A Step-By-Step Guide To Android Programming
Like other app development platforms, Android also requires developers to achieve certain skills. When the developers have the right tools and techniques, it will become easier to create Android apps. However, here is a step-by-step and detailed Android Development Roadmap that can help in become an Android developer.
1. Begin With Learning a Programming Language
Android programming or app development requires an app developer to develop technical skills and learn about different programming languages. It will be better for developers to learn about Java, SQL- Structured Query Language, Kotlin, and XML- Extensible Markup Language. Java is one of the two crucial Android programming languages. Apart from learning about Java Syntax and form, getting familiarized with classes, variables, static methods, inheritance, loops, and more will be better.
On the other hand, Kotlin is another primary programming language every Android developer needs to learn. Developed by Google, this is a replacement for Java language. With many useful features, Kotlin is designed to simplify the coding process. It can lower the risks of app crashes and coding errors. By learning Kotlin, the developer can also use Kotlin code on Java.
This programming language can be used to develop modern apps keeping in mind better performance and enhanced features. While learning about Kotlin, it is advisable to focus on OOP-Object-Oriented Programming, algorithms and data structures, and Syntax and idioms. Learning SQL will help the developers to organize databases effectively within the apps. Furthermore, learning GIT programming will allow Android developers to develop and use multiple repositories.
Before deepening Android programming, developers should develop their skills in these languages.
2. Understand the Android Application Lifecycle
Developers who have already developed web or desktop applications need to understand that developing apps for mobile phones is different. In the case of a desktop application, the Operating System will manage the application and its priorities. On the other hand, in Android, the developers can code the application to handle various external events.
For example, deciding what the app will do if the device receives a message or call while playing a game. The app needs to be designed in such a way that it can interact seamlessly with other applications. With a better understanding of the Android application lifecycle, one can build an app that will play nicely with other apps to create the best user experience.
3. Learn and Understand the Basics
Another major step in the Android Development Roadmap is understanding the basics. There are different components in the Android development platform. Before one can begin developing an app, it is crucial to know about those components and how they work to develop a functional Android app.
Those who are wondering how to learn Android development for free can join free online training courses that will help them familiarize themselves with the basics. Besides, they can also learn about standardized security practices, app configuration changes, and more.
After obtaining knowledge about the Android platform’s elements, it will be easier to design and develop an app with different tools. Developers can also visit the official Android development website to get other ideas and learn about the technologies related to Android development, suggestions, and more. Even though it is not a mandatory step, it can help get a better insight into development concepts.
4. Learn About Various Android Tools
All beginner Android developers must know about some important Android development tools. One can’t move forward with Android programming without understanding Android Studio. Developed in 2013 by Google, it is the official IDE- Integrated Development Environment.
When it comes to coding, the IDE can offer some valuable functionalities like Syntax highlighting, building, auto-completing, and more. It can also complete the names of fields, methods, keywords, and classes. Some other IDEs that can be used for Android programming are NetBeans, Eclipse, IntelliJ IDEA, and Komodo.
However, Android Studio is free to use and is a grade-based build system. It supports a wide range of testing tools and frameworks. Furthermore, it has a layout editor and supports C++. With this, android developers can reduce the setup time and standardize the app development process.
Performance will always be a significant consideration when working on a mobile and web project. And using FlowUp, developers can quickly check their Android app performance. It is a SaaS soliton. It provides the developer with an easy-to-use dashboard to review the critical metrics for their apps, such as disk usage, bandwidth, CPU, and more.
Another primary tool an Android developer can get help from is the Git tool- A VCS- Version Control System. This tool lets the developers keep track of changes in the app’s codebase. They can also compare, merge, and analyze multiple changes and restore the older versions when required. By learning how to use the Git tool, developers can easily handle small as well as large-sized projects.
It will also be helpful if developers learn about Gradle. It helps in developing, compiling, and publishing apps.
5. Begin With a Small Project
After a basic understanding of common tools, programming languages, and platforms, beginners can develop their first app. Begin with a small app and progress slowly. While using an open-source platform, they can also interact with the community and other developers to enhance their skills and find more opportunities. Beginners should pick a topic that they like.
One can easily find many free Android programming projects on GitHub. They can choose from different projects, like review projects, bug fixing, etc. Test and debug carefully to ensure the app is ready to work in different situations. App testing can be done using the emulator.
