Question

我想在我的应用中显示一个简单的Google地图。我正在学习本教程http://www.vogella.com/tutorials/AndroidGoogleMaps/article.html，但我得到一个异常 - 膨胀类片段。所以我有以下XML代码。

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 tools:context=".DrawMap" >

    <fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

java文件：

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.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

import android.app.Activity;
import android.os.Bundle;


public class DrawMap extends Activity  
{
static final LatLng HAMBURG = new LatLng(53.558, 9.927);
static final LatLng KIEL = new LatLng(53.551, 9.993);
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_draw_map);

    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

    Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
            .title("Hamburg"));
        Marker kiel = map.addMarker(new MarkerOptions()
            .position(KIEL)
            .title("Kiel")
            .snippet("Kiel is cool")
            .icon(BitmapDescriptorFactory
                .fromResource(R.drawable.ic_launcher)));

        // Move the camera instantly to hamburg with a zoom of 15.
        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        // Zoom in, animating the camera.
        map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
}


}

我不明白我做错了什么。我正在逐步完成本教程我仍然得到膨胀类片段异常。

manifest.xml文件代码：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="musat.modum.mobilephone.application"
android:versionCode="8"

</uses-feature>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:theme="@style/AppTheme" >           

    <activity
        android:name="com.vogella.android.locationapi.maps.DrawMap"
        android:label="@string/title_activity_draw_map" >
    </activity>

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyDtZreW9OZf2aIe4NKj3SJRGqBrkjHQ9E8" />
</application>

无法在应用程序中显示Google地图（膨胀类片段 - 例外）
