Recover attactments with JavaMail in Android

^^ javi ^^Dec 27 2011 — edited Dec 31 2011
Hello,

I used Oracle JavaMail 1.4.4 + Oracle JAF 1.1.1 and additional.jar (javax.awt dependencies replacement) from [url http://code.google.com/p/javamail-android/] javamail-android

Me neither sounds good, but the only way I found to make it work, for the time being sent without problems.

But I have a problem retrieving attachments, and that is the code that I used before, now is not Mutipart instance.

This is the code:
SubjectTerm term = new SubjectTerm("[aNAME]");
						messages = inbox.search(term);
						      
						messages = ufolder.getMessagesByUID(1, UIDFolder.LASTUID);

				        // FetchProfile
				        FetchProfile fp = new FetchProfile();
				        fp.add(FetchProfile.Item.ENVELOPE);
				        fp.add(FetchProfile.Item.FLAGS);
				        fp.add("X-Mailer");
				        inbox.fetch(messages, fp);
						
						for (int n = 0; n < messages.length; n++) 
						{
							message = messages[n];
							uid = ufolder.getUID(message);
								
								messagecontentObject = message.getContent();
								
									if (messagecontentObject instanceof Multipart)
									{
When it comes to:
messagecontentObject = message.getContent();

if (messagecontentObject instanceof Multipart)
this is null (messagecontentObject) therefore can not go inside the if statement

This a debug trace:
