在Android中解析javamail消息以获取正文部分

我试图在android中使用IMAP检索电子邮件。我设法从收件箱文件夹中检索邮件，但是在解析它们时遇到困难，特别是收到邮件的正文部分（我打算在我的应用中进一步使用）。在Android中解析javamail消息以获取正文部分

我需要的是一个函数，它接收一条消息并返回明文正文部分（如果可能，不考虑附件）。

private String getbody(Message message) {   

    try { 
     Object m=message.getContent(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
      e.printStackTrace(); 
    } catch (MessagingException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

    return "abc";    // THE BODY PART TO RETURN

}

我有进口的activation.jar文件。但是使用message.getcontent();给我错误：
