Inject environment variables into Titanium. Makes shared code easier to manage (no more sanitizing keys in repos). Uses Titanium to encrypt the values.

app.js

// now you can use it in a titanium app
useSomeApi(Ti.App.Properties.getString('SOME_API_KEY'));

hook.js

exports.init = function (logger, config, cli, appc) {
	cli.addHook('build.pre.compile', function(build, done) {
		// inject the environment variable straight into the tiapp. By doing this prior to compiling,
		// it will be encrypted and made available via Ti.App.Properties.getString()
		cli.tiapp.properties.SOME_API_KEY = { type: 'string', value: process.env.SOME_API_KEY };
		done();
	});
};

How could you inject a Google Maps API Key into the android manifest part of tiapp.xml ?

Hi Tony ,
I am also trying to create build for QA and Production with differnt Tiapp Configuration , In above example , i can not find the the way to call init , and it's argument. Do we need to call init explicitly or it gets called implictly.
I have added above init function in alloy.jmk file but it never gets called.

Please suggest.
