With more than 6.4 billion smartphone users globally, it is no wonder that the mobile application industry is flourishing. The mobile app tradition and smartphone infiltration are still mounting at a firm rate, without any signs of decelerating down in the predictable future.
According to research, more than 218 billion different mobile applications were downloaded in 2020, and 88% of the mobile time will be spent on different applications. By the end of 2023, mobile applications are expected to produce more than $935.2 billion in revenue.
The mobile application development industry is growing at a rapid pace. To flourish in this digital evolution age, you must get familiar with the fluctuating mobile application development drifts.
With the average smartphone owner using ten different mobile apps daily, your business needs to build a mobile app to entice users' consideration. In that case, you need to focus on picking the accurate expertise and mobile app development language to develop a powerful, creative, and user-friendly app.
The prospects and success of digital media depend significantly on Android phones. It essentially alters commercial models, functional mockups, and markets astonishingly. However, another terrifying fact is that 80% of mobile apps fail after the first time.
The key reason for this catastrophe is the failure to monitor and execute the latest mobile app expertise and drifts. Unfortunately, this inadequacy also marks trailing behind a more technically and scientifically flexible competitor. Therefore, the initial step to making your mobile application successful is to stay modernized and effective with the latest mobile application progress trends.
What is Android?
Android is an operating system built on an improved variant of the Linux kernel used to build several mobile applications. It was launched by Google in September 2008 and was developed by an association of developers known as the Open Handset Alliance.
Did you know that the number of active Android users increased by more than 2.5 billion, spanning over 190 countries? In addition, Android has been rated as the most preferred operating system among users with the smartphone. Driving several brands of phones and tablets, Android has stretched to all bends of the globe.
What Are Android Applications?
An Android application is an operating system built on the Android platform. Because the Android manifesto is developed for small devices, a straightforward Android application is built for a smartphone or a tablet to function on the Android operating system (OS).

How do I Build Android Applications?
To build an Android application, you need to perform a few steps from the Android application builder:
- Choose the type of software
- Select a similar application to your idea
- Choose the features you want:
- Pick the launch platform:
- Select your team and delivery time
- Launch the application
Step By Step Guide to Develop Android Application
Step 01 - Download the Tools of Your Choice
The first step you need to perform is to produce a development environment to organize your desktop or laptop to provide your Android development goals. You will need Android Studio and the Android SDK, and both of these will come bundled and organized in a single file that can be downloaded from the official android development website.
Android Studio is an Integrated Development Environment (IDE) fundamentally a platform where you can insert your code, which is mostly Java or Kotlin. You can retrieve all the various tools required for development from Android IDE.
Android Studio allows you to retrieve collections and Application Programming Interface (API) from the Android software development kit, thereby providing you entree to automatic functions of the operating system. You will also develop your Android application into an Android application package using Gradle.
And this is not it. There are several other choices accessible for building Android applications. Unity is a robust instrument for building games on the fractious platform that also provisions Android. Likewise, Visual Studio with Xamarin is an outstanding compound for creating cross-platform applications in several programming languages.
Step 02 - Create a New Project
After you are done downloading the Android Studio on your desktop or laptop, the second step is to create a new project. This is an easy process, but you will be required to make several choices to influence your Android application. To create a new project, click on File. Then, from the available options, select New and click on New Project and select a project template.
The project template states the code and user interface essentials that will be comprised in your new application when it loads. For example, while selecting a project template, the word Activity will refer to a screen in your application. Therefore, a project with No Activity will be entirely blank, apart from the elementary file structure.
Basic Activity refers to creating a preliminary canopy for your application and will enhance an icon at the lower right and a hamburger icon and menu at the top. These are mutual fundamentals in all Android applications, so this can help you save time.
Java vs. Kotlin: Which is Better?
As an Android application developer, you need to decide which programming language you will learn, Kotlin or Java. Google and Android Studio formally support both programming languages, but they have some discrete modifications.
Kotlin Programming Language
Kotlin is an open-source, inanimately captured programming language that JetBrains developed. Kotlin offers a brief code composition that makes it one of the most dominant picks for Android mobile application developers. Some of the significant features of Kotlin are:
- Kotlin is efficient in that it codes your mobile app easily as the syntax is intuitive and lean.
- Kotlin allows you to enhance additional features to your prevailing application, making it simple for you to complement modest yet inspiring features.
