The appealing features that come with applications are what pique consumers’ curiosity. Apps make phones “smart,” and thanks to their advantages, they have fundamentally changed how we live today. Expert programmers are working hard, creating and constructing their programmes, and adding useful features. The top 5 app development concepts for android developers in India should be understood before starting an android app development. Read this article further.
- Learn the language.
- Knowledge of the appropriate environment and tools for application development
- Understanding the elements of the application
- Understanding of fragments, android applications, threads, loaders, and tasks
- Choose the appropriate tools.
Android App Development Fundamentals
- Learn the Language
Java and XML are the two primary programming languages utilized in Android app development. For this reason, learning and mastering these programming languages essential requirements for creating Android applications. The following are a few Java programming language fundamentals:
- Packages
- Classes & objects
- Interfaces & Inheritance
- Integers and strings, generics, and collections
- Concurrency
You can build/develop a more reliable and beautiful android app with a proper grasp of Java and XML.
- Knowledge of the Appropriate Environment and Tools for Application Development
Before you begin building your app, you must get comfortable with the build automation tools and the integrated development environment if you are new to Android app development. You may study the fundamentals and many other things that will help you better your code by using the Android app studio IDE or Eclipse as your tools. You should get familiar with Apache Maven, Apache Ant, and Gradle, as they provide a robust set of tools to assist in managing your builds.
It would help if you also got acquainted with the terms and technologies used in source control. Create a git-source repository after you have learned it (by creating an account on Bitbucket or GitHub). You may utilize the Git Pocket Guide to get a handle on the fundamental ideas and vocabulary of how the platform works.
- Understanding of Application Components
The fundamental building blocks of developing Android apps are application components. Every part is a distinct entry point for the system into your program. Even while each is independent and fulfills a particular function, some are dependent on one another, and only some serve as genuine entrance points.
The five primary sorts of app components each have a unique function and life cycle that specify how they are produced and deleted. They consist of the following:
- Activities
A single screen with a user interface is represented by this component, which is used for activities (for instance, an email app may have one training showing a list of new emails, another activity composing emails, and another reading email.) The app’s activities come together to provide a seamless user experience. However, they are all independent.
- Services
This is a background-running component that does work for other processes or lengthy tasks. There is no user interface offered (for instance, it might play music in the background while the user is in a different app).
- Suppliers of Content
This component manages a standard collection of app data. This fundamental enables you to query and even modify the data you save on the web, in an SQLite database, or in the file system (as long as the content provider allows). Additionally, this component is your hand for writing and accessing data that is private to your app and is not shared.
- Receivers of Broadcast Signals
This device reacts to system-wide broadcast messages. Most broadcast receivers are system-generated, and even though they lack a user interface, they may generate a status bar notification to inform the user when a broadcast event occurs. Typically, it does minimum labor and is a gateway to the other components.
- Constituting Elements
Three of the four components are activated by an intent message sent synchronously (i.e., services, activities, and broadcast receivers). Whether the component is a part of your app or not, intents may also tie different elements to one another during runtime.
- Understanding Android Applications, Fragmentations, Threads, Loaders, and Tasks
With several different devices and operating system versions, the Android market is fragmented. Remember that your gadget will need additional testing, maintenance, and maintenance expenditures if it supports more devices and versions. The opposite is also true. Additionally, it would help if you had the proper layouts, assets, and fonts to provide the most incredible experiences across the range of screen characteristics. It would help if you also considered Android’s various supporting sensors or UI features. An application class, one or more activities, and fragments are standard features of all Android applications.
You may sometimes have services running continually for background activities, but occasionally you may not. Make sure that the thread is always allowed if you want to create a fantastic and seamless user experience. As a result, all lengthy activities (including calculations, I/O, network, etc.) should be carried out in the background asynchronously (mainly on a different thread of execution). For this reason, it’s crucial to understand the Java language’s concurrency features.
- Choosing the Correct Needed Tools
You need a Mac or Windows computer, a Linux distribution of your choice, Eclipse, the ADT Plugin, and the Android SDK, all of which are free. To discover how to set up your development environment, read the installation guide on Google; it offers documentation for every step required. You need to consider specific Android requirements when developing an Android app. Some of them consist of the following:
- Performance and Responsiveness
The operating system will ANR if you don’t reply to user interaction within five seconds. The only choice you will have is to forcibly shut your app if your application is ANR (application not responding).
- Users Will Experience Delays Of Greater Than 100 Milliseconds
The UI thread should always be continued since there is only one of them, as was already explained.
- Scarce Resources
Use wake-locks (the mechanism that compels the device to do a specific action despite the battery manager’s advice to put it to sleep) sparingly. Avoid needlessly checking hardware (such as the accelerometer or GPS) since doing so would rapidly drain the battery.
Conclusion
Today, 77% of Americans possess a smartphone, and most of their time is spent using applications. In reality, 197 billion applications were downloaded in 2017, making an occupation as an Android Developer in India solid and full of prospects for advancement. There is a lot to learn about Android App development, so consider starting with Simplilearn’s Google-approved Certified Android App Developer training course. As you design six popular apps throughout the course, you’ll get practical experience and learn how to understand the foundations of Android, along with the other skills you’ll need. The programme is designed to prepare students for Google’s Associate Android Developer (AAD) Exam. Happy building apps!
