I want to create an application that runs on Android and uses Raw Sockets. I see there isn't any raw socket support in the java.net.* or the android.net.* libraries. Are raw sockets possible on Android?

A:
Correct, raw sockets are not supported in any Java or Android libraries, in part because (I quote from here):
it is believed that such a package would degrade the current Java security model and may be difficult to implement in a non-operating system (OS) dependent fashion.
There are 3rd party libraries like RockSaw or JSocket, however these require compiling C or C++, so you are out of luck there.
Also, I believe you need root access to use raw sockets.
So, with all that, I would say technically it's possible, but not practical at this time.

You can use the Android NDK for C/C++ code. That doesn't help with the access restriction though.

I actually need Raw Sockets. The purpose of using Raw Sockets is so the packets can be manipulated. I want to write a PPPoE layer, which would require access to the raw packets. It really needs to run at the same level as the built in VPN client. Is there a DDK like kit that lets you write at the driver level on Android?

When you say "raw" sockets you might simply mean sockets as opposed to something like comet type hacks in a browser.
If that is the case, here is a nice tutorial for sockets in Android... Does this help you?

I need to get access to the Raw data, not just access a tcp/udp socket. Nice example though.
