	- download the jar file from here: https://mega.co.nz/#!pd81gYBA!ui33ktU2xDqmcsYOv5oSZ6v-niPp1ofwh02naT7Vqbs Note that anytime you import any other plugins make sure that file doesn't get overwritten!
	- overwrite the file with the same name in the Plugins/Android folder with the downloaded jar
	- generate an AndroidManifest.xml file
	- add the required permissions for Vuforia to the generated AndroidManifest.xml (see their docs for the details)

	Usage:
	var a = 'a very very long string to be squashed';
	var b = a.compress(); // 'a veryāăąlong striċ to bečquashed'

	In order to take part in the Unity Activity sharing system, there are a few steps you will need to take outlined below. First, some background. You can signify which class you would like to receive all the Activity lifecycle methods. When you implement the methods they should have the exact same signature but they should be public static void. That is important! They will not be called if they are not public static void. You can implement 1 or all of the methods. That is entirely up to your needs.


	1. Download the Prime31UnityActivity.jar file from here: https://app.box.com/s/xw6hq1ltjaniycc14j21 You are free to distribute the file but do not change it's name! That would defeat the purpose of the sharing mechanism!
	2. Implement any of the methods that are available in this Gist (https://gist.github.com/prime31/10747997)
	3. Perform the AndroidManifest changes below



	If successful, on app launch you will see a log that looks like the following:
