On a worldwide basis, the Android operating system still reigns supreme. According to a report by Statista, “Android is used by about 85% of the world’s population.” There are 2.87 million applications on the Google Play Store, each one distinctive and intuitive in its own way. As a result, not only the app’s concept but a developer’s whole skill set plays a huge influence in determining whether or not an app will be a success on the Google Play Store.

So, if you’re planning to hire Android app developers and wondering what skills are required to create visually appealing Android apps, we’ve compiled a comprehensive list of some of the most important skills to look for while hiring candidates.

10 Essential Android app developer skills

Here’s the list of the most important skills you should consider before recruiting mobile app developers.

1. Proficiency in Kotlin

For designing native Android apps, developers must demonstrate that they can code in the most contemporary, popular, and Google-recommended programming language.

While Java has long been used to create Android apps, Kotlin is a newer, more contemporary language meant to be an alternative to Java. Furthermore, according to Stack Overflow and HackerRank, Kotlin was the ninth most-wanted coding language among Android app developers in 2021 and 2020, respectively, and 24.9 percent of developers picked Kotlin as the language they wanted to learn next.

These figures are unsurprising because Kotlin provides a wide range of features and tools to aid developers in the development of their mobile apps.

2. Knowledge of Android Studio

Android Studio is a graphical integrated development environment (IDE) for Android app development that provides all of the developer tools needed to create an app.

A code editor with syntax highlighting and autocomplete, a debugger for diagnosing bugs in an app’s code, log readers, app building and packaging tools, layout inspectors, unit and UI test runners, and emulators for testing code. Mobile app developers must know how to use this IDE efficiently to build production-ready applications faster.

3. Familiarity with the Android Jetpack libraries

The Android Jetpack libraries are the foundation of the Android platform; without them, you won’t be able to create an app.

There’s a lot more you can do with Android than what the basic APIs allow you to accomplish (application programming interfaces). Android developers must become familiar with Android Jetpack in order to gain access to these sophisticated features.

In summary, a developer who is well-versed in Jetpack can:

  • Create trend-driven apps that are built on contemporary design principles and have fewer crashes and memory leaks.
  • Allow users to focus on the unique value your app can bring by easily managing time-consuming but critical processes like background chores, navigation, and lifecycle management.
  • Reduce fragmentation by using supported libraries across Android versions and devices.

4. Understand how to create, package, and sign an app.

More than simply coding is required of a mobile app developer. Another skill that Android app developers must learn is packaging their apps for distribution.

As a developer, you won’t be able to upload your app to the store until you have this.

What exactly does this imply?

  • It goes without saying that developers must be able to create apps using Groovy (Gradle files) or Kotlin build scripts.
  • They must also be able to construct alternative build types (called “flavors”) with varied settings so that the app may be tested in different situations or with different behavior, whether it is being debugged or launched to the store. This allows you to put your app through its paces on a real phone in a test environment (e.g., with non-live payments or test data) without harming your production data;
  • In addition, the developer you’re considering should be able to construct quick and effective build scripts.

5. Stick to industry-standard architectural designs.

When creating a new Android app, your developers must adhere to several well-established patterns. These patterns will assist you in writing decoupled code that is easier to test, maintain, and expand.

Developers use architecture patterns to segregate concerns in the code to create clean and easy-to-use code with a modular design structure (i.e. having discrete sections). Every Android developer should be familiar with the following three prominent industry standard Android architectures:

MVVM (Model-View-Model) pattern (preferred by Android and Google);

Model-View-Controller (MVC) design pattern;

Model-View-Presenter (MVP) design pattern.

When you hire Android app developers, make sure they are acquainted with these standard architectural patterns.

6. Multi-platform capabilities

Developers must stay up with the ever-changing world of mobile app development. This ability will aid them in developing programs that can run on various platforms.

Cross-platform capabilities are essential for any app developer looking to succeed in the future, and it’s a talent that will only become more valuable. As a result, Google has released Flutter and Kotlin Multi-Platform, which allow Android developers to create apps that can run on other operating systems such as iOS.

It does imply, though, that if you have this expertise, you’ll be in a wonderful position to take advantage of the present market and go ahead of your competitors.

7. Agile development

We all know that following the Agile technique is the best way to create a high-quality product. We’ve successfully utilized this strategy to create a large number of Android apps for a variety of organizations.

For decades, agile development has been utilized in software development. It was created by the construction industry to handle large-scale projects.

Agile is a collection of concepts and ideas that enable teams to deliver software more rapidly at its most basic level. It’s an iterative approach with the objective of delivering a working product in a short amount of time.

Speed, flexibility, and adaptability will assist app developers that understand this method, which will benefit the customer as well.

8. Android testing

The ultimate goal of creating and distributing a mobile app is to increase the number of people who use it. Your team’s efforts will be useless if the app is not dependable, scalable, and user-friendly. This is why Android app testing is so important before launching it on the market.

Always keep in mind while developing an Android application that users can perform different activities, such as pushing a Submit button or downloading information to their phones. So, when you engage an Android app developer, ensure that he or she understands how to test various use cases and interactions to guarantee that the app works as expected. Expresso, Junit, Mockito, and Robolectric are the most often used testing libraries for Android apps.

9. Database

Mobile app databases are collections of structured data created to fulfill the needs of mobile apps. Database administration systems are used to maintain, update, and alter them (DBMS).

You’ll need to engage an Android app developer that can access and edit app databases using Structured Query Language (SQL). Databases are also necessary for mobile app development for various reasons, including the capacity to manage massive amounts of data and privacy restrictions.

10. Git

Even the most skilled programmers have trouble manually tracking changes to a project from time to time. Working in a group of developers just exacerbates the situation. Version control systems can assist solve this problem by offering an easy-to-use interface for app developers to make modifications to their code. Git is the most popular, feature-rich, and open-source task management software.

For Android app development, Git offers a variety of capabilities, including virtual team collaboration via branching and merging, undoing code changes that have caused bugs or performance degradation, and simplifying code reviews via pull requests.

Conclusion

Android app development may assist a business in reaching out to more customers, increasing revenues, increasing brand recognition, and establishing a loyal customer base. It can build the foundation for a company’s success, and as a result, specific mobile apps are now required in every area, from healthcare to marketing. As a result, it’s no secret that the need for mobile app developers is fast increasing, and it has become crucial to hire mobile app developers for your company. Look for the skills mentioned above while hiring the best talent for your organization.