- Kotlin certifies that each variable works as a non-null, tumbling the number of crashes at runtime.
Java Programming Language
Java is the most common multipurpose object-oriented programming language (OOP language) used for developing android applications. In addition, it is a platform-autonomous universal language used for programming. Therefore, it has been a prevalent choice of language in several enterprises for decades. Some of the significant features of Java are:
- Java is a multi-pattern, feature-rich, inferred, and dominant programming language that provides great efficiency for developers.
- Due to its regressive compatibility, Java is a substantial enterprise application necessity.
- Consistent updates make Java the number one choice of developers.
- The runtime of Java Virtual Machine (JVM) is the best amongst Virtual Machines in the Information Technology business.
Minimum Software Development Kit (SDK)
The last thing you need to reflect on is the Minimum software development kit (SDK). SDK is the lowest variant of Android that is important for your application to support. The lesser you make this number, and the bigger your potential audience will be.
Step 03 - Acquaint Yourself with the Files & Codes
When creating an Android application, there are multiple files, folders, and codes. However, this may not be the case if you use Python to develop the application.
Introducing Layout Files
A layout file code is somewhat discrete from a Kotlin or Java folder. This describes how an action appears and permits you to add other stuff like buttons, text, and browser windows.
You can find the layout files from the drop-down menu of My Application. Now, From the drop-down menu, select app. Now expand the menu for SRC and click on RES. Then, from the available options, click on layout.
In the design view of the layout file, you can drag and drop multiple widgets onto the screen. The code view demonstrates a freight of XML scripts. The script will update when you add new widgets through the design view.
Similarly, you can twist other properties of the widgets and see them replicated instantaneously through the code view. In the massive popular apps, you will need to develop a new Java or Kotlin file (depending on the programming language you are coding in) and an equivalent extensible markup language (XML) file every time you want a new action.
The Android Manifest
The Android Manifest is an extensible markup language (XML) file in the "res" folder that describes significant features of your application. That comprises the application's alignment, the actions that you are required to be involved in it, the type, etc.
The drawable folder is located in "res," where you will insert images that you want to position later.
A value source folder is valuable to stock principles used universally across your application. For instance, this can embrace color codes (making it simple for you to redefine the look and feel of your complete application), threads, or thesaurus. You will outline these principles in separate XML files, such as fonts.xml.
Gradle is the tool that receipts all your files and packs them into a practical Android Application Package (APK) for testing. It is also beneficial for producing broadcasts and previews etc. In case if you are looking to add a "dependency," Gradle will help you with it. Dependencies are peripheral collections that permit you to retrieve extra functionality within your code.
Step 04 - Test Your Application
When acquiring a new skill or learning a new programming language, the first thing you need to do is develop an application that says "Hello World." Gratefully, it is really easy with the programming languages offering the easy codes to develop this. For example, if you look at the extensible markup language (XML), it comprises a simple tag that states "Hello World!"
If you look at the panels at the top, you will see a little green play icon. On the left-hand side of the icon will be a floating menu with a receiver term in it. When you downloaded the Android Studio, you must also have downloaded an Android system image along with the Virtual Device Manager.
By clicking on the green icon, you will unveil the application you developed and test it. Please make sure that this will also allow you to utilize the emulated phone as though it were an actual device.
By the way, you can alter the settings for your virtual device like screen size, screen resolution, aspect ratio, Android version, etc. This can be done by navigating to Tools and selecting the AVD Manager.
Step 05 - Make it Happen
The best way to acquire Android application development is by doing! This means you should attempt to make amendments to the code to check if you can add something different to it. For example, altering the text that is displayed is as easy as opening your extensible markup language (XML) file and changing the text that states "Hello World!" into "Howdy & Welcome!"
Now you need to add the altered code to your Main Activity. If a text appears red or is marked as red while typing, you need to import the code from the Android Software Development Kit (SDK). Then, click on the word that appears red and press Alt + Enter. The Android Studio will update the code mechanically.
There are approximately 8.1 million applications on Google Play Store and Apple Store collectively. So, what can make your newly developed app stand out? Well, the new trends can make your app stand out.
If you follow the steps mentioned above properly, and if your application works without bugs or leverage the users with a robust feature-rich app, your app will get the attention it deserves and be genuinely rated as the best Android application example.
The mobile app market will grow quickly, and mobile application development will progress. However, relentless learning and persistent responsiveness are the only ways to endure the cut-throat competition.
