我正在构建一个使用 Gmail 备份一些数据的应用程序。我使用 XOAUTH 连接到 Gmail 并获得了 token 和密码。但是我无法连接到 Gmail 的 IMAP 服务。我按照 http://code.google.com/p/google-mail-xoauth-tools/wiki/JavaSampleCode 中的示例进行操作:

Properties props = new Properties();
props.put("mail.imaps.sasl.enable", "true");
props.put("mail.imaps.sasl.mechanisms", "XOAUTH");
props.put(OAUTH_TOKEN_PROP, oauthToken);
props.put(OAUTH_TOKEN_SECRET_PROP, oauthTokenSecret);
props.put(CONSUMER_KEY_PROP, Const.CONSUMER_KEY);
props.put(CONSUMER_SECRET_PROP, Const.CONSUMER_SECRET);
Session session = Session.getInstance(props);
session.setDebug(debug);

final URLName unusedUrlName = null;
IMAPSSLStore store = new IMAPSSLStore(session, unusedUrlName);
final String emptyPassword = "";
store.connect(host, port, userEmail, emptyPassword);
return store;

运行时报如下异常。

我用的是SUN的javamail。有人愿意帮助我吗?

最佳答案

我遇到了同样的问题。

启用调试后 (session.setDebug(true)) 我注意到我收到了 ClassNotFoundException在显示临时系统错误之前。

查看 JavaMail 源代码,这似乎是因为它正在尝试加载 com.sun.mail.imap.protocol.IMAPSaslAuthenticator,它依赖于非 android java 资源。

javax.security.sasl.*
