Android谷歌地圖碎片崩潰

我在Google應用中嵌入了Google地圖V2，就像谷歌教程中說的那樣。Android谷歌地圖碎片崩潰

切換到地圖片段時，出現以下錯誤。

您是否在您的項目的'AndroidManifest.xml'中包含了'de.arvidg.exampleactionbartabs.StartActivity'活動？ – 2013-03-08 11:59:28

java.lang.ClassNotFoundException：mainfest中的de.arvidg.exampleactionbartabs.StartActivity？ – DjHacktorReborn 2013-03-08 12:00:15

您的'MapFrag'不是一個活動，請嘗試從您的清單中刪除它。 – 2013-03-08 12:05:29

變化

android:name="com.google.android.gms.maps.MapFragment"/> 到

android:name="com.google.android.gms.maps.SupportMapFragment"/>在activity_main.xml中

，改變

public class MainActivity extends Activity

到 public class MainActivity extends FragmentActivity在MainActivity.java

這兩種修復爲我工作。
