android-developers - Android & Corba

Hi all !
I just have a quick question. Is it possible to use CORBA in an
Android app ? Because I learned how to use it at school, and I was
wondering if I could use it with Android to create multi-users
applications/games without using a server...
I searched Google and the Groups, but I got nothing...
Thanks for your help and your time :)

I am hoping that you learned it 15 years ago, back when it was popular.
Many mobile carriers do not give phones public IP addresses, using NAT
and firewalls. It is highly unlikely that you will be able to
establish direct peer-to-peer connections between phones over 3G. For
devices working on a private LAN, it is far more realistic.

But, if you can find an open source CORBA library for Java and can
port it to run on Android (may take no effort or a lot), you are
welcome to experiment with it.

OK...
So, if I can't use CORBA, what is the best way to program multi-users
apps ? I'm insisting on the fact that it needs to run without a server
access, because I'm a student, and I can't afford to buy or rent a
dedicated server...

Then don't "buy or rent a dedicated server".
Rent a VPS (e.g., Slicehost). Write your server piece on Google App
Engine. Use XMPP and public XMPP servers (GTalk, etc.). See if anyone
is using JXTA on Android and has a NAT-traversing proxy you can use.
I am sure there are many other solutions.

An ORB ships with JavaJava RMI/IIOP should also work, as would RMI/JRMP, which is probably easier
to write.

The best use for CORBA in the Android context is this: use your
familiarity with CORBA as an example of what an SOA architecture is,
then use your understanding of SOA to understand Android Intents,
which have often been compared with SOA. Manning Press's "Unlocking
Android", for example, says,
"In many ways the Android architecture is similar to larger Service-
Oriented Architecture (SOA) approaches in that each Activity makes a
type of Intent call to
get something done, without knowing exactly what the receiver of the
Intent may be."
Actually doing a build of CORBA code on the Android platform would be
incredibly wasteful. Surely you have better uses for your time.

Google app engine is affordable even to a student without any funds -
and if your apps needs more than free account, you habe probably soo
much traffic
and app sales that you can actually afford a dedicated server

CORBA no. However, you can do client server apps using ICE from ZeroC
(http://www.zeroc.com/labs/android/index.html). I did CORBA
programming several years ago and stumbled onto ICE a year or so ago.
I've not done anything other than simple stuff, but from what I've
seen it is fairly easy to use...especially compared to CORBA.
