A Brief History of the Android Operating System


Google first introduced the revolutionary Android operating system as analternative to Apple’s iOS in late 2008.Since it’s existed, Android has had 12 versions since its humble beginningwith sometimes even more than one release in a year.The constant support from Google developers made the system the top OS withalmost 3 million apps in the Play Store. This helped switch Android appdevelopment from Java to Kotlin and ensured that Android developers werehighly paid and quite in demand on the market.Here I’ve gathered an abridged listing to demonstrate how the operating systemhas been changing and evolving to provide users with advanced functionality.For much of its lifetime, the OS version was designated by a number and acodename. * Android 1.0 to 1.1 – Google’s original mobile OS offered basic capability with integrated apps like Gmail, Maps, Calendar, and YouTube. * Android 1.5 or Cupcake – Released in early 2009, this was the first-named version of the OS. It included an on-screen keyboard and introduced the framework for third-party apps to be run on mobile devices. * Android 2.0-2.1 or Eclair – Version 2.0 added real-time traffic information, voice-guided navigation, and pinch-to-zoom capability to the OS. * Android 2.3 or Gingerbread – The 2010 release of this OS focused on the black and green interface as Android began to develop a distinctive look. * Android 3.0-3.2 or Honeycomb – Released in 2011, this version of the operating system was specifically for tablet devices and introduced on-screen buttons. * Android 4.0 or Ice Cream Sandwich – This was a unified OS for phones and tablets all released in 2011 which featured a holographic appearance and made extensive use of swiping when using the system. * Android 4.4 or Kit-Kat – Late 2013 saw this update which lightened the interface’s color scheme and introduced the world to “OK, Google” support. * Android 5.0-5.1 or Lollipop – Major changes were made with 2014’s upgrade. Google introduced the card-based Material Design standard employed to unify the appearance of items displayed by the OS. * Android 6.0 or Marshmallow – This relatively minor update in 2015 was the beginning of Google’s patterns of relaying a new, numbered version every year. * Android 7.0-7.1 or Nougat – 2016’s entry in the Android OS lexicon added native split-screen mode and launched Google Assistant. * Android 9 or Pie – Google released this last-named version of Android in August of 2018. The most visible updates of this version for users were the large Home and small Back buttons to the user interface and new security features. * Android 10 – is the last live version of OS and we will cover it in more detail below.

Android System Architecture Last Updated: 06-02-2018 The Android softwarestack generally consists of a Linux kernel and a collection of C/C++ librariesthat is exposed through an application framework that provides services, andmanagement of the applications and run time Android system architecturecontains the following components: Figure 1. Android system architecture.Application framework.The application framework is used most often byapplication developers. As a hardware developer, you should be aware ofdeveloper APIs as many map directly to the underlying HAL interfaces and canprovide helpful information about implementing drivers When we talk aboutAndroid architecture, we mean how the Android system has been designed,segmented into layers, and built up to work as a system. Building such acomplex system requires careful structuring to ensure all the components worktogether cohesively. Its architecture ensures that the many componentsfunction as a whole without crashing

The Android Software Stack. Android is structured in the form of a softwarestack comprising applications, an operating system, run-time environment,middleware, services and libraries. This architecture can, perhaps, best berepresented visually as outlined in Figure 9-1 Android architecture is a stackof software components. It is in the form of a software application, operatingsystem, run-time environment, middleware, native libraries and services. It iscategorized into five parts as below: 1. Linux Kerne Architecture Diagram.Here is the Android Architecture Diagram, obtained from here.. See alsoAndroid internals diagram. Basically Android has the following layers:applications (written in java, executing in Dalvik) framework services andlibraries (written mostly in java Android 10 or higher converts selectedsystem components into modules, some of which use the APEX container format(introduced in Android 10) and some of which use the APK format. The modulararchitecture enables system components to be updated with critical bug fixesand other improvements as needed, without affecting lower-level vendorimplementations or higher-level apps and servicesAndroid Architecture Components Part of Android Jetpack. Android architecturecomponents are a collection of libraries that help you design robust,testable, and maintainable apps. Start with classes for managing your UIcomponent lifecycle and handling data persistence Platform Architecture.Android is an open source, Linux-based software stack created for a wide arrayof devices and form factors. The following diagram shows the major componentsof the Android platform. Developers have full access to the same frameworkAPIs that Android system apps use Android Inc. was founded in Palo Alto,California, in October 2003 by Andy Rubin, Rich Miner, Nick Sears, and ChrisWhite. Rubin described the Android project as tremendous potential indeveloping smarter mobile devices that are more aware of its owner’s locationand preferences. The early intentions of the company were to develop anadvanced operating system for digital cameras, and this. Android architectureis a software stack of components to support mobile device needs. Androidsoftware stack contains a Linux Kernel, collection of c/c++ libraries whichare exposed through an application framework services, runtime, andapplication. Following are main components of android architecture those arOur choice is motivated by the fact that, according to market research 49.2%of mobile devices sold worldwide in 2012 have used Android SystemArchitecture. The implemented games are time. The Android software stack asshown in figure 1.1 can be subdivided into five layers: The kernel and low leveltools, native libraries, the Android Runtime, the framework layer and on topof all the applications. Figure 1.1: Android system architecture. Green itemsare written in C/C++, blue items are written in Java and run in the Dalvik VM1. What is Android Architecture? Android is a mobile operating system that hasan open-source framework and is based on Linux which helps us to developadvanced and user-friendly applications. Now, we will start with AndroidArchitecture, it comprises of five levels, which are the Linux kernel,Libraries, Application framework, Android runtime.

If desired, Android Automotive-specific functions are alsodiscussed. The main focus is on the low-level layers, as well as on adaptingand expanding it in order to port it onto your own hardware Unfortunately, asof 2019, Clean Architecture in Android primarily means having some use caseclasses and that’s it. IMHO, it’s very narrow and unfortunate perspective. Forinterested developers, I highly recommend Uncle Bob’s book titled CleanArchitecture which contains much more thorough and consolidated discussion ofwhat goes into clean architecture and Clean Architecture Another Androidrecommendation is to consolidate its architecture using a Dependency Injectionsystem, like Google’s Dagger 2 or using the Service Locator pattern.Architecture Component System Services of Android Operating System A serviceis a compiled piece of code that runs for a long time in the background of anandroid operating system without giving any interface.

In thissegment, Mike gives an overview of the system architectureNow, when we look at the structure of Android as an operating system, youwould understand that it is a compilation of certain software components. Allof these components are segregated into 5 sections and 4 major layers. Tounderstand this architecture, you can take a look at the below-drawn blockdiagram Because Android is a Linux-based operating system, it benefits fromits key security features and hardware drivers. Hardware Abstraction Layer(HAL) HAL is the second layer in the Android architecture. It provides variousinterfaces through which we can access the different hardware of the systemlike (camera, bluetooth, etc,) Under this situation, Android comes out. It isa mobile OS developed by Google. The system is open-sourced based on linux sothat it can be developed by developers. In this thesis, some research are doneon the Android System.
