app.js

var win = Ti.UI.createWindow({
	backgroundColor: 'white',
	top: 0, left: 0, right: 0, bottom: 0,
	layout: "vertical"
});

var button = Ti.UI.createButton({
	title: "click me"
});
win.add(button);
button.addEventListener("click", function(e) {
	var data = Ti.Filesystem.getFile("test.json").read().toString();
	var obj = JSON.parse(data);
	label.text = obj.message;
});

var label = Ti.UI.createLabel({
	text: "<message>"
});
win.add(label);

win.open();

{
	"message": "hello world from json"
}
