Android has been around for about 15 years as a mobile operating system. It is largely used as the basic operating system of phones and tablets all around the world. Furthermore, other operating systems, such as Chrome OS and Windows 11, natively accept Android applications.
Google controls this mobile operating system. The technology, however, is open source, making it freely available to anybody, even for commercial usage. This distinguishes it from Apple’s iOS, MacOS, and Microsoft’s Windows, all of which are closed-source systems.

Android relies on Linux to manage device drivers, memory, processes, and networking. However, you will never be programming directly to this layer.
The Android native libraries are found on the next level. Internally, they’re all written in C/C++, and you’ll be accessing them via Java interfaces. The Surface Manager (for compositing windows), 2D and 3D graphics, Media codecs (MPEG-4, H.264, MP3, etc.), the SQL database (SQLite), and a native web browser engine are all included in layer (Web Kit).
The Application Framework layer follows, which supports programme life cycles and a common “back-end” for user navigation. Android includes a significant part of the Java 5 Standard Edition packages, such as Collections, I/O, and so on. Dalvik uses dex files, which are smaller and more efficient than class files.
The Platform layer is where your code coexists with Google’s built-in programmed like the Phone and Web Browser. If you like, you may even instruct Android to have your application replace the regular applications.
