How to build mobile apps

Interested in learning how to develop and design mobile applications but not sure where to start?

Let Continuing Professional Education guide you in understanding the basics of mobile platforms. Once you gain a general understanding of what you will need to know, enroll in one of our mobile development courses and start building your own applications.  

The increased use of smart phones has made mobile application development one of the most popular forms of coding. With the right instruction and enough practice, anyone can learn how to design and build applications.

Whether learning part-time as a hobby or full-time as a career, there are many perks of being a developer in the booming mobile application industry. Before learning how to program it is important to first understand the basics of how the applications are designed.

 

Application Development Overview

Mobile applications, or apps, are developed specifically for the mobile platform that they will be running on; typically either iOS or Android, as they have the largest user base.

The iPhone, iPad, and all other Apple product use the iOS platform. To develop an app on iOS, Objective-C, and Swift programming languages are used. An Integrated Development Environment (IDE) called Xcode, which can only be run on a Mac, is also used.

Android apps are developed with the Java programming language, an IDE such as Android Studio, and the Android Software Development Kit, which can be run on a Mac, PC, or Linux operating system are also required.

 

Developing with iOS vs. Android – simplifying the difference

  iOS Apple Android
Devices iPhone, iPad, Apple Watch, Apple TV Samsung, HTC, LG, & Moto phones, Android Wear Watch, Samsung Tablets, Smart TVs
Programming Language Swift or Objective-C Java or C++
Development Tools Cocoa Touch Android Software Development Kit
Integrated Development Environment (IDE) Xcode Android Studio, Android SDK

 

Both platforms offer similar development tools and require the same technical effort to design. Choosing to build on iOS vs. Android is generally based on preference and what language is most comfortable to the developer. Of course there are many benefits to learning how to develop on both platforms; however, those new to programming should first get comfortable with one platform before continuing on to the next.
