Apps are popular because of the cool features they offer. Apps are smartphones and have revolutionized how we live today. Programmers are becoming more skilled in creating and building their own apps and embedding them to have positive features. This article will discuss the 5 most important Android App Development fundamentals you need to know before you start programming an Android app:
1. Learn the language
Java and XML are two of the main programming language that is used in Android App Development. To develop an Android app Development, you must have a good understanding of these programming languages. The following are some of the basics of Java programming language:
Packages
Objects and classes
Interfaces & Inheritance
Strings & numbers, generics,
Collections
Concurrency
A solid understanding of Java and XML can help you develop/build a robust and elegant Android app.
2. Be familiar with the right tools and environment for application development
Before you begin developing Android apps, you should familiarize yourself both with the build automation tools and the integrated development environment. For the tools, you can use Eclipse or Android app studio IDE. They will teach you the basics and help you improve your code. Gradle, Apache Ant, Apache Maven, and Gradle are all available to you. They provide powerful tools that will help you manage your builds.
3. Understanding the Application Components
App components are the core building blocks of Android app development. Each component is an entry point for the system to your app. Each component is an entity that exists independently and serves a specific purpose. However, they all depend on one another and are not all entry points.
Five types of components are available for the app development company. Each has a unique purpose and a different life cycle that determines how it is created or destroyed. These are:
Activities:
This component represents a single screen that has a user interface. For example, in an email app, one activity may show a list and other activities can compose emails. Another activity might be reading emails. The app's activities work together to create a seamless user experience. Each one is however independent.
Services:
This component runs in the background and performs work for long-running or remote processes. It doesn't provide an interface for the user
Content providers:
This component manages a shared set of app data. This component allows you to store data in the file system or on the internet. SQLite Database can be accessed and modified. This component can also be used to read and write data that isn't shared with your app.
Broadcast receivers :
This component responds to broadcast announcements from the entire system. Although broadcast receivers are not able to display an interface, they can set up a status bar notification to alert the user whenever a broadcast event occurs. It is generally a gateway to other components and does little work.
4. Awareness of Fragmentations, Android Application Threads, Loaders, and Tasks
Android is a fragmented marketplace with many devices and operating systems. You should note that if your device supports multiple versions and/or devices, it will require more maintenance and testing. This is in addition to the associated costs. It is also true that vice versa. A proper font, asset, and layout will be required to ensure that you get the best experience on the different screen sizes. Also, you should consider the various android-supported sensors and UI features. You may have background services that need to run constantly, but for others, you might not. You must ensure that your thread does not get blocked if you want to provide a smooth and beautiful user interface. It is therefore important to be familiar with the Java concurrency facilities.
5. Make the right choice over the necessary tools
You only need a Mac or Windows computer, any Linux version, Eclipse, the ADT Plugin, and the Android SDK to develop Android apps. All of these tools are free. To learn how to set your development environment, you can consult the Google installation guide. It provides detailed documentation. When creating an Android app, there are some specific parameters you need to consider. These are some of the parameters:
