-- Note:
-- This is used for Cocos2dx + Lua
-- This is a script to making .APK file for android platform
-- Make sure you have installed java, ant, android sdk, ndk, svn, jit
-- Also plz check and rewrite following paths before you use this script
-- Remarks:
-- The script will update your cocos engine directory and your Lua script which probably is Resources
-- then it should jit your Lua files , use ASMaker to encrypt your Lua-jit files 
-- all files and resources will move to this folder proj.android/assets
-- finally it will make a .APK package with ANT
