Create captivating mobile experiences in 2024! Browse the roadmap to hire the best mobile app developers, ensuring usability, innovation, and engagement.
In the first quarter of 2021, 54.8% of all internet traffic comes from mobile devices . Think about it for a second. The majority of all internet traffic does not originate from a desktop or laptop, but from a smartphone. This is a percentage that your company cannot ignore. In fact, if you ignore this number, you are missing out on more than half of the world's internet traffic.
Can you pay for it?
Chances are very good that the answer will be a resounding “No.” If you don't see the value in such a proposition, your business will suffer for years to come. Why? Because there are many countries around the world where the only affordable option is cheap Android devices. These countries consist of millions and millions of users.
But it’s not just financially challenged populations that rely on mobile devices. Given how busy the modern era has become, fewer and fewer people have time to sit at a desk and use a standard PC or laptop. People need mobility, so they rely heavily on their mobile devices.
The same should happen with your business.
Given that the mobile domain will only continue to increase in the coming years, your company needs to focus heavily on mobile app development, both on the Android and iOS side. What does that mean?
You need to hire mobile app developers .
What does it mean to be a mobile app developer?
In the past, a developer could learn a programming language, get really good at it, and it would be perfectly suited to their business model. They would bring their skills to the company, where they would be integrated into a team to work productively on delivering a product.
Modern development is not that simple. The mobile application developer needs to have some more skills to be productive in his business. They need to be able to design a quality UI, use one of the platform-specific programming languages and frameworks, create an easy-to-use single-page application, be able to connect the application to a database, and know how to deploy the app on a company's website or on the Google Play Store and Apple App Store.
And this workflow doesn't include the usual testing and debugging required to build reliable applications.
So yes, the process of building a mobile app can be complicated. But the end results will be worth it. In short, you need to find a mobile app developer to hire .
Depending on the platform you are developing for, you will need to know specific languages and how to use certain frameworks. Let's take a look at this by operating system. This is a requirement when you hire a mobile app developer .
Android development
To develop for Android you must know Java. This is absolutely necessary because it is the official programming language of the operating system. You will also have to know XML, as this is how developers lay the foundation for defining the user interface in Android applications.
The next one is the Android SDK (Software Development Kit), which consists of Java modules that give developers access to all the functions of the mobile device, such as the camera, microphone and accelerometer.
Android developers should also be able to work with Android Studio, which is the official IDE (Integrated Development Environment) for Android. Android Studio is a complete IDE, so it includes all the tools that developers are accustomed to using.
Every Android development company must also be familiar with the various APIs required to interact with the services required for the device to function and interact with other services.
Android developers must also be able to work with third-party databases (if the data is stored outside of the device's local storage) or with SQLite (if the data is stored locally).
Finally, Android developers must have a solid understanding of Material Design (and Material You, for Android 12) so they can create modern-looking apps that take advantage of the Android interface.
iOS Development
To develop for Apple's mobile platform, your developers will need to learn Swift and also be familiar with Objective-C. These developers will also need to install and be able to use Xcode, which is the Swift IDE. However, to install and use Xcode, you must have an Apple laptop or desktop computer.
As far as APIs go, you should familiarize yourself with the Foundation, UIKit, CocoaTouch, and iOS graphics APIs. Other skills include UI and UX design, Apple Human Interface Guidelines, 2D and 3D graphics frameworks like SpriteKit and SceneKit, and OpenGL or Metal.
Mobile App Interview Questions
Why would you use the React Native framework to develop mobile apps?

What is the difference between a native and a hybrid app?
A native app is one created to be installed on the mobile device, while a hybrid app is one that installs a native container on a device that displays content pulled from a website.
What is Xamarin?
Xamarin is a cross-platform development technology from Microsoft that makes it possible to build native mobile applications that use the same code base, whether they target Android or iOS.
What is a progressive web app?
A progressive web app is an app that has the look and feel of a native mobile app.
What are the four application components?
- Activities – An entry point for user interaction, represented by a single screen with a user interface.
- Services – A component that runs in the background to keep an application running or extract data from a remote service to a locally installed application.
- Broadcast Receivers – A component that enables the delivery of events beyond the scope of the user's regular stream.
- Content Providers – Manages application-specific data that can be stored on the local file system.
How does Xamarin share code across platforms?
Xamarin uses the following three tools to share code:
- .NET Standard Libraries
- Shared Projects
- Portable class libraries (deprecated)
