A Tutorial On Xamarin

Posted on May 15, 2018 by Super Admin Testreveal

The Emergence of cross platform ecosystem in mobile app development

Until recently, mobile app development specialists had to follow a stringent slot of either iOS, Android or Windows. Due to differing ecosystem, language constraints and style, the process of software development on each platform was entirely different. It was therefore extremely challenging for developers to build separate mobile apps for these platforms.

However, Xamarin came to transform the process and altered the course of the situation through enabling unique facility known as cross platform development. Xamarin allows developers to build application for iOS and Android with C# and .NET libraries. To establish the performance and feel of native apps, Xamarin mobile development enables developers to leverage full range of native APIs and UI controls available from the OS and hardware of the respective devices.

What is Xamarin?

Xamarin offers unique ability to iOS and Android developers to work their way towards writing mobile applications in C# and then run them on any desired mobile platform or OS.

Earlier, native languages like Objective-C, Swift and Java were the only limited choices for creating iOS and Android applications. In a past few years, Xamarin has bred novel ecosystem of platforms for cross platform mobile application development. It offers single language (C#) and runtime that seamlessly functions across iOS, Android and Windows and compiles native apps.

Why to choose Xamarin?

Each platform has its own discipline of features and methods of writing native applications where native code interoperates and interacts smoothly with underlying Java base. Some platforms support apps written in HTML and JavaScript whereas some allow C/C++ code. In such traditional setting, there should be separate codebases for each device or your app run via web browser, which imposes major concerns of maintenance and cost.

In Xamarin mobile development, developers eliminate typical issues as faced in native app development. For instance, web browser apps do not run natively as its UI is not familiar to device ecosystem and its performance is also compromised due to the absence of native code.

Xamarin’s cross platform capability is superior because:

It consists of native features: UI, API access and performance
Native UI of each device makes your app user-friendly
You can perform the same coding results as achieved using Objective-C, Java and Swift
Due to access to device’s individual APIs, you can experience native performance
Enjoy shared codebase across all devices
Cross platform apps offer same-day support for each new OS releases

Xamarin products

Xamarin offers:

iOS
Xamarin Android
forms

Specialities of Xamarin.iOS and Xamarin.Android

Developers can leverage the power of UI toolkits Xamarin.iOS and Xamarin.Android in order to create an app using each platform’s APIs .NET framework. While developing apps with these two products, you can relish customizations for UI for each platform.

In both UI toolkits, you will have the benefit of separate UI approach. Xamarin.iOS and Xamarin.Android comes with shared code base in C# which is shared across platforms with separate UI for each.

Xamarin mobile development with Xamarin.iOS and Xamarin.Android seems suitable for:

Apps where native-like behaviour and interactions are expected
Development of apps with platform-specific native APIs
Mobile apps with UI customization scope

Specialities of Xamarin.forms

The best part about using Xamarin.forms is that while building an app with this UI kit, developers will need to write code only once. At the moment of runtime, this written code is translated to platform’s native environment.

Another speciality of Xamarin.forms is that you can enjoy the benefit of the maximum code sharing which is as much as 90% with this UI kit.

Hence, Xamarin.Forms is suitable when:

You don’t require platform-specific functionality for apps
Code sharing is more crucial than custom UI

Xamarin components

With the launch of Xamarin 2.0 in March 2013, the Component Store was introduced to help developers save time and accelerate Xamarin application development process and enjoy potential features. The store contains the stunning catalog of UI controls, charts, themes, cloud services and other great features that you can integrate in your app in matter of a few clicks.

To speed up the process of adding Xamarin components to your app, the Store is integrated into both Xamarin Studio and Visual Studio. To get detailed insight into how exactly you can create, bundle, test and submit your components to the Xamarin Store, refer to the full Xamarin Component Store Guide.

Here is the quick overview to Xamarin components and submission.

