Basics of Android App Development for Novices

Basics of Android App Development for Novices – An operating system called Android was primarily created for mobile devices. It is created by Google and is based on the Linux Kernel and other open-source technologies. It is used for mobile devices with touchscreen interfaces, such as smartphones and tablets. However, they are presently used in Android Auto automobiles, TVs, watches, cameras, etc.

It is now among the most widely used mobile operating systems. The Android operating system was developed by Android Inc., a company that Google purchased in 2005. On Android, a variety of programs (apps) are created for mobile cell phones, including games, music players, cameras, and others.

Android: What is it?

Several developers created the mobile operating system known as Android (mostly Google and Open Handset Alliance). The operating system is written in several languages, including Java (UI), C (Core), and C++.

The Linux Kernel has been updated to create Android OS, which is a member of the Unix-like OS family. It is mainly made for touchscreen mobile devices like smartphones and tablets. The first commercial Android smartphone was introduced in September 2008 after its announcement in November 2007.

Basics of Android App Development

When developers or app development aficionados are completely aware of the underlying ideas that underlie app development, creating Android apps becomes simple.

Languages for Programming Android

Since without the Android programming language, nothing is possible, we’ll start there. Three main languages may be used to create Android applications. They are XML and Java or C++. The back end of the program is written in an XML markup language, while the front end is written in Java/C++. Recently, Java and C++ have been replaced by a new language called KOTLIN. Let’s quickly review these languages.

The object-oriented programming language Java is built on classes. One of the reasons it is recommended for Android app development is because it is designed to function with the fewest number of dependencies possible. The general-purpose programming language JAVA was created to allow programmers to create code once and execute it elsewhere (WORA). This implies that any platform that supports JAVA may execute compiled JAVA code.

  • C++

Another language that may be used to construct applications is C++. A general-purpose programming language is C++. C++ made its debut in 1985. The language has undergone several revisions over the years, and the current version of C++ is functional, object-oriented, and general.

  • XML

Extensible Markup Language (XML) is a specification of rules for encoding texts in a manner that is both machine and human-readable. XML was created with simplicity, universality, and internet usability in mind.


KOTLIN is a general-purpose, cross-platform programming language that was created with JAVA in mind. KOTLIN originally launched in 2011, and Google declared it to be their preferred programming language for Android App developers in May 2019.

Making the Best Decision Regarding Required Tools

You just need a Mac or Windows computer, a Linux distribution of your choice, Eclipse, the ADT Plugin, and the Android SDK, all of which are free. Read the installation guide on Google to learn how to set up your development environment.

It provides documentation for each step needed. When developing an Android app, you need to take into account certain specific Android requirements. Some of them consist of:

  • Performance and responsiveness: The operating system will ANR you if you don’t reply to user interaction within five seconds. The only choice you will have is to forcibly shut your app if your application is ANR (application not responding).
  • Users will experience delays of greater than 100 milliseconds: The UI thread should never be stopped since there is only one of them, as was already explained.
  • Scarce resources: Use wake-locks (the mechanism that compels the device to do a certain action despite the battery manager’s advice to put it to sleep) sparingly. Avoid needlessly checking hardware (such as the accelerometer or GPS) since doing so would rapidly drain the battery.


In reality, 197 billion applications were downloaded in 2017, making an occupation as an Android App Developer one that is solid and full of prospects for advancement.

Consider beginning with Simplilearn’s Google-approved Certified Android App Developer training course if you want to learn all there is to know about developing Android apps on this Android App Development guide.

As you design six popular apps throughout the course, you’ll get practical experience and learn how to understand the foundations of Android along with the other skills you’ll need.
