What is Android Development?

Android is a computing platform developed by Google based on the Linux operating system (OS).

Android development is a software engineering branch that produces applications exclusively for android-based devices. 

The open-source android platform has risen to become the most widely used operating system in the world in just ten years. The android operating system now has more users than any other mobile operating system in the market.

Android developers labor diligently to produce apps that run smoothly and enable the software to function and execute a variety of programming languages and computational operations.

The first commercial version of android launched in 2008 as a mobile phone platform, and today, countless companies and brands rely on android applications to expand their reach, ingenuity, and popularity.

Basic Fundamentals Of Android Development

The backbone of android is composed of app components. 

Every component has a unique function and life cycle, from the app's launch to its completion.

These are the four main parts of an app that all android developers should know:

Activities: 

It deals with the user interface and screen interactions. It commences with the application's launch. The term "MainActivity" refers to the one activity that is constantly present.

Services: 

The service's primary goal is to keep the program running continuously without interfering with user interaction. Services are the tasks the app completes in the background.

Broadcast Receivers: 

A broadcast answers messages sent by the system or by other applications.

Content Provider: 

This tool is used to move data from one application to another. This class provides a collection of APIs (Application Programming Interfaces) that let other programs execute transactions.

10 Must-Have Hard Skills For Every Android Developer

Mobile apps have progressively permeated several aspects of contemporary lifestyle and economic sectors.

Recent estimates indicate that android has a staggering 74.3% of the worldwide mobile OS market, making it the undisputed market leader.

This critical advancement for the android platform shows the surge in demand for creating cutting-edge applications and the necessity for competent and effective android developers.

Here are the top 10 essential skills that an excellent android developer must possess:

1. Knowledge of Java and Kotlin

The two official programming languages for android applications are Java and Kotlin. Fluency in at least one of the two languages is the most critical criterion an android developer needs to kick-start their career in the development industry.

2. XML fundamentals

In android development, Extensible Markup Language (XML) defines the design layouts (user interface). Android developers can now design layout components like buttons, text views, headers, and more with XML. A developer needs to comprehend the fundamental tenets of XML.

3. SQL knowledge 

To store databases within the apps and arrange user data, the android developers must understand SQL. To manage the data, they must integrate the software with a database.

4. Android Testing Fundamentals

The process of android app development includes testing as a crucial step. It is vital to examine every class and module while developing the app. Junit, Mockito, Espresso, and other testing libraries are some of the most frequently used ones.

5. Knowledge of Android Studio

The integrated development environment (IDK) for the android OS is called the android Studio. Developers can easily construct completely functional programs thanks to the problem diagnosis, memory monitoring, and automatic recommendation features it offers.

6. Concepts of Android SDK 

Android SDK is a collection of development tools. It is used to create mobile apps. It includes Libraries, a debugger, documentation, and more. The knowledge of the Android SDK aids in measuring the proficiency of an android developer.

7. Design of Material

A thorough guide for visual, motion, and interaction design is included in the design language called "Material Design." To create distinctive mobile applications, an android developer must adhere to the guidelines specifications and use creative elements and architectural features from its support library.

8. Understanding The Backend Features

The code that powers the applications is all found in the backend development. It enables android developers to add features like real-time communications, cloud backup of user data, and more.

9. Concept of Android Security 

The most crucial component of mobile applications is security. To protect the android apps, one must utilize a variety of software libraries. Therefore, understanding how to increase the security of your application is crucial.

10. GIT expertise

Git's most fundamental and vital feature is its ability to let teams simultaneously merge code into a single project. This way, android developers can work on more significant projects and tackle complex challenges efficiently.

Responsibilities Of An Android Developer

The android developer is responsible for several tasks, including designing the app and debugging it once it is released. Android developers must consider several factors when developing an app to make it engaging and user-friendly. 

An android developer is responsible for the following things:

Creating the UI and functionality of An App:

Designing and constructing the app's functionality is the primary responsibility of any android developer. This entails creating a well-thought-out design, developing clean code, considering potential defects, and trying to prevent them.

Managing APIs and databases:

An android developer frequently has to deal with external resources like databases and different APIs. This implies that the developer should possess the necessary expertise to work with third-party codes.

Unit testing:

Module testing is the other name for unit testing, which is often a crucial step in software development.

Bug fixing:

Unfortunately, bugs are an inevitable part of developing android apps. It is the responsibility of the developer to detect some of these errors in the code and fix them for quality assurance.

Keeping Up-to-Date with Latest Technologies:

In today's high-tech world, it is not feasible to be a skilled developer without giving education the attention it deserves. An android developer should constantly learn new things and expand their knowledge.

Tools Required For Android Development

Android is one of the most popular operating systems in the world. Thus, there is an evident need for android applications. 

The premium tools that an android developer can use are:
