Things to commit just before leaving your job
// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.

// I've tried to capture interesting suggestions here.

Easily setup an Android development environment on a Mac

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)"
