Tor is available for Android by installing our package named Orbot.
Orbot is an application that allows mobile phone users to access the web, instant messaging and email without being monitored or blocked by their mobile internet service provider. Orbot brings the features and functionality of Tor to the Android mobile operating system.
Orbot contains Tor and libevent. Orbot provides a local HTTP proxy and the standard SOCKS4A/SOCKS5 proxy interfaces into the Tor network. Orbot has the ability to transparently torify all of the TCP traffic on your Android device when it has the correct permissions and system libraries.

Follow these instructions to install from Guardian Project’s repository.

Proxy settings and configuration
Orbot offers three interfaces into the Tor network:
SOCKS 4A/5 proxy 127.0.0.1:9050
HTTP proxy 127.0.0.1:8118
Transparent proxying (on select devices)
Platform specific notes
For standard Android 1.x devices:
The Orweb browser available in the Android Market integrates directly with Orbot, and offers a number of other privacy-oriented features.
For Instant Messsaging, try Gibberbot, which includes support for connecting via Tor and Off-the-Record encryption.
For Android 2.x devices:
You must root your device and update the firmware to an iptables-capable ROM for Orbot to transparently proxy all TCP traffic.
For non-modified and non-rooted phones, you’ll want to manually configure HTTP or SOCKS proxy settings for specific applications.
If you root your device and install an iptables-capable ROM (such as Cyanogen), Orbot can transparently proxy traffic on an app-by-app basis through Tor.
You can also install Firefox for Android from the market with the Proxy Mobile Add-on or install the text-only “NDBrowser” from the Android Market. Both of these solutions all routing of web access through Tor on standard, un-rooted devices.
For Instant Messaging, try Gibberbot, which includes support for connecting via Tor and Off-the-Record encryption.
Source code access
All of the source code is available in the Orbot git repository..
Note that this might not always give you the latest stable Tor version. Additionally, the Android web browser does not have Torbutton. This means that while it may be useful for circumvention, it probably is unsuitable for strong web browser anonymity requirements.
Tor Browser for Android is the only official mobile browser supported by the Tor Project, developers of the world’s strongest tool for privacy and freedom online.
Note: For this release, you also need to install Orbot, a proxy application that will connect Tor Browser for Android with the Tor network. For the upcoming Tor Browser for Android stable release, our goal is for Orbot not to be necessary to connect to Tor.
Known issue: Our Security Slider is now under ‘Security Settings,’ but because of a small issue, it’s only showing up after you restart the app. We plan on fixing it for the next release.
DEFEND AGAINST SURVEILLANCE
Tor Browser prevents someone watching your connection from knowing what websites you visit. All anyone monitoring your browsing habits can see is that you’re using Tor.
Tor aims to make all users look the same, making it difficult for you to be fingerprinted based on your browser and device information.
When you use Tor Browser for Android, your traffic is relayed and encrypted three times as it passes over the Tor network. The network is comprised of thousands of volunteer-run servers known as Tor relays. Watch this animation to learn more about how it works:
With Tor Browser for Android, you are free to access sites your local internet service provider may have blocked.
