有關meta標籤

Question

我想實現簡單的谷歌谷歌MapV2誤差圖譜例如我搜索有關，但沒有明確的解決方案 清單：

package="com.syntel.mapexample" 
android:versionCode="1"

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="AIzaSyBllmHwXofzx3N6YpCKmkMXh7rfc4lSL_Q" /> 
</application> 

    </manifest> 

XML：

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

    </RelativeLayout>

Answer 1

異常喜歡說：

You must have the following declaration within the <application> element: 
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

添加它低於或高於谷歌地圖API密鑰

Answer 2

添加谷歌Play服務版本，您的應用程序的清單

編輯您的應用程序的AndroidManifest.xml文件，並添加 在元素之後聲明。這嵌入了該應用程序編譯的Google Play服務版本 。

您需要添加<meta-data>下<application>代碼到你的AndroidManifest.xml

....<application> 
<meta-data android:name="com.google.android.gms.version" 
android:value="@integer/google_play_services_version" /> 
</application> 

這是因爲latest google play services requires a version name, which is to be mentioned using <meta-data .. /> inside AndroidManifest.xml
