如何从Activity中启动FragmentActivity？

我的MainActivity是一个闪屏,我想接下来为FragmentActivity加注星标.

我需要的东西而不是,例如:

    startActivity(new Intent("com.example.manager.MyFragmentActivity"));

TIA.

我在课堂上有这个

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

import com.coffeeandcookies.ushuaiamovil.R;

public class LayMapa2 extends FragmentActivity
{
    @Override
    protected void onCreate(Bundle arg0) 
    {
        setContentView(R.layout.lay_mapa2);
        super.onCreate(arg0);
    }
}

这在我的xml中

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.SupportMapFragment" />

这在我最明显的

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <uses-feature android:glEsVersion="0x00020000"
              android:required="true"/>

    <permission
        android:name="com.coffeeandcookies.usuahiamovil.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="com.coffeeandcookies.usuahiamovil.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

我有一个旧的应用程序,我正在尝试进行更新以添加地图.Google服务在eclipse中添加到我的工作区,并在我的项目中作为库引用创建.在清单中添加了Mapkey和权限.

我阅读了很多教程,但我无法解决下面的问题:
