Android和Javamail;更新JDK和ADT后，我得到验证错误？

Question

我一直在使用JavaMail工具以前在我的应用程序，这是我在这里找到： javamail-android

直到最近，一切运行良好。我只是将我的构建路径下的.jar文件添加为外部罐子。我最近更新到JRE7和ADT 17，现在我正在验证错误！这似乎围绕着javax.mail.Multipart，但我不确定如何解决此问题。事情我已经尝试：

1. 添加的jar LIB /，链接源文件夹
2. 从的lib /文件夹添加到罐子路径
3. 直接添加到构建路径
4. 加入Multipart.java源文件

我可以尽可能运行应用程序，成功验证凭据，加载IMAP文件夹和消息，但我现在无法获取消息的多部分内容。这是它似乎失败的地方，偶尔也会在首次启动图书馆时出现。下面是我的踪迹：

我唯一的想法是恢复到早期版本的JDK和ADT构建？ 需要帮助这个，任何意见将不胜感激！

编辑：

出于某种原因，在导入必要的JAR文件，mailcap中的设置值一扫而光。在阅读Multipart消息之前，我重新加载了设置，并且按预期工作。

MailcapCommandMap mc =（MailcapCommandMap）CommandMap.getDefaultCommandMap（）; mc.addMailcap（“text/html ;; x-java-content-handler = com.sun.mail.handlers.text_html”）; mc.addMailcap（“text/xml ;; x-java-content-handler = com.sun.mail.handlers.text_xml”）; mc.addMailcap（“text/plain ;; x-java-content-handler = com.sun.mail.handlers.text_plain”）; mc.addMailcap（“multipart/* ;; x-java-content-handler = com.sun.mail.handlers.multipart_mixed”）; mc.addMailcap（“message/rfc822 ;; x-java-content-handler = com.sun.mail.handlers.message_rfc822”）; CommandMap.setDefaultCommandMap（mc）;

假如因为最近这些SDK变化的同样的问题：

Dealing with Dependancies

什么工作对我来说是从构建路径中取出罐，重新添加它们，确保它们标记为出口。
