Summary

BlackBerry Java and WebWorks both offer unique and compelling reasons for using them, with both having upsides and downsides.

RIM is innovating and changing how development is performed, which again is extremely frustrating to developers

With BlackBerry losing market share at an alarming rate, it’s important that you do not dive right into creating a BlackBerry app without ensuring that it is the best business decision.

An app aimed at state government or education may be a great fit for BlackBerry.

As with all platforms, don’t just develop for the platform because everyone else is doing it.

Chapter 10

Getting Started with Appcelerator Titanium

What’s in this Chapter?

Appcelerator Titanium was released in December 2008, and has been steadily growing in functionality since its release.

Starting with its Titanium Developer product, Appcelerator provided a single-point interface to run applications.

As features were added to the Native iOS SDK, Titanium released a new, major revision, and each minor version included bug fixes and code to bring parity between Android and iOS.

Why Use Titanium?

The primary development languages for Titanium are HTML, CSS, and JavaScript.

The compile process generates iOS and Android source code, as well as a distributable binary, respective to each platform.

By leveraging the Titanium framework developers are provided a single way to create all of their UI, transparent to the native codebase.

Who is Using Titanium?

NBC, GetGlue,

Appcelerator keeps track of its user base through the login contained within the IDE

When creating projects in Titanium Studio, your login name is registered with your project’s App Id, so Appcelerator understands how many apps you are developing

Appcelerator makes sure to let all the developers know when new features and versions are being released

Every quarter, Appcelerator, along with IDC (an IT market analysis and research firm), release their mobile developer analytics report from information gathered from developer surveys

Summary

Titanium is not a magic bullet. It is a solid framework for developing a single codebase to deploy to multiple platforms.

Titanium allows developers to use a language they are more familiar with to create apps in a domain outside of their knowledge.

Titanium is not an exact match to native languages. Not all features of the mobile platforms are exposed (or can necessarily be exposed) in its API.

With the addition of Titanium Studio, developing in the framework has grown by leaps and bounds.

The team at Appcelerator works to pack as much functionality into their framework as possible.

Titanium is an excellent tool to learn mobile device programming, and for many projects can provide the necessary functionality to deliver a finished product.
