Since last Android versions you're not supposed to add libraries from the build path, but just copy&paste them into libs folder.

Remove external jars (activation.jar, additional.jar and mail.jar) from your Build path, and add them to libs folder (you may create the folder if it doesn't exist).

I had done that, but in that case there was a red exclamation mark over the project name, so I added them here and that error was gone, just so this error can show up

Could you post the error showed on problems tab going the libs folder way?
