android - 使用 AccountManager token 的 IMAP/SMTP 身份验证

Question

我正在尝试使用从 Android 的 AccountManager 接收到的 token 而不是使用用户名和密码来实现一个简单的 IMAP/SMTP gmail 客户端。我正在尝试使用“邮件”作为 getAuthToken() 的 authTokenType 参数。

Google 提供了这个带有 oauth2 的 SMTP/IMAP 示例 http://code.google.com/p/google-mail-oauth2-tools/source/browse/#svn%2Ftrunk%2Fjava%2Fcom%2Fgoogle%2Fcode%2Fsamples%2Foauth2 http://code.google.com/p/google-mail-oauth2-tools/wiki/JavaSampleCode

但它是针对 java 的。在我的 Android 项目中使用它时缺少一些导入(关于 SASL)。为了解决这些问题，我使用了这个库 http://code.google.com/p/asmack/

示例可以编译，但我发现运行时有问题

似乎 asmack 使用 org.apache.harmony.javax.security.* 而不是 javax.security.*

有人遇到过这个问题吗？谷歌似乎没有在他们的示例中考虑这种可能性，但我认为这应该是用户的共同特征。

谢谢。

为了在 JavaMail 中使用 ASMACK Authenticator，我创建了一个补丁版本的库:http://www.mannaz.at/codebase/imap-ssl-mail-android/

它基于http://code.google.com/p/javamail-android/但支持 ASMACK SASSSL 验证器。

JAR 文件中缺少此类。只需将它添加到您的源代码中:

package com.falott.ingresss.util;
public class Log {
    public static boolean loggingEnabled(){
       return false;
    }
}
