Google has released the latest version of their mobile OS, Android 4.2 Jelly Bean to AOSP, and along with the Jelly Bean release, they have also added the factory images for the Google Nexus 4, Nexus 7, and Nexus 10.
The source code for 4.2 is being pushed to AOSP right now. Look for it under the name “android-4.2_r1” once the replication completes. The matching development branch (for CTS contributions) is jb-mr1-dev, and all the changes are merged into the master branch where platform contributions are accepted.
New Features in Android 4.2 Jelly Bean
Android 4.2 Jelly Bean brings a host of new features and improvements to the Android ecosystem. One of the most notable additions is the introduction of the “Photo Sphere” camera feature, which allows users to capture 360-degree panoramic photos. This feature enhances the photography experience by enabling users to create immersive images that can be shared on Google Maps and Google+.
Another significant update is the inclusion of “Gesture Typing” on the keyboard. This feature allows users to type by simply gliding their fingers over the letters, making typing faster and more intuitive. The keyboard also predicts the next word, which can significantly speed up the typing process.
Android 4.2 also introduces multiple user accounts for tablets. This feature is particularly useful for families or shared devices, as it allows each user to have their own personalized space with separate apps, settings, and home screens. This ensures that each user’s data remains private and secure.
Enhanced Performance and Security
Performance improvements are a key focus in Android 4.2 Jelly Bean. The operating system includes “Project Butter,” which aims to make the user interface smoother and more responsive. This is achieved through triple buffering, enhanced vsync timing, and improved touch responsiveness, resulting in a more fluid and enjoyable user experience.
Security has also been enhanced in this release. Android 4.2 includes a feature called “Verify Apps,” which scans apps for malicious behavior before they are installed. This adds an extra layer of protection against malware and ensures that users can download apps with greater confidence.
Additionally, the new “Daydream” feature acts as an interactive screensaver that displays useful information, such as photos, news, and other content, when the device is idle or docked. This feature not only adds a touch of personalization but also keeps users informed even when they are not actively using their devices.
