The 2022 Android Developer Roadmap Part1 Medium

If a security warning appears showing the message, authenticity, or validity of the software can’t be established, click OK. This also allows you to access the native functions of the operating system. Here, we would like to mention that APK is a tool that can allow the creation of your app in a virtual environment. First, you need to create your development environment to make your desktop ready to support Android development goals. The Android Studio and the Android SDK need to be installed on your computer and they are available at the following link.

Android developer roadmap

In the next window, a list of the tools will appear that can be downloaded. Kotlin is a good compiler that is specially designed to develop Android Apps. Android Studio is an IDE , an interface where your code can be entered . During this process, ensure the usability, compatibility, security, and performance of the app.


If you’d like to get notified as we release future posts, join the watchers on GitHub or follow Stream on Twitter. You only need to look at the sections that seem helpful to you. Also, please note that this roadmap is opinionated, so if you have different opinions than those of the author, we’d love to hear them. Moshi is a modern JSON library for Android, Java and Kotlin.

Android developer roadmap

Kotlin is a cross-platform programming language that can be used as an alternative to Java for Android App Development. It has also been declared “official” language by google . The only sizable difference is that Kotlin removes one of the features of Java such as null pointer exceptions. It also removes the use of semicolon at the end of every line .

Don’t forget to test your code

Here is the full version of the roadmap in a single image and after that we have the broken down version with the resources and links to learn more about each of the boxes. Somewhere along the way, you should check out this wonderful tutorial on creating a “real-life” application. Again, don’t be intimidated by the amount of information on this roadmap.

  • This project includes a demo project which shows the roadmap image.
  • So when we perform some slow and long running task which block the main thread for a while or may be forever, so to avoid that situation we have to perform long running asynchronously by using Thread.
  • Now that we know what are some of the cool features provided by IDEs, let’s look at some of the most popular IDEs used for Android development.
  • The videos should be your best source of information really…
  • Community created roadmaps, guides and articles to help developers grow in their career.

If you are a new Android developer, buckle your belt. With the evolution of rapidly changing android technologies, it is a big decision for an android developer to choose the platform, language, version, and so many other things. Taking a wise step and moving ahead by mastering the latest developments and learning android development will help you set miles ahead of all your competitors. This content is a suggested learning path to help guide your Android studies. To use this content, have in mind that the roadmap has macro boxes, that are in the middle , and from them we have micro boxes, that are more refined content about the topic of the parent box. Model – View – ViewModel is the industry-recognized software architecture pattern that overcomes all drawbacks of MVP and MVC design patterns.

Use Cases of Intents

Also, please note that this roadmap is opinionated, so if you have different opinions than those of the author, we’d love to hear them. Version Control Systems record your changes to the codebase and allow you to recall specific versions later. There are multiple Version Control Systems available, but Git is the most common one these days.

Android developer roadmap

You will continuously learn and explore new possibilities with different programming concepts and programming paradigms such as reactive programming. Of course, that was just the basic explanation of main topics like activities, fragments, or popular Android Jetpack libraries. Testing is a fundamental part of the software development life cycle .

It makes it easy to parse JSON into Java and Kotlin classes. So we’ll cover some of the most popular libraries that will make your network handling on Android easy. Data Access Object – contains the SQL statements required to insert, retrieve and delete data within the SQLite database. The problem is that dependencies can be hard to mock. Dependency injection can be a huge help in making unit testing work for you. One of the best ways of ensuring that your program doesn’t blow up is testing it with unit tests.

Entities – typically a data class that defines the schema for a table within the database and defines the table name, column names, and data types, and identifies which column is to be the primary key. It defines a standard way to do DI in your application by providing containers for every Android class in your project. In software engineering dependency injection is a technique in which one object supplies the dependencies of another object. Very few Android apps today consist of just a single screen.

By isolating user resources from one another, they can be protected from each other. Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android.

This project is inspired by Android developer job 2020. So thank you for the authors providing the roadmap ideas. Also, you can learn a lot of knowledge from the repository. This project doesn’t cover everything, so if something is missing or should be fixed, anyone can contribute to this project by following the CONTRIBUTING guides. 🗺 The 2022 Android Developer Roadmap suggests learning paths to understanding Android development.

All Android applications must have at least one activity to enter the app and interact with users. The Model–view–presenter is a derivation of the model–view–controller architectural pattern which mostly used for building user interfaces. InMVP, the presenter assumes the functionality of the “middle-man”. InMVP, all presentation logic is pushed to the presenter. App components are the essential building blocks of an Android app.

A skilled Android developer can fix the problems of millions of people. This project includes a demo project which shows the roadmap image. In addition, you don’t need to learn everything from this roadmap. So we recommend only reading the sections that would be helpful to you. There was a problem preparing your codespace, please try again. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

A key goal of software engineering is to produce code that is clean and easy to maintain. The code is clean when it is simple, readable, and understandable. This is not the case with code where dependency injection isn’t used. Android Studio is the official IDE for Android development built on JetBrains IntelliJ IDEA software. It’s a software suite that was built by Google and has all the Android development tools built-in for a high-quality Android app.

Every Android project must have an AndroidManifest.xml file which describes essential information about the application such as the package name, entry points, components, permissions, and metadata. I would highly recommend watching this free course from Google on Developing Android Apps with Kotlin. Also, here are some of the resources to learn more about the topics listed above. Broadcast receiver is a registerable listener that listens to broadcast messages from the Android system and other Android applications.

This situation has improved considerably, with the introduction of the Navigation component. Not to worry though, Android provides a lot of pre-built components which help in creating apps. Kotlin has taken over from Java as an official android development language. Developed by JetBrains in 2011 and it has been in constant development since then. Android Developer Roadmap 2022 suggests learning paths to understanding Android development. You can read the roadmap following the line path in the middle of the map.
