我认为我已经完成了这两个链接中的所有步骤：

所以请不要将它们作为答案发送。
我已经下载了 Maps API，将其复制到 Eclipse Workspace 中，将其标记为库，并在我的项目中引用了它。但没有成功。我仍然收到错误：
GoogleMap 无法解析为类型
MapFragment 无法解析为类型
这是我的 MainActivity.Java：
package com.mapsapp.mapsappv1;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;
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 {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* function to load map. If map is not created it will create it for you
* */
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override
protected void onResume() {
super.onResume();
initilizeMap();
}
}
这是我的 AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

也许有人有这个错误并且知道如何解决它？
我已经尝试重新启动eclipse，清理项目，从头开始创建项目（实际上是v10或其他东西:)）显然我做错了什么..
任何形式的帮助将不胜感激。但是请不要粘贴我开头提到的两个链接。
编辑：进度报告
@regeme 的评论：import com.google.android.gms.maps.GoogleMap;帮助摆脱错误：GoogleMap cannot be resolved to a type
但是，MapFragment 错误仍然存在。
我已经根据@Imtiyaz Khalani 的回答更改了代码。新代码是这样的：
private void initilizeMap() {
if (mMap == null) {
//googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (mMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
但它给出了错误：The method getSupportFragmentManager() is undefined for the type MainActivity
