Put the SHA 1 finger print and package name.

Example: DE:13:23:14:4C:7E:95:F6:27:DC:29:3A:39:9E:84:B9:A7:DE:1F:53;com.example.setmaplocation

Put the generated api key in the manifest file. in meta data tag.

Open Eclipse Windows Android SDK Manager and check whether you have already downloaded Google Play Services or not under Extras section. If not select play services and install the package.

In Eclipse goto File Import Android Existing Android Code Into Workspace. Click on Browse and select Google Play Services project from your android sdk folder. You can locate play services library project from android-sdk-windows\extras\google\google_play_services\libproject\google-play-services_lib.

Then make the following activity. sample code

package com.example.setmaplocation;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

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;

public class MainActivity extends FragmentActivity {

    private GoogleMap googleMap;
    double latitude = 21.0000;
    double longitude = 78.0000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        System.out.println("In Oncreate");

        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);

        return true;

    }

    private void initilizeMap() {


        if (googleMap == null) {
            // Try to obtain the map from the SupportMapFragment.
            googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();
            // Check if we were successful in obtaining the map.
            if (googleMap != null) {

                MarkerOptions marker = new MarkerOptions().position(
                        new LatLng(latitude, longitude)).title("Hello Maps ");

                googleMap.addMarker(marker);

            }
        }

    }

    @Override
    protected void onResume() {
        super.onResume();
        initilizeMap();
    }

}
