Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

Photos from the Web to our application

We now have an application that is aware of its position on the globe and we will now capitalize on that feature by searching for photos taken within a 5-km radius. All these photos will be (of course) retrieved from the web and then added to our ListView component.

There is a web service for that...

There are many online photo websites out there and Flickr is still a very popular service that is widely used today. Moreover, it provides an API that will allow us to retrieve photos using geographic data.

Getting our API key

Similar to what we did when we interacted with social networks, we need to identify our application to the Flickr service. To do this, all we need is a Flickr account. It's basically a Yahoo ID, but the service now allows users to log in using their Facebook or Google credentials.

Once logged in, we will create our new application at the following URL:

From there, we will request an API key...
