Google used its I/O 2012 conference in San Francisco to unveil the latest release of Android. Carrying the version number 4.1, the new Android Jelly Bean is supposed to come as more of a polish to Ice Cream Sandwich, than a major game changer.
Don't think for a second though, that Jelly Bean doesn't have anything interesting to offer. On the contrary - the latest Android version brings a truckload of new features, and should help noticeably improve the overall user experience. Here goes the full breakdown:
Android 4.1 Jelly Bean changelog:
Project Butter has brought smoother and faster feeling user interface
Improved notification center with expandable and actionable notifications
Updated widget behavior
Improved camera and gallery apps for easy photo snapping and sharing
Improved keyboard behavior with with word prediction
Added Accessibility options with support for external Braille input
Enhanced Android Beam allowing transfer of photos and video
Offline Voice recognition and typing
Google Voice search is more intelligent than ever
Updated Google Search user interface
Google Now adds automatic information feeds to your device (weather, traffic, sports, etc)
Bi-Directional text and additional language support
Truly high-resolution contact photos
USB audio output and HDMI multichannel audio output
App encryption and Smart App updates
The list might not be too long, but Android ICS was arguably the most feature-rich platform already, so major changes were hardly required. With Android easily the most popular mobile OS out there, Jelly Bean's task is to solidify its lead by polishing the user experience.
The Project Butter sounds like a great start, but it's certainly not the only trick up Jelly Bean's sleeve. The revamped notification center, the updated widgets and the new natural language searches should really make a difference to end users, while the improved Android SDK and extended API support should keep developers happy.
The question remains if every feature on the list work as advertised, so let's not waste any more time and start testing them out. User interface awaits you on the next page.
User interface
Android 4.1 Jelly Bean sticks to the foundation laid by Ice Cream Sandwich more than half a year ago. There are very few visual user interface changes, but some cool added functionality. Of course, as with every previous Android release, the bootscreen animation has also been updated.
Project Butter
Project Butter is Google's answer to the oft-criticized Android user interface stutters and is probably the most important new feature of Android Jelly Bean. Cool animations have been an integral part of Android for quite some time now, but the problem was that they weren't always perfectly smooth. Even really powerful smartphones and tablets were guilty of the lagging occasionally and it was about time Google did something about it.
In fact, Google has worked so hard on these performance optimizations that it even borrowed the services of a high-speed RED camera to record the improvements throughout the UI.
To get the interface so fluid and smooth, Google has made Jelly Bean's UI run at 60 frames per second where the hardware allows it. Since software engineers didn't stop there, they also added triple buffering (CPU, GPU and display working in parallel, not waiting in turns).
Finally, there's the feature called Touch responsiveness, which makes your phone anticipate and predict where your finger will be on the screen next and preloads any animations it might need to display when you start touching the screen.
The result, as you saw in the video above is an interface you can safely call "smooth as butter".
Lockscreen
The lockscreen for example is altered and now shows a large dotted circle around the center-placed unlock button. You still the two familiar shortcuts - move the unlock button to the left for camera, and right for unlock. There's a new, third icon above them for jumping to Google Voice Search.
We still feel Google isn't utilizing the lockscreen to its fullest, though. A small weather widget would've come in handy, or even a short calendar snippet showing the upcoming appointments. We've seen those in some of the custom launchers, but it would be great if they were backed into the OS itself.
Enhanced notification center
One of the best bits about Jelly Bean is its revamped notification center. It features a redesigned clock and date icons on the top left followed by a larger settings icon. The clear notifications icon has also been refreshed and it looks much sharper now.
The updates here don't end with the looks, either. Select app notifications have gotten really smart, not only delivering you the notification, but also providing you with several options for interaction.
For example, you can snooze a reminder for an upcoming meeting or email its guests right from the notification area. This is quite convenient, saving you a few seconds from the time you'd normally spend tapping your way through the app to get the same thing done.
Next, you can answer or hang up a call right from the notification blind. Yes, this feature was present in previous Android releases too, but now it's icons have been redesigned don't feel out of place.
Finally, starting with Jelly Bean, you can view photos shared with you on Google+ or even read your incoming messages without even having to enter the Messaging app.
Resizable and self-aware app widgets
Ice Cream Sandwich introduced resizable widgets, and they have been further improved in Android 4.1 Jelly Bean. With the latest release of the Google OS widgets will automatically adjust their size to fit on the screen where you'd want to put.
This means that if you place a widget in an icon-congested screen, the widget will contract to fit in whatever gap is available for it. Also, if you drag one widget on top of the other, it will make space for itself by forcing the icons underneath to rearrange.
Google Now
Google Now is definitely one of the most interesting of the Jelly Bean novelties. To put it simply, it's Google's version of Siri, but it learns constantly about you from your daily routines. The weather sites you look at, the news and videos you watch in the morning and the routes and calendar appointments you create daily - Google Now uses them to give you provide better, more accurate results to your searches.
The service interacts with you by generating cards, which gives you short overview of information it believes is relevant to you right now. Going to work in the morning? Google Now knows this and lets you know there's a big traffic jam on your usual way to the office, so it offers you a re-route.
