Android Hello Map 查看模拟器上的问题

Question

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

根据以下错误（取自 LogCat）判断，该应用程序无法连接到互联网。模拟器上的 Web 浏览器可以正常连接。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：

1. Add -http-proxy http://www .foo.co.uk:80 到调试配置中目标页面中的其他模拟器命令行选项。

2. 删除1.中的设置并在首页>添加代理信息菜单>设置>无线控制>移动网络>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，怎么办？

修正案：互联网权限已添加到清单应用程序元素中：

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

Answer 1

做了同样的事情，将“”移到“上面”

<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互联网权限？

我相信你一定刚刚检查过:)

Answer 3

看起来这是一个错误：问题 3764：Google 地图通过强制网络失败代理。

Answer 4

对我来说，我将权限放在清单文件中的错误位置。它不应该位于应用程序节点内，而应该与应用程序节点处于同一级别。
