Google Maps V2在Android 2.2上显示空白屏幕

Question

我尝试了关于Android Maps V2快速入门的教程 但是当我运行应用程序时,会显示一个空白的地图屏幕.我的手机使用Android 2.2.1.

这是logcat中显示的内容:

编辑:这是manifest.xml文件:

我终于发现了问题所在.我选错了调试密钥库.我正在使用ubuntu机器.由于我以root身份打开eclipse,eclipse中的默认密钥库位于我的根文件夹(/root/.android/.android/debug.keystore),而我正在使用我的用户文件夹中的debug keystore创建api密钥.我在根文件夹中使用调试密钥库创建了一个新的api密钥,它现在可以正常工作了.
