I'm trying to write a simple app to access my mail inbox, check if
there is any new mail and open that meail. the source code for POP3
mail is from http://forums.sun.com/thread.jspa?threadID=5267916, then
add mail.jar, activation.jar to my project. I managed to compile and
run the app on Google G1, but it crashed and report as below:

awt/datatransfer/Transferable;'

i tried to get java.awt.datatransfer package from rt.jar of jre6, but
it failed to compile, and reported
[2010-01-05 17:02:53 - MailJar]
trouble processing "java/awt/Image.class":
[2010-01-05 17:02:53 - MailJar]
Attempt to include a core VM class in something other than a core
library.
It is likely that you have attempted to include the core library from
a desktop
virtual machine into an application, which will most assuredly not
work. If
you really intend to build a core library -- which is only appropriate
as
part of creating a full virtual machine binary, as opposed to
compiling an
application -- then use the "--core-library" option to suppress this
error
message. If you go ahead and use "--core-library" but are in fact
building
an application, then please be aware that your build will still fail
at some
point; you will simply be denied the pleasure of reading this helpful
error
message.
[2010-01-05 17:02:53 - MailJar] 1 error; aborting
[2010-01-05 17:02:53 - MailJar] Conversion to Dalvik format failed
with error 1
Then i read from somewhere, that java.awt.datatransfer should be
downloaded from Apache Harmony SVN, so i tried to look for it there,
but no hope -.-"
can any1 help me to solve this? thanks in advance
