Forwarding ranges of ports to the Android emulator

 Hi! I'm working on a C++ library which uses TCP to estabilish
communications with the LAN. I've been able to use it without problems
on a real device with Android, but I'm not able to use it on the
emulator. I suppose it is because the emulator doesn't have access to
my LAN.

I read the documentation, and, as far as I can understand, it is
necessary to forwards ports for incoming connections with the redir
command. Unfortunately my library uses many different ports randomly,
jumping from one to the other as threads are spawned. So, would it be
possible to forward entire ranges of ports instead of single ports?

Thanks for any advice!

 It's amazing that this is a problem for alot of people out there but
there doesn't seem to be a resolution.

I am experiencing the same trying to write a simple FTP app, as part
of a larger app.

I can connect to an FTP server and perform cwd etc but as soon as I do
anything that requires an inbound connection to transfer data (list)
then it fails and i get an unexpted disconnect from the server.  very

Have you managed to work this one out yet?

Can anyone out there help!?

 Unfortunately no. No news. I'm still not able to work with
applications which uses extensively the network with the emulator. I
think this is really a limitation.

2. Question about Opengl ES2.0 in 2.3 SDK

Hi, I'm developing some application using Opengl ES2.0, especially
shader language.

Before 2.3 released, only RGB format is available to input to Opengl

So it is definitely needed for converting preview (YV12) to RGB before
main function.

However fortunately from 2.3 SDK, there is new features as below:

Adds support for YV12 pixel format

But I don't know how to use new feature. there is no reference.

I need some guide code or let me know hot to use it.