Submission Overview

After component creation and packaging and testing, you will need to submit your components and Xamarin plugins to Xamarin component store. Before you proceed, it is believed that you have some experience with yaml and building a component. If you are not aware of how to produce a component, start going through its insightful Xamarin Component Store guide.

Once you have finished building a component and are happy with it, you can submit your creation to Xamarin Store where it will be reviewed and approved.

You will need to set up your own Xamarin Account in case you don’t have one. To proceed for creating the Xamarin account, visit Xamarin Home page and click “Sign In” at the top right corner. Follow the instructions there after clicking on “Create a new account”.

If you are not willing to keep it open source, you can place the specific charge for the use of any of Xamarin components submit by you on the Store. To officially set up the charge for each component and Xamarin plug-ins you create, you will need to provide your account details. The sales will be credited to your account provided that 30% of the revenue is deducted as commission towards Xamarin Store.

To understand the process of updating the existing component – which is different from creating a new one – you should study the guide on Xamarin store website.

Approval Process

After you have submitted the new or updated component, you wait for Xamarin Store to review it on the basis of Component Review Guidelines. If they discover any issues or errors, you will be contacted with the details of needed fixes and improvements.

If there is not issue found in your component or Xamarin plug-ins, it will receive the final approval and be made available officially on the component store where people can explore and download when required.

How Xamarin Benefits Cross-platform App Development

As Microsoft resolutely states, “Apps built using Xamarin look and feel native, because they are native indeed!” Let’s start with this one as we go to describe all the incredible benefits delivered by Xamarin for cross-platform app development.

All things Native

With Xamarin application development, you are confident that any app built using this platform will reflect native-like qualities, such as:

1) Native UI: Xamarin cross-platform IDE is built with high priority shown to app performance and UI quality. Hence, Xamarin-built apps have native UI controls and look and behaviour that end users truly expect.

2) Native API Access: Since Xamarin application development provides access to device-specific functionalities and platform-specific capabilities (ARKit and Android Multi-Window mode), developers can foster unique ability to emulate native app technologies used universally.

3) Native Performance: Apps built using Xamarin technology is enriched with platform-specific speed and are designed to generate organic native performance. This is because during runtime UI components are converted into device-specific elements, avoiding the code interpretation, eventually producing native experience.

4) Fast pace of development cycle : One of the main attractions of Xamarin for cross-platform app development is that its code can be reused and recycled. As up to 90% portion of code can be reused across different platforms, developers find it easy to economize on both time and vigour which they can invest later in other innovations. Thus the simplified code sharing significantly impacts the pace of development cycle.

5) Extract great value from C#: Having spent much of time in mobile application development, developers might be familiar enough to use programming languages from the C family. C# which is a much sophisticated, general-purpose language that offers type-friendly comfort for Windows platform. It has object-oriented coding and contains all the improvements and advancements of C++.

6) Shared app code: With Xamarin cross-platform app development, it is possible for developers to share app code across multiple mobile platforms and OS. Xamarin has unique edge since its major UI logics such as input validation, database interactions, web service calls, back-end API integrations are written in one language only which is C#. So you can use the same APIs for 75+% of app code across all mobile development platforms.

7) Outstanding flexibility: Xamarin gifts you outstanding flexibility when it comes to using the same APIs and UI controls as used for development of Android, iOS and Mac applications. You can develop apps easily across these platforms without changing much since Xamarin supports platform-specific programming languages viz Java, Objective-C, and Swift. Due to this allowance, users can have new features installed as soon as they are launched for the respective device.

8) Agility and economy: This particular benefit appeals to both enterprise-grade businesses and developers equally. The reason why Xamarin cross-platform mobile application development contributes to business growth is its Rapid Mobile App Development (RMAD) capability. All credit goes to Xamarin UI form libraries that enable simplified, swift and frictionless development. It provides developers with an added advantage of agility they need to expedite the process, and businesses, too, benefit from Xamarin’s low-cost development model.

