Android App Development

The Android system runs the majority of devices around the globe. So launching an Android app enables access to the lion’s share of potential users. Android applications are providing a vast number of features, such as widgets or QR code readers. Developing an application is quite a simple procedure, but it can include pitfalls in several stages. In this article, we will distinguish the main steps in the android app development process. Let’s get started and develop a flawless application on the Android platform.


A guide for developing Android applications for beginners

We will start by defining the key stages involved in Android app development. Even if you don’t have any experience developing an Android app, follow these steps to make the process as effective as possible.


Step 1: Develop an idea or concept

The first and principal step in Android mobile apps development is generating an idea. You can come up with something completely new or upgrade the features of an existing application. If you don’t want to create an idea from scratch, there are other options. Find a problem that needs immediate solving and provide a solution inside your mobile application. Another variant is to combine the features of existing popular applications. Think about how your new app can attract the user’s attention and surpass the existing leaders.


Step 2: Set the app strategy

Even if your idea is flawless, it is necessary to realize how to implement it and make your app popular. Start by analyzing competitors —define their weak points and strong points. Monitor their download numbers and user reviews. The best solution is to find a development partner or an outsourcing company to conduct the research and deliver the optimal strategy. It is necessary to take into consideration the latest trends in Android development in 2021. This step is crucial for selecting monetization methods to make your business profitable.

Step 3: Application framework

Download the required tools, such as Android Studio (the standard Integrated Development Environment (IDE)) and Android SDK (a software development kit that you don’t need to be a professional to use). Android Studio is a place to input your code and access all the tools, such as libraries and APIs, to enter the UI. It is powerful software, which will detect the wrong value if entered. There are several tools, which are helpful at this stage. For instance, Gradle helps debug your app code and Fabric, a framework that provides ready-to-run development kits to choose from. Or you may create a custom one. To start a new project in Android Studio:

  • download the Android SDK;
  • select a programming language based on requirements (JAVA, Kotlin, Go, C, C++);
  • choose the name of your application;
  • select the main page from the “activity module” and other things like Functionality or Layout;
  • introduce the folders and the layout file

Pay the most attention to functionality, unique app design, and convenient User Interface (UI). Don’t forget to consider the market’s tendencies if you want to keep up with the user requirements.

This step needs more technical preparation. You should learn the basics of Android mobile application development before starting the process yourself. But the tools provided by Google are the optimal opportunity for software development, as they include all the required application details.


Step 4: Set the Minimum SDK

Minimum SDK means the lowest Android version, which your app will be compatible with. The lower this number, the more potential users your application gets. The latest versions have a relatively low adoption rate, but remember that some brand-new features are available only for the latest versions. So, if you want to count on them, choose the lowest possible version or develop another digital application strategy. 


Step 5: Test your application

Although most of the Android development process is automatized, it is necessary to implement thorough app testing. You should be confident that your application contains no bugs or errors. Android Studio provides excellent services for that, such as Virtual Device Manager, which has a drop-down menu on the left side with a phone model name. You need to set up an Android emulator beforehand to be prepared. If you click on the green arrow on the top of the controls, you can begin your application testing right away. It enables using an emulated phone as if it were a real device. Moreover, you can try different virtual device settings, such as screen size, Android version, etc. Before you get to testing, make sure your virtual device corresponds to your lowest SDK. 

Another variant is to connect a real mobile phone for testing. You have to activate the Developer Options and allow debugging via USB. Don’t skip this stage. It is better to detect a bug at an earlier stage than to lose the users’ confidence.


Step 6: Launch the app

Having reviewed and tested your app, you can go to the Google Play Store to launch it. Google implements a set of specific standards for publishing data. It is better to get acquainted with them beforehand. If an application passes this stage, it is available to download on the PlayStore.


Step 7: Post Publication

Developing and launching the Android app is not the whole procedure. The next step after publication is to gather as many user reviews as possible. Remember that you should never stop improving if you want to remain competitive in the market. Fixing possible errors and upgrading is necessary for any application. Monitor the competitor apps and include fresh features that will make your app even better, and your enterprise even more successful!

Android App Development

The Bottom Line

To wrap it up, the methodology of Android development is relatively straightforward, and the process can be performed quite quickly. Of course, it depends on the application complexity and the number of features it provides. The core point is to develop a useful idea and effective strategy. The development stage doesn’t require as many skills as you may think. Moreover, there are many helpful tools, so writing an app code from scratch is not always necessary. Testing can be implemented inside the Android App Studio, and developers may even customize the emulator features to test the app on as many models as desired. Never stop making your app better after the launch, and it will gain huge success. We wish you good luck with your Android Development.
