无法使用移动SDK从android与Amazon SimpleDB对话

我正在关注他们随android SDK发布的amazon示例。我在我的应用程序中做了几乎完全相同的事情，但我得到了以下例外：

I/SSLSocketFactory(  967): Using factory org.apache.harmony.xnet.provider.jsse.OpenSSLSocketFactoryImpl@40062b40
I/SSLSocketFactory(  967): Using factory org.apache.harmony.xnet.provider.jsse.OpenSSLSocketFactoryImpl@40062b40
W/HttpClient(  967): Unable to execute HTTP request: sdb.us-west-1.amazonaws.com
I/SSLSocketFactory(  967): Using factory org.apache.harmony.xnet.provider.jsse.OpenSSLSocketFactoryImpl@40062b40
W/HttpClient(  967): Unable to execute HTTP request: sdb.us-west-1.amazonaws.com
I/SSLSocketFactory(  967): Using factory org.apache.harmony.xnet.provider.jsse.OpenSSLSocketFactoryImpl@40062b40

E/Guild::createMessageItem: (  967): java.net.UnknownHostException: sdb.us-west-1.amazonaws.com

这是我的要求：

I/com.amazonaws.request(  967): Sending Request: POST https://sdb.us-west-1.amazonaws.com / Parameters: (Attribute.3.Value: t9, Attribute.4.Name: created_by, SignatureMethod: asdedd, Attribute.5.Value: 2011-03-22 20:51:20, AWSAccessKeyId:<acccessid>, Attribute.1.Name: message_id, Attribute.3.Name: description, Timestamp: 2011-03-23T00:51:21.170Z, Signature: <securitycode>, Attribute.6.Name: modified, Attribute.2.Name: title, Attribute.2.Value: t3, Action: PutAttributes, ItemName: x1300841480654, DomainName: messages, Attribute.1.Value: x1300841480654, Attribute.6.Value: 2011-03-22 20:51:20, Version: 2009-04-15, SignatureVersion: 2, Attribute.5.Name: created, Attribute.4.Value: x@yahoo.com, )

有什么建议吗？

我找到了。这是我在AndroidManifest.xml文件中缺少的：

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