What is the best way to use Restlet in Eclipse? Of course, you could manually use the JAR files in your Eclipse projects, but the most flexible way is to rely on Eclipse's plug-in infrastructure.

Read this document to learn about the range of application types you can develop for iPhone OS and the human interface design principles that inform all great software.

The Android UI team has begun developing guidelines for the interaction and visual design of Android applications. Look here for articles that describe these guidelines as we release them.

if you are looking for barcode iPhone apps that work, here are 5 apps you should try:

With this week's release of Verizon Wireless' Droid phone comes the first real test of the potential for fragmentation with Android. The Droid will be the first phone to run Android 2.0. After it goes on sale Friday, there will be Android phones on the market running three different versions of the OS.

Google gave an equally vague answer to questions about which phones might be upgraded and if any of them had hardware limitations that might prevent an upgrade. "Because Android is open source, all software updates we release are available for carriers and handset makers to take and update their current or future Android-powered devices," Katie Watson, a Google spokeswoman said via e-mail.

With the introduction of Android version 1.6, support was added different screen sizes.  The platform does a nice job of letting developers tell the market what size screens their app supports, but that’s only half the story.

This means that every game will have to support 6 unique screen configurations in order to look its best on every phone!

5 app stores under the microscope

Last week, we learned that Apple would be revamping some US retail stores, including a new iPod touch-based point-of-sale (POS) system. A new scanner accessory allows Apple to replace the old Windows CE-based sales handhelds.

According to the report, more than one mobile subscriber in 10 in developed regions will use mobile coupons by 2014. As a result, Juniper is confidently forecasting that consumer usage of mobile coupons could potentially generate upwards of $6 billion globally in retail redemption value by 2014.

ARPU from NFC coupons and smart posters will exceed ARPU from NFC payment transactions The vast majority of mobile coupon redemption value will be generated by the Far East & China, Western Europe and North America in 2014

Last week, we introduced expanded mobile reporting features in Google Analytics. To help developers, this launch includes features that make it easy to see how people are using specific parts of their iPhone and Android applications. The same Google Analytics reports that provide insights into website traffic and engagement are now available for mobile apps.

Like other Android gadgets, the Droid’s app storage is limited to a meager 256MB. Yes, it comes with a 16GB SD card that can be replaced with a 32GB card, but there’s likely to be some backlash from consumers who’ve never used removable memory before. The Droid’s browser is inferior to the iPhone 3.1 Safari browser, according to MobileCrunch, with slower page loads and slightly less compliance to web standards. While the European version of the Droid — which is dubbed the Milestone — features a multitouch screen, the U.S. version does not, eliminating the ability for users to pinch and zoom as they can on the iPhone.

"Mobile will become the center of your digital channel relationships," Harteveldt said, pointing to 36% of smartphone users who access the Web daily from their devices. One in four use the device to research products they will buy either online or offline. The heavy lifting needed to become an effective multichannel marketer often involves eliminating silo operations; aggregating, analyzing and acting on consumer-profile data from across the company; and integrating online and offline consumer marketing, sales and service.

In a grab for young male consumers, Pizza Hut is using social media and mobile connected devices to partner with Electronic Arts Sports and other video game companies, fight night and films such as Terminator 4.

Forrester reports that online captured 29% of consumers' reported general merchandise retail spending in the second quarter of 2009. Half of all online Americans participate in social networks, a number that has increased 46% in the past year.

For Apple (AAPL), the short answer is: The iPhone will continue to apply the Macintosh method—that is, controlling all or most of the user’s experience—with similar results: smaller market share, disproportionally larger profits than the separate hardware-software crowd. More on this later.

We consider a mobile ad hoc network setting where Bluetooth enabled mobile devices communicate directly with other devices as they meet opportunistically. We design and implement a novel mobile social networking middleware named MobiClique. MobiClique forms and exploits ad hoc social networks to disseminate content using a store-carry-forward technique. Our approach distinguishes itself from other mobile social software by removing the need for a central server to conduct exchanges, by leveraging existing social networks to bootstrap the system, and by taking advantage of the social network overlay to disseminate content. We also propose an open API to encourage third-party application development. We discuss the system architecture and three example applications. We show experimentally that MobiClique successfully builds and maintains an ad hoc social network leveraging contact opportunities between friends and people sharing interest(s) for content exchanges. Our experience also provides insight into some of the key challenges and short-comings that researchers face when designing and deploying similar systems.

A Survey of Platforms for Mobile Networks Research

Auditory contexts are recognized from mixtures of sounds from mobile users’ everyday environments. We describe our implementation of auditory context recognition for mobile devices. In our system we use a set of support vector machine classifiers to implement the recognizer. Moreover, static and runtime resource consumption of the system are measured and reported.

More and more companies are creating iPhone applications as a way to reinforce branding and to gain new customers. Some companies are even seeing increased sales thanks to iPhone apps. One of those is the Pizza Hut app [iTunes link] for the iPhone and iPod touch, which has now generated more than $1 million in sales according to MobileMarketer. The US-only iPhone app was first introduced three months ago.

People have long shared product opinions with friends and family through word-of-mouth. Today, social media tools enable consumers to extend their connections and conduct commerce in powerful new ways.

Social network users are a highly coveted group of consumers. Across all age brackets, they were more likely than average to make an online purchase, according to a May 2009 survey by Anderson Analytics. What’s more, social network users are sharing recommendations with greater frequency than generally expected. A Q1 2009 Razorfish survey of social network users found that some 29% reported sharing their views online at least every few weeks, while 10% said they made such contributions at least every few days.
