Android Apps Development: Fundamentals and Important Rules

The cool features that come with the android apps are what attract the attention of users. Android apps make phones smarter and by using their benefits, apps have dramatically changed the way we work today. Adept program planners are busy, designing, and building their own programs and embedding them with great features. If you are one of those loved ones, here are some basic tips for Android app development that you should know before you start an Android app.

1. Master the Language

Java and XML are two programming languages ​​used in Android app development. Knowledge and control of these programming languages, therefore, is a requirement for designing an Android app. Some of the basics of the Java programming language include:

  • Packages
  • Objects &classes
  • Inheritance and interfaces
  • Strings and numbers
  • Collections
  • Concurrency

Proper understanding of Java and XML will help you build/improve a strong and beautiful Android app.

2.Knowledge of Application and Environmental Development Tools

When you get into Android app development, it is very important that you familiarize yourself with the automation tools and integrated development environment before you start making your own app. You can use the Android app studio IDE or Eclipse with the tools; will help you learn the basics and many other things that will help you improve your code. You can learn Apache Maven, Apache Ant, and Gradle as it offers powerful tools to help manage your build.

It is also important that you familiarize yourself with the source control tools to manage resources and concepts. Read and create the repository for the source (by creating an account on Bitbucket or GitHub). To understand the basic concepts and principles of how a platform works, you can use the Pocket Guide.

3.Application Components Information

App components are important components of the Android app build. Each item has a different point through which the app can access your app. While each exists as its own organization and plays a role, there are others that are dependent on each other and not all real entry points.

There are five different types of items each app works for a different purpose with a different life cycle that describes how it is made and damaged.

Android Apps Activities:

This is a segment that represents a single screen with a user interface (for example, an email application may have one function that displays a list of new emails, another function that includes emails, and another that reads emails). Tasks work together to create an integrated user experience in the app. Still, each one is independent.


This is the part that runs in the background to perform remote process work or remote operation. It does not provide an interface (for example it may play music in the background while the user is in a different app).

Content providers:

This is the part that handles the shared set of app data. With this element, the data you store in the file system, on the web, the SQLite database can be a query or modified (as long as the content provider allows it). This item is also useful for writing and reading unverified and private data in your application.


This is the part that responds to the announcements of a wide distribution of the program. Most broadcast receivers are from the system, and although they do not show the user interface, they can create a status bar notification that alerts the user in the event of a broadcast event. Usually, it is a gateway to other things and does little work.

Active components in Android Apps:

The so-called synchronization message intentionally activates 3 of the 4 elements (e.g. services, tasks, and broadcast receivers). Aims and binds individual items at a later stage whether the component belongs to your app or not.

4.Awareness, Android Apps, Threads, Loader, and Tasks

Android is a separate market with many different devices and types of android apps. Note that, if your device supports multiple devices and/or types it will require additional care and testing, and related costs. The opposite is also true. You need the right fonts, materials, and structures that will help ensure that the best experience on the various aspects of the screen is provided. You should also consider the collection of Android sensors or UI resources. All Android apps have an app category, one or more functions, and one or more pieces.

In some cases, you may have background services that should go on continuously but sometimes you may not. If you want to bring a nice and smooth interface, always make sure the thread is not blocked. Therefore, the long-distance operation should all be run around the back (especially with a separate performance cord). This is why it is important that you learn Java language structures for concurrency facilities.

5.Making the Right Choice With the Needed Tools

The simple tools you need for Android apps development are just a Mac or Windows PC, any Linux version, and Eclipse, ADT Plugin, and Android SDK – all for free. You can go through Google Installation Guide to learn how to set up your development environment; provides documentation of everything you need. Android has different parameters to consider when writing an Android app. Some of these include:

Performance and Response in Android Apps:

You must always respond to user input within five seconds otherwise the app will allow it. (The ANR application is not responding – the only way you will be forced to close your application.)

Lags over 100ms will be visible to users:

As mentioned above, the UI thread should not be blocked because it is only one.

Limited resources:

Wake-locks (a method that forces the device to do something without the device’s battery sleep recommendation) should be used sparingly. Do not unnecessarily test the hardware (eg GPS or accelerometer) as it will speed up the battery.
