Android Jelly Bean
Android Jelly Bean (Android 4.1, 4.2, 4.3) is the codename given to the tenth version of the Android mobile operating system developed by Google, spanning three major point releases (versions 4.1 through 4.3.1). Among the devices that were launched with Android 4.1 to 4.3 already installed are the Nexus 7 (2012), Nexus 4, Nexus 10, and Nexus 7 (2013).
The first of these three releases, 4.1, was unveiled at Google's I/O developer conference in May 2012. It focused on performance improvements designed to give the operating system a smoother and more responsive feel, as well as improvements to the notification system that allow for expandable notifications with action buttons, and other internal changes. Two more releases were made under the Jelly Bean name in October 2012 and July 2013, respectively, including 4.2—which included further optimizations, multi-user support for tablets, lock screen widgets, quick settings, and screensavers, and 4.3—which contained further improvements and updates to the underlying Android platform. The first device with Android Jelly Bean was the 2012 Nexus 7.
As of January 2025[update], 0.04% of Android devices run Jelly Bean. In July 2021, Google announced that Google Play Services would no longer support Jelly Bean after August of that year.
Android 4.1 Jelly Bean was first unveiled at the Google I/O developer conference on June 27, 2012, with a focus on "delightful" improvements to the platform's user interface, along with improvements to Google's search experience on the platform (such as Knowledge Graph integration, and the then-new digital assistant Google Now), the unveiling of the Asus-produced Nexus 7 tablet, and the unveiling of the Nexus Q media player.
For Jelly Bean, work was made on optimizing the operating system's visual performance and responsiveness through a series of changes referred to as "Project Butter": graphical output is now triple buffered, vsync is used across all drawing operations, and the CPU is brought to full power when touch input is detected—preventing the lag associated with inputs made while the processor is in a low-power state. These changes allow the operating system to run at a full 60 frames per second on capable hardware.
Following 4.1, two more Android releases were made under the Jelly Bean codename; both of these releases focused primarily on performance improvements and changes to the Android platform itself, and contained relatively few user-facing changes. Alongside Android 4.1, Google also began to decouple APIs for its services on Android into a new system-level component known as Google Play Services, serviced through the Google Play Store. This allows the addition of certain forms of functionality without having to distribute an upgrade to the operating system itself, addressing the infamous "fragmentation" problems experienced by the Android ecosystem.
Attendees of the Google I/O conference were given Nexus 7 tablets pre-loaded with Android 4.1, and Galaxy Nexus smartphones which could be upgraded to 4.1. Google announced an intent to release 4.1 updates for existing Nexus devices and the Motorola Xoom tablet by mid-July. The Android 4.1 upgrade was released to the general public for GSM Galaxy Nexus models on July 10, 2012. In late 2012, following the official release of Jelly Bean, a number of third-party Android OEMs began to prepare and distribute updates to 4.1 for their existing smartphones and tablets, including devices from Acer, HTC, LG, Motorola, Samsung, Sony, and Toshiba. In August 2012, nightly builds of the aftermarket firmware CyanogenMod based on 4.1 (branded as CyanogenMod 10) began to be released for selected devices, including some Nexus devices (the Nexus S and Galaxy Nexus), the Samsung Galaxy S, Galaxy S II, Galaxy Tab 2 7.0, Motorola Xoom, and Asus Transformer.
On October 29, 2012, Google unveiled Android 4.2, dubbed "a sweeter tasting Jelly Bean", alongside its accompanying launch devices, the Nexus 4 and Nexus 10. Firmware updates for the Nexus 7 and Galaxy Nexus were released in November 2012. Android 4.3 was subsequently released on July 24, 2013, via firmware updates to the Galaxy Nexus, 2012 Nexus 7, Nexus 4, and Nexus 10.
