[PJUG Javamail] Android VM

[Elias Volanakis]

You can browse the available packages here:

Obviously swing and awt is not available. If you have something that
is algorithmic in nature it could be straightforward. I ported an
mp3-tag-reader to android this way (pretty much java.lang, java.io,
java.collections only).

If you have a whole app you will have to rethink the UI and the flows.
First a non-phone app will likely assume a large UI and will not be
optimized for touch. Also Android apps have a lifecycle that is
different from Java apps. They consist of several Activities that have
a strict lifecycle (think: App as a state machine, where each state is
an Activity. activities reminded me a bit of applets). This is a good
explanation:

Hope this helps?
