integration of Google maps with location

Step 1>  Download google play service lib project from below URL

 https://github.com/aporter/coursera-android




Step 2> Create a new Project and   add Google-Play-Service lib project  to the GoogleMaps project as library project.

Step 3> In activity_main.xml import fragment  from Layout which supports the SupportMapFragment as below

         (OR)
Write the below code in activity_main.xml


 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        android:id="@+id/fragment1"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

.

step 4> write the following code in MainActivity.xml

package com.example.googlemaps;
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 com.google.android.gms.maps.model.MarkerOptions;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

     
        SupportMapFragment f=(SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.fragment1);
        final GoogleMap gMap=f.getMap();
     
        final LocationManager lManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
        lManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 15000, 1000,new LocationListener()
        {
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub

}

@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub

}

@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub

}

@Override
public void onLocationChanged(Location location)
{
MarkerOptions opt=new  MarkerOptions();
   opt.position(new LatLng(location.getLatitude(), location.getLongitude()));
gMap.addMarker(opt);
gMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 15));

lManager.removeUpdates(this);
}
});
     
     
     
    }


}

Step 6> Generate Your Own google maps API key.


Step 7> replace following code in Manifest.xml file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.googlemaps"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

 
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
 
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">
        <activity
            android:name="com.example.googlemaps.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
 
     
        <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>
        <meta-data android:name="com.google.android.geo.API_KEY"       android:value="Here You have to give your own Google API key"/>
 
    </application>
 
</manifest>
