Non blocking IO for Android

Question

I'm currently trying to assess whether a project can be realised for Android. One major problem I see it that, since it's a P2P client, we'd have to keep a considerable amount of connections open when running. Now the connections do not transfer large amounts of data, it's more of a messaging system, so having a thread for each connection creates a useless overhead if we're reading a single message of 64 bytes every now and then.

So I was wondering whether there is support for non blocking IO such as select() or poll() on Linux.

Any suggestion?

Check out java.nio Sockets, Selectors, and Channels. Some links:

Or, maybe I didn't read your question right.
