Top 5 Android App Development Fundamentals for Beginners

Android has quickly become the dominant smartphone OS on the market. People were compelled to develop a user-friendly OS with the widespread adoption of smartphones. Android is designed to be used with minimal instruction.


As soon as it was released, Android enjoyed a meteoric spike in popularity. Because of this, many software development company Houston have taken up the study of android app development. The use of android app developers is becoming increasingly popular among organisations and brands. Many would rather figure it out and improve upon it on their own. This is due to the widespread misconception among brands that building an android app requires in-depth knowledge of their industry. Only those who have deep ties to the brand will be able to pull this off effectively.

Creating an Android app? We’ll get into the nuts and bolts of it here. As such, let’s not waste any more time and get started.

To begin, it’s helpful to briefly define what an android is.

What is Android?

Android is a mobile operating system created by an open-source software engineering community (mostly Google and Open Handset Alliance). The OS was developed with a variety of languages, including Java (User Interface), C (Core), C++, and others.

Android is based on tweaks to the Linux Kernel, making it a Unix-like system. It is intended for use with touchscreen mobile devices. The first Android smartphone, which was revealed in November 2007, did not become available to the general public until September 2008.

Since 2011, Android has dominated the smartphone OS industry, and since 2013, it has controlled the tablet OS market. Every month, more than 5 billion devices around the world access the operating system.

Android App Development Fundamentals

When developers or users have a solid grasp of the core concepts underpinning app development, creating an Android app is a breeze.

Here, we will examine the rudiments of creating apps for the Android platform. We’ll go through everything from the basics of app creation to the skills you’ll need to build an app to the perfect design and development of an Android app from start to finish.

1. Master the Language

As the principal programming languages for Android app development, Java and XML are frequently used. As a result, designing a great Android app demands fluency and competence in these languages. The following are some of the principles of the Java programming language:

  • Packages
  • Objects & Classes
  • Inheritance & interfaces
  • Strings & numbers, generics
  • Collections
  • Concurrency

A better Android app can be developed with the help of knowledge of Java and XML.

2. Familiar with the Right Development Tool and Environment

Before you begin assembling your project, you should become acquainted with the unified development environment and the build automation tools. You can build an Android app using the Eclipse IDE or an Android device, which will teach you the ins and outs of the platform and provide you with access to a range of tools for refining your code.

Understanding Apache Maven, Apache Ant, and Gradle will provide you with a robust toolkit for controlling your build.

Spend some time researching source control, including the various tools and techniques used. After understanding git, create a GitHub repository for your code (by creating an account on Bitbucket or GitHub).

3. Knowledge of the Application Components

In Android app development, application components are crucial. Your app’s system can enter any of its many components.

While each element is distinct and serves a purpose, some depend on others, and not all of them serve as genuine entryways.

There are five separate classes of application parts, each of which fills a specific niche and has its unique production and disposal schedule. You may count on them to include:

Activities:

An activity is a representation of a single user interface screen (for example, an email application may have one activity showing a list of new emails, another activity composing emails, and another one reading emails). Because of the activities within the app, all of the app’s features come together to produce a coherent whole.

They are, nevertheless, entirely distinct creatures.

Services:

Services are components that work in the background to complete tasks for other, more distant processes or procedures that take a long time to complete. Inadequate user interface (for example it may play music in the background while the user is in a different app).

Content providers:

Content providers manage a centralized database that is accessed by numerous applications. You can read from, write to, and otherwise interact with data saved in an SQLite database, the cloud, or your local file system with this module (as long as the content provider allows it). This capability is handy for both creating and reading non-public data that is only accessible within your app.

Broadcast receivers:

This system component is in charge of responding to system-wide broadcast messages. Even though most broadcast receivers start at the system level, they can nonetheless notify the user of a broadcast event by posting a notification in the status bar. This section mostly serves as an entry point to other sections and performs very little on its own.

Activating components:

The intent is a single synchronous transmission that triggers three of the four phases (i.e. services, activities, and broadcast receivers). Intentions bind to each other during runtime regardless of whether the two components are directly related to your application.

4. Awareness of Fragmentation, Android Apps, Threads, Loaders, and Tasks

Android is a competitive marketplace with numerous device and operating system versions.

It should be noted that if your gadget supports additional devices and/or versions, it will undoubtedly necessitate more maintenance and testing, as well as the associated costs. The converse is also true. You will also need proper fonts, images, and layouts to ensure that the greatest potential experiences are provided in the various screen quality. You should also evaluate the variety of Android-supported sensors and UI features. Every Android app has an application class, one or more activities, and one or more fragments.

Background task services may or may not be required to run continuously in various instances.

If you want to express an outstanding and fluid UI, make sure the thread is never blocked.

As a result, large operations (calculations, I/O, networks, etc.) must all be executed asynchronously (usually in distinct execution threads) in the background. This is why it is critical to becoming acquainted with the Java language’s concurrency features.

5. Making the Right Choice over Needed Tools

All you need to create an Android app is a computer running Mac OS X or Windows, any Linux distribution, the Eclipse IDE, the ADT Plug-in, and the Android Software Development Kit (SDK), all of which are free. If you need assistance setting up your development environment, the Google installation guide contains thorough instructions. There are a few unique needs to keep in mind when developing an app for Android. As an example:

Effectiveness and speed: If you continuously wait more than five seconds to respond to user input, the operating system will ANR you.

Users will grow irritated if there are delays of greater than 100 milliseconds. Because the user interface thread is the sole one, it should never be stalled.

Constrained means: Wake-locks (a feature that keeps the device from sleeping when the battery management recommends otherwise) should be used sparingly to save battery life. To save battery life, avoid superfluous hardware polling (such as the GPS or accelerometer).
