Starting an Android emulator automatically on MacOSX after Login via LaunchAgent

Homebrew offers a simple means to install additional software packages on your MacOSX computer. After initial installation of brew as admin user execute:

brew install android-sdk # will install the newest SDK starter package
android update sdk # this will open the UI, now install all platforms
chgrp -R staff /usr/local/Cellar/android-sdk/r7 # otherwise the ANDROID_HOME will be owned by the wheel group and you may not start anything as non admin user.

To use tools like the emulator add ANDROID_HOME and ANDROID_SDK_ROOT to your $HOME/.profile or $HOME/.bash_profile (if the latter exists, use this):

ANDROID_SDK_ROOT=/usr/local/Cellar/android-sdk/r7
ANDROID_HOME=$ANDROID_SDK_ROOT
export ANDROID_SDK_ROOT ANDROID_HOME

Create an emulator called Wildfire using the android command. Now if you want the emulator to be started automatically after you login, put the following into $HOME/Library/LaunchAgents/emulator-wildfire.plist:

	<?xml version="1.0" encoding="UTF-8"?>
	<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

	</dict>
	</plist>

After you saved the file, execute launchctl load $HOME/Library/LaunchAgents/emulator-wildfire.plist. From now on the emulator starts whenever you (or your CI user) logs in.
