在Android項目中導入Google-Play-Services會刪除R文件

Question

嘗試使用google maps v2作爲this link建議的應用程序時，我介紹了獲取密鑰然後跟隨procedure導入Google Play服務的過程。但當我在我的項目中導入庫時，我發現R文件丟失。任何人都可以建議如何解決這個錯誤。

編輯

代碼和它的日誌貓。

public class Maptest extends FragmentActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.maplayout); 
    } 
} 

XML文件：

<?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" 
    class="com.google.android.gms.maps.MapFragment"/> 

，然後允許在清單文件中給出

<uses-permission android:name="android.permission.VIBRATE"/> 
<uses-permission android:name="android.permission.CAMERA"/> 
<uses-permission android:name="android.permission.WAKE_LOCK"/> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.INTERNET"/> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

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

Answer 1

重新啓動項目，運行全新的重建項目。如果問題仍然存在，請嘗試檢查其他文件中是否存在其他錯誤。如果問題仍然存在，請嘗試編輯並保存de AndroidManifest.xml。

Answer 2

問題可能是這一個。

com.google.android.gms.maps.SupportMapFragment.onInflate(Unknown Source) 02-20 10:30:16.093: E/AndroidRuntime(21076): 
at android.support.v4.app.FragmentActivity.onCreateView(FragmentActivity.java:271) 

因爲我認爲你已經使用過。

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

它應該是。

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/map" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
class="com.google.android.gms.maps.SupportMapFragment"/> 

Google Play服務庫使用SupportMapFragment而不是MapFragment。你也可以在他們的谷歌地圖演示中看到他們使用了SupportMapFragment。
