What is Android App Development?

The android app development process is any programme produced to be supported by the Android OS utilising the android software development kit (SDK) on android studio.

Google designed an open-source operating system for mobiles. The Android operating system is developed using Kernel. 

Because of its open-source nature, most Android developers have adopted a variety of graphical user interfaces, even though they all share the same underlying operating systems. 

The open-source code used to generate Android applications is known as the Android Open Source Project (AOSP).

Android is an open-source OS with the most fantastic developer community, so it has more marketing and inter-app interactions.

Android developers draw toward this field because of the lower prices and resources and the highest success rates built in the wealthiest development environments.

Android is the largest market in today’s technology world due to its beautiful user interface, the most excellent connectivity rates, storage, media support, and messaging. 

Web browsing, multi-touch, multitasking, resizable widgets, android beam, Google cloud messaging (GCM), and multi-language are additional capabilities.

Since 2011, Android has been the most popular operating system, with over 2 million monthly active users. Android comes in various versions, each with its own set of features that set it apart from the rest. 

Android 11 is the most recent Android version to hit the market!

Now let me tell you about the architecture for building applications in Android Systems.

Android Development Architecture

The Android architecture starts with the primary user interface, which is responsible for the front end of android apps such as calculators, clocks, emails, and wall clocks, among other things.

The android framework, which includes the windows firewall, service providers, and various managers such as packages and activity managers, is the second layer of the android architecture.

Library and the Android runtime make up the third layer, which contains Mysql, HTTP, SQL, Lib-c, and many more.

The Kernel is the lowest layer of the operating system, and it includes all of the drivers, including Wi-Fi and Wireless drivers.

As you got a slight hang on the architecture of Android, let me provide you with the basic libraries that are required.

Android Development Basic Libraries

The libraries are the foundational tools for creating Android applications. The following are some of the libraries used in Android development and their primary features.

  1. Android.app: This library is the foundation for all Android applications, as it is the key to accessing the application’s model.
  1. Android. Content: This is the second most essential library, and it supports content access and the relationship between application components and the messages they exchange.
  1. Android’s core database is SQLite, and this library is used to connect the programme to it and retrieve its data using content providers.
  1. Android.OpenGL is a package that enables visual 3D rendering via the JAVA interface utilising the Java Development Kit (JDK).
  1. This library provides android applications with operating system functions such as messaging, inter-process communication, task allocation, and memory management.
  1. Android. Text is a package that provides text manipulation and allows applications to create text visuals on Android devices.
  1. Android. View: This is a crucial aspect of programme development that allows for changes to the user interface.
  1. Android. Widget: The library’s introduction provides user interface components like lists, buttons, scroll bars, layout managers, and radio buttons.
  1. Android.WebKit: This is the library used to inherit web applications and add web browsing functionality to them.

Now let us discuss the framework of android development.

What is the Android Application Framework? 

Android applications are produced in the Android Studio IDE, which allows any resolution to be configured for any Android version. 

The Application framework: Java provides high-level front-end services in the form of classes. 

The following are the essential functions of the Android application framework:

Activity Manager: The Activity Manager is a Java class included in the Android application that interacts with all of the activities that currently have the application interface and operate on the programme overhead.

Content Providers: The content provider class serves as a data provider for the application’s other courses. It acts as an intermediate for requests governed by the ContentResolver category.

Resource Managers: This tool window allows you to manage all of the resources associated with the application you’re working on. 

The resource provider may be used to import giant drawables into the project.

 The resource manager maintains a sort of resource is the application logo, which is named mipmap in the application settings.

Notification Managers: The notification is displayed in the title bar of the Android app, and the notification manager can easily change it. 

The notification class, which leverages the notification management class from the context, can be used to create notifications.

View system (Layouts): This is how the user interacts with the screen and sees the shown functions. Widgets are objects that include things like buttons, TectView, and ImageView.

Now let me give you the skill sets required to become an Android Developer.

Top 5 Skills Required for Android App Developer

To become a successful android developer, you must have these five essential skills and work smarter to develop excellent additional skills to work in a diverse arena for android app development projects.

Android App Development

Let me give you detailed input on the required skills to become a perfect android developer.

#1 Programming Language

Any android developer building a mobile application requires knowledge of designing and programming. A Well-versed person with skills can break down the technology step-by-step. 