9) Great hardware compatibility: Since Xamarin cross-platform development gives you full access to its powerful components and APIs, your app will conduct native interactions with the device OS. This ultimately lowers any compatibility issues you face earlier in the app development. Xamarin gives developers an opportunity to capitalize on and connect with applications’ common device functionalities for various platforms on a larger scale.

10) Enhanced accuracy: Xamarin contains quintessential type-safety feature which is beneficial to developers who want to spend minimum time correcting the errors they face while writing the applications. This rich feature in Xamarin application development allows you to avoid possible type-specific syntax errors and inaccuracies. Developers can simply avoid the involvement of boilerplate or verbose type annotations, thus augmenting convenience and speed, and eliminating occurrences of flaws.

11) Incredible customization: It is advantageous for any mobile app developers to be able to tweak and add custom feature to applications. Xamarin cross-platform app development tool enables facility for you to use and work on native libraries so that you can create applications with incredible customization.

From above discussion, it is crystal-clear that Xamarin is super-beneficial to both developers and businesses bodies. Not only Xamarin mobile applications offer competitive advantage to enterprise structures, but it also equip developers who wish to work on intuitive, sophisticated and time-tested cross-platform development tools.

Summary

Xamarin mobile application development is a considerable cross-platform solution that offers simplified coding and native user experience across multiple device platforms. The robust cross-platform tool helps developers build a single app, reuse code for common business logic and optimize the speed of app development cycle.

Due to rapid app development capability, hardware compatibility and API flexibility, Xamarin is a platform of choice for modern developers who seek real-time value while building, testing and deploying apps with just one tool. Finally, we can firmly say that a wide community of talented Xamarin professionals and the use of advanced C# definitely make Xamarin a comprehensive application development platform for both business enterprises and developers.

React Native vs Xamarin – Which is Better?

Posted on April 6, 2018 by Super Admin Testreveal

As thousands of applications are launched on Google Play store and Apple app store, the demand for business-specific mobile application development is booming huge. Whether it is for iOS or Android platform, the ultimate success of your mobile app depends on the cross-platform technology in use and the development standards to be maintained.

Though Java, Objective-C and Swift were used to write applications in past, the new cross-platform development tools that are making enormous buzz are React Native and Xamarin.

Recently, the question of react native vs xamarin performance has come to interest people active in mobile app development arena. These frameworks not only stimulated the era of highly engaging and performance-oriented mobile apps, but they also transforms coding phenomenon, simplifies development cycle and emerges cost effective for modern businesses.

So who is superior to the other? In the below section of xamarin vs native, we are embarking on finding the answer and will discuss how to make an informed decision.

Xamarin at a Glance

Xamarin was launched in May 2011 and was acquired later by Microsoft. Xamarin was intended for addressing the prevalent issue of disconnected technology to facilitate the native app development using its open source platform.

The framework uses C# language that functions seamlessly across multitude of platforms (Android, iOS, and Windows). Due to its ability to write native UI codebase for mobile app development, more than 1.4 million developers were using Xamarin in the first quarter of the year 2017.

Used by many popular brands, this cross platform app development framework offers competitiveness in building exceptional native app interfaces that effectively surpasses the limitations of hybrid apps.

React Native at a Glance

Introduced by Facebook in 2015, React Native stands out as a cross platform app development technology due to the fact that it uses JavaScript to develop a native mobile app.

The annual survey by Stack Overflow confirms that JavaScript is one of the most illustrious technologies mainly because it involves steel learning curve for developers.

Xamarin vs React Native 2018: Which One Feels Better and When?

When it comes to making a candid, unbiased comparison between React Native and Xamarin cross-platform native app development frameworks, both seems to surpass each other in many situations. Here is what you need to know about their working standard before you can pick the one.

1) Cross-Platform Development Environment

While discussing xamarin vs native, one can easily discover how Xamarin cross platform provides immense flexibility in terms of development environment.

Once can build and compile a code for different platforms with Xamarin unlike React Native that does not offer similar support unless via Expo. However, Expo may not be as powerful since it also has limited support capability.

