Cross- Platform Mobile Application

When choosing the development of your app, there isn’t one good option. It all depends
on what type of app you want to build, how much budget you have, and even when you
set a deadline for launching (among many other factors!). The multi-platform applications, for example, have a lower cost and faster development: with a single code, they can be used across multiple operating systems. However, this type of development also has its limits. In this article; we will talk about the features and development of cross-platform mobile application using one of the most extensive programming languages: HTML5.

What Is A Cross-Platform Application?

For those of you who are new to the app world, the difference between native and
cross-platform apps is this: The native applications are written in the language of each
operating system. This means that each system (Android, iOS…) will require different
development. The multi-platform applications have a unique code that is interpreted and
adapted to the operating systems.

We would say they are practically synonymous with the web applications that we have talked about a number of times. The development of cross-platform mobile applications can be done in two different ways: Use web development languages, such as HTML5, CSS, and JavaScript. This code is then presented in a native container, the WebView. The applications thus created are also known as hybrid applications. Use of native rendering tools. These serve as a bridge between the cross-platform code and native components. This type of development is done with frameworks such as Tamarind, React Native, or Flutter. One of the languages ​​that allow us to arrive at the development of multiplatform mobile applications. Let’s take a closer look at what it is.

What Exactly Is HTML5?

HTML5 is a markup language used to structure and display web content. It supports
advanced multimedia applications including audio and video. But it also allows us to
modify the layout of a page and therefore to modify its appearance. In this sense, how
can you use the html5 structure when you are a developer? How to build an app can
app developers benefit from this? The expert will be able to program in html5 interactive
applications that will be visible through the browser of any device.HTML5 code is precisely one of the most versatile languages for developing web applications and the
most used when building non-native applications.

Cross-Platform Programming In HTML5

First of all, we can point out that HTML5 is a very extensive programming language. In
fact, since October 2014, it has become the standard for web programming ll always
finds many resources in this regard. Additionally, the World Wide Web Consortium
(W3C) has affixed its “Recommended” seal to the fifth version of the language. New
from previous versions of HTML and other languages ​​is the native inclusion of video
and audio, as well as the automatic implementation of responsive design.

Importance Of HTML5 And Its Use In Cross-Platform Applications

We have already explained why the html5 programming language is important around
the world and for an Android or iOS developer. But do you know what are the
characteristics of this language which must become one of the best options for
programming cross-platform mobile application? Let’s outline the benefits of using HTML5
when building mobile apps. Its universality, that is, it works in all browsers, whether on
mobile devices or from the traditional computer.

The code is interpreted and displayed by any browser (Chrome, Safari, Firefox, and Internet Explorer). It is a clear audiovisual language that allows native audio and video to be included. He is betting on the display and integration of multimedia content in the creations. It is mobile and user-friendly. One of the advantages of programming applications with HTML5 is that this language seeks to be responsive, to adapt to the screen on which the content is displayed. This is why it becomes perfect for creating websites that will look like apps (i.e. web apps).

According to data from analytics firm Vision Mobile, more than 50% of mobile apps use HTML5 with JavaScript and CSS. Finally, the HTML5 language is open, that is to say, that
anyone can modify, improve, extend, or invent new services on applications already developed. For smaller budgets, it’s a good idea to research the cost of building an app first. Or even to start with a beta for your business or mobile game, starting with an HTML5 version to see if it works and if there is a market for it can be a big saving. Candy Crush type games (puzzles) can be started with this technology and then moved to the natives.

Advantages And Disadvantages Of Programming Cross-Platform Applications

Despite everything we told you in the previous section, HTML5 may not always be the
right choice for developing your application. We explain to you some advantages and
disadvantages so that you can decide according to different criteria.

Benefits Of Programming Cross-Platform Applications With HTML5

Why do many companies decide to go for cross-platform development over native
development? Here are a few reasons. Most used development language. HTML5 and
JavaScript is a programming language ​​that many web developers are familiar with. Web programmers can use their experience to get started in developing cross-platform applications very quickly and easily.

Fewer resources, fewer costs. You don’t need to double or triple the resources to build the same app on Android, iOS, and Windows Phone. This makes the final development less expensive. Consistency of the user interface (UI). The look and feel of the app will be consistent across the different devices where it is used. Faster launch. The application depends on a single development, so it is easier to adjust the delays.

Disadvantages Of Programming Cross-Platform Mobile Application With HTML5

If any of these questions seem critical to you, native development may be the best
option for your cross-platform mobile application.

  • Slowdown of the application.
  • Access to device hardware limited to available plugins.

The time investment to validate the operation on each platform. Even if you make sure the
the app will work automatically on any platform, that’s not entirely true. In practice, you should check the development on all platforms and make sure that it is good on one platform and that it works on others as well. Also, whenever an update is released for any of the operating systems, the application should be updated and it should be checked again to ensure that it will work correctly on no. any device. However, REMEMBER that even though the apps are cross-platform, an APK (Android Package) or IPA (iOS App Store Package) must be generated to be readable and displayed on mobile devices. This is why we will need the SDK (Software Development Kit) for each platform. You can also use a service that generates it automatically, such as Adobe Build.

Tools For Cross-Platform Development

The most used tools for programming in HTML5 to program cross-platform mobile
application, like WebView, are as follows:

Apache Cordova: is a framework for the development of mobile applications owned by
Adobe Systems that allows programmers to develop applications for mobile devices
using generic web tools such as JavaScript, HTML5, and CSS3, resulting in a hybrid
applications.

Angular: is an open-source JavaScript framework, maintained by Google, which is used
to create and maintain single page web applications.

Ionic: is a free and open-source tool for the development of hybrid applications based
on HTML5, CSS, and JS. It is built with Sass and optimized with Angular.

While the quality of these types of apps isn’t the best you can find in native development, it works great for small to medium-sized projects that don’t require very high performance or too much functionality. In fact, the first Facebook app was developed with this kind of technology until it was decided to program native apps.
