The Duties for a Mobile App Development Coding Job

By Nikhil Abraham

If you are hoping to find a job in coding, you might want to consider mobile app development. Mobile application developers create applications that run on cellphones, tablets, and other mobile devices. Mobile applications can be more challenging to create than browser‐based websites because users expect the same functionality on a device without a dedicated keyboard and with a smaller screen.

In 2014, users purchased and spent more time on mobile devices than traditional PC desktops, marking a major milestone and the continuation of a trend years in the making.

Users today prefer to download and use native mobile applications from an app store, though it is possible to create mobile optimized websites that run in the browser using HTML, CSS, and JavaScript.

The two most popular app stores are the Apple App Store, which hosts apps for iOS devices such as iPhones and iPads, and the Google Play Store, which hosts apps for phones that tables running the Android operating system. Developers code apps for iOS devices by using the Objective‐C and Swift programming languages, and code apps for Android devices by using Java.

Objective‐C, which was invented in 1983, is traditionally and currently used to create iOS apps. Swift is a new programming language created by Apple and released in 2014. This programming language was designed from the ground up as a replacement for Objective‐C.

Mobile developers are in high demand as mobile usage overtakes browsing on traditional PCs. In addition to creating apps, employers also value these skills:

  • Location services: The service most frequently integrated into and used in mobile applications is location. Maps, reservation, and transportation applications all become more useful when they take into account our current location. However, location services consume battery life rapidly, although specialized techniques can reduce battery drain. Mobile developers who understand these techniques will have a leg up on the competition.

  • Application testing: The number of devices that a mobile developer has to consider is staggering. In addition, an errant line of code can cause a mobile application to not install correctly or to leak memory until the application crashes. Mobile application testing software automates the process of testing your application across a variety of device types, saving a huge amount of time and a drawer full of phones. Mobile developers who can integrate testing software such as Crashlytics into their applications will get the data needed to continuously improve their application code.

Mobile application developers work with designers to create easy and intuitive mobile experiences, with back‐end developers to ensure that data submitted by or received from the phone is in sync with data on the website, and with product managers so that the application launches smoothly.
