The extraordinary features that come with the apps are the ones that grab the interest of the users. Apps make phones “smart”, and through their benefits, apps have radically changed today’s way we operate.
Expert programmers are busy designing and building their apps and embedding them with custom features. This article will cover the top 5 principles of Android app development that you should know before starting Android application programming.

Top 5 Android App Development Fundamentals
- Master the language
- Knowledge of the application components
- Awareness over fragmentations, android applications, threads, loaders, and tasks
- Choosing the right tools.
- Familiarity with the proper application development tools and environment
01. Master the language
Java and XML are the two major programming languages ​​used in Android app development. Therefore, expertise and knowledge in these programming languages ​​are a prerequisite for developing an Android mobile app. Some basic principles of Java programming language include:
* Packages
* Items and classes
* Inheritance and interface
* Strings and numbers, common
* Collections
A proper understanding of Java and XML will help you to create/develop a more robust and beautiful Android app.
02. Knowledge Of The Application Components
Applications are essential building blocks of Android app development. Each component has a different point through which the system can enter your app. Although each of them exists as its entity and plays a specific role, some depend on each other, and these are not all places of actual entry.
There are five different components of the app, each working with varying life cycles with another purpose that explains how it was created and destroyed. These include:
Activities:
Activities work together to create an integrated user experience in the app. However, each of them is free.
Content providers:
It is the component that manages the shared set of app data. With this component, the data that you store in the file system, on the web, can be queried or even edited from an SQLite database (unless the content provider allows it)Û” This component is also helpful for writing and reading data that is not shared and is private to your app.
Services:
It is a component that runs in the background to work on long-distance or long-term operations. It does not provide a user interface (for example, it can play music in the environment).
Activating components:
A synchronized message called Intent activates 3 of the four components (i.e. the recipients of services, activities, and broadcasts). Intentions bind individual members to each other at runtime, whether or not that component belongs to your app.
Broadcast Receivers:
It is the component that responds to broadcast announcements throughout the system. Most broadcast receivers start with the system. Although they do not display the user interface, they can create status bar notifications that alert users. In general, this is the gateway to other components, and it only works minimally.

03. Awareness Over Fragmentations, Threads, Loaders, Android Applications, And Tasks
If your device supports more devices and performances, it will require more maintenance, testing, and associated costs. The opposite is also true. It is third Android App Development fundamental.
It would help if you also had proper fonts, assets and layouts that will help ensure the best possible experience in the various features of the screen. You should also consider Android support sensors or UI features. All Android apps have one application class, one or more activities, and one or more pieces.
Sometimes, you may have services for background tasks that should run continuously, but other times you can’t. If you want an excellent and smooth user interface, always make sure the thread is never blocked.
Therefore, extended operations (calculations, I / O, network, etc.) should be synchronized in the background (mainly on a different thread of execution). That is why it is essential to learn Java language coordination facilities.
04. Choosing The Right Tools
The simple tools you need for Android app development are just a Mac or Windows PC, any Linux and Eclipse, ADT plugins, and Android SD, all for free. You can learn how to configure your development environment through the installation guide on Google.
It documents everything in Android App Development. There are some unique Android parameters that you should consider when writing an Android app.
05. Familiarity With The Proper Android App Development Tools And Environment
If you are stepping into Android app development, you must familiarize yourself with the Blood Automation tools and the integrated development environment before developing your app. You can use Android App Studio IDE or Eclipse for devices.
They will help you learn the basics and many other things that will help you improve your knowledge about coding. You can learn Apache Maun, Apache Ant and grids as they provide a robust set of tools to help you manage your construction.
It is also essential that you familiarize yourself with source control tools and concepts. Learn Gut and then create Gut Source Repository (by creating an account on Bit Bucket or Gut Hub).
To understand the basic concepts and terms of how the platform works, you can use the Gut Pocket Guide.
