[EXPERT OPINION]: Top 7 Technologies that you should know to become a mobile app developer

0

The Industry for mobile application development continues to grow as mobile devices become the centre of communication and work. Business and technological development have emerged at an impressive rate, causing an increased demand for an experienced mobile application developer.

A view of mobile app developer's world.

A must for an app developer

Developers need to work on different technologies, depending upon the different platforms available.

First, you need to decide on which platform you want to make an app like Android, iOS or both.

Secondly, I suggest these 7 Technologies that every mobile app developer should know, latest as of 2019:

1. JAVA

Java is the language that underpins all Android Development.

For those who have gained most of their coding experience in a language like Javascript, there can be a learning curve when picking up java for the first time. Java, like javascript, is object-oriented but it is also stricter about the way it handles data types.

App developers have to be much more thoughtful with their code, defining the types of data their applications plan to work with and more carefully allocating scarce memory resources.

2. kotlin

The recent surge in the demand of Kotlin programmers can be evident in the fact that some leading apps have migrated from Java to Kotlin.

Top companies such as Uber, Pinterest, Evernote, and Square have shown faith in Kotlin programming language. Even developers and App companies are loving Kotlin for its high compatibility with Java and Objective C and excellent tooling support.

And since both Android and Kotlin are backed by Google, the combination perfectly favours Android App Development process.

3. swift

Swift is the programming language Apple created specifically for developing their apps. This is the language of all the future development for iOS.

So you to know it! Our own app developers acknowledge that it’s not a small language, but you don’t have to know everything to land a junior position.

What you will need to do is make sure you’re comfortable with:

  • Basic syntax
  • Control flow
  • Optionals
  • Classes & Inheritance
  • Error handling

4. API

As an app developer, you’ll likely want to interact with many other services. For example, you may want to allow your users to access a calendar from a third party service or check the stock market. Many companies offer APIs and will tell you exactly how to query them for data in a consistent, secure way.

While you’re free to interact with any existing API, Google also makes it very easy to connect to their own APIs from your Android app.

For example, you can easily use Google APIs to monitor the location of your users, let them search for local places, and reference a map from within your application. You’ll want to get comfortable exploring the nuances of different APIs and recognise that no two APIs are exactly alike.

5. database

If your app handles large amounts of data, most of it probably won’t live on your device at any given time. Instead, your app will likely interact with a database living outside of your phone.

Cloud services like Firebase or Parse provide simple APIs to store data in the cloud and make it available across devices. These platforms also often provide Java libraries that you can plug into your app, making it easy to cache some of the data on the user’s device.

This syncing of data between local storage and remote database is important if you want to let users use the app when they’re offline.

Another way to store data locally is through Android’s built-in support for using SQL to interact with an SQLite database.

However you choose to handle data in your application, you’ll need to explore and understand how databases work, and the ways to query that data and use it in your app.

6. react native

It’s an open-source platform maintained by Facebook and a large community. It uses JavaScript to create apps for iOS and Android. It is worth mentioning that React Native uses native UI elements, making RN-based apps look and behave like native iOS and Android ones.

A lot of big companies like Tesla, Walmart, and UberEats are developing apps using this technology. Facebook, Instagram and Zynga also integrated some React Native features into their existing apps.

It means that RN, despite some opinions, is a good choice not only for simple apps but also for more advanced ones. Still, it’s true that RN is the best solution for small/medium apps targeted at both platforms where heavy computations are moved to the server-side.

7. flutter

Google’s Flutter is a mobile app SDK used for developing high-quality native interfaces on Android and iOS.

This framework was launched in the year 2018 and works well with existing code. It is an open-source mobile application development platform and using this will help one with the benefits like foundation libraries, widgets, and more. Flutter is fast and also helps one with the development of cross-platform applications.
