Question

我正在尝试在Android模拟器上运行Android Hello Map View教程应用。显示Google地图视图，但图块为空白。

根据以下错误判断（取自LogCat），该应用无法连接到互联网。模拟器上的Web浏览器连接没有问题。我还仔细检查了API密钥。

我在Windows XP SP3上使用来自Eclipse Galileo的1.5 Google API SDK，位于公司防火墙后面。

我尝试了两种方法来添加代理信息：

将-http-proxy http://www.foo.co.uk:80添加到调试配置中目标页面中的其他仿真器命令行选项。
删除1.中的设置并在主页＆gt;处添加代理信息菜单＆gt;设置＆gt;无线控制＆gt;移动网络＆gt;接入点名称。

似乎都没有帮助。

还有其他想法吗？我应该在应用程序中添加代理信息吗？如果是这样，怎么样？

修订：已将清单申请元素添加了互联网权限：

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

Answer 1

做了同样的事情，把“”移到了“”之上

<小时/>

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

<application android:icon="@drawable/icon" android:label="@string/app_name">
 <uses-library android:name="com.google.android.maps" />

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

</application>

Answer 2

您是否在清单文件中设置了Internet权限？

我相信你一定要检查：）

Answer 3

看起来这是一个错误： Issue 3764: Google Maps fails via mandatory web proxy。

Answer 4

对我来说，我将权限放在Manifest文件中的错误位置。它不应该在应用程序节点内，而应该与应用程序节点处于同一级别。
