Carbide .c++ Professional Edition
Mike Trujillo; Product Marketing Manager
Nokia is moving upstream from their base mobile phone market into high-end, multifaceted, and extremely versatile portable computing devices that just happen to be shaped like a phone. Make no mistake, though, these computing powerhouses often pack more audiovisual, screen resolution, and storage capacity than many laptops only a couple years old. And while developing applications for this embedded platform isn't a trivial task, Nokia has eased the burden considerably with their Eclipse-based Carbide C++ development environment. Most of the upper-tier Nokia models run the Symbian operating system, requiring a special C++ compiler and linker to convert code into executables. Once developers select the type of Nokia device they wish to target and load its profile into Carbide, applications can be first written and monitored in the virtual emulator before sending to the actual device. This is especially useful for apps that consume network resources.
A fairly hefty rig is required to run Carbide due to its Eclipse underpinnings, and the virtual sessions and debugging overhead and tweaking the platform for the optimal configuration takes some effort but once set up, it offers developers a stable, effective environment to create great mobile programs. The main reason for this is Carbide's built-in performance monitors (called the "Performance Investigator"), which graphically analyzes on-board device performance data, and crash debuggers for faster identification of program errors. A user interface designer considerably reduces the time to hack out a front-end, supplying a palette of popular UI controls for faster mock-ups of the next killer concept. And Nokia's developer forums offer a community abuzz with code snippets, best practices, and dynamic interchange of ideas and solutions for even the most obtuse coding issues. Any developer enthralled with the idea of creating applications on Nokia's advanced mobile devices needs the Carbide IDE to realize their visions on the Nokia platform.
AppForge has been a perennial Jolt Judge favorite. It provides -- or rather, provided -- a plugin to Visual Studio, letting you lay out device applications quickly and easily, write code that dealt very well with mobile issues like intermittent aperiodic synchronization, and most importantly, hid the platform differences so that you could seamlessly "write once, deploy many" to just about every PDA, phone, or handheld of interest. So their Productivity Award this year was well-earned.
But as of late last month, AppForge's website went dark, redirecting to Oracle home page without a hint of explanation. Developers and consultants say they were left twisting in the wind, unable to activate new licenses or even deploy applications on new devices. Since then n lews has been slowly released that Oracle has bought out the intellectual property rights.
No further information was available at press time. The Jolt judges are sorry to see Crossfire go; even more, we wish its apparent demise had been handled with a bit more grace. Our sympathies to the developers and end users.
NetBeans Mobility Pack 5.5 and Sun Java Wireless Tookit 2.2
If you haven't tried the NetBeans IDE lately, you owe yourself a treat. Try it out and see how easy mobile application development can be.
The overall integration with the clean NetBeans environment makes development much quicker than most, if not all, vendor-specific IDEs. It supports multiple device configurations for each application that greatly reduce duplicate coding, and it supports multiple third-party emulators to speed-up the testing process. Of course, the GUI builder, Ant build tool, and debugger all help to make developers that much more productive.
The 5.5 version of NetBeans Mobility Pack now supports JMUnit for unit testing, SVG Graphics for vector graphics and animation, and many platforms, including Windows CE. ItÕs a great package for mobile development!
The Qtopia Phone Edition is a complete UI and application framework for Linux-based mobile phones. For application developers, Qtopia is similar to TrollTech's Qt framework (a cross-platform UI framework for PCs). Hence, Qtopia makes it easy for the 150,000+ existing Qt developers to develop mobile phone applications.
Unlike Qt, Qtopia is much more than a UI framework. In fact, it provides all features we normally expect from an operating system. Based on the Linux kernel, Qtopia embeds a compact windowing system; supports a variety of input methods (e.g., keypad, touch screen, stylus), network protocols (e.g., GPRS/3G, WiFi, Bluetooth), and media formats; and provides a complete set of basic phone applications, such as voice call management, calendar, address book, messaging, media player, web browser, and the like. Third-party Qtopia applications have access to all the C++ APIs in the underlying operating system, allowing developers to unlock the full potential of the phone.
But perhaps the biggest problem is that Qtopia phones are hard to find. So far, Motorola is the only big name phone manufacturer to adopt Qtopia on some of its low-volume phone models. Developers writing Qtopia applications will find a very limited audience. That is in stark contrast with Qt developers whose applications can target almost all PC users.
