Cannot resolve symbol 'OnMapReadyCallback' Issue

Question

I am following Google Maps Android "get started" tutorial- https://developers.google.com/maps/documentation/android/

But I came across an error ""Cannot resolve symbol 'OnMapReadyCallback', which might be a easy fix, but is baffling me. This is the code I have for my import statements for the app:

import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class main extends FragmentActivity implements OnMapReadyCallback {


    // Within which the entire activity is enclosed
    DrawerLayout mDrawerLayout;

    // ListView represents Navigation Drawer
    ListView mDrawerList;

    // ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar
    ActionBarDrawerToggle mDrawerToggle;

    // Title of the action bar
    String mTitle="";

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

Android Manifest:

OnMapReadyCallback just came out in a recent update to the Maps V2 SDK. If you want it, you need to upgrade to a new-enough version of that SDK.

Android Studio users can switch over to compile 'com.google.android.gms:play-services-maps:6.5.87', from the new Play Services granular dependencies, to get this new class and possibly reduce the size of their APK as a side benefit.
