Android的地图问题

我试图让使用map.after做的不可见的所有编码图在output.only一个zoomin和zzomout按钮简单的应用程序是可见的Android的地图问题

下面

是清单文件

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.map1" 
android:versionCode="1"

     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 

    <meta-data android:name="com.google.android.maps.v2.API_KEY" 
     android:value="AIzaSyBoSLfTOWdAny2vrtwMx6lFTuWdoyANJlQ"/> 
</application> 
</manifest>

下面

是xml文件

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:map="http://schemas.android.com/apk/res-auto" 
android:id="@+id/the_map" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:name="com.google.android.gms.maps.MapFragment" 
map:cameraTilt="45" 
map:cameraZoom="14" 
/>

我在HTC 1X测试我的应用程序。

这里是logcat的

08-27 00:24:10.419: I/(3812): Loading GLESv1_CM implementation /system/lib//egl/libGLESv1_CM_tegra_impl 
08-27 00:24:12.284: I/Google Maps Android API(3812): Failed to contact Google servers. Another attempt will be made when connectivity is established. 
08-27 00:24:27.739: E/Google Maps Android API(3812): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

看看在logcat的，它应该给你一个错误。你能把它放在这里吗？ – jprofitt
