Question

I resolved this issue myself. It turns out that the activation framework requires some libraries that aren’t native to android, myjava.awt.datatransfer, org.apache.harmony.awt.*, and org.apache.harmony.misc. Once i added those libraries everything worked fine.

I’m trying to use the gdata java
client library on android and have
managed a decent hack to get it
working. However because the jar for
gdata had some package discrepancies
with android I had to import the
source into my project. This source
is dependent on the JavaMail API and
the JavaBeans Activation Framework as
specified here.

My issue is that the JavaMail jar
throws a class definition not found
when seeking a class which is in the
Activation Framework jar. A stack
trace is listed below. I am working
in Eclipse and have both jars in a lib
folder and added to my build path.
I’m not very experienced dealing with
jars in a situation like this so any
help or insight would be appreciated.
