我尝试运行这些代码，但它会抛出错误：
HttpTransport无法解析为某种类型; NetHttpTransport不能 被解决为一种类型; OAuthHmacSigner无法解析为某种类型; OAuthHmacSigner无法解析为某种类型; OAuthGetTemporaryyToken无法解析为某种类型; OAuthGetTemporaryToken无法解析为某个类型; OAuthCredentialsResponse无法解析为某种类型; OAuthAuthorizeTemporaryTokenUrl无法解析为某个类型; OAuthAuthorizeTemporaryTokenUrl无法解析为某个类型;类型 mismatch：无法从String转换为boolean; OAuthGetAccessToken 不能解决一个类型; OAuthGetAccessToken无法解析 一种类型; OAuthCredentialsResponse无法解析为某种类型; OAuthParameters无法解析为某个类型; OAuthParameters不能 被解决为一种类型; HttpRequestFactory无法解析为 类型; GenericUrl无法解析为某种类型; GenericUrl不能 解决了一个类型; HttpRequest无法解析为某种类型; HttpResponse无法解析为某种类型;
我把代码放在这里：

}
And I already put all google jar.files to the build path in Eclipse.
Thank you for your help~~