As phones have smaller screens and more straightforward processes, android developers should know programming technologies.

Programming Technologies

Java and Kotlin are two major android development languages that you can use to develop applications on Android. 

You need to understand better these programming languages that include syntaxes, frameworks and generic.

Developers must learn the polished and precise code to bring high performance. But to have the version, you have to be well-versed in tools.

Programming Tools

An IDE, or Integrated Development Environment, is essential in large-scale coding and project management.

The IDE provides all of the necessary tools, services, and code templates so that developers can get right to work. 

The IntelliJ IDE serves as the foundation for Android Studio and supports a wide range of Android SDKs. 

Android Studio provides several features that make it easier for Android developers, such as code completion, auto-suggestion, code debugging, memory and CPU monitors, etc. 

Mastery of Android Studio is required for successful integration. Android SDK is pre-packaged Java code that enables easy access to mobile device-specific hardware and functionality, such as the camera and accelerometer, to offer end-users a native device experience. 

Gradle is an Android SDK library that connects external/third-party SDKs to create a seamless application experience.

External services can use the Application Programming Interface (API) to access the services and exchange data with them. 

As a result, an android developer must be able to work with a variety of APIs that are employed in the most recent app features. 

Furthermore, because running applications require SQL databases, a database is essential for the android development process. 

As a result, android developers need to be well-versed in database management tools and databases.

#2 Designing Skills

For end-users, Android apps have a front-end interface. The user interface includes visuals, patterns, controls, and animation (U).

Typically, designers are hired for large projects. However, some projects require developers with essential android UI design skills and experience with various design tools if funds are restricted. 

Even if the application is fully functioning, it will not last long on the market if it does not comply with the most recent Ul requirements.

Designing Tools

During the development of an Android app, design components are created with programmes like Illustrator, Indesign, Sketch, and other prototypes and layout development tools and mobile animations development tools, which are just a few examples.

#3 Testing Skills

Before the final development of the app in Google Play or other platforms, Android application testing must eradicate errors, bugs, crashes, and other glitches. 

Testing the opportunity before launch will reveal some significant flaws such as payment errors, security flaws, etc. 

As a result, android developers must possess significant testing abilities.

Testing Methodology & Strategies

Testing is an integral part of quality assurance in the latest android apps. Before launching the project, Android app development demands a range of testing approaches and methods.

Developers should use the testing approaches listed below during the development phase.

  • OS testing 
  • Device testing 
  • Network connectivity testing 
  • Battery testing 
  • Security testing
  • Automated testing 
  • Testing tools 

#4 Publishing Skills

Publishing skills are just as critical as technical abilities. You won’t be able to obtain enough viewers no matter how excellent your Android app is if you don’t have enough and proper promotion. 

As a result, excellent publishing skills are required of android developers.

Marketplace Skills

To make an android app available to clients or internal employees, the app must be published at the end of the design and development phase. 

Developers should be familiar with the programming guidelines, submission, and design for Google Play submission. 

They must also have a sufficient amount of successful practical experience.

Documentation Skills

Android developers work with customers, technology products, and development methodologies.

Non-technical skills, such as producing all documents, articles, and blogs, are required of the developers.

Both experienced and inexperienced developers must write plans, and guidelines, examine, evaluate, and recheck.

#5 Project Management Skills

Regardless of their field of employment, the android developer is a component of the application development team.

Because a single person cannot do android app development, it necessitates the collaboration of a group of individuals with varying levels of expertise who can manage their respective domains. 

As a result, an android developer should be familiar with the necessary project management skills.

Research & Analysis Skills

App development aims to visualise and construct an app based on a notion. As a result, it is critical to conduct an extensive study on the topic and its marketability.

Before creating an app, the developer should think about the target audience, their needs, preferences, etc. 

Surveys and research can acquire all of this information from developers. This information assists the organisation in better understanding its clients. 

We are conducting the proper survey to obtain as much information about the clients as possible necessitates business analytic skills.

Internal Communication Skills

The Android development team consists of diverse individuals, ranging from designers to developers. Effective communication is required to keep the entire team on the same page. 

As a result, the developer must be able to communicate effectively and use tools to facilitate internal collaboration.

To ensure smooth communication, data and file exchange, video conferencing, and other tasks, use various data transfer methods. 

Team members can readily connect and find immediate solutions if necessary with appropriate communication.

How to make an android app for beginners?

How to use Android Studio as a Beginner

Android Studio is always becoming better. visit the Android Studio download page for the most up-to-date information on system requirements and installation procedures

Now let me give you the base i.e how to create a project page 

How to Create a Project page?

Create a new Android project for your first app in this stage. The text hello world is displayed on the screen of an Android Virtual emulator or actual device in this simple app.

Here’s how the app will appear when it’s finished:

To begin….

  • Open Android Studio.
  • Click Start a new Android Studio project in the Welcome to Android Studio window. 
  • Choose a Basic Activity (not the default). Next should be selected. 
  • Make a name for your app, such as My First App.
  • Make sure Java is selected as the language
  • For the remaining fields, use the default values.
  • Click the Finish button to complete the task.

After you’ve completed these steps, you’ll be able to use Android Studio to:

  • Creates the My First App folder in your Android Studio project. This is generally under your home directory in a folder called Android Studio Projects.
  • Construct your project (this may take a few moments). Android Studio makes use of the Gradle build mechanism. The build progress may be tracked at the bottom of the Android Studio window.
  • This command displays your project in the code editor.

How Do You Set Up Your Screen?

Several windows and panes may open when your project first opens in Android Studio. 

Here are some tips on how to change the layout of Android Studio to make it easier to get to know it.

  1. If a Gradle window is open on the right side, hide it by clicking the minimise button (—) in the upper right corner. 
  1. Consider resizing the pane on the left that shows the project folders to take up less space, depending on the size of your screen.

At this point, your screen should resemble the screenshot below in terms of being less cluttered.

How to Explore Project Structure and Layout

The upper left corner of the Android Studio window should appear like this:

Android Studio has created many files for you based on your choice of the Basic Activity template for your project. 

You may explore the hierarchy of your app’s files in various ways, one of which is Project view. 

Project view organises your files and folders to make working with an Android project easier.

Note – That this may not necessarily correspond to the file hierarchy! Choose the Project files view by clicking (3) to see the file structure.

  • To expand the hierarchy of app files, double-click the app (1) folder. (As shown in the screenshot, (1).
  • You can hide or show the Project view by clicking Project (2). You may need to go to view> Tool Windows to see this option.
  • Project > Android is the current Project view selection (3).

Below your app folder in the project> Android view, you’ll find three or four top-level folders: manifests, Java, Java (generated), and res. It’s possible that you won’t see Java (produced) immediately.

  1. The manifests folder should be expanded.

AndroidManifest.xml is located in this folder. When your Android app is executed, the Android runtime system reads this file, which describes all of the components of your programme. 

  1. Open the java folder and expand it. This is where you’ll find all of your Java language files. There are three subfolders in the java folder:

Com. example.myfirstapp: This folder contains the Java source code files for your app. 

(AndroidTest) com. example.myfirstapp: Your instrumented tests, which are tests that run on an Android device, should be saved in this folder. It starts with a simple test file.

(Test) com. example.myfirstapp: Your unit tests should be saved in this folder. To perform unit tests, you don’t require an Android smartphone. It begins with a rudimentary unit test file.

  1. Open the res folder and expand it.

This folder holds your app’s assets, such as photos, layout files, strings, icons, and styling. It has the following subfolders:

Drawable: This folder will hold all of your app’s images.

Layout: The UI layout files for your activities are stored in this folder. Your app currently has one training with a layout file named activity_main.xml. Content main.xml, fragment first.xml and the second.xml fragment are also provided.

Menu: Any menus in your programme are described in XML files in this folder.

Mipmap: The launcher icons for your programme are stored in this folder.

The navigation graph, which instructs Android Studio on navigating between different areas of your app, is stored in this folder.

Values: This folder contains resources used in your projects, such as strings and colours.

Create an Emulator ( Virtual Device)

In this, you will create a virtual device using Android Virtual Device Manager (AVD) that simulates the configuration for a particular type of Android Device.

Steps to create a configuration that describes in the virtual device:

1) Select Tools to click the AVD Manager icon in the toolbar.

2) Select Create Virtual Device at the bottom of the dialogue box.

3) Choose the virtual device definition as Pixel 2 & click next

4) Here, select the latest release or the recommended one. This doesn’t matter.

5) The Download button should be visible on the dialogue box. If not, there is a link to download in the suggestion box. When you’re finished, click Next. This could take a few minutes, depending upon your internet speed.

6) In the following dialogue box, click Finish.

AVD Manager now shows the virtual device you have added recently.

Note – System Images can take up a large amount of your disk space, so download what you need.

7) Close the dialogue box if it is still open.

The Final Step: Run your app on your new emulator:

1) In Android Studio, select Run Icon in the toolbar.

2) Select Device from the list of available devices in Run. Select the virtual device that you just configured.

After selecting the device, the emulator you have created starts and boots just like an android device. 

The progress at the very bottom is a small horizontal bar. Depending on your computer’s speed, this could take some time.

Messages that appear in the status bar
Gradle build running
Wait for the targeted device to turn on.
Installing APK
Launching activity
Source

Once your app is ready, Android Studio uploads the emulator and runs it. 

The emulator shows your app like this.

Java programming language is the base for android development. So I have provided the required tool for development. 

If you feel that Android is a bit difficult, try using these programming languages to create applications for Android Devices.

Best Programming Languages used for Android App Development

There is a wide range of programming languages available for android application development. These are the common languages used for development.

1) Java 

Sun Microsystems released it as a programming language and a computing platform. It is an open-source programming language that employs the C++ syntax, making it familiar and straightforward to learn for developers. 

Oracle Corporation now owns the company. Java is a programming language that includes both a compiler and an interpreter, and it runs on the JVM. 

The Java Runtime Machine is referred to as “JVM.”

Java is the most extensively used language due to its standing as the leading language for Android application development (which has since been superseded by Kotlin).

Java is the most widely used programming language in the Play Store, and it is also the most commonly supported.

Google has created a language. Aside from that, Java has a vibrant online community (support in the event of an issue)

2) Kotlin

Previously, Java was the official language for Android app development. However, since 2019, Google has proclaimed Kotlin the official language for Android app development. 

Instead of Java, Kotlin is a cross-platform language of programming that can be used to construct Android apps. 

It was also introduced as an alternative “official” Java language in 2017. The Java Virtual Machine runs Kotlin, which is a Java-like language.

The main significant difference is that Kotlin does away with some of Java’s irrelevant features, such as null pointer exceptions. It also gets rid of the comma at the ending of every line.

3) C++

The Android Native Development Kit can be used to develop Android apps in C++ (NDK). 

However, because an app cannot be entirely built in C++, the Native Development Kit (NDK) is used to implement elements of the app in native code. This makes it easier for the app to leverage code libraries as necessary.

While C++ can be beneficial for improving Android apps in certain situations, it is much more challenging to set up and less adaptable. It’s possible that as the complexity grows, so will the number of bugs.

As a result, Java is preferred over C++ because it does not provide enough benefits to compensate for the additional work necessary.

4) C#

C# is so comparable to Java. It’s excellent for developing Android apps. Garbage collection is implemented in C#, much like it is in Java, to reduce the risk of memory leaks. 

Furthermore, C# has a much simpler and clearer grammar than Java, making it easier to code.

C#’s disadvantage in the past was that it could only run on Windows platforms since it relied on the.NET framework. But on the other hand, Xamarin takes care of the problem.

5) CSS, HTML & JavaScript

The Adobe PhoneGap framework, powered by Apache Cordova, may be used to construct Android apps using HTML, CSS, and JavaScript. 

The phone gap framework essentially allows web developers to create hybrid applications shown using web view but packaged as mobile apps.

While the Adobe PhoneGap framework is adequate for basic Android app development tasks, it does not require much programming beyond JavaScript. 

6) Dart

Dart is an open-source programming language that underpins the Flutter framework, which is gaining popularity these days to produce beautiful and performant web, desktop, and mobile apps in less time. 

Dart’s main selling feature is that Google created it as a client-optimised language enabling rapid app development on any platform. 

Dart’s primary goal is to make UI creation easier for developers by including capabilities like hot-reload, allowing developers to observe changes in real-time while working on the app.

Dart is also well-known for its speed, compiling to ARM and x64 machine code for mobile, desktop, and backend applications. JavaScript is also used in web apps.

Creating a competent app takes a lot of effort. It’s best to choose one of the other languages on our list if you want to be an actual Android developer.
