Android Java Client

[Madhan]

Hello,

I'm looking to create an Android client for the BBB. Nothing fancy.
Just a simple client that will allow a user to join a meeting by
entering credentials, listen in and share his/her microphone. Not
looking to build any video capability.

Flash is not an option for the client as the target is Android 2.1
upwards.

For audio streaming I'm looking to use Flazr to communicate with BBB's
underlying Red5 server.
However my problem is logging in a user into a meeting before he/she
can start streaming his/her microphone.

I notice that BBB uses actionscript to perform the actions of joining
a user into a meeting.
Not sure how to implement this in Java. Any suggestions on this would
be terribly helpful!

PS - I went through all the Android posts in here. Especially the ones
related to GSoC. Wasnt really able to find what I need.

You'll need to be able to do remote procedure calls, the way they're done with the flash.net.NetConnection class. Not sure if flazr implements this. The important methods is NetConnection.call(...)

Hi Madhan,

From what I understand about Flazr, it is a java client for the rtmp protocol, so there must be a connection class... I think that first do some testing like a POC... Another thing, did you already port flazr to android? I mean, for somewhere I saw that flazr has a lot of dependecies and it was a little difficult to use in android (I'm just asking)....

[Madhan]

Hey Thanks for the replies.

@Denis
I'm using a flash client to join a user and try understanding how
NetConnection is calling the remote function.
I'm not versed with ActionScript. So pardon any silly questions.

I see that in NetConnectionDelegate.as, NetConnection.connect(...) is
used to connect to the remote server using the uri of the Conference
room.
However once this is called, the entry point in the remote application
is in the participantJoined(...) function of ViewersSOService.as where
the user is joined into the conference. My question is where is the
mapping to the function participantJoined()? I'm probably missing
something obvious.


@Markos
I've not yet ported Flazr to Android. I've read mixed comments. I
contacted the developer of Flazr and he said its quite possible to
implement, as the dependencies have been reduced with the latest
version. So good luck to me :)
And, Flazr uses Netty Framework for making connections. Will have to
explore more on that once I figure out what parameters are needed by
the BBB server.

[Denis Zgonjanin]

participantJoined() is called by the server. ViewersSOService registers a Shared Object with the server, and from there the server makes a remote procedure call to participantsJoined() whenever a new user joins.

I would like to help with this..Back in time I applied for Gsoc for
building the Android Client. I do have experience with AS and Android
Programming.
So keep the discussion updated as you have some progress.

Out of curiosity, why your target is 2.1? Developing a client for 2.2
onwards would be much easier, there is both Flash Player 10.1 and AIR!

[Denis Zgonjanin]

I agree, if you do change your mind and want to develop for 2.2 and up, we have started work on a mobile client for Android written in ActionScript. The idea is to compile it to AIR and run as a native app.

You can find it here:

https://github.com/deniszgonjanin/bigbluebutton-mobile

The project is still very early on, so if anyone wants to join it and make major contributions now would be a good time.

@Denis, Andrea
Ah well I'm not an independent developer in this and the powers that
be need support for 2.1. So Java it is.
That said, will definitely check out the AIR app.

@Andrea
I'm currently looking at using an AMF library for making remote calls
from the java client to flash. Found BlazeDS, but apparently does not
work well with Android. Open AMF seems to be very poorly documented.
Any other library you are aware of that is known to work with Android?

[Daronco]

Hi all,

This is my first message here, so a brief introduction:
I'm part of a research/development group form a brazilian university
-- http://www.inf.ufrgs.br/prav (pt-br only, sorry). We are in the
early stages of a project that basically consists in creating a web
conferencing system (open source). So we are thinking about using bbb
(and developing over it).

One of the features we need in our system is a mobile client (Android
at first). So we are very interested in the bbb-mobile project, and
willing to help the development.

We are just starting to use and check how bbb works, so we will need
some time to ramp up. For now we are 2 guys working on this (among
other things)...

@Denis
What should we do to start the development? Should we contact you
directly? Or we keep posting to this group?
We have a group where you can contact us if you want to:
mc...@googlegroups.com

Thanks, regards
Leonardo Crauss Daronco

Welcome Daronco to the BigBlueButton-dev mailing list! You'll find
everyone here, including the core development team, very open to
having others pick up projects that contribute to BigBlueButton.

We recommend you keep posting to this group as there are other android
developers that could help out. If they see you as investing your
time and expertise to build a good android client, you'll stand an
excellent chance of attracting them to help out and accelerate the
project.

Don't worry about the ramp-up time, we've found that persistence pays
off with building BigBlueButton (some of us have been working on it
for over three years now).

Hope you are successful in getting your project going. It's
inevitable that your going to see Android and iOS clients for
BigBlueButton, it's just a matter of who is persistent enough to build
them.

Regards,... Fred

Just an update for anybody who might find it helpful. It was possible
to port bbb to Android using Java. I used a paid library called Smaxe
to mimic the flash NetConnection, NetStream calls. Very lightweight
and pretty well documented.
Thanks for the tips along the way.

Do you mean that you have this working?

Jeremy Thomerson

[Madhan]

Yes. A simple android client without flash that logs you in to a
conference and streams audio, no video.

Hi Madhan,

We're glad you were able to make it work.

We are very interested (if possible and doesn't violate your contract)
if you could share your experiences on developing the client.

What's possible and What's not in Android?

What worked? What did not? What changes in BBB could have made your
work easier? What in BBB made your work simpler? etc.

Thanks.

@Richard
Well, my requirement was to make the app for 2.1. So I didnt have
flash to work with.
Most of my time was spent trying to find a java library to mimic the
flash remote procedure calls.
So an app for 2.2 and above should be easier.
That said, a little more documentation on what the exact remote
procedure calls for logging in, begin streaming etc would have been
helpful. Right now its required to dig in the code to figure that out.
