build    padding          catch  Exception e            e printStackTrace              Use this method after loading the map  Cheers

You cannot animate two things  like zoom in and go to my location  in one google map  So use move and animate Camera to zoom  googleMapVar moveCamera CameraUpdateFactory newLatLng LocLtdLgdVar    googleMapVar animateCamera CameraUpdateFactory zoomTo 10

You also could set both parameters like   mMap moveCamera  CameraUpdateFactory newLatLngZoom new LatLng 21 000000  -101 400000   4       This locates your map on a specific position and zoom  I use this on the setting up my map

You cannot animate two things  like zoom in and go to my location  in one google map    From a coding standpoint  you would do them sequentially       CameraUpdate center          CameraUpdateFactory newLatLng new LatLng 40 76793169992044                                                   -73 98180484771729        CameraUpdate zoom CameraUpdateFactory zoomTo 15        map moveCamera center       map animateCamera zoom     Here  I move the camera first  then animate the camera  though both could be animateCamera   calls  Whether GoogleMap consolidates these into a single event  I can t say  as it goes by too fast   -   Here is the sample project from which I pulled the above code     Sorry  this answer is flawed  See Rob s answer for a way to truly do this in one shot  by creating a CameraPosition and then creating a CameraUpdate from that CameraPosition
