I’ve been using a javamail implementation previously in my applications, which i found here:
javamail-android
Until recently, everything worked fine. I simply added the .jar files as external jars under my build path. I recently updated to JRE7 and ADT 17, now i’m getting verify Errors! This seems to revolve around javax.mail.Multipart, but i am unsure how to fix this issue. Things I have tried:
- adding the jars to lib/, linking source folder
- adding jars to path from the lib/ folder
- adding directly to build path
- adding the Multipart.java source file
I can get as far as running the app, successfully verifying credentials, loading IMAP folders and messages, but i cannot get the Multipart content of the message now. This is where it seems to fail, and occasionally when first launching the library. below is the trace i have:

The only other idea i had was to revert to an earlier version of the JDK and the ADT build?
Need help on this one, any advice would be greatly appreciated!
EDIT:
For some reason while importing the necessary jar files, the mailcap settings get wiped out. I reloaded the settings before reading the Multipart message, and it works as expected.
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);
Had the same problem because of these recent SDK changes:
Dealing with Dependancies
What worked for me was removing the JARS from the build path, re-adding them and making sure they were marked as exported.
