The first of these three, 4.1, was unveiled at Google's developer conference in June 2012, focusing on performance improvements designed to give the operating system a smoother and more responsive feel, improvements to the notification system allowing 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, widgets, quick settings, and screen savers, and 4.3—contained further improvements and updates to the underlying Android platform.
The x86 Android* 4.1.2 (Jelly Bean) emulator system image enables you to run an emulation of Android on your development machine. In combination with the Android SDK, you can test your Android applications on a virtual Android device based on Intel Architecture.
Jelly Bean versions are no longer supported. As of July 2018, statistics issued by Google indicate that 3.6% of all Android devices accessing Google Play run Jelly Bean. However, this does not mean that a greater number of devices running Jelly Bean aren't out there, sideloading apps rather than getting them from Google Play due to the lack of support for the last version of Android to have truly expandable memory (Expandable memory was broken on KitKat and Lollipop, then tied to the device on Marshmallow). Contents. Development Android 4.1 Jelly Bean was first unveiled at the developer conference on June 27, 2012, with a focus on 'delightful' improvements to the platform's user interface, along with improvements to Google's experience on the platform (such as integration, and the new digital assistant ), the unveiling of the -produced, and the unveiling of the 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, 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 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 for its services on Android into a new system-level component known as, serviced through.
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. Release Attendees of the Google I/O conference were given Nexus 7 tablets pre-loaded with Android 4.1, and smartphones which could be upgraded to 4.1. Google announced an intent to release 4.1 updates for existing Nexus devices and the 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 began to prepare and distribute updates to 4.1 for their existing smartphones and tablets, including devices from,. In August 2012, of the aftermarket firmware based on 4.1 (branded as CyanogenMod 10) began to be released for selected devices, including Nexus devices, the, and,.
On October 29, 2012, Google unveiled Android 4.2, dubbed 'a sweeter tasting Jelly Bean', alongside its accompanying launch devices, the. 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. Features User experience.
The notification area, showing expandable notifications, and the 'quick settings' button. Visually, Jelly Bean's interface reflects a refinement of the 'Holo' appearance introduced by Android 4.0.
The default home screen of Jelly Bean received new features, such as the ability for other shortcuts and widgets on a home screen page to re-arrange themselves to fit an item being moved or resized. The notification system was also improved with the addition of 'expandable' and 'actionable' notifications; individual notifications can now display additional content or action buttons (such as 'Call back' or 'Message' on a missed call), accessible by dragging open the notification with a two finger gesture. Notifications can also be disabled individually per-app. Android 4.2 added additional features to the user interface; the can be swiped to the left to display widget pages, and swiped to the right to go to the camera. A pane of 'quick settings' toggles (a feature often seen in OEM Android skins) was also added to the notification area—accessible by either swiping down with two fingers on phones, swiping down from the top-right edge of the screen on tablets, or pressing a button on the top-right corner of the notifications pane. The previous 'Browser' application was officially deprecated on 4.2 in favor of.
4.2 also adds gesture typing on the keyboard, a redesigned clock app, and a new system known as 'Daydreams'. On tablets, Android 4.2 also supports multiple users. 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 optimized 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 placed in the bottom-left of a bar along the bottom of the screen, with the clock and notification area in the bottom-right.
Platform For developers, 4.1 also added new accessibility APIs, expanded language support with support and user-supplied keymaps, support for managing external input devices (such as ), support for multichannel, USB, and audio, a new media routing API, low-level access to hardware and software audio and video codecs, and DNS-based service discovery and pre-associated service discovery for Wi-Fi. Can now also be used to initiate file transfers through. Android 4.2 added a rewritten, changing from the previous stack ( originated by ) to a rewritten open source stack called. The new stack, initially considered 'immature', promised several forward-looking benefits, including improved support for multiple displays, support for, native support, updated developer tools, further accessibility improvements such as zooming gestures, and a number of internal security improvements such as always-on support and app verification. A new stack was added at the same time. Android 4.3 consisted of further low-level changes, including and support, 3.0, new (DRM) APIs, the ability for apps to read notifications, a encoder, and other improvements. Android 4.3 also included a hidden privacy feature known as 'App ops', which allowed users to individually deny permissions to apps.
However, the feature was later removed on Android 4.4.2; a Google spokesperson stated that the feature was experimental and could prevent certain apps from functioning correctly if used in certain ways. See also. References. Retrieved August 1, 2018. Ars Technica. Retrieved July 2, 2014.
