Subject: Android usb network
Hi All,

I'm looking a good way to bring Android device in intranet using USB,
what I want is to connect my Android tablet to a PC in network and
then work on Tablet as a PC.

 In that way I can take print from a network printer also take
adventage of better network connection within my network.

Just to give a idea, I'm developing a application which runs in
Intranet and few user will have Tablet as interface and few user will
have deskstop as interface. Tablet user should be able to work just
like a desktop user but with rich user interface so that user can just
work with there fingers insted of keyboard/mouce.

please point me to right direction,links. as long as possible  I do
not wants to create any dependancy to third party application for this
purpose.

Are you developing this device or using an existing device?

You should look at the EthernetStateTracker class.  You need to modify the
networkattributes config.xml property to instantiate type 9 and add type 9
to the radioattributes config entry.  You'll need to add an ethernet dhcp
agent to init.rc.  You'll need to add a usb-ethernet driver to your kernel
image.

These things I think are available in the TOT of AOSP, but may not be
available on older devices.

It may be simpler to have an internet-visible gateway into your intranet
app, then you could access it worldwide and wouldn't need to do this
busywork of usb-ethernet.  Alternatively add a wifi access point to your
lan and connect your tablet that way.  Wires are passe.

Thanks Robert,
- I'm developing a application on Android 4.0 ideally this will work
on any android supported device, as of now we do not wants to put any
hardware restriction but if require we can have hardware dependancy.
I mean we thought of running application on any android device but if
require we put restriction saying this can work on device with this
configurations.

The application is a very simple user registration application

The requirement what we have is, our users do not wants a wifi network
they wants a physicial connection to device for network (for security
reason) we will put tablet at multiple location in my clients network
with physical connection. If we really need then we can put multiple
PC as well for connecting device to network, just need network in my
Tablet without wifi and Tablet should be able to charge at same time.

The device we are going to use will be latest one.

where can i found EthernetStateTracker class ?

I think here is the answer what I'm looking but this solution is given
for connecting to device's network and I'm looking reverse

http://support.google.com/mobile/bin/answer.py?hl=en&answer=182134

Under USB Tethering with Windows XP

I will try this and see if device can also use PC's network.

I certainly don't see its merit in terms of power consumption and
complexity.

Why don't you just use the computer then?

My suggestion is to use a tablet that have a physical Ethernet
connection.
Some tablet have ethernet port when you use the dock. Isn't this a
better solution than a tablet tethered to a computer USB port?

Otherwise, I wonder how it is possible for USB client (tablet) to
access the computer's network... via USB..
Even if it is feasible, sounds like it needs complicated/customized
applications on both PC and tablet to do it.

sounds better needs to find tablet with physical Ethernet connection.

About wired tablet, The merit what we see is a user can work offline,
tablet will be handy and environment we are trying to build is a
single portable solution without having complexity of data
synchronization process for user (offcource as application developer
complexity remain with us)
An user work in offline mode, collect data from market wherever, come
to office connect his device to Lan and visualize his data with server
application, and process his data. isn't simple ? instead of working
with computer when he is in office and with tablet when outside. also
it take just half an hour to learn mobile functionality and may take
much time to learn computer (and users of our application will not
need computer background)

An WiFi do the job but it's not secure, (imagine if someone shared
network key) I mean our client does not want a WiFi and that's reason
we are looking alternative.

How about use a secure connection (https)?  If it's good enough for banks
and e-commerce, perhaps it's good enough for your use?

WPA2 EAP might also work -- no shared passwords, and tablets with pre-installed
keys and certificates should take care of security issues at the cost of some
infrastructure complexity.

Subject: Re: Android usb network
as per my understanding https or any other security method like
certificates works on internet application, and in our case we do not
have any application on internet it's in intranet.
as such there is no need of having application on internet as it's
more related to back office operation, and IT operation people never
allow to give access over internet for a internal server.

And about pre-installed keys, I think this may work but not easy to
conveince IT infrastructure people, and personally if I'm at IT
infrastructure side then I will also not allow as my entire network
can be hacked with just one network key, with wired connection some
have to connect phycially.
And building security infrastructure for using tablet is out of scope.

I see on some post that few device are comming with dock for wired
connection and also there are some usb ethernet adapter available, I
don't know if it's possible to connect using such adapter.

I don't know much about networking but a normal usb dongle can do
networking then how come it's not easy to do same with an device

EAP works at the network level, your application(s) don't need to
to know about it.

There is no 'one network key'. Each tablet would have it's own separate
key and certificate, and can easily be revoked if the tablet is lost
or stolen.

If you want to require physical access, shield the whole room :)
Only people inside will be able to connect. Put a couple of
guards at the door, and you will be air-tight :)

If it not supported by Android natively, you either need to find some
manufacturer
that offers this in their custom firmware, or develop one yourself. This may or
may not be cheaper that using standard infrastructure (or shielding :))

Do post here if you find something that works.

Thanks Nikolay, The point which is I will not able to convince is use
of WiFI in there LAN, I agree that tablet can have pre installed keys
and it is fully secure but client does not wants to open private
network door with WiFi access.

May be I''m over looking the problem, Does any one using devices in a
private network? and how your network team manage security.

Other solution I'm thinking is having a WiFi router not in private
network, Device will have network with this router and then create a
VPN access in device and with this VPN enter into private network. I
mean the same method we use for work at home. I think VPN connection
in device is feasible, The drawback of this would be low  performance.
But at least I will have something working.

if someone highlight any link or guideline that would be really
helpful or any other work around.
