Posted on

Writing Java Apps For Android – Play Store, the official Android app store, now has 3 million Android users. More than 80 percent of smartphones in the world run on Android. These big numbers have a clear message hidden inside – Android app development would accelerate your career to new heights.

Besides finding well-paying jobs, becoming an Android app developer can unleash your creativity and solve practical problems faced by Android users around the world.

Writing Java Apps For Android

Learning Java is important in Android application development. I have been a Java developer for years and in this article I share a program that will help you learn it in a structured yet fun way.

The Simplest Android App: Hello World

Being a successful Android developer requires knowledge of different areas of knowledge. Your app strategy can be best executed if you learn everything steadily, taking it one step at a time so you don’t get overwhelmed. I recommend the following roadmap, followed by more practice to use your time effectively.

These are the basics you should learn before you start developing Android apps. Focus on project-based learning so you can break your project into modules and write usable code.

Libraries are great time savers. They allow you to call a pre-written set of commands and use frequently used functions without writing them from scratch.

Testing libraries like JUnit and PowerMock Mockito saves you writing code snippets to test your project. This is especially recommended for test-driven development (TDD) where creating tests before writing the application code will speed up development. You will use Java test libraries throughout your career and I recommend that you familiarize yourself with them first.

Android design tool. It’s the only constant in your Android app development journey, since you’re likely to use many programming languages ​​and IDEs in your work.

Once you’ve written your Java code to build an Android app, you need a way to run it on Android devices and use the full capabilities of the Android operating system. This is where the SDK comes in – it’s a complete package of scripts, libraries, code samples and routines that you can integrate into your application.

The SDK also has Android emulators, which you can run to see how your code would work on a real Android device.

You will need to be able to work with databases, even write entry-level Java programs for Android. Applications must store data in tables and retrieve them as needed, depending on the needs. Structured Query Language (SQL) is the final piece of your Java application development puzzle. There are many variations of SQL, but SQLite is the one used on Android devices. Pay special attention to it as it would be a solid foundation on which you can build your career as a Java developer.

Android App Development: My Tips And Lessons Learned

Now it’s time to put everything you’ve learned into practice and build your confidence. It’s okay if you don’t feel confident enough to start coding – practice is the only way to build your programming skills and test them. Accept small tasks and write plans to solve them. Don’t let mistakes hold you back, as even the most experienced developers do. Learn from your mistakes, improve and move on to harder challenges.

As I mentioned before, an Android developer needs a set of tools to build, deploy, test, simulate and improve their applications. I recommend the following, especially if you are a beginner with no experience in starting a project:

To create applications, you need a development environment. Android Studio is the official IDE, as recommended by Google. It provides a complete set of tools that a developer would need, namely APK analyzer, visual editor, fast emulator, intelligent code editor, real-time profiler and many more. Download it and you’ll have your own Android update toolbox.

Android Studio has an easy-to-follow installation wizard. Just follow the installation instructions and you’ll be done in no time. I recommend sticking to the basic settings the first time – adjustments can follow later.

Custom Native Android Code

Note that the Java Development Kit is a prerequisite for Android Studio. Download the JDK and follow the simple installation instructions if you don’t already have it on your system. I would recommend OpenJDK, especially if you are a beginner.

All the magic happens inside Android Studio. The project has all the components you need to start your Android app idea from the ground up. Your workspace, source code, containers, test code, and other related settings all reside within the project.

After you complete the development process, all project content is packaged into an APK (Android Application Package). Make sure you choose your project name wisely because your package name (which will end up in the Google Play Store) has the format:

By now you’ve covered all the basics – you have the skills and tools needed to build your first Android app using Java. It’s time for your creativity to take center stage. The Android Studio desktop will display your directory structure, an Android phone with the words “Hello World” on its virtual screen. Let your creativity bring your app idea to life!

The website allows you to create your own study program and test your understanding by solving problems so that you never leave practice.

It provides a unique dimension to your Java programming learning experience. It’s not your typical training website. But, it is for those moments when you want to escape from monotonous lessons and want to challenge yourself. Codewars has a repository of jobs in Java (and many other programming languages) to keep you busy. You can interact with a community of experienced developers who will review your code in detail and provide comprehensive feedback to help you learn quickly.

If you are not a theoretician and you understand ideas better when they are illustrated, this is the portal made for you. GeeksforGeeks is a free resource covering all aspects of computer science. It covers the most complex collection of Java resources and effectively covers the focus of libraries, collections, lists, queues, OOP, maps and more.

Most students I meet focus more on syntax and libraries. They try to memorize it instead of focusing on Java based principles. Pluralsight lets you create patterns that help you code while staying focused on the big picture.

In this Java tutorial for beginners, you’ll take the first steps to becoming such a developer! We’ll walk you through everything you need to know to get started and help you build your first worthwhile app.

“Object-oriented” refers to the way Java code is organized:
