Introduction
Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets. Android was unveiled in 2007, with the first commercial Android device launched in 2008. Today it is the world’s most popular and widely used smartphone operating system.
This research paper will provide an in-depth look at the Android operating system, its history, key features and components, different versions, market share, and impact. It will analyze how Android emerged as a dominant force in the mobile industry and disrupted the market previously dominated by proprietary alternatives like Symbian and BlackBerry OS. The paper will also look at ongoing developments and the future of Android.
History of Android
Android Inc was founded in Palo Alto, California in 2003 by Andy Rubin, Rich Miner, Nick Sears, and Chris White. In July 2005, Google acquired Android Inc. for an undisclosed amount. At the time of acquisition, Android’s team consisted of just a few engineers and executives.
In November 2007, the Open Handset Alliance, a consortium of technology companies including Google, device manufacturers such as HTC, Sony, and Samsung, wireless carriers like Sprint and T-Mobile, and chipset makers like Qualcomm and Intel, was unveiled to develop open standards for mobile devices.
The first commercially available smartphone running Android was the HTC Dream, also known as T-Mobile G1, launched by T-Mobile in September 2008. Within a few years, Android grew to become the dominant smartphone platform in many markets around the world. As of Q4 2020, Android powered around 70% of worldwide smartphones, according to research firm IDC.
Key Features and Components
Android is an open source operating system based on the Linux kernel. Its key features include:
Open source & customizable: Android is derived from Linux and is open source. Manufacturers and developers can modify the OS and build their own customized Android versions.
App Store (Google Play): The Google Play Store provides access to millions of third-party applications and games that expand Android’s functionality.
Multitasking: Android supports true multitasking and allows users to run multiple apps simultaneously.
Cloud integration: Features like Google Photos, Gmail, Drive offer cloud storage, sync and access across devices.
Voice control: Capabilities like Google Assistant allow interacting with Android devices via voice commands.

Some important components of the Android software stack include:
Linux kernel: Modified Linux kernel for low-level system functionality like memory and process management.
Libraries: Reusable libraries like WebKit and SQLite are used by Android apps.
Android runtime: Provides a Java virtual machine and class library for executing Java bytecode.
App framework: Manages activities, services, intents that allow apps to work together seamlessly.
Applications: Apps developed using Android SDK & built-in APIs for notifications, location etc.

Market Share and Impact
According to IDC estimates, in Q4 2020 Android accounted for around 69.7% of worldwide smartphone shipments, giving it a clear leadership over competitors:
iOS – 29.2%
Others (including Harmony, Windows) – 1.2%
Some key factors contributing to Android’s dominance include:
Open licensing model enabling lower-cost devices from numerous OEMs
Large app store catalog and third-party app developer support
Faster hardware innovation giving Android devices specs parity and sometimes edge over iOS
First-mover advantage in emerging markets like India, Africa, Latin America
Free & open source nature allowing optimized localized variants for specific regions
While Android dominates globally in terms of shipments, iOS continues to account for a higher share of Operating System revenues due to its users spending more on apps and services. The disruption caused by Android made open mobile platforms the industry standard, benefitting users, developers and spurring innovation.
Future Outlook for Android
In the coming years, Android will continue extending its strengths in versatility and selection through:
Edge computing and 5G-enabled new AR/VR use cases like cloud gaming on mobile
Deeper integration with automotive infotainment and connected car functionality
New health/fitness tracking features through Wear OS and other wearables
AI capabilities enhancing device/app performance through machine learning algorithms
Rollout of Android features like folding screens and enhanced security updates
Project Mainline allowing seamless updates of OS components like media codecs
Migration towards an open platform combining the best of Android and Chrome OS
While iOS may continue dominating premium markets, Android’s broad appeal across device segments, regions and price points will keep it as the most ubiquitous mobile OS worldwide. Its open licensing model and support from a large ecosystem means Android is well poised for future growth across new form factors and mobile-powered industries.
Conclusion
Android has emerged as the dominant smartphone platform globally, disrupting the market formerly led by proprietary alternatives. Its open licensing model, vast app catalog, regular feature updates and support from top OEMs have enabled Android to proliferate across diverse user segments and geographic regions. Android’s influence continues extending to new mobile technologies and related industries. As mobile devices remain indispensable computing platforms worldwide, Android is well positioned to lead this landscape over the coming years.
