Hi Friends
I want to display user's current location in Google map and add marker of his location in the map and how can i Update their location in google map after every second ..???
myLocationOverlay = new MyLocationOverlay(this, mapView);
mapView.getOverlays().add(myLocationOverlay);
myLocationOverlay.enableMyLocation();
myLocationOverlay.runOnFirstFix(addfirststandort);
java file
public class MYGIRNE extends FragmentActivity {
GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mygirne);
SupportMapFragment fm = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
// Getting Map for the SupportMapFragment
map = fm.getMap();
if(map!=null){
// Enable MyLocation Button in the Map
map.setMyLocationEnabled(true);
LocationManager manager=(LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria=new Criteria();
String provider =manager.getBestProvider(criteria, true);
Location cloc=manager.getLastKnownLocation(provider);
double lat=0;
double lng =0;
lat =cloc.getLatitude();
lng= cloc.getLongitude();
LatLng latlng = new LatLng (lat,lng);
map.moveCamera(CameraUpdateFactory.newLatLng(latlng));
map.animateCamera(CameraUpdateFactory.zoomTo(15));
map.addMarker(new MarkerOptions()
.title("Your Current Location")
.position(latlng));
.icon(BitmapDescriptorFactory.defaultMarker(
BitmapDescriptorFactory.HUE_AZURE)));
}
}
xml file

android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

also include the following in your manifest file
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="enter your APIKEY" />
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
this code should be an element of application
then include this under the uses permission of your manifest file
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<!-- External storage for caching. -->

<!-- My Location -->

<!-- Maps API needs OpenGL ES 2.0. -->

i hope this helps

I'm trying to run simple demo app of Google Maps. I've referred standard article.
But I'm getting Error inflating class fragment exception.
I've updated mt manifest properly. Registered for Map API key. Install google-play-services and linked it to my current project. Extended my activity from FragmentActivity, still it doesn't work.
Am I doing anything wrong?
I also referred Error inflating class fragment but to no avail.
Any help appreciated.

Change this
<uses-sdk
android:minSdkVersion="11"
to
<uses-sdk
android:minSdkVersion="12"
If you have 11 you will be using SupportMapFragment. Consider this
https://developer.android.com/about/dashboards/index.html?utm_source=ausdroid.net
Looking at the link it is better to change to 12
Change this
public class MainActivity extends FragmentActivity
to
public class MainActivity extends Activity
Also getMap() can return null. Better check the availability of google map services.
You are also missing
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
in manifest file
https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2
You can also remove
<permission
android:name="com.android.googlemapsdemo.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
and this
<uses-permission android:name="com.android.googlemapsdemo.permission.MAPS_RECEIVE" />
I think you should change this
class="com.google.android.gms.maps.MapFragment"
to
class="com.google.android.gms.maps.SupportMapFragment"
Because your minsdk="11"
also change this
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
to
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();

Providing the link follow where you can get the map
and for marking your location you this code
// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;
// create marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps");
// Changing marker icon
marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));
// adding marker
googleMap.addMarker(marker);
How can I highlight an area/region on Google Maps v2 Android? I also have a list of geopoints of that particular region. It needs to highlight that region when you scroll to that region. It needs to fill color for nearby region to differentiate from each other so each region should have a different color.
You need to draw a polygon by selecting some points on map. Here is the code.
MainActivity.java
public class MainActivity extends FragmentActivity implements
OnMapClickListener,
OnMapLongClickListener,
OnMarkerClickListener {
private GoogleMap myMap;
Location myLocation;
boolean markerClicked;
PolygonOptions polygonOptions;
Polygon polygon;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager manager = getSupportFragmentManager();
SupportMapFragment mapFragment = (SupportMapFragment) manager
.findFragmentById(R.id.map);
myMap = mapFragment.getMap();
myMap.setMyLocationEnabled(true);
myMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
myMap.setOnMapClickListener(this);
myMap.setOnMapLongClickListener(this);
myMap.setOnMarkerClickListener(this);
markerClicked = false;
}
#Override
public void onMapLongClick(LatLng point)
{
myMap.addMarker(new MarkerOptions()
.position(point).title(point.toString()));
markerClicked = false;
}
#Override
public boolean onMarkerClick(Marker marker)
{
if(markerClicked)
{
if(polygon != null)
{
polygon.remove();
polygon = null;
}
polygonOptions.add(marker.getPosition());
polygonOptions.strokeColor(Color.BLACK);
polygonOptions.strokeWidth(5);
polygonOptions.fillColor(0x884d4d4d);
polygon = myMap.addPolygon(polygonOptions);
marker.remove();
}
else
{
if(polygon != null)
{
polygon.remove();
polygon = null;
}
polygonOptions = new PolygonOptions().add(marker.getPosition());
markerClicked = true;
marker.remove();
}
return true;
}
#Override
public void onMapClick(LatLng point)
{
Toast.makeText(getApplicationContext(),
"Long Press to select locations", Toast.LENGTH_LONG).show();
}

now use long press to select points on map and click on marker will draw polygon accordingly.. I thing this will help.

for details https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/model/Polygon
You just draw a Polygon on your map and fill it with the color you need.
