Easily setup an Android development environment on a Mac

instructions.md

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

Install Homebrew:

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

Use Homebrew to install Android dev tools:

brew install ant
brew install maven
brew install gradle
brew install android-sdk
brew install android-ndk

Install all of the Android SDK components (you will be prompted to agree to license info):

android update sdk --no-ui

Install HAXM for blazing fast emulators. Check out the "Configuring VM Acceleration on Mac" section here: http://developer.android.com/tools/devices/emulator.html

Update your environment variables:

export ANT_HOME=/usr/local/opt/ant
export MAVEN_HOME=/usr/local/opt/maven
export GRADLE_HOME=/usr/local/opt/gradle
export ANDROID_HOME=/usr/local/opt/android-sdk
export ANDROID_NDK_HOME=/usr/local/opt/android-ndk

Update your paths (bonus points to a better solution to the hardcoded build tools version):

export PATH=$ANT_HOME/bin:$PATH
export PATH=$MAVEN_HOME/bin:$PATH
export PATH=$GRADLE_HOME/bin:$PATH
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH
export PATH=$ANDROID_HOME/build-tools/19.0.3:$PATH

Periodically run these commands again to ensure you're staying up to date:

brew update
android update sdk --no-ui
