Orbot has some commonly used features such as support for bridges. We now have an Android webpage that discusses the Orbot Android package in some detail. Everything you'll need for using Tor is in the package.

Orbot should be orders of magnitude safer than other Tor implementations on Android and it's our official release. This Android package is using the C reference implementation of Tor. We've codenamed the Tor on Android project Orbot Orbot is a single Android package that provides a new Tor controller, Privoxy as our trusty little HTTP proxy, libevent, and Tor itself. Please be cautious with this release, it's probably pretty fragile and it's certainly not ready for serious use. The Android web browser is not protected by Torbutton and we have not yet developed an anonymous browser on the Android platform. This is an early beta release and is not yet suitable for high security needs. The Tor Project has been working very closely with Nathan Freitas and The Guardian Project to create an Android release.
