Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH=/Users/yingray_lu/.oh-my-zsh

# Set name of the theme to load. Optionally, if you set this to "random"
# it'll load a random theme each time that oh-my-zsh is loaded.
