Top 3 Fundamentals for Android App Development

Today there is a sharp and continuous rise in android app development. For beginners who are planning to develop or learn developing mobile apps, following are a few fundamentals.

1.  Master the Language:
In android apps Java and XML are the two main programming languages. Mastering these two languages is prerequisite to develop apps in android. If you want to develop a more elegant android app then you should fully master these two languages.

2. Knowledge Right Development Tools:
It is important or in fact inevitable to be fully familiarize with build automation tools. Other than that integrated development environment before you get started with developing the app. Tools like Android app studio IDE or the Eclipse can be used which can help in improving the code. Your tool of sets can include software like Apache Maven, Apache Ant and Gradle.

3. Application Components:
Application components are a very important part and basic building block of android app development. Each one of these application components is like a point from which the system can enter your app.

Your words are really good enough to understand about the Android app development. I have something more and fresh information about it only if you want to see.

Eclipse couldn't challenge Android Studio (AS) as it was designed differently at different times. App developers can use Eclipse for distinctive app development platforms or a group of different programming languages, but it couldn't adapt absolutely to the world of Android app development.

Android Studio is specific for Android only, which makes it superior in comparison with Eclipse. Hence, AS could be the best choice for the android app development, also, as you have penned up in your thread about application components; they should be clearly defined and adequately planned.

Each application has some cool features which draw the attention of the users and engage
them. The use of applications in the mobile phones has made our lives comfortable and
convenient. In fact it has drastically transformed the smartphones and their functionalities.
Android apps are no exception in this regard. There are developers and designers who are
working as a team in creating apps which can engage users in meeting their desired aims and
objectives.

If you want to excel as an Android app developer, given below are some basics or
fundamentals which you should consider before getting into the core programming of an
Android app.
These are:

Mastering the language: XML and Java are the two most vital languages which are used
for creating Android apps. So a strong knowledge of these two languages are very vital for
developing applications in Android platform.
There are some fundamentals for Java programming language which are given below:

•  Inheritance and interfaces


•  Packages


•  Objects and classes


•  Concurrency


•  Collections


•  Strings and numbers, generics

Familiarity with appropriate development environment and tools: Before starting with
your app development, it is very vital that you should make yourself familiarize with the
build automation tools along with the integrated development environment. For the tools
you can use Eclipse or Android app Studio IDE. This will definitely facilitate you in learning
the basics that can improve your code. This apart, by learning Gradle, Apache Ant and
Apache Maven which serve as strong tools you can seamlessly manage your builds.

Awareness over Android applications, fragmentations, threads, tasks and loaders:
The market for Android is segregated with multiple operating systems and devices. So, if
your devices supports multiple versions, then it will incur more testing, maintenance and
related costs. Also you will be needing relevant assets, fonts and layouts which will help in
availing superior experiences in accordance with the various screen characteristics.

Android apps can be made utilizing Kotlin, Java, and C++ languages. The Android SDK tools manage your code beside any information and asset documents into an APK, an Android package, which is a chronicle record with a .apk suffix. One APK document includes every one of the elements of an Android application and is the file that Android-powered gadgets use to introduce the application.

• The Android operating system is a multi-user Linux system in which each app is a different user. By default, the system assigns each app a unique Linux user ID. The system sets permits for all the files in an app so that only the user ID assigned to that app can access them.


• The Android system executes the principle of least privilege. That is, each app, by default, has access only to the components that it requires to do its work and no more. This creates a very safe environment in which an app cannot access parts of the system for which it is not given permission. However, there are ways for an app to share data with other apps and for an app to access system services: It’s possible to arrange for two apps to share the same Linux user ID, in which case they can access each other's files. To conserve system resources, apps with the same user ID can also arrange to run in the same Linux process and share the same VM. The apps must also be signed with the same certificate.


• An app can request permission to access device data such as the device's location, camera, and Bluetooth connection. The user has to explicitly grant these permissions. 

Android app development is the process of creating software applications that run on the Android operating system. Android developers are getting busy designing, and building apps of their own and embedding them with favorable features.

The top fundamental concepts that developers must understand include:

• Master the language


• Familiarity with the right application development tools and environment


• Knowledge of the application components


• Awareness of fragmentations, android applications, threads, loaders, and tasks


• Choosing the right tools

By mastering these fundamentals of Android app development, developers can create high-quality apps that meet the needs of users and provide a great user experience.