It can interpret a lot of things from your search history as well. If you've been searching for, let's say, your favorite football team, Google Now will prepare a card showing you the next match the team is playing and will provide you score updates once the game begins.
Google Voice Search
Naturally, search is where Google excels. And with its enhanced looks and heavily updated Voice search, it gives Siri a run for its money.
Now you can ask Google everything you want to know in natural human language. "What's the tallest building in the world?" would bring you a cool looking card carrying the answer and an photo of Burj Khalifa. To top things off, Google's Voice Search assistant will read the answer to you, so you don't even need to look at the screen.
It's not witchcraft this Google Voice Search. It utilizes the company's Knowledge Graph to gather the snippets of information needed to give you a satisfying answer. That's certainly bringing us a step closer to a more advanced virtual personal assistants, but just like the competition, Google's assistant need to go a long way before it becomes useful for daily tasks.
Offline Voice typing and a new smart Keyboard
Voice typing now works offline. To make it happen, Google has baked the voice recognition algorithms needed to make it run into Android itself. Not only does this make Voice typing faster, but also eliminates the need for internet connection.
With Jelly Bean, the Android keyboard's nuts and bolts got updated as well. It now features smarter dictionary algorithms and the more you write, the better it can predict your words as it's learning algorithms let it unveil its full potential.
So for example if frequently write "I am going home, see you in 15 minutes", the dictionary will be able to predict words and phrases like "home" and "15 minutes". It resembles Swiftkey's smart dictionary system, but only time will tell if it performs as well.
Truly HD contact photos
Ice Cream Sandwich introduced the updated People app, which boasted a cool looking large contact pictures. They looked great on the Google demos, but once users got to test them, they weren't quite as impressive.
That's because Google was using the contact photos from Gmail, which were limited top 96x96 pixels. Put simply, they looked terrible on the HD display of the Galaxy Nexus.
Fortunately, Google got around to fixing them in Jelly Bean by increasing the maximum possible resolution to 720x720 pixels. This may not sound like much, but it was a major eye sore that accompanied every call.
Updated Camera app
The camera app is a bit nicer to look at and somewhat more intuitive in Jelly Bean. When you snap a photo, it flies sideways from the viewfinder and into the gallery. You can then do a finger swipe to follow it and review your recently captured images.
Yes it works just like on Windows Phone, but there's some extra functionality. Once you are in the gallery, you can pinch-zoom out and view your photos in a card-like interface, which lets you delete some of them with simple upwards swipes. As cool and easy as it gets.
And don't worry - if you delete something by mistake, you can always bring it back by tapping the undo button.
Google Maps offline
Google unveiled its updated Maps app at a special event and now all the goodies are available to Android users as well. A new addition is the inclusion of a 'Save for offline view' button, allowing you to precache whole cities into your phone. Previously, it was only available as a Labs feature.
Mind you the feature is available in select regions only so your mileage with it will vary depending where you are in the world.
Android Beam shares more
The Android Beam service which came along with Android ICS allowed users to share small bits of information through NFC. Contacts, links, calendar events and addresses could be shared via NFC, but now Jelly Bean brings support for even more content.
By leveraging on the Bluetooth connectivity, which virtually every Android smartphone has, Jelly Bean allows you to share photos and videos with a simple NFC-enabled tap. You can even use Android Beam to pair with Bluetooth devices (via NFC) like speakers, headsets and other gadgets.
Conclusion
After spending a day with it, we feel Jelly Bean is exactly what its version number suggests - a significant update to ICS, but by far not the largest one Android has seen.
Jelly Bean smooths things up, cleans up a lot of bugs, brings a bit of cool new functionality here and there, but doesn't make you scratch your head and feel lost. It's enough to make the ICS users happy with the update, without giving JB owners too many boasting rights.
Google's Voice search and Now service look cool for now, but have yet to prove themselves as the useful companions Google says they are. We are far from convinced that those virtual assistants are worth the effort going into their development, but with all the big players so keen to invest in them, there might be something about them after all.
More importantly, Jelly Bean finally gives Android the smooth feeling of its rivaling platforms. Even on moderately powerful hardware such as the one on the Samsung Galaxy Nexus, Android now has much smoother and faster animations and a bit more fluid navigation.
In a way Google felt so comfortable about Android's lead in functionality that it thought, it might ease off the gas a bit and focus on optimizations for a while. With the platform pretty mature as it is, now seems like as good a time as any to fix those remaining performance issues.
The only thing seemingly missing now is a cure for the fragmentation issue, which is still keeping some developers away from the platform. A little over than 9 months ago, Google unveiled Ice Cream Sandwich and now as it's successor came to live Android 4.0 is powering just over 7% percent of all Android devices out there.
We'll now probably be treated to several months of rumors and contradicting statements from Google's partners before any updates actually make it to the market. We are still hoping, though that the step from ICS to Jelly Bean will be an easier one to make and Android 4.1 won't share the fate of its predecessor - becoming obsolete before even becoming the second most popular Android release.
