在 GoogleMap 中使用 getMap() 出错

Question

Can anyone tell me what's wrong with my code error and I couldn't solve it and I wondered can you guys tell me what is wrong with my code.

This is my MapsActivity.java

package com.ite.googlemap;

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapsActivity extends FragmentActivity {

GoogleMap Map;
private static final LatLng ITE_COLLEGE_WEST = new LatLng(1.374935, 103.751998);

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

    try{
        if(Map==null) {
            Map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

            Map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
            Map.addMarker(new MarkerOptions().position(ITE_COLLEGE_WEST).title("ITE COLLEGE WEST"));

            Map.moveCamera(CameraUpdateFactory.newLatLngZoom(ITE_COLLEGE_WEST, 0));

            Map.animateCamera(CameraUpdateFactory.zoomTo(15), 2000, null);

        }

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

}

}

This is my activity_maps.xml

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.ite.googlemap.MapsActivity"

class="com.google.android.gms.maps.MapFragment"
/>

This is what happen after I run the app when Messages Gradle Build Pop up
