Android Developer Roadmap: Learn to become an Android developer

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.

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 Android developer job 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.

Android Development 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 .

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.

Kotlin

If you want something to read, the developer’s guide will keep you entertained for at least a few hours. After this — or as a supplement to the book — go check out the android developer’s guide, where you will get tons of great tips and sample code. A content provider manages how your application’s data is accessed and shared with other applications. According to the Android Docs, a content provider enables your app to share any kind of persistent data, be it stored in a file system, a SQLite database, a Jetpack Room, or on the web. An activity is an independent and reusable component that interacts with the user by providing UI-relevant resources.

Android provides several options for you to save persistent application data. The solution you choose depends on your specific needs, such as whether the data should be private to your application or accessible to other applications and how much space your data requires. Every application must have an AndroidManifest.xml file in its root directory. The manifest presents essential information about the application to the Android system, information the system must have before it can run any of the application’s code. Java is a general-purpose, statically typed, object-oriented programming language designed to be used in conjunction with the Java Virtual Machine .

Our 2022 Android Developer Roadmap teaches you everything you need to know to get started in Android development. Quality assurance is a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering products or services to customers. Dependency injectionis a technique whereby one object supplies the dependencies of another object. An injection is the passing of a dependency to a dependent object that would use it.

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.

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.

AsyncTask is basically used to reduce the load of tasks off the UI thread. It creates a background thread to perform an operation like that of fetching results from the Internet or loading data from the database, etc. and then publish the results to the main UI thread. I am passionate about sharing knowledge through open-source, blogs, and videos. To create an AVD is to use the graphical AVD Manager, which you launch from Eclipse by clicking on Window and then AVD Manager. You can also start the AVD Manager from the command line by calling the android tool with “avd” option, from the /tools/ directory.

Each component is an entry point through which the system or a user can enter your app. Android Studio is the official integrated development environment for Google’s Android operating system, built on JetBrains’ IntelliJ IDEA software and designed specifically for Android development. For the apps, most companies allocate a small budget.

• All activities have their own lifecycle, which is an important concept to manage activities and resources.
• All Android applications must be written using Kotlin, Java, and/or C/C++.
• This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
• So, when Google began building the Android system, Java was one of the most suitable languages.
• You can use them for creating the user interface together with the representation of the user interface layouts.
• Gradle and the Android plugin run independently of Android Studio.

The situation becomes challenging as in any app development you need to research, design, development, launch, and marketing within the minimum time. In the coming times, In this scenario, it is sure that expectations from mobile apps are going to increase rapidly. Some of the apps, like groceries apps, video conferencing apps, and health service apps have emerged as the need of the https://wizardsdev.com/ hour. The mobile app developers have done an incredible job by developing needful apps, especially for health care and money transactions. It has many features such as easy to add custom headers and request types, through which we can reduce boilerplate code in our apps and consume the web service easily. Network requests are used to retrieve or modify API data from a server.

The Activity class provides a core set of callback methods that tells an activity that a lifecycle state has changed. In Android, all application code runs on single thread which is main thread.All UI modifications and handling of input events will be handle by main thread. 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.

This project is inspired by Android Developer Roadmap 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.

Quickly bring your app to life with less code, powerful tools, and intuitive Kotlin APIs. Here is the list of items that you are going to need when developing Android applications. Please note that this is an exhaustive list, and you don’t need to know it all from the get-go. Get an idea of the items listed, and just start building some apps and keep the items listed in the back of your mind and have a deep dive when using them.

There are multiple ways to develop applications for Android; you can go down the path of hybrid application development where Flutter, React-Native, or NativeScript are the most common contenders. Flutter uses Dart, whereas React Native and Native Script rely on JavaScript. Answering the question of hybrid vs native is out of the scope of this roadmap.

Android provides a variety of pre-built UI components such as structured layout objects and UI controls that allow you to build the graphical user interface for your app. We hope that with this roadmap new developers will find it easier to start building beautiful Android applications.
