 Tony Liao,

To make sure you get enough responses are you open to a talk either  by
gtalk voice or sklype as well?

1. META-INF from imported jars

I've been playing around with a simple IMAP client for Android using  
the Sun javamail API. After overcoming java.awt.datatransfer  
dependency limitations of the activation.jar (as described by 
http://davanum.wordpress.com/2007/12/22/android-send-email-via-gmail-actually-via-smtp/)
 
, I discovered that I can only derive an InputStream from a  
MimeMessage contents. Strangely, nearly identical code works correctly  
as a normal java application.

After a deep dive into the javamail.jar and activation.jar source  
code, I discovered the problem. The android application cannot find  
the META-INF/mailcap file that exists in javamail.jar. I've traced the  
problem as far as the call to ClassLoader.getResources("META-INF/ 
mailcap") in SecuritySupport.getResources() of activation.jar.  
Unfortunately, the Android SDK does not provide the source for  
ClassLoader and I cannot inspect the operation. I can only see that it  
returns an empty enumeration.

While the above case may be limited in scope (although I imagine  
Android users will want an IMAP client), it may be endemic of a larger  
problem. Namely,

Does the Android SDK import files included in the META-INF directories  
of imported jar files?

Thanks,

-Will

2. Android Tutorial by Dan Morril

Have tried Android Tutorial by Dan Morril on YouTube, tested on
Android SDK m5-RC15.

Those bunch of code seems not working on the new release, have not
tried the older release, do not have a copy of it.

Have anyone here get the code working before? Would very much
appreciate to hear about it.
