-This document explains how to properly build an Android package of Orbot from -source. It covers building on Debian Lenny (5.0.3). +The Orbot repo also includes the Privoxy source code of a recent stable release.
Please install the following prerequisites (instructions for each follows): ant: http://ant.apache.org/ - Android OS SDK: http://source.android.com/download - droid-wrapper: http://github.com/tmurakam/droid-wrapper - libevent source (1.4.12-stable from svn) - Tor source (most recent git master branch) - Privoxy source (http://sourceforge.net/projects/ijbswa/) - -Install and prepare the Android OS SDK ( http://source.android.com/download ) -on Debian Lenny: - - sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf \ - libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip \ - curl libncurses5-dev zlib1g-dev valgrind libtool automake \ - ruby subversion - update-java-alternatives -s java-1.5.0-sun - - mkdir ~/bin - PATH=~/bin:$PATH - curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo - chmod a+x ~/bin/repo - - mkdir ~/mydroid - cd ~/mydroid - - repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.7_r1 - repo sync - - # Paste in key from http://source.android.com/download next... - gpg --import - - cd ~/mydroid - - # This takes a long while... - make - -Install droid-wrapper: - - cd /tmp - git clone git://github.com/tmurakam/droid-wrapper.git - cd droid-wrapper - sudo make install - -zlib and OpenSSL are included with the Android OS SDK.

This will produce an unsigned Tor package in ./bin/Orbot-unsigned.apk!
