iPhone and Android development with Titanium

Over the past few months I’ve worked on a couple of mobile applications for the iPhone and Android platforms. I’d looked at Phonegap some time before that, but determined that it wasn’t up to the job, but more recently I stumbled across Titanium from Appcelerator. The idea is that you code up your apps using HTML and Javascript. The Javascript calls the Titanium API to create things like lists, dialog boxes, and phone features such as geolocation.

Some of the advantages of using Titanium are:

– No need to learn Objective-C (iPhone) or Java (Android)
– Leverage existing HTML + Javascript skills
– Write one version of the code that can be deployed to both platforms
– Code is compiled up into native applications which are accepted in the App Store
– Potential to deploy to other platforms in the future (e.g. Blackberry, Symbian)

The level of support provided by the Appcelerator staff on the official forums is brilliant, and the tutorial videos are good for those who want to get an overview of creating apps without wading through documentation.

You’ll still need a Mac if you want to develop for the iPhone, because Titanium makes use of the iPhone SDK. But if you just want to do Android development then you can use Window or Linux as well.

Although you’ll be developing 1 set of code for both the iPhone and Android, you’ll probably want to customise the UI slightly differently for each platform. For example, Android apps often hide away items such as ‘Settings’ and ‘Help’ under the Menu button. It’s simple to code this kind of thing up:

	if (Titanium.Platform.name == 'android') {
		var menu = Titanium.UI.createMenu();
		menu.addItem("Help/About", function() {
			displayWindow('Help / About', 'window_about.html');
		}, Titanium.UI.Android.SystemIcon.HELP);
		Titanium.UI.setMenu(menu);
	} else {
		data.push({title:'Help / About',image:'tabicon_help.png', color:'#ffffff'});
	}

That code will create the Help/About option under a menu on Android, and add it to the home screen’s list on the iPhone. Simple.

Titanium is an awesome framework so if you’re considering developing for the iPhone and/or Android then I’d highly recommend you take a look.
