Android Jelly Bean was released on June 2012 as a successor to Android Ice Cream Sandwich.

As a matter of fact, Jelly Bean versions are no longer supported by Google.

Android Jelly Bean | Features

Android Jelly Bean’s primary design objective is to be faster and smoother than previous versions while providing advanced features.

It’s interaction between different screens is faster than that of its predecessors.

Notable features added to this version include:

  • Improved notifications with more user control
  • Voice recognition, which allows users to dictate email, verbally search for terms, etc.
  • Project Butter, an Android initiative to predict user touchscreen movements and adjust frames for improved response
  • Google Now, which learns and pushes related content to the user
  • Enhanced support for HTML 5
  • Upgrade to JavaScript Engine (V8)

To promote consistency between device classes, Android tablets now use an expanded version of the interface layout and home screen used by phones by default, with centered navigation keys and a status bar across the top.

These changes took effect for small tablets (such as the Nexus 7) on 4.1, and for larger tablets on 4.2. Small tablets on Android are optimize primarily for use in a “portrait” (vertical) orientation, giving apps expanded versions of the layouts used by phones.

When used in a “landscape” (horizontal) orientation, apps adjust themselves into the widescreen-oriented layouts seen on larger tablets.

On large tablets, navigation buttons were previously place in the bottom-left of a bar along the bottom of the screen, with the clock and notification area in the bottom-right.
