What is Android?
Android is a widely-used open-source operating system designed primarily for mobile devices, developed by Google. It provides a flexible and customizable platform for smartphones, tablets, smartwatches, and other devices, allowing manufacturers to create a diverse range of products. Android offers a user-friendly interface, a vast ecosystem of applications available through the Google Play Store, and seamless integration with Google services like Gmail, Google Maps, and Google Assistant.
It is known for its versatility, supporting a wide variety of hardware configurations and device types. Android has undergone numerous iterations and updates, each introducing new features, enhanced security, and improved performance. Its open-source nature has also led to a vibrant developer community, contributing to its constant evolution and innovation, making it a dominant force in the world of mobile operating systems.
History of Android
Android, the world’s most widely used mobile operating system, has a rich history that began in 2003 when it was founded by Andy Rubin, Rich Miner, Nick Sears, and Chris White. Google acquired Android Inc. in 2005, and in 2007, they unveiled the Open Handset Alliance, a consortium of tech companies committed to developing open standards for mobile devices. The first commercially available Android device, the HTC Dream (also known as the T-Mobile G1), was released in 2008, running Android 1.0.

What is API level
API level, often referred to as “Android API level” or “API version,” is a term used in the context of the Android operating system. It is a numerical value assigned to each version of the It platform to represent the set of features, functions, and capabilities available to developers when creating Android apps. Understanding API levels is essential for Android developers because it helps them ensure that their apps are compatible with a wide range of It devices and versions.
Here’s a Detailed Explanation of API Levels:
- Android Version: Each new version of the Android operating system is associated with a specific API level. For example, Android 10 is associated with API level 29, Android 11 with API level 30, Android 12 with API level 31, and so on.
- API Compatibility: The API level defines the version of the Android application framework that is available to developers. This includes classes, methods, and other programming interfaces that developers can use to build their apps. The API level also specifies which features and hardware capabilities are supported.
- Backward Compatibility: Android strives to maintain backward compatibility. This means that apps developed for older API levels should continue to work on newer versions of Android. However, apps developed for newer API levels may not work correctly on older Android versions, as they might rely on features or improvements introduced in later versions.

- Target API Level: When developers create Android apps, they can specify a “target API level” in their code. This tells the Android system which API level the app was designed for. It helps ensure that the app runs correctly and takes advantage of the features available in that specific Android version.
- Minimum API Level: Developers can also set a “minimum API level” for their apps, which specifies the minimum Android version required to run the app. Apps with higher minimum API levels won’t be installable on devices running older Android versions.
- API Changes: Each new It version introduces changes and improvements to the API. These changes can include bug fixes, security enhancements, and new features. Developers need to review the documentation and adapt their apps to leverage these changes effectively.
- Testing and Compatibility: Developers often need to test their apps on devices with different API levels to ensure that they function correctly and provide a consistent user experience across a wide range of Android devices.
