  • Android is a mobile operating system designed for smartphones and other mobile devices. The OS is based on the Linux kernel, but it has since added proprietary software to the mix.
  • The platform consists of an operating system, middleware, applications, and also comprises several libraries. Some of these libraries are open-source software and others are closed-source code created by Google.
  • The APIs that Android developers use to build apps refer to different components in the Android SDK including activity classes (aka activity), broadcast receivers, content providers, services, and threading classes.

The term component in Android development can be defined as a class that encapsulates an independent function of the application.

The following are some examples of components in Android development:

  • Activities: A component which is responsible for displaying the screen and handling user interactions. They are intended to present data primarily to the user and offer options to manipulate it.
  • Services: Components that run outside of their own process and are not visible to other components, but perform their tasks without affecting other components or processes

  • The Android platform has an amazing range of different types of apps that are developed for a huge variety of purposes.
  • Now, let’s talk about the components of an Android application. When you think about it, there are actually only three different types of components. The first is the main activity - a single screen where all the other activities live. The next is the layout - which defines how your app will look on your device's screen. And finally, there is a layout XML file - which defines how your layout will look on various sizes and form factors (such as phones or tablets).
  • The multi-activity paradigm in Android allowed developers to create a single activity that can be used in several different ways by switching between different flows that are displayed in different layouts.

  • There are many ways to create a component in Android Studio. This article will cover the most common ways of creating components.
  • After reading this article, you should be able to create a new Android Studio project and add your own custom components First, let's go over what makes a component in Android Studio different from other types of code in Android Studio.
  • Components are functions that extend the functionality of the Activity class, but do not inherit from it like other classes such as Activities, Fragments and Services would. A Component is usually grouped into libraries so an app can use them as needed across multiple apps or even multiple projects within one app.

  • The component you want to create is a part of the user experience. It has a title and icon that the user can click on, and it’s one of the first things they see when they visit your app. Creating a new component is an easy process with React Native's create-component lifecycle method.
  • You can also use this lifecycle method to add/remove props from your existing components as well as selectively render them for different screens in your apps. For example, if you had two components that rendered differently on different screens, you could use this method to only render one of them depending on which screen the app was currently rendering on.
