What's new in Android 4.4 KitKat (API level 19)

Google announced Android 4.4 KitKat, internally known as Project Svelte, on 3 September 2013. The release had long been expected to be numbered 5.0 and called 'Key Lime Pie'. KitKat debuted on Google's Nexus 5, and has been optimised to run on a greater range of devices, having 512 MB of RAM as a recommended minimum.

What's new in Android 4.3 Jelly Bean (API level 18)

Google released Jelly Bean 4.3 under the slogan "An even sweeter Jelly Bean" on 24 July 2013 during an event in San Francisco called "Breakfast with Sundar Pichai". Most Nexus devices received the update within a week, although the 2nd generation Nexus 7 tablet was the first device to officially ship with it. A minor bugfixing update was released on 22 August 2013.

Security and privacy

Android applications run in a sandbox, an isolated area of the system that does not have access to the rest of the system's resources, unless access permissions are explicitly granted by the user when the application is installed. Before installing an application, the Play Store displays all required permissions: a game may need to enable vibration or save data to an SD card, for example, but should not need to read SMS messages or access the phonebook. After reviewing these permissions, the user can choose to accept or refuse them, installing the application only if they accept.

Update schedule

Google provides major updates, incremental in nature, to Android every six to nine months, which most devices are capable of receiving over the air. The latest major update is Android 4.4 KitKat.

Applications in Android

Android has a growing selection of third party applications, which can be acquired by users either through an app store such as Google Play or the Amazon Appstore, or by downloading and installing the application's APK file from a third-party site. The Play Store application allows users to browse, download and update apps published by Google and third-party developers, and is pre-installed on devices that comply with Google's compatibility requirements.

Android. What is it?

Android is an operating system based on the Linux kernel, and designed primarily for touchscreen mobile devices such as smartphones and tablet computers. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first Android phone (HTC Dream) was sold in October 2008.
