I have a working php server on my android tablet, so I hope it's available somehow to run nodejs also. The source code is available on github, and it can be build on linux also, but I can't really understand, how to build it.
Thanks in advance,
The instructions for a build are missing from the website:
tar xzf node-v0.8.1.tar.gz
Go to the unpacked folder:
sudo make install
You might need to install some dependencies like
There is also a packaged Android port but it doesn't seem to be actively mantained.
edit: apparently you need to modify some build options according to your device. A google search for "node android" + your model should give you more details. Here are they for the G1 and Galaxy S: http://mitchtech.net/node-js-on-android-linux/
