How to build an application using Xamarin.Forms

If Android and iOS applications are entertainment extravaganza in a newfound era, Xamarin is the director handling their performance from backstage. Simply put, Xamarin is an open-source platform meant to develop modern and dynamic applications for Android, iOS, macOS, and Windows with the .NET. Developed by Xamarin company which was later acquired by Microsoft in 2016, the platform features a community of over 1.4 million developers.

Developers make use of Xamarin.Forms to build Xamarin.Android, Xamarin.iOS, and applications for windows. Being an open-source UI framework, Xamarin.Forms help to create user interfaces in XAML with code-behind in C#. Moreover, it enables developers to accomplish end-to-end development goals. This means, building an application using Xamarin.Forms are great for companies to enhance user experience. As it is said to be a big cheese in the development field, this article explains the Xamarin pros and cons, process to develop an application using Xamarin.Forms, and some best Xamarin examples for references.

What is Xamarin

For beginners who are not cognizant of what Xamarin is, it is an open-source platform used to develop a cross-platform mobile applications using C#. The use of C# instead of HTML, JavaScript, and other programming languages makes Xamarin a unique yet robust platform for modern developers. Because of this, developers can work on three mobile platforms, that is, iOS, Android, and Windows. The best part about the platform is that it offers a wide range of tools that helps developers native-like mobile applications. In fact, they can have access to all the features of native SDK by writing one Xamarin C# code. The main uses of Xamarin are to share code, test, and business logic across platforms, and writing applications in C# using Visual Studio.

Features Of Xamarin

  • Xamarin supports native integration for smart iOS and Android devices such as Apple Watch and Android wear;
  • Cross-platform popular plugins such as battery status;

Xamarin Native vs Xamarin.Forms

Xamarin.iOS and Xamarin.Android are traditionally referred to as Xamarin.Native. These tools (Xamarin.iOS, Xamarin. Android. Xamarin.Mac) enables developers to implement native user experience while involved in cross-platform development. Xamarin.Forms is an open-source UI framework, based on Xamarin itself. It can be referred to as the advanced version of Xamarin.Native that helps developers build Xamarin cross-platform applications from a single shared codebase. Here are the top differences between Xamarin Native and Xamarin.Forms.

  • Development Time

Xamarin.Native is highly regarded in current times for the fact that it enables working with a single shared Xamarin C# code. The level of code sharing is 75% with Xamarin.Native. This cuts the overall development time and leads to faster cross-platform development. Xamarin.Forms, on the other hand, bring more time efficiency to the table as the code-sharing spikes to 95%. Moreover, in comparison to Xamarin.Native, it allows developers to create and share single UI code for all platforms, thus making the cross-platform development cycle fastest.

  • Development Cost

The right choice between Xamarin.Native and Xamarin.Forms can have a big impact on development costs. With Xamarin.Forms, companies only need to hire .NET platforms with no extra expertise. However, Xamarin.Native entails companies hiring developers who are experts in all the native platforms. The learning curve in the case of Xamarin.Native is also longer, thus adding extra cost in hiring and training developers.

  • Update And Maintenance

Updates and maintenance are a lot easier in the case of Xamarin.Forms as the framework shares code for multiple platforms. Besides, as the number of lines of code is reduced, there are lesser chances of bugs and errors in the application. The maintenance process is a little tricky with Xamarin.Native. Developers ought to care for the base code and platforms’ individual sets of code separately. There is no specific method to accomplish it all at once, thus adding more time and cost.

  • Functionalities And User-Experience

Here Xamarin.Native is a clear winner against Xamarin.Forms. This is because it provides access to various plugins, controls, and APIs for both Android and iOS. It is a great choice if developers need an app to access the device’s native features. As Xamarin.Forms is a single code base framework, the extra functionalities may not be possible in this case. This clearly means the Xamarin platform is a great way to enjoy different functionalities for different platforms.

Why Should Choose Xamarin Build Cross-Platform Apps

Mobile applications are key for most businesses to present a user-friendly experience. This especially holds true for online businesses that aim to increase the number of users for their success. That’s where the concept of ‘cross-platform development’ enters into the scene. This means creating compatible applications that support multiple platforms such as Android, iOS, and Windows. Though there are many platforms with advanced features, Xamarin is widely accepted to build hybrid applications for business success. So far, there are over 15,000 companies that rely on this framework for cross-platform development.

Below listed are the major grounds for developers and businesses who wonder – is Xamarin good for developing cross-platform applications.

  • Simple and Convenient

Developers find it easy to build cross-platform applications on Xamarin in comparison to other platforms. One of the main reasons is the use of C# and .NET framework which comparatively comprise a low learning curve. Besides, the use of a single language, that is Xamarin C# leads to easy updates and maintenance. Adding more, the platform also supports integration to the SDK. This helps in the easy addition of the features and streamlining auto-updates. Overall, Xamarin provides a reliable environment to developers and businesses for developing cross-platform applications.

  • Native Like Experience

Native applications help businesses to provide a great user experience. Xamarin is a key platform that enables developers to build robust native apps with its APIs and toolkits for Android, iOS, and Windows. Moreover, the platform-specific elements and technologies available in C# and Visual Studio makes it possible for developers to customize applications according to individual requirements.

  • Performance

Xamarin cross platform performance is close to native. This is because the development of Xamarin is mainly focused on sharing business logic rather than codebase. Even Xamarin.Forms enable broad code sharing with less platform-specific applications. The platform also allows easy testing of applications using fragmentation, CI, object-based UI testing.

  • Flexibility

As Xamarin is an open-source platform, it allows users to choose components according to the requirements. It provides extensive resources to developers to fulfill their goals of development. These cover cross-platform libraries, UI controls, and third-party web services.

  • Security

Security is an essential requirement for businesses when looking for a platform to develop applications. Xamarin cross-platform apps are secure as the connections between different apps are encrypted and hosted by Azure Cloud. The best thing is that the connection and backend Azure features HTTP certificates and 24 hours protection against malware.

Pros and Cons of Xamarin for Cross-Platform Development
