如何解決Android中的「無法膨脹」運行時錯誤？

Question

我的應用應該打開地圖。我已經包含了播放服務，實現了片段，並盡我所能做到了！不過，我在運行時遇到了「無法充氣」的錯誤。

我把我的清單文件，佈局文件和logcat錯誤。

清單

佈局

android:layout_width="fill_parent" 
android:layout_height="fill_parent" 

tools:context="xyz.xyz.Home" > 


     <fragment 
      android:id="@+id/mapView" 
      android:name="com.google.android.gms.maps.MapFragment" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_alignParentBottom="true" 
      android:layout_alignParentLeft="true" 
      android:layout_below="@+id/acceleration" 
      android:layout_marginTop="20dp" 
      android:apiKey="GoogleAPIKEY//I Added a Key, I just do not feel comfortable to display it" 
      android:clickable="true" 
      android:enabled="true" /> 

</RelativeLayout> 

logcat的

有更多，但這些看起來很重要。另外它所說的添加爲元數據已被添加，它仍然會產生一個異常。

您是否有Google Play服務圖書館在您的Android SDK？如果沒有，去檢查http://developer.android.com/google/play-services/setup.html。 如果你想離線下載谷歌播放服務，去http://venomvendor.blogspot.com/2012/03/android-sdk-extras-by-google-inc.html。