2) Code Deployment

Xamarin developers will need to opt for compilation to generate an executable file to be tested later on emulator or a device. This process takes good amount of time depending on how complex the project is.

React Native on the other hand enables you to save the code and see results instantly using “hot module replacement”.

3) The Question of Choices

Being a JavaScript expert, you will find it easy to get started with building native apps with React Native.

On the other hand, if you are conversant with Microsoft-owned C# expertise, then Xamarin would be the most appropriate choice as you can build iOS and Android apps using C#.

4) Accessibility and Availability

React Native is fully open source framework, so you can use it for building applications for tablet, iOS and Android.

However, when thinking about Xamarin, you need to spend some amount since its free version offers limited resources and features especially for enterprise-grade app development.

5) React native vs Xamarin Performance

As far as React Native vs Xamarin performance goes, significant factors like GUI, 64-bit support and fast code execution matter most.

Xamarin emerges more beneficial for the fact that it allows developers to run the code fastest on both iOS and Android platforms.

It provides full range of support for 64-bit mode and enables rapid UI development because of direct access to native tools.

This factor is not much favourable for React Native as it does not support 64-bit mode on Android completely. Additionally, it gets worse for iOS where it appears to run code at dissatisfying speed.

6) Advanced Capabilities For Development

Xamarin vs React Native must include this critical factor that focuses on which among Xamarin and native offers advanced development capabilities.

Usually, this one goes in favour of React Native as it is JavaScript based and offers more features, making the process more convenient for mobile app developers.

Xamarin, on the other hand, enjoys the reputation of being a legacy or classic tool that does not contain as many snazzy or evolved features in Android studio as carried by JavaScript framework.

Some of them might be automatic restarting, cold swapping code, instant updates, etc.

7) Testing Capabilities

Though you can perform UI testing on both platforms, it is easier for Xamarin developers to do unit testing in Xunit and debug in Xcode Simulator for iOS.

However, with React Native you are compelled to debug in the Android Emulator where issues are likely to occur.

8) Brand Users

React Native has brand users such as Facebook, Instagram, Airbnb, Walmart, Skype whereas Xamarin is used by big names such as Slack, Siemens, Honeywell.

Who Wins the Battle?

Even after exploring all the pros and cons of React Native and Xamarin, it is not easy to conclude that one s better than the other. Developers can decide it based on how accustomed they are with a specific framework.

The Xamarin vs React Native battle is subject to certain aspects of development, maintenance, code sharing and testing, and developer’s personal experience and preferences.

But developers who is familiar with .NET and C# may choose xamarin cross-platform app development. It is after all a matter of opinion as the entire community of developers are split between both frameworks.

Hence, the ultimate choice comes down to what framework a developer is quite comfortable with. No matter what you decide, the native-like look and feel, performance, quality and usability of the end product must come into focus when telling which one wins the battle for you.

On clicking Ok, one gets to see a number of individual projects such as WeatherApp (Portable), WeatherApp.Droid, WeatherApp.iOS, etc.
Add Newtonsoft.Json and NuGet package to the PCL project that can be used to process information obtained from weather data service
Once Newtonsoft.Json is installed successfully, one must find and install Microsoft.Net.Http package
Once the above steps are complete successfully, the system is ready to build a new solution.
On successful completion, one must ensure to confirm that there are no build errors in the development

3. Share the data service code on different platforms

The best aspect of developing any app using Xamarin is that the code is written in portable library class (PCL), which makes it easier to be shared on different platforms. In case of an Android, iOS and Windows apps, PCLs are automatically included in the package.

