Google details low-level Renderscript API for Honeycomb

There’s no question that Honeycomb tablets like the Xoom are powerful pieces of hardware, and it looks like Google will be doing its best to ensure that developers are able to exploit as much of that power as possible. A big piece of that puzzle is the company’s Renderscript API for the OS, which it’s just now starting to detail in full. The big advantage there is that it’s a low-level API designed especially for developers who are “comfortable working closer to the metal,” which will let applications built with it (including games) take full advantage of the high-end GPUs and dual-core processors found in Honeycomb tablets. What’s more, while the API is just now being made public, it’s already been put to use in Honeycomb by Google itself — both the YouTube and Books apps, and the live wallpapers shipping with the first Honeycomb tablets were created with the help of it. Head on past the break for another quick example — a brute force physics simulation that involves 900 particles titling with the tablet — and look for Google to provide some additional technical information and sample code sometime soon.

Nokia to developers: no Qt for Windows Phone development

Nokia’s been beating the Qt warpath for years after purchasing the developer framework from Trolltech back in January of 2008. In fact, Nokia just made the switch to Qt exclusively back in October in a sign of its unrelenting support for the unified development environment. That, like all previous Nokia strategies, is in for a big change today. While Qt will continue on as the development framework for Symbian and MeeGo, Microsoft will provide its free Windows Phone Developer Tools (Visual Studio 2010, Expression, Silverlight and the XNA Framework) to developers interested in developing for Nokia Windows Phones (get used to that phrase) while providing “guidance” to anyone wishing to port their apps to WP7. In other words, Qt will not be adapted for Windows Phone 7 APIs. Full letter after the break to what we imagine is a very disgruntled and previously loyal Nokia developer community.

webOS Enyo framework free to developers today, brings pixel density agnostic apps to phones, tablets and PC (video)

Development frameworks don’t make for exciting gadget news, but HP’s Enyo is kind of a big deal. It’s the little dealie that allows new webOS apps to stretch between vastly disparate screen resolutions — say, tablet and phone — and still work just fine, and since it’s based completely on web technologies, they can also run in a PC browser with no formal emulator or OS install required. While dev team lead Matthew McNulty pitched the browser functionality as a debugging boon, we’re starting to wonder if that’s how HP could bring webOS to PCs to start — rather than a dual-boot or a UI layer, it could simply make your favorite apps available in a web store. Sound like fun? HP says you can download the basic package right now for free if you’re a member of the webOS developer early access program, and start cracking on some apps of your very own. We’ll have video of an Enyo-powered app on PC in just a tad, so keep your eyes glued to this post.

Update: Video after the break!

Android 2.3.3 announced with more developer-friendly access to NFC

The Android versions keep on rolling today with the introduction of a new build in the 2.3 Gingerbread line — 2.3.3 this time — that improves developer access to the platforms newfound NFC capabilities as first seen on the Nexus S. What’s new, exactly? Well, there’s a new NFC read / write API that Google alleges will let you access pretty much any NFC tag on the market today, better control over what happens when a tag comes within range of the device, and “limited support” for peer-to-peer NFC communication — something Stanford cobbled together for the Nexus S not long ago. The new build is available now to developers using the Android SDK; no devices have received an update yet, but we’d imagine the Nexus S is queued up to get it before too long.

Google shows off Fragments API for Android 3.0

Following up on its Android event on Wednesday, Google is giving us an in-depth look at Honeycomb’s Fragments API: a tool designed to make developer workflows more fluid. As the name suggests, Fragments are smaller pieces of the larger UI puzzle, allowing you to independently control and reuse certain aspects of an action in their own modular space. These modules, like the panes that came before them, are also meant to make the transition from different screen sizes (tablet to phone, for example) simple and functional. We got a glimpse of Google’s new API in action with a demo of CNN’s new tablet app, and despite its everything-and-the-kitchen-sink aesthetic, it looks like an easily navigable interface. While Honeycomb is currently a tablet-only OS, Matias Duarte hinted strongly that it would eventually make it to phones, and indeed, the screenshots of Fragments in use are all suspiciously phone-sized. What’s more, Google intends to bring Fragments to older Android versions through a static library — there’s no timeline, but the plan is to go as far back as Android 1.6. Now that’s Android fragmentation we can get behind.

