It's kind of a tradition now for the Android team to create different boot animations for every Android release, and Jelly Bean is definitely no exception. Here's the boot animation from the Nexus 7 which is, as you all should know by now, the first device running Android 4.1:
If you need a refresher, here's the one from ICS, for comparison purposes (for science!):
Well, we now have yet another reason to envy Google I/O attendees - a signed copy of the official Jelly Bean build has just been released on the 'nets, but it seems to only be working on the 'takju' (GSM) Galaxy Nexuses given out at I/O 2012 (or at least those GNs with the IMM30D firmware).
You can grab it for yourself right here, if you're interested in what's inside the 156MB ZIP.
Android has become somewhat infamous for slow (almost unbearably so) updates for users of pretty much any non-Nexus device. In fact, when Jelly Bean was announced earlier today, the first thought on some users' minds was that their handsets haven't even tasted Ice Cream Sandwich yet.
Google is well aware of this issue, though - last year, it made an attempt (albeit a feeble one) to solve the problem with the Android Alliance.
Coinciding with the announcement of Android 4.1 Jelly Bean, Android developers can now pull down a new revision of Android's SDK tools – revision 20, along with a new version of the ADT Plugin, also r20 (which Eclipse users will need to use SDK r20).
The revised SDK tools bring several improvements. One of the notable additions to the SDK tools is System Trace (otherwise known as systrace), a tool (included in Project Butter) that helps monitor system activities, allowing developers to pinpoint graphical rendering or other issues.
Google Now is a feature we've been eagerly anticipating for what seems like forever now. In fact, we've been seeing hints at something like it since 2010. When Apple announced Siri last year, an official counterpart from Google became not only inevitable, but necessary - iOS' speech service provided direct Apple competition to Google's mobile search engine. Today, in one of the most notable announcements at I/O, the Big G made official its answer to Siri: the aforementioned Google Now.
One of the bigger changes we saw in the jump from Gingerbread/Honeycomb to Ice Cream Sandwich was in the camera app. ICS not only brought a streamlined, more subtle design to an app that so badly needed it, but also introduced zero shutter-lag, meaning the time between pressing the shutter release and capturing a photo was pushed down to (almost) zero. In fact in many cases, the time between touch and capture is imperceptible.
Another major enhancement we've just learned about with the announcement of Jelly Bean is called Project Butter. Butter (so named likely due to the colloquialism "smooth as butter") represents a new, more efficient processing framework for Android's latest and greatest iteration, making the OS much faster (allowing animation up to 60fps). Android 4.1 also makes apps more responsive, reducing touch latency and "anticipating where your finger will be at the time of screen refresh."
"How is such an enhancement possible?" I can almost hear you wondering.
"Android has always put you in control when it comes to staying notified and connected. Now you can take action directly from the notifications shade," says Android's updated "What's New" page. Indeed, today's Jelly Bean announcement saw a number of improvements to the already handy notification system we've come to know and love in previous iterations of Android. Not only can the new notifications system display larger, richer notifications, developers can create actionable notification with interactive controls for telephony, music, and more.
Over at Google I/O, the news about Android 4.1 - a.k.a. Jelly Bean, if you haven't heard - just broke.
Update: check out the Jelly Bean video:
The first announcement was Project Butter, a new processing framework for Android that should make it run much, much faster - up to 60fps, in fact. The CPU and graphics will now work together in harmony, with the latter being triple-buffered, meaning things like scrolling and transitions should be noticeably faster.
