It is one of the strong reasons which motivate a lot of youngsters to know of an Android Course in Delhi quite enthusiastically.
Android Development
Android development is the process by which applications are created for devices running the Android operating system. Google states that "Android apps can be written using Kotlin, Java, and C++ languages" using the Android software development kit, while using other languages is also possible.
Android is a global mobile market share, this market leadership implies high job security for Android developers. As Android app development continues to connect people across the globe and enable the user to engage more innovatively and interestingly, a career in Android development has become ever more enriching, fulfilling, and in-demand to the global economy.
To be a successful Android app developer, you need to develop many skills and apply them in space and time to provide the best experience to your users. Apps make phones smart and through their benefits, apps have significantly changed how we act today. Skilled programmers are getting busy, designing and building their own apps and embedding them with friendly features. If you are one of those enthusiasts, here are some Android App Development Fundamentals that you should know before start Android App Programming.
To become a successful Android app Developer you need to acquire some of the essential skills. These are mentioned below-
1) Master the Programming Language
Java and XML are the most important programming languages used in Android app development. Therefore, knowledge and proficiency in these programming languages are prerequisites for developing an Android app. Some fundamental of the programming language are its pillars, including packages, objects and classes, inheritance and interfaces, strings and numbers, generics, collections, and constructs.
2) Using accurate App Development Tools and Environment
It is important to be familiar with build automation tools and Integrated Development Environment (IDE) to develop Android apps. The Android App Studio IDE or Eclipse for the tool will help you get the basics and many other things that will help improve your code. Apache Maven, Apache Ant, and Gradle are easy to learn as they provide a powerful set of tools to help manage these builds.
It is also important that you familiarize yourself with the source control tools and concepts. Ascertain Git and create a Git-source repository. To understand the basic concepts and terms of how the platform operates, you can use the Git Pocket Guide.
3) Application Components Knowledge
There are five different types of app components each serving a well-defined purpose with a distinct life cycle which defines how it is created and destroyed.
· Activities- It represents a single screen with a UI such that an email app can have an activity that shows a list of new emails. The activities work together to create a coactive user experience in the application. However, each of them is independent.
· Service- The component runs in the background to perform work for remote processes or long-running operations. It does not provide a user interface such as a music player in the background while the user is in a different app.
· Activating components- A contemporary message applied as an intent activates 3 of the 4 components. Intentions also bind different components to each other at runtime whether the component relates to your app or not.
· Content providers: The application manages a shared set of data, the data that you either store in the file system, on the web, an SQLite database can be queried or modified until the content provider allows it. It is useful for writing and reading data that is not shared and is private to your app.
· Broadcast receivers: System-wide broadcast announcements originate from most broadcast receiver systems, and although they do not display a user interface, they can create a status bar notification that alerts the user when a broadcast event occurs. Generally, it is a gateway to other components and does only minimal work.
4) Awareness over Android Application and Tasks
Android is a fragmented market with many different devices and operating system versions. Appropriate fonts, assets, and layouts will help ensure that the various screen features deliver the best possible experience. You should also consider the array of Android-supported sensors or UI features.
All Android apps have an application class, one or more activities, and one or more pieces. Work should be done for background tasks that must run continuously but at other times you cannot. For a smooth UI, always make sure that the thread is never blocked. Therefore, long operations (compute, I / O, network, etc.) should all be run asynchronously in the background (mainly on a separate thread of execution). This is why it is important to learn the computer features of the Java language.
5) Right Choice over Needed Tools
The tools for Android app development demand just a Mac or Windows PC, any type of Linux, and Eclipse, ADT plugins and Android SDK — all of which are free. Through the installation guide at Google to set up your development environment; provides all the necessary documents. There are some unique parameters of Android that you should consider when writing an Android app.
· Performance and responsiveness- Always respond to user input within five seconds otherwise the operating system will give you the ANR. (ANR-application not responding – the only option that you will have is to force close your app.)
· Lags of more than 100ms will be noticed by the users- The UI thread should never be blocked because it is only one.
· Limited resources: Wake-locks should be used sparingly. Do not unnecessarily poll hardware (e.g. GPS or accelerometer) because it will quickly run down the battery.
EndNote-
Android upgrades day by day with the changing technology needs. So your career never ever stops learning the new technology. And, every new technology needs to be experiment with by you to understand it well.
