Intro to Mobile App Development

Smartphones and apps are an essential part of our lives nowadays, but how are mobile apps developed? Far from the days when the cell phone was just a device the size of a brick that made phone calls. Android and iOS have had a huge impact on the way we look at mobile technology. We essentially carry computers around, and the internet of things – devices with internet function – is only growing. If you learn how to develop mobile applications, you have control over both the controls of the phone and the devices with which they interface.

Intro to Mobile App Development

Mobile app languages

Just like desktop programming, mobile devices use programming languages ​​to write code for app programming. These include:

  • Android SDK tools and Java
  • Swift by Apple
  • Objective C

Android Programming

Android, a project from Google, is a Linux-like environment running a special version of Java. Therefore, if you have learned to code Java for your desktop or for web development, your skills will be transferred. Because Android devices have special tools and features that are not standard from one phone to another phone, and due to processor limitations, not all Java functions available for a desktop computer are available.

Most mobile processors are designed to run the Android embedded operating system; However, there are some larger devices that can run extended functions. Some other Android-specific Java features are added to support portable device features such as gravity sensors, accelerometers, and other built-in sensors, as well as call features.

Android SDK

The Android SDK is released for free by Google and is the set of Java code that is specific to the Android device. The features are made available by device and version, so you have to consider what features they add to their program. An Android app exclusively written for Android 5.0 will exclude lots of devices right now, as people continue to use phones and tablets with older versions of Android that do not support new code. Reverse compatibility with older Android versions is a very important factor when developing an Android app if you want the widest user base possible.


Developed for the extremely wide range of Apple products, IOS is Apple’s mobile operating system. Like Android, there are several versions, though Apple is better at systematic upgrading than Android because Apple is a company while Android devices are produced by a large number of companies. iOS apps are designed to run on almost any of Apple’s devices, from iPhone to iPad to MacBook Air and desktop environments. The fact that Apple controls product development means that reverse compatibility development is less of a problem.


Swift is developed as an iOS-specific version of Object C and is the original programming language for the iOS platform. Here again, if you learned C or C ++ for the desktop environment, a large amount of syntax will be transmitted. However, the libraries are custom to the Apple family’s products and are designed to support an event-driven program that benefits from sensors and other features of Apple devices

Objective C

Objects originally developed in the 1980s Objective C is the parent language that gave birth to Swift. Apple chose it to write earlier versions of iOS and OS X because it has the capability of Smalltalk-like features. Basically, Smalltalk allows a greater degree of interaction between the user and the device. To be able to use Objective C on other systems, one must omit the cocoa and cocoa touch library which is the root of iOS systems. Because of its large object structure, legacy and ability to write robust applications, many people write iOS C applications in objective C rather than Swift. It is necessary to know the limitations of the operating system and use it to program Cocoa as well as other Apple extensions specifically in Objective C for iOS.

iOS Programming on Windows

Although unofficial, developers who program in a Windows environment that previously could only write Objective C for a device can now write Swift in a Windows-programmed environment. This means that if you write apps that are available for both Apple and Android devices, there is no need to write code on two separate computers, which reduces costs. Swift for Windows became available as an unofficial port in mid-2016 and removed a bar for development. A Visual Studio add-on is now available to support Swift in the Visual Studio market.

Ways to learn App Development

One of the best places to start, in addition to the tutorials available on this site, is, which is the official site of the Android operating system and its development. From there you have access to education, self-study and a forum where you can talk to other people. You should also consider an IDE such as Eclipse that lets you program Java and run and troubleshoot your applications all in the same application.

In addition to these, you can learn the root code like Java or Object C on a variety of websites that offer web-based education in different languages. Once you understand Java, Android is within easy reach. When you master Objective C, it’s easy to switch to the Swift syntax.

Apps are a hot commodity and the popularity of some waxes and wanes. If you write the right app at the right time, you can have an app so popular that it is downloaded to devices like Facebook or YouTube app. Be sure to read our tutorials on the languages ​​that make up mobile device programming and explore your options for learning Java, Object C, and Swift. If you finding the BEST places to start learning, then Android training in Chandigarh is the best option for you.
