First install Google play service and if you are using Android 2.2 then use this code

public class MainActivity extends FragmentActivity {    
    @Override
     protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);    
        SupportMapFragment fragment = new SupportMapFragment();
        getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
    }    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}