4. Design the look and feel of the app

Design of an app plays an important role in its success or failure. Therefore, one must be extra careful when designing these apps. To design the look and feel of the app, one needs to follow a few simple steps as mentioned below:

Go to the solution explorer, expand the WeatherApp.Droid>Resources>layout folder to open Main.axml and the file in the visual designer
Delete the default button present in the designer
Open the toolbox to drag a RelativeLayout control on the designer. This control will be used as a parent container for all other controls
Go to the Properties window to set the background property. This should be followed by the pulling of Text View control onto the Relative Layout control that can, the, be used to set various properties such as zipcode, number, etc.
Finally go to the properties window and sort the list as per one’s own choice

5. Replace shared code

Once the solution is ready, one can open its file in the code editor so as to replace the automatically geneayed UI code

6. Run the app

The app is now ready to use. One can opt to make it a start-up project in explorer or use it on the most suitable device.

7. Test the app

Checking an app developed for Android is easy as one needs to use Visual Studio Android Emulator. All one needs to do is select the app project, choose a device to copy and then click to start. The app is perfect to be used by all if it runs perfectly on Android device.

Testing an app for iOS is a bit different as it requires an iOS Mac to copy the content. One needs to set up and connect to Visual Studio followed by selecting the app project, switching the design plan to iPhone Simulator and then finally, choosing the version of device used and click Play. X`

On successful completion of the above mentioned steps, one gets ready with an app that has been developed on Xamarin. Since the platform is rich in its properties such as code sharing, efficiency and use of single technology stacks, the platform is getting preference among the developers. The apps developed for each platform are different and unque, including visual studio mobile app development. Therefore, it is better to use Xamarin Cross-Platform Development rather than taking a new sort of risk.

Xamarin Vs Native App development: Which is the Better Choice?

Posted on October 24, 2017 by Super Admin Testreveal

Working with Xamarin and client target platform evokes mixed reactions. Both of them have their own pros and cons. The former is compiled into the native code and uses the common interface. Mobile App Development Company uses either of them; however, as mentioned above, there are some trade-offs that we’ll analyze here in detail.

Advantages over the native platform:

Sharing of code:

Using Xamarin, you can share the code between the iOS and Android platforms. Various attributes such as networking logic, parsing and navigation logic can be easily reused across the different apps on the platform. They help the developers to streamline the coding process and to identify the bugs easily. In fact, the consistency of the code makes the platform more efficient for the developers. All they have to do is to make corrections at a single place and to let the changes propagate through the app.

Usage of C#:

One of the most important advantages of the Xamarin platform is that it allows coding in C# language in all the applications. It is quite capable when compared to objective-C because of the type safety attribute. Some other capabilities include implicit typing, extension methods and other closure that make C# an amazing tool for development. Due to inbuilt error handling mechanism, the codes are clean clear and reliable. They are scalable as well as fully capable of handling large amount of data.

Net and C# libraries:

Using C# language provides complete freedom to the developers as they can use window libraries right from the old ones to relicensed versions. Xamarin Cross-Platform Development plays an important role in enhancing the capabilities of the applications. In fact, PCLS support is also available in C# language.

Disadvantages of Xamarin:

Compatibility issues:

Xamarin supports new APIs; however, in recent versions, it is incompatible with TV OS2 and “watch OS” in stable channels and cannot bind to Swift only libraries. In short, it is not possible to use the advanced features using the Xamarin platform.

Third party support:

iOS and Android provide third party applications that can be seamlessly used; however, they are not able to work with Xamarin interface. The workaround is way too complex as developers have to write the binding code from the scratch.

Platform specific .net libraries:

If you are using Xamarin, it is not possible to utilize PCL core library. In addition, the .NET library doesn’t offer a required interface to the developers. As a result, the capabilities of the applications on the platform get hampered. Even highly popular Google APIs face lots of issues when used with Xamarin; therefore, it is better to use the native platform in such cases.

Conclusion:

You should use Xamarin only when the app is equipped with lots of complex front end logic. Since coding is minimal, you do not have to spend a huge amount of money to create the application. If your team is highly experienced in C#, usage of latest offerings of Xamarin Development Company would go a long way in making the app efficient and robust. Even it can be used to support multiple windows devices without any technical glitches.
