WARNING: This method is still untested, and needs corrections (I'm just guessing based on the tutorial in the previous version, since I don't have an Android phone)

1. Download and install Proxoid to your Android device
2. Connect that device to your computer via USB
3. Launch Proxoid, and start the service
4. On your Android device, from home screen: Menu > Settings > Applications > Development > USB debugging (make sure it is checked)
5. Press Ctrl-Shift-T. When the terminal appears, type the following:

   sudo echo "SUBSYSTEM==\"usb\", ATTRS{idVendor}==\"0bb4\", MODE=\"0666\" >> /etc/udev/rules.d/90-android.rules
   

6. Download the Linux version of the Android SDK, and then type the following command in the terminal (replacing ”/path/to/android-sdk_rXX-linux_86.tgz” with the path to the file you downloaded):

   tar -zxf /path/to/android-sdk_rXX-linux_86.tgz ~ 

7. Type the following commands: The path is a guess

   cd ~/android-sdk_rXX-linux_86/tools
   ./adb forward tcp:8080 tcp:8080
   

8. Set Chromium's proxy settings to use port 8080 of localhost
