Google has gone all in with Jelly Bean, they kicked off their feature list with Project Butter which is mean to give Jelly Bean a “buttery smooth.” experience. The Android team accomplished this by bumping up Jelly Bean’s framerate to 60 FPS, and implemented vsync and triple buffering to tighten up the experience. Developers also have access to a new tool called systrace in the Jelly Bean SDK that displays what the rendering engine is up to.
Text input has also been improved, because now you no longer need to have a solid network connection, this means you can voice type with no internet connection.
The blind are going to be flocking to Jelly Bean with a newly-added Gesture Mode allows blind users to navigate their devices with gestures, and there is even support for external braille devices.
Androidcan now share video via NFC and pair with an NFC-enabled Bluetooth device just by tapping it.
Notifications have also gotten a bit of a facelift, users can now return phone calls from within notifications and you can now view multiple emails without having to jump into a separate app. Apps now have greater access to the notification shade as they can be expanded by dragging down with two fingers.
This all sounds great but when can we get it? Google will begin their over-the-air updates to theand Motorola in the middle of July, and SDK is available today!
