That being said, for many new developers, Android apps are considered more manageable, faster and cheaper to develop than iOS. This can be credited to the fact that Android maintains more flexibility and structure for controlling code, intents, fragments, and services, as can be further explored here. So, as a new developer starts on this journey, a key question is ‘how to create an app for Android’, specifically which apps are great to start as a foundational base.

Essential Steps for Beginner App Development

Before we list several recommended mobile app examples, let’s first summarise five steps for beginners to follow when starting app development.

  1. Ideation Stage: Before commencing app development, you require a viable idea of what you aim to create. As a beginner, it’s important to be teachable and start with the basics. So, the principal focus should be creating an app that is simple, fun and can incrementally build your skills. For example, building layouts, exploiting databases and generating lists and arrays. 
  2. Set Up and Installations: During this stage, new developers should install and set up their development environment (IDE) appropriately. This process entails installing development software tools like Android Studio, creating Android Virtual Devices (AVDs), and connecting hardware devices on which to install your applications.

Generally speaking, Android mobile apps are based in principle on the Java programming language. This means you have to have some competence in Java basics as you start off. This also necessitates you to download the Java development environment.

  1. Development: For this step, you should appropriately set up and develop your Android project, which will contain all of the source code and resource files for your mobile application.
  2. Debugging and Testing: During this stage, a beginner builds their project into a debuggable.apk package(s) that can be installed and run on the emulator or an Android-powered device.
  3. Publishing: in this phase, the beginner will configure and build their application for release and distribute their application to users.

Taking Baby Steps with “Hello World”

In all honesty, you can fly before you walk. And this means that it’s essential to start with the basic “Hello World” demo app to familiarise yourself with displaying text after consuming a few tutorials. Furthermore, starting with this helps to build your confidence as you dip your leg into the water before falling into the deep end.

Calculator Application 

The next app for beginners trying to get acquainted with creating an app for Android is a calculator app. This app can be built with basic knowledge of Java and can help develop your logical programming abilities. Furthermore, calculator apps don’t constitute a database yet, which is great as you start off.

Furthermore, a Calculator app will provide you with an excellent foundation to understand how important “user experience” is while creating an app. it should take you approximately 20 minutes to code and compile a basic calculator (capable of addition, subtraction, multiplication or division). Afterwards, try your hand at more advanced calculations such as trigonometric and exponential calculations.

A calculator app can also teach you how to handle multiple functions, the structure of an application, application layouts, and position elements. Once you have achieved the calculator app, you can proceed to practice with apps that involve arguments, different types of loops, arrays, conditions to save you from overly lengthy code.

Later on, assuming that you are sufficiently knowledgeable with the Java basics, you can take on projects that require database development. You should be aware of the type of database you wish to use in your mobile application. After setting it up, you will probably have to normalise the database, which will create several tables that later can be connected via a primary key. However, implementation approaches for databases may vary across different database types. However, the logic behind databases remains constant.  

A Unit Converter App

The next app you can attempt to build is a simple unit converter. This app can be designed to convert miles to kilometres, then convert kilometres to miles. Progressively, you can introduce more conversion metrics, for instance, kgs to lbs, inches to centimetres, Degree Celsius to Degree Fahrenheit etc.

A unit converter app can help you to understand how to: take user input and display output, perform simple math operations, design switching options.

Stopwatch App

You can also trial a simple stopwatch app with two buttons. One can be a dynamic button, and the other a fixed button. You can design the first as the Start button, and once a user clicks on the start button, the name on the button can change to Stop, and then change to Start again if clicked. Finally, the other button can be the reset button. Pretty simple, right?

The benefits of attempting such an app are that it will teach you how to utilise the date-time object, calculate the time difference, and create a dynamic button, which are all valuable skills as you learn how to create apps for Android.

Music Player App

You can also attempt to build a music player app (it doesn’t have to be a Spotify clone though). But a fully functional music player that works in the background while using other apps. Developing such an app can build your competence while creating apps that work in the phone’s background, use multithreading, and employ audio files.

Budgeting / Tracker Apps

Another simple application you can build is a tracker app. This app can track calories or even budgets. Such a financial or nutritional tracking app can teach you how to take inputs and process them to make calculations. Understanding such underlying concepts can later prove helpful to help you build a mobile app with any functionality you want with the ability to display the statistics.

For example, an Expense Tracker app that tracks the monthly expenses and visualises data appropriately across various charts and graphs can teach you how to work with graph and chat visualisation tools that are commonly used in apps nowadays. Building such an app can also train you to work with overall database interactivity based on dates and times.

Quiz App

Another app you can try building is a quiz app. Such an app can build your ability to: work with list views, deploy items in the listview dynamically, dynamically insert elements (such as buttons or text views), switch between activities using Intents or Bundles, practice RecyclerViews and ArrayLists, handle Splash Screens in UI design.

More Advanced Steps to Take

Assuming that you’ve attempted some of the aforementioned apps, you can now try to get acquainted with API calling and lazy image loading. Try creating some Wallpaper apps with open-source APIs which avail a collection of various images. Afterwards, you can practice default control management over components like contact list, message sending and receiving, and the android settings page, etc.

Once you have these skills in the bag, you can now proceed to construct advanced chat, audio calling and video calling applications.

Honourable Mentions (More Advanced Apps to Try)

  • You can build an earthquake app that fetches data from a web API and loads different earthquake occurrences globally in RecyclerView. This can build your skills in making API requests, parsing JSON, and working with AsyncTasks and Loaders.
  •  A simple To-Do list App that tracks your daily activities and notifies you of appointments can also suffice. This can help you build experience while handling databases and notifications.
  • Apps that leverage various sensors of Android devices like Accelerometers or Gyro-sensors.
