app.js

var window = Ti.UI.createWindow({
	backgroundColor : '#000'

// create button, register the modified click callback, add button to window
function addButton(title, clickCallback) {
	var button = Ti.UI.createButton({
		title : title,
		width : '300',
		height : '50'
	});

		Ti.Media.showCamera({
			mediaType : Ti.Media.MEDIA_TYPE_PHOTO
		});
		clickCallback();
		Ti.Media.vibrate();
	});

	window.add(button);
}

// camera with front specified after switching to back
// checks if switch function actually works, opposed to it being the default
addButton('Front Camera Test 2', function() {
	Ti.Media.switchCamera(Ti.Media.CAMERA_BACK);
	Ti.Media.switchCamera(Ti.Media.CAMERA_FRONT);
});
