Why is it good to hire Xamarin developers and designers in Ukraine?
Web app development has now become increasingly portable, and a lot of tasks that required the use of computers a few years ago can now be done with a few taps and swipes on smartphones running mobile applications. With over 2.4 billion smartphone users worldwide, it is not surprising that the use of mobile applications has become extremely widespread, and as of 2017, there are a whopping 197 billion monthly mobile app downloads across the globe.
The global penetration of mobile applications has led to a flourishing mobile app market, just as the rise of the Internet has given birth to the web development industry. One of the major challenges faced by mobile app developers, however, is the rise of different mobile platforms, each using its own programming language. This required a separate development effort for each operating system, so an application that’s meant to run on iOS, Android and Windows needed to be developed three times.
Xamarin aims to abolish the walls dividing these operating systems by allowing cross-platform application development with just one piece of code. In this article, we take a close look at Xamarin mobile application development.
Xamarin: An Overview
Xamarin is a tech company established in May 2011 with the goal of allowing the development of iOS and Android applications using the C# programming language, which is the native language used for development of Windows applications. In December 2012, the ability of Xamarin tools was further extended to support the development of MacOS applications.
In February 2016, Microsoft acquired Xamarin and has since been integrated into Visual Studio, Microsoft’s IDE for application development. To date, the cross-platform Xamarin programming tools for Android and iOS, which are individually called Xamarin.Android and Xamarin.iOS, have been grouped into what is called Xamarin Platform, and it goes alongside other Xamarin products such as Xamarin Test Cloud for multi-device application testing and Xamarin Insights for real-time app monitoring.
Xamarin is currently in use by over 1.4 million developers from over 120 countries. According to the 2017 Stack Overflow Developer Survey, 8.3% of all developers worldwide use Xamarin. Some of the most well-known companies that use Xamarin in their applications are Sennheiser, JetBlue, Pinterest, Fox Sports, and Thermo Fisher Scientific. Xamarin has also been used to create many cross-platform mobile games, such as Draw a Stickman, Wordament, and Skulls of the Shogun.
Xamarin UI Features
By default, the Xamarin Platform enables developers to create the business logic of mobile applications using a single codebase while still using native UI components that are platform-dependent. With this route, developers can achieve up to 75% code reusability.
However, the Xamarin Platform also offers developers its Xamarin.Forms framework, which allows a Xamarin designer to create user interfaces using a single C# code. These user interfaces are then mapped to each operating system’s native UI components. While this option gives a Xamarin forms developer less flexibility in terms of personalizing the application for different platforms, it allows them to achieve up to 100% code reusability. Some of the features of the Xamarin.Forms UI design are:
- Pages – Several different pages that are standard to mobile applications are available out-of-the-box, such as content pages, master detail pages, navigation pages, tabbed pages, and carousel pages.
- Layouts – Different layout types are also readily available, among them stack layouts, absolute layouts, relative layouts, and grid layouts.
- Controls – There are many available controls for Xamarin.Forms UI, including date pickers, time pickers, progress bars, search bars, maps, and sliders.
- Animations – Xamarin.Forms also allows for basic animations such as rotation, fading, and scaling, and these may be combined to achieve more complex animations.
One additional service offered by Xamarin is the Xamarin University, an online platform for developers to receive official training for the Xamarin Platform technologies from accredited experts. In addition to training, Xamarin University also offers Xamarin certification, which awards developers who have shown mastery of Xamarin application development with an official certificate. This can be a good credential for Xamarin certified mobile developers to inform their employers that their skill level passes the standards set by the Xamarin company.
There are two tiers of Xamarin certification: Xamarin Mobile Professional Certification, and Xamarin Mobile Developer Certification. In order to be granted certification, a developer must take all necessary training and pass the certification exams corresponding to the specific certification tier they wish to acquire. For the Professional Certification, the developer must have taken all introductory training on various aspects of Xamarin development and pass the Professional Certification exam. For the Developer Certification, the developer must have taken all training, including introductory and advanced ones, as well as pass both the Professional Certification and Developer Certification exams.
The amount of requirements needed to acquire certification ensures that only those developers who meet the high standards set by Xamarin are granted the Xamarin Certified Developer title.
Here are the usual types of projects that Xamarin developers are typically involved in.
Full App Creation
All Xamarin developers must be up for the challenge of developing a complete cross-platform application from the ground up. Typically, this involves clients who already have the general idea of the application they want to create, and the developer is tasked to bring their ideas into fully-working mobile applications.
- Tutorial app for Android and iOS
- Cross-platform dating application that runs on mobile and desktops/laptops
UI Design and Creation
One of Xamarin’s key features is Xamarin.Forms, its unique user interface creator that is then mapped to the native UI implementation of whatever device the application will run on. A Xamarin UI designer may therefore be asked to come up with and implement a great UI design that will suit different operating systems.
Bug Fixing and App Modification
Some clients already have existing applications written using Xamarin, but want to modify current functionalities, add new features, or fix some bugs. Developers must be prepared to read Xamarin codes written by other developers.
- UI improvement and additional functionalities for current mobile app
- Change UI layout and fix some bugs of Xamarin app
Some applications are written in a native mobile language, and clients want them converted into Xamarin. Other want the opposite: they have Xamarin applications they want to have converted into a native mobile language.
