What Is an Android App Developer? Your 2025 Career Guide

Whether for fun, work, or productivity, we depend upon our phones to help us with our daily activities. We use applications on our smartphones for everything from ordering dinner, creating documents, and even watching movies—and more apps get developed every day.

As an Android app developer, you can create apps used on Android devices. Apps have turned mobile devices into handheld computers and transformed the way people interact. As an Android app developer, you could be part of this mobile revolution by creating apps that are relied upon by smartphone users everywhere. 

An Android app developer is an entry-level position, but certain skills are required to obtain this kind of job. For starters, you’ll need an understanding of programming languages to create the code behind an app. We’ll explore these, along with other skills needed to pursue this career.

Android programming languages

One of the most notable skills of an Android app developer is their knowledge of different programming languages used to develop apps. Here’s a look at some of the programming languages that mobile app developers use:

Java

For a long time, Java was the official programming language of Android apps. While the preferred language has changed to Kotlin, Java is still a popular language choice of many developers. However, the language is complex and has a high learning curve for beginners.

Due to the popularity of this language, there’s a good support community to help developers troubleshoot problems, and Google’s Play Store widely supports it.

Kotlin

Google declared Kotlin the preferred language of Android apps in 2019. Kotlin is an easier language to learn than Java, as it doesn’t have as much complexity or as many nuances, making it easier for developers to pick up.

Dart

Dart is an up-and-coming language created by Google. The purpose of Dart is to create apps in less time with more built-in features and easy-to-design graphics. This language tends to focus on the user experience too. With the end-user considered during the development, apps tend to be more user-friendly.

C++

C++ is still used, but not as an app’s main programming language. Some developers like to use it to build certain pieces of an app, but combining it with other languages can create bugs. While budding developers should be aware of this language, other languages will likely take priority.

A day in the life of an Android app developer 

As an Android developer, you’ll likely spend time collaborating with colleagues, writing code, troubleshooting tech problems, and working to improve applications. More specifically, daily duties might include: 

- Working with different departments to understand an app’s purpose

- Strategically designing an app’s navigation with a focus on the end-user

- Managing outside data sources and APIs to facilitate app development

- Writing code to make the app function simply, but with purpose

- Testing the app and fixing bugs as they arise

- Reviewing an app with various team members

- Staying on top of trends in the industry

What skills are needed to become an Android app developer?

If becoming an Android app developer sounds like a good career fit for you, here’s a look at the skills you should work to acquire:

Programming languages

It’s advantageous to be proficient in two programming languages, like Java and Kotlin, as you’ll use these languages to write code that makes an app function. You’ll likely need to take classes to obtain this technical skill. 

Additional software knowledge

It’s a good idea to be familiar with the Android Development Kit, which is Google’s app developer toolkit. Also, knowing SDL, a program designed to manage and store data is helpful. Developers should also review the Material Design Guidelines set by Google. These guidelines must be met for an app to appear in the Google Play Store. 

Strong communication skills

Developing an app is a team effort. Depending upon where you work, you might work with other colleagues or clients to build an app. The ability to listen and respond to a person’s needs might seem simple, but it’s a vital part of building an app efficiently. 

Attention to detail

As a developer, you’ll write hundreds of lines of code. It’s a skill that requires attention to detail. If a character or letter is off, the code won’t work. Attention to detail will ensure your code is well-written and ready to test. 

Ability to adapt

The world of mobile apps is constantly changing. New programming languages can emerge, standards might change, and software will evolve. An app developer must be able to adapt.
