Build XBMC for Android on lubuntu 12.04

1. install required packages

# sudo apt-get install build-essential default-jdk git curl autoconf \
   unzip zip zlib1g-dev gawk gperf

2. Getting the Android SDK and NDK

http://developer.android.com/sdk/index.html

SDK : android-sdk_r20.0.1-linux.tgz

crystax-5 NDK with enabled support of C++ exceptions, RTTI and Standard C++ Library 

http://www.crystax.net/en/android/ndk/7#download

NDK : android-ndk-r7-crystax-5.beta2-linux-x86.tar.bz2 

3.Installing Android SDK packages

<android-sdk> : $HOME/XBMC_Project/android-sdk-linux

# cd <android-sdk>/tools

# ./android update sdk -u -t platform,platform-tool

4.Setup the Android toolchain

<android-ndk> :  $HOME/XBMC_Project/android-ndk-r8b

<android-toolchain> :  $HOME/XBMC_Project/android_toolchain/android-9

# cd <android-ndk>
# ls platforms
# cd build/tools
# ./make-standalone-toolchain.sh --ndk-dir=../../ \
  --install-dir=<android-toolchain>/android-9 --platform=android-9

5. Create a (new) debug key to sign debug APKs

All packages must be signed. The following command will generate a
self-signed debug key. If the result is a cryptic error, it
probably just means a debug key already existed, no cause for alarm.

# keytool -genkey -keystore ~/.android/debug.keystore -v -alias \
  androiddebugkey -dname "CN=Android Debug,O=Android,C=US" -keypass \
  android -storepass android -keyalg RSA -keysize 2048 -validity 10000

6. Getting the source code

# cd $HOME/XBMC_Project
# git clone git://github.com/xbmc/android.git xbmc-android-git
# cd xbmc-android-git
# git submodule update --init addons/skin.touched

7.Building dependencies

# cd $HOME/XBMC_Project/xbmc-android-git/tools/android/depends

# ./bootstrap
# ./configure --help

#export XBMC_ANDROID_NDK=~/XBMC_Project/android-ndk-r7-crystax-5.beta2

#export XBMC_ANDROID_TARBALLS=~/XBMC_Project/xbmc-tarballs
