Android : Not able to Run Android GoogleMap V2 in App

I am trying to run android google map in android app but not able to run it , I follow all the procedure and I created the API Key as Well . Following is the Code:

MainActivity.java :

public class MainActivity extends Activity {

    // Google Map
    private GoogleMap googleMap;

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

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

    @SuppressLint("NewApi")
    private void initializeMap() {
        if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        }
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(), "Sorry, Unable to Show Map", Toast.LENGTH_SHORT).show();
        }
    }

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

}