Microsoft rolls out copy and paste update to Windows Phone 7 developers

There’s still no word on a public release, but Microsoft has now finally at least given Windows Phone 7 developers the long-awaited gift of copy and paste. That word comes straight from Microsoft’s director of developer relations, Bandon Watson, who confirmed today’s release on the PPCGeeks podcast last night, and also announced that the Windows Phone Developer Tools software was about to cross one million download mark. In addition to copy and paste, the new update also includes a number of performance improvements that promise to speed up application launch times — here’s hoping the release is also a sign that Microsoft is about to speed up the roll out to Windows Phone 7 users.

Google said to be hiring ‘dozens’ to boost Android app development

We’ve already heard of some changes that Google’s planning to make to boost app purchases in the Android Market, and it looks like it’s now also undertaking a considerable in-house effort to increase the number of quality apps that are available. According to The Wall Street Journal, Google is planning to hire “dozens” of software engineers, product managers, user-interface experts and “others who have ideas for mobile apps,” and it’s apparently already shifted some of its current employees to work in this new “apps lab.” As you might expect, that’s being done at least in part to close the so-called “app gap” with Apple, and it looks like the new apps will reach far beyond Google’s usual properties — the WSJ even specifically mentions games as one area they’ll focus on. The apps would also apparently all be free (but possibly ad-supported), and Google is said to be trying to woo developers with its distribution power, noting that it will be able to promote the apps in the Android Market and even have them pre-installed on many phones.

Visualized: Google’s periodic table of APIs

The world of Google APIs and developer tools can be a confusing one, but the company has now at least brought a bit of order to the chaos with its own take on the periodic table of the elements. As you can see above, Android occupies the top spot normally reserved for hydrogen in the actual periodic table, and the remaining APIs and developer products are all grouped into their appropriate categories — and, of course, linked to their respective websites. Hit up the link below to check out the table in its interactive form.

Android App Developer Interest Increases With Wave of New Tablets


While Apple’s iPad dominated tablet sales in 2010, there may be room for change in 2011. Enthusiasm for Android app development is rising fast in the coding community.

And that means the apps available to Android users is set to grow — fast.

A recent global survey of app developers by research firm IDC shows 74 percent of respondents as “very interested” in developing for upcoming Android OS-running tablets, up from 62 percent three months ago.

The survey, which questioned over 2,200 app developers around the world, cites the surge in new tablet debuts for 2011 as the reasoning for increased developer interest. At CES in January, manufacturers debuted 85 new tablets, the majority of which were running Android.

“My intuition is that Android is picking up that Linux, open-source crowd that feels excited to move from iOS development to an open platform,” Andreas Schobel, CTO of popular Android app developer Catch.com, told Wired.com in an interview. “The way you can weave Android applications together with Intents makes it a very sexy platform, but one that requires a lot more discipline and effort. Like a powerful, yet complicated, science kit.”

And they’ll be cranking out the apps at a breakneck pace. Respondents to the survey plan to develop an average of 6.5 apps in 2011, almost twice as many as last year. Apple’s App Store has over 400,000 apps currently available for download, while the Android Market offers around 200,000 apps.

2010 was Apple’s year to shine in the tablet market. In the company’s recent earnings report, Apple reported 7.33 million iPads sold in the fourth quarter of 2010. We’ve yet to see that type of traction from an Android tablet — Samsung reported sales of 1 million of its Galaxy Tab in December.

And the iPad still leads the tablet pack in terms of developer interest, with 87 percent of respondents expressing interest in it. But developers aren’t necessarily beholden to one specific platform. Those surveyed plan to develop apps for four different devices on average, the big four being the iPhone, iPad, Android phone and Android tablet.

Although the pack seems eager to produce more Android apps in the coming year, developers aren’t without their concerns. About half of the respondents expressed concerns around version fragmentation. Google has been in the habit of pushing two Android updates per year, which means multiple versions of software for developers to configure for multiple platform versions. Handset manufacturers tweaking the firmware for each model of phone can also be hell on a developers’ workload.

It’s the cost of doing business with an open platform like Android. And judging by IDC’s numbers, it’s a cost developers are willing to pay.

iOS 4.3


Apple this week released a beta version of its next mobile operating system, iOS 4.3, for app developers. We got an early look at the OS, which has not been released to the public yet.

Among a pile of minor interface modifications, there are a few major new features under the hood.

Some new multitouch-gesture controls on the iPad are the biggest goodie. In the developer release we saw, at least, the feature is hidden until you use a Mac app to enable it. This new feature is awesome, and it’s definitely something to look forward to when iOS 4.3 officially ships. (Apple has not disclosed a release date, but we’re guessing soon).

The rest of the changes we found were interface-related — modifications to the iPad keyboard and the iOS multitasking tray, a new notebook font and more.

Here’s a rundown of what’s new in iOS 4.3 beta.
