Here is my Activity code
package com.example1.heartconnect;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
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.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
public class Maps extends FragmentActivity {
GoogleMap map;
@Override
protected void onCreate(Bundle arg0) {
// TODO Auto-generated method stub
super.onCreate(arg0);
setContentView(R.layout.maps);
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.gmap)).getMap();
map.setMyLocationEnabled(true);
map.setMapType(map.MAP_TYPE_NORMAL);
Location loc = map.getMyLocation();
double lat = loc.getLatitude();
double lon = loc.getLongitude();
LatLng position = new LatLng(lat, lon);
Marker marker = map.addMarker(new MarkerOptions()
.title("Your Location")
.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
.position(position));
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position, 10));
}
}
This is the XML file
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

When I remove these 2 lines and provide Latittude & Longitude manually, the app works and I'm able to see the bare Google Map with a marker at that LatLng
double lat = loc.getLatitude();
double lon = loc.getLongitude();
I've also tried to find the current location in following way :
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);
But the app crashes here too. Plz can anyone suggest me the modifications needed so that I can see my current location on the map... Thnxx in advance :)
Location loc = map.getMyLocation();
didn't wait for your current locationSee the example: http://developer.xamarin.com/recipes/android/os_device_resources/gps/get_current_device_location/
Also see this: http://developer.android.com/training/location/retrieve-current.html
This is the code for getting current location on the map.
and you need to
import google play store into your project as a library
. and add support v4 into your project like Right click yourproject -> select properties ->java build path -> select Libraries Tab -> click Add External JARs, and give path of your support v4 jar
.I am sure this step will help you.
