Hybrid mobile applications are like any other applications you will see on your mobile. They get easily installed on your mobile device. You can look for these apps in the App stores. By using these apps, you can engage your friends via social media, play games, track your health, take photos and much more.
Hybrid mobile applications are developed using a combination of web technologies like CSS, HTML, and JS as same as websites on the internet. The major difference is that hybrid applications are hosted inside a native app which further uses a mobile platform’s WebView. Here, WebView is a chromeless browser window which is typically configured to run fullscreen.
In fact, hybrid mobile apps enable you to access various device capabilities viz. camera, accelerometer, contacts, and much more. However, inside mobile browsers don’t allow you to access these capabilities from it. Furthermore, hybrid mobile applications include native UI elements in those situations where it is necessarily required, as proved by Basecamp’s approach towards hybrid mobile application development.
It is not easy to answer the question how a mobile app is built. Similarly, hybrid mobile apps are no different. A well-written hybrid application should not behave or look any different than its native equivalent. However, users don’t care about it as they only want an app that works well. It is what actually matters to them. If you are trying to figure out whether a mobile application is hybrid or native, it would be like you are trying to differentiate rare grape varieties of wine.
Unless you are the one who really cares about this, it is not terribly important. What all matters are how your hybrid mobile application development is going to work in the long run as no one will care about how it was built. A hybrid mobile application is said to be good if it performs well for its users.
How are hybrid mobile applications built?
Like other websites are built, hybrid mobile apps follow the same manner. Both are built with a combination of technologies like CSS, HTML, and JS. Generally, a hybrid app targets a Web View which is hosted inside a native container rather than targeting a mobile browser. This allows its users to access various hardware capabilities of the mobile device.
If we talk about Apache Cordova, it was actually started as a project named PhoneGap. But nowadays, PhoneGap is considered as a distribution of Apache Cordova which includes additional tools. To know more about its history, you can check out Cordova, PhoneGap and what’s in a name?
Various application assets like CSS, HTML, JS are packaged via tooling through Apache Cordova for targeting platform SDKs. Once a hybrid app is built, it can be run just like any other app on the mobile device. Apache Cordova provides the tooling that is highly driven by a command line interface. However, mobile app developers can still leverage IDEs such as Visual Studio and effective solutions like the Telerik Platform to further increase productivity.
Since mobile app developers don’t want to be getting locked into proprietary platforms, so hybrid mobile apps give a way to mobile app developers for re-using their existing skills in web development. This mainly includes SDKs provided by platform vendors and the programming languages.
Obviously, it’s true that mobile app developers become able to target multiple platforms with hybrid mobile app development. But when it comes to WebView or web runtime, each platform comes with a set of caveats. This is more true for Android and not consistent between OS versions.
Furthermore, there must be some unique capabilities of platforms to which a mobile app developer may wish to target. In such cases, a combination of platform-specific code and plugins must be utilized which will take advantages of those capabilities. Optionally, mobile app developers can take advantage of 3rd party web runtimes such as Crosswalk which can be further embedded into your hybrid applications.
When should you build a hybrid mobile application?
It is the foremost concern of every mobile app developer who wants to build a hybrid mobile app. The first thing you should do is to check your mobile application’s requirements. Before committing to a platform strategy must evaluate the technical merits as well as non-technical merits of hybrid mobile apps over the web and native mobile apps. You should first consider the following questions before developing a hybrid app:
– What are the technical abilities of your mobile development team?
– Which mobile app platforms do you wish to target?
– Are you looking to use the multiple capabilities of the mobile device?
– Do you want to distribute your apps through the app stores?
– Does the hybrid approach really live up to its promise in the coming years?
The above questions are needed to be answered properly before the development of mobile apps. You may further evaluate more questions in detail.
WHICH MOBILE APP PLATFORMS DO YOU WISH TO TARGET?
You may have a number of choices if you want to target more than one platform. This is because the web offers a highly interactive solution for this purpose. However, the mobile browser is your target. HYbrid apps lend itself to this due to its reliance upon the WebView.
On the other hand, Native apps find a unique space among this. In fact, you are essentially coupled to this platform if you rely upon platform-specific programming languages and vendor SDKs. For this case, Objective-C or Swift is used for iOS, Java is used for Android and C# is used for Windows phone.
DO YOU WANT TO DISTRIBUTE YOUR MOBILE APP VIA APP STORES?
If you want to distribute your app via an app store, you must build a native or hybrid app. You can not distribute sites through app stores. Hence, browser’s address bar is provided for this. Despite this limitation, whether you build a hybrid or native app, it is strongly recommended that you must have a website available for your mobile app. You need to create this because this will be the first place your app users might expect to go in case if they stuck with any problem.
ARE YOU LOOKING TO USE THE CAPABILITIES OF THE MOBILE DEVICE?
As compared to native and hybrid apps, websites have a limited set of abilities. These limitations are put up by a browser that effectively sandboxing it from mobile OS. A lot more device capabilities are exposed through HTML5 with the help recent developments with mobile browsers which include geolocation, camera, and others.
In spite of these advancements, support for advanced functionality is still limited. For an instance, streaming and media capture are still unsupported in various mobile browsers. Due to these limitations with mobile browsers, there are many mobile app developers who are compelled to evaluate native and hybrid apps as alternatives. These platforms enable mobile app developers to access device APIs. While in case of hybrid apps, plugins support this capability.
It is often said that native app development is best suited for apps where graphics performance is paramount. The best example is the mobile games which completely rely on complex visual interactions on the screen. No matter, how wonderful game app you have developed for your users and how flawlessly it operates from a functional perspective, you can expect this game app to have a very low app store rating if it is lacking energy. Due to these reasons, mobile app developers have long argued for using a hybrid approach to build their game applications.
However, there exist a number of solutions for hybrid mobile apps. This includes WebGL and HTML5 Canvas that are well-suited to build game applications. In fact, these technologies are most preferred and approachable for mobile app developers due to the presence of libraries like EaselJS, Paper.js, and others. This is not limited to game development only. Developers build more traditional, line-of-business apps by using frameworks like Kendo UI and Famo.us.
