How to Create Your First Android App in 2021

Learning how to make an Android app isn’t easy.

If you want to build one from scratch you have to develop an understanding of code, which can make the app development process time-consuming.

The good news is there are plenty of resources available online that can help. These materials make it possible to learn how to create an Android app on your own.

If you’re dedicated, you can gain the essential skills in just a few months.

In this article, we guide you through the app creation process. We’ve included links to the most helpful resources available for learning to code and learning Android development.

Do You Need to Learn to Code?

First, you need to learn to code if you want to create an app from scratch. If you don’t want to learn to code, you can use an app builder to create one based on a template.

In the first section of this article, we’ll focus on how you can learn the basics required to code your first app.

At the end, we’ll show you how you can create an Android app using AppInstitute’s drag and drop platform.

With our app builder, you can create an app in just a few hours. It’s the perfect choice for people who don’t have the time to learn a programming language needed to code.

Getting Started with Your Next Android App

There are two steps to learning how to create an Android app from scratch.

  1. You need to learn the language used to code mobile apps.
  2. Then you need to learn how to use this information to build an app.

Android apps are built using Java or Kotlin. While Kotlin is the official Android studio language, we’re going to focus on learning Java as it is more widely used.

We go into further detail about why we made this choice later in the article.

What Is Java?

Java is a general-purpose programming language used to create software on a variety of platforms.

It’s one of the most popular programming languages, so by learning it you’ll gain valuable app development skill.

You can use Java to build:

  • Android apps for the Google Play Store
  • Web applications
  • Windows desktop apps
  • Linux desktop apps
  • Mac desktop apps

There are plenty of online courses that teach you the basics of Java.

We like those provided by Coursera and Treehouse as they both start with a basic Java course before teaching you more about building an Android app.

This adds structure to the learning process and keeps pushing you towards your goal of building a mobile app.

  • Treehouse’s Beginning Android program starts with a Java Basics course that teaches you how to code in Java. It then goes on to teach the basics of Android app development. By the end of the course, you’ll know how to create simple mobile apps.
  • Coursera has a highly rated Android App Development Specialization Course provided by Vanderbilt University. It’s designed for people with no prior knowledge and goes through the various stages of learning how to create an Android app—starting with learning Java.

The downside is that you have to pay for both these courses. However, there are some free resources you can use to learn Java. Here are a few of them:

  • Udemy has a free Java tutorial course with over 16 hours of video. It has a 4.3 star rating, and over 1 million people have signed up to the course to learn how to code.
  • CodeAcademy has a beginner’s introduction to Java which you can try for free.
  • Stanford University’s Programming Methodology Course teaches Java, although it looks a little dated.

What about Kotlin?

In 2017, Google changed the official language for building Android apps to Kotlin. This is a new programming language that is described as a more streamlined version of Java.

This raises the question of whether someone who wants to create an Android app should forget about learning Java and study Kotlin instead.

Most current advice suggests that if you are a complete beginner you should stick to Java because it is a more established language.

This means there are a lot more resources and help available. For example, the learning courses we have linked to above start with a section on learning Java, not Kotlin.

If you want more information about why learning Java is the best choice for most new Android developers, check out this Medium post by Javin Paul.

In the article, he also explains why learning Kotlin can be advantageous if you are already a proficient programmer.

Learning Android Development

Once you know the basics of Java you can move on to learning how to use this knowledge to create an Android app.

The Treehouse and Coursera courses listed above both teach the basics of Android app development following their sections on Java.

However, they aren’t the only available resources.

  • Google has produced a guide that shows you how to build a simple mobile app that displays “Hello World” using Android Studio. It also teaches you how to test your mobile app and build a user interface. It’s pretty basic stuff but crucial to know if you are new to app development.
  • Udacity has a free course that is recommended by Google called Developing Android Apps. It combines theory and practical tips to help you create your first Android app.

The Essential Android Development Tool: Android Studio

Android Studio

When building Android apps, you’ll need to download Android Studio. This is the official Integrated Development Environment (IDE) for Android, and it was developed specifically for creating apps on the mobile OS.

The development environment has a ton of features that simplify creating Android apps. It has an easy-to-read user interface with a code editor, a preview section that reflects your changes as you make them, and plenty of templates and sample apps. It also integrates with GitHub.

You can download Android Studio for free from the Android developer’s website.

Google has also created a vast resource for learning how to use Android Studio; you can check it out here.

This contains best practices and a list of core topics that cover everything you need to build an app.

While Android Studio is the primary IDE for Android apps, in the past there have been alternatives.

Eclipse was the primary IDE for a while and many tutorials that haven’t been updated mention this program.

However, it is no longer supported and Android developers should use Android Studio instead.

Resilience Is the Key to Creating Apps

As you may have realized from the information in this article, creating an Android app is not easy if you don’t already know how to do so.

Understanding Java will be a big help, but even then you’ll still have a lot to get to grips with. If you have never coded before, your journey to create an app will be even longer.

Depending on how long you can dedicate to study, you can learn the basics of Android app creation in a few weeks and create your own app within a few months.

Even if you have a full-time job or other commitments, by sticking at it you can learn all you need to know to get started with the app creation process in a relatively short period of time.

The key is that you need to keep going. Coursera estimates that you can complete its Android App Development Specialization course in around five months by putting in just four hours per week. This is a manageable amount of time for many people.
