This article is intended for beginners to answer the most common questions about Android app development, including which programming languages can be used and how you can learn to build Android apps. Let’s get you on your way.
Getting started with Android app development
Android is a mobile operating system (OS) developed by Google that runs on smartphones and tablets built by different manufacturers, including Google, Samsung, Motorola, and HTC. Needless to say, developing apps for the Android OS can be quite challenging given the large assortment of devices they have to operate on.
What programming language is used for Android apps?
The default Android app language is Java. The Android OS itself is largely written in Java. In 2017, Kotlin was added as another official language.
Aside from Java and Kotlin, there are general-purpose languages you can use to build Android apps, including C#, Python, C++, and more. Of course, there are some app programming languages that work better for specific projects than others. With Android app development, you have options so knowing your strengths is key.

Learning how to create an app isn't as impossible as it seems if you have the right software. IDEs provide you with an interface to write, compile, and run your Android app. These tools often include additional resources and tools, like software development kits (SDKs) to make the development process a little easier.
There are a lot of factors that weigh into the cost of an app, such as its features, development method, design process, etc. Android apps typically take longer to build than iOS apps, which can make it a more expensive project. On average, most mobile apps cost between $100,000 to $300,000. Depending on the complexity of the app, you might be able to use a drag and drop app builder to get the cost down.
It’s important to keep in mind that there are also post-development costs associated with building an app, like Google Play Store fees. These marketplace fees include a $25 one-time publishing cost, plus transaction fees of 30% on all purchases for the first year. After Year 1, subscription fees drop to 15%.
How many Android developers are there?
There are 12 million mobile app developers worldwide, with almost half of them dedicated to Andriod app development. The total number of app developers is expected to rise to a staggering 14 million by 2020. So, if you’re really thinking about learning how to make apps, now is a perfect time.

Where can I learn Android app development?
While you can definitely teach yourself to code, I don’t recommend it if you’re seriously considering a career change into development. You’ll most likely end up with a piecemeal app that doesn’t stay true to core principles.
