What is Android
Android is an operating system for mobile devices that runs on the Linux kernel 
and was developed by Google. It allows software developers to write code using 
the Java programming language. Android is primarily designed for touch-screen 
devices such as smartphones and tablets, with different user interfaces for 
televisions (Android TV), cars (Android Auto), and wearables (Android Wear). 
However, Android is not the same on all devices (Samsung's Android differs from 
LG's, Sony's, and even Google's).
Applications on Android
By mastering Android application programming, we can create various types of 
applications that can bring us not only enjoyment but also financial benefits. 
All that is needed is an innovative idea, for example, an app for finding taxis 
or apps for sharing photos.

Advantages
A key advantage of developing apps for Android devices is that it is relatively 
simple and easy to get started. Unlike developing apps for the iOS operating 
system, which requires a Mac computer, Android apps can be created on any 
computer system. Additionally, the educational materials provided by Android are 
well-organized and well-studied.
