You are trying to use classes that the Android platform simply doesn't support (see the nice error message - in this case it's very informative). In your case "javax.naming" from JNDI which is a core class is not present, but regardless, not every java library runs or is supported on Android (not everything that runs in a "standalone application" which probably means desktop or server VM).
If you want to send email you might want to consider using an Intent and going through the mailer UI so the user knows what's happening, or if you want to do it programmatically it's purported that JavaMail works without any porting (to use commons-email you will have to port the parts Android doesn't support, that is, modify it to work with Android).
