I'm trying to run the Android Hello Map View tutorial app on the Android emulator. The Google Map view displays, but the tiles are blank.

Judging by the errors below (taken from LogCat) the app is unable to connect to the internet. The web browser on the emulator connects without problems. I've also double-checked the API key.

I'm using the 1.5 Google APIs SDK, from Eclipse Galileo, on Windows XP SP3, behind a corporate firewall.

I've tried two methods to add proxy information:

  1. Add -http-proxy http://www.foo.co.uk:80 to Additional Emulator Command Line Options in the Target Page in Debug Configurations.

  2. Remove settings in 1. and add proxy information at Home > Menu > Settings > Wireless Controls > Mobile Networks > Access Point Names.

Neither seems to help.

Any other ideas? Should I be adding proxy information within the app? If so, how?

AMENDMENT: internet permission has been added to the manifest application element: 

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

做了同样的事情，把“”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>

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

您是否在清单文件中设置互联网权限？

我相信你一定只是检查过:)

看起来这是一个错误：问题 3764：谷歌地图通过强制网络代理失败。
