Google Play services resources were not found.

今天更新了sdk到 4.3後, 發生了以上問題.
導致map api key v2失效,地圖無法顯示.出現白畫面.


查了老半天,終於發現解決方法:
<fragment
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        class="com.google.android.gms.maps.MapFragment" />

修正成:
    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"        class="com.google.android.gms.maps.SupportMapFragment" />

2. Remove this line from the manifest file:

<uses-library android:name="com.google.android.maps" />

This is Google Maps API V1 permission and shouldn't be use in API V2.
Take a look at this blog post and make sure are doing everything correctly:

3. 確定api key正確, 使用 registering the API key using the API Console,因debug.keystore 與正式release key是不同的.

4. 確定相關權限有開:
    <permission
        android:name="com.mark.taipeimrt.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="com.xxx.permission.MAPS_RECEIVE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

5.於sdk manager中,重新安裝 google play service,(先移除在安裝. ),記得要進去sdk manager  的tool-option中先clear cache.

6.刪除google-play-services_lib專案於eclipse(但不要選delete於硬碟中),重新再匯入一次google-play-services_lib專案.並clean project.

7.於測試機中移除app ,不可只是re-install.

8.確定wifi 與gps開啟.

9.clean all project and run.

以上步驟後,我的app中的地圖就可顯示了.

後記: ps: 最後發現沒有wifi/3g 連線時,就會出現上列訊息.
所以第一次run時,沒網路連線,就會顯示白畫面,會讓開發者以為是google play service有問題,但其實是沒網路連線.只要第一次成功顯示地圖後,就會快取下來,下次就不會白畫面.

ps注意:android 4.4 sdk更新之後, google play service就有分新版跟舊版2.x兩種,
如要用新版就要用上述方式.
但不想改動code,就要import  google play service for 2.x版本.
