Is Android able to use 2 networks interfaces at the same time ?

[André Oriani]

[moving from android-framework because that group is deprecated]

Every time my application need to establish a data connection it must
always do it using the carrier network.
So suppose Wifi is enabled . User shall be able to use browser and my
application at the same time. Browser might use WIFI, but my
application shall always use the carrier network (GRPS,EDGE, ...).

Is there any ways to tell Android it should always use a certain
network interface for my application?

No, we currently do not have support for that. There is some special
case code for this to handle MMS when Wifi is on, but no general
mechanism for doing this.

Mike, is this code for MMS on platform/packages/apps/Mms.git ? If so I
can do the same thing

thanks,
André

From reading this discussion it's not clear to me what you're trying
to contribute to the Android Open-Source Project, if anything. If
you're developing an application that's not going to be contributed
(either because you're toying around, or as part of your job for an
unnamed company), you'll find that the android-porting list is
actually a more list for such discussion.

Thanks,

okay JBQ-
moving it as you wished !

[Mike Lockwood]

No, the code to bring up the MMS connection is in various parts of the
framework telephony stack, like GsmDataConnectionTracker.java and
ConnectivityService.java. We have some plans for making this more
general, but I'm not sure if it will be accessible via the public
application API.

As already mentioned the current platform does not support two radio
interfaces at the same time.

For being able to support this you have to change the framework/
platform code. If you want to support this functionality correctly on
SDK level you have have to implement an extension to support

- select a radio interface
- selection criteria (speed/bandwitdh, costs, signal strength, ...)

This can become very complex if you try to add some more intelligence
to this. Be also aware that the battery is draining much faster.

And what about android.net.ConnectivityManager.requestRouteToHost(int,
int) ? Does it works? It's what MMS calls before any HTTP POST.

So, what it is supposed to happen if phone is Wlan attached and user
sends a MMS?

create a socket using Mobile radio interface since only that network
can provide MMS service

[André Oriani]

I see now. MMS really got special treatment. Besides, it has its own
APN. I shall stop bothering you
