Crack open the candy jar – here’s a breakdown of the most important features in Jelly Bean:
1. Smart Widgets, as Google explains,
“can automatically resize, based on where the user drops them on the home screen, the size to which the user expands them, and the amount of room available on the home screen. New App Widget APIs let you take advantage of this to optimize your app widget content as the size of widgets changes.”
“makes it easier to share images, videos, or other payloads by leveraging Bluetooth for the data transfer. When the user triggers a transfer, Android Beam hands over from NFC to Bluetooth, making it really easy to manage the transfer of a file from one device to another.”
4. Google explained their new Smart app updates:
“Smart app updates is a new feature of Google Play that introduces a better way of delivering app updates to devices. When developers publish an update, Google Play now delivers only the bits that have changed to devices, rather than the entire APK. This makes the updates much lighter-weight in most cases, so they are faster to download, save the device’s battery, and conserve bandwidth usage on users’ mobile data plan. On average, a smart app update is about 1/3 the size of a full APK update.”
“Android 4.1 brings a major update to the Android notifications framework. Apps can now display larger, richer notifications to users that can be expanded and collapsed with a pinch. Notifications support new types of content, including photos, have configurable priority, and can even include multiple actions.”
7. Project Butter is meant to make the experience with Jelly Bean smooth like butter. The Android team was able to do this by “bumping up Jelly Bean’s framerate to 60 FPS, and implemented vsync and triple buffering to tighten up the experience”, Chris Velazco at techcrunch.com explains.
