Hybrid App Platform

If you are preparing for a Hybrid App Platform interview, Must go through these questions series.Here you will find latest interview Questions and answers on Hybrid App Platform Frameworks and tools.

Hybrid App Interview Questions.

A hybrid app is an application that merges elements of both native apps and web applications and is a web app that has been put in a native app shell. And also, once they are installed from an app store, the shell can attach to whatever capabilities the mobile platform provides through a browser that's secured in the app. The browser and its plug-ins operate on the back-end are invisible to the end-user. Moreover, hybrid apps are accepted because they allow creators to write code for a mobile app and still contain multiple platforms and since hybrid apps add a layer between the source code and target platform, they may perform slower than native web versions of the same app.

  • It incurs lowest cost wit the easiest way for the development
  • Saves a lot of time and hassle-free to maintain
  • Enhanced performance compared to other apps
  • The code can be used in all other mobile platforms

4) What are disadvantages of hybrid apps?

The main disadvantages of hybrid applications are as follows.

  • Hybrid apps require a full-fledged internet connection for the delivery of all features of the application.
  • It includes limited capabilities because they rely mostly on the plugins that can be unreliable and outdated.
  • The user experience for the hybrid apps is poor as if you concentrate more on Android, iOS users will be unsatisfied. And if you focus more on iOS android users will face the worst experience.
  • For the development of the native apps, you will require native developers only.
  • Some of the hybrid apps include hidden errors that affect their performance.

5) What is difference between native app and hybrid app?

Difference between Native app and Hybrid app

Hybrid apps are a type of native application only as they can be downloaded from the application store of the platform. Hybrid apps are created using web languages like CSS, HTML5, and JavaScript. It mainly runs in the web view that displays the pages of the app using the same engine browser but no widget.

A native application is a program or software that has been created to operate some particular tasks on a specific platform or environment. Native apps implement software development tools (SDK) for a certain hardware platform or a software framework. Native plugins are necessary to allow the native features like a mic, camera, etc.

6) What is full form of ANR?

The full form of ANR is Application Not Responding. ANR describes that an android app is not working properly. When an app is running on the Android platform and suddenly stops responding, that is when the ANR event is triggered. A dialog box appears on the screen if there is an ANR error in the app. The message will indicate that the app is not working properly and ask the user if they want to shut down the app. Two situations might have caused the ANR error and they are:

  • If an active app is not responding to an input event within five seconds
  • The BroadcastReceiverClass has not completed its execution even after a long time

7) What are major plateforms supported by Hybrid App?

Topmost Hybrid Mobile App Frameworks are as below:

  • Xamarin: Xamarin stands one of the important mobile application advancement frameworks that has remained employed in several of the Foundations for a very genuine reason, above 1.4 million developer’s active association around the globe.
  • React Native: one of the principal objectives of this structure is to generate native applications above hybrid applications that operate on a web-view.
  • Onsen UI: Onsen UI remains an open-source mobile application improvement structure that is fully provided to be utilized sans the Angular JS specification.
  • Ionic: ionic holds a very leading structure and also recognized as the favored option of the largest of the developers. CSS parts of the structure are sufficient to generate native-looking applications.
  • Framework7: similar to the other structures, this holds by far the usual durable and individualistic structure – as this does not own any dependence on AngularJS or React.
  • PhoneGap: PhoneGap comprises yet added open-source portable application improvement structure and is further recognized as the easiest cross-platform structure.

Using a C# shared codebase, designers can use Xamarin services to write native Android and Windows apps with UIs and distribute code across multiple platforms, including Windows and Linux.

jQuery Mobile Interview Questions

JQuery Mobile is an HTML5-based UI framework, developed on jQuery Core and utilized for developing responsive websites or applications that are accessible on mobile, and desktop devices and relies on JavaScript programming language. Moreover, it uses features of both jQuery and jQuery UI to implement API features for mobile web applications. Other than assigning distinct frameworks for individual OS, the jQuery mobile framework enables to produce a single responsive application that will work on almost all smartphone and desktop platforms.

Cordova Interview Questions

Apache Cordova previously PhoneGap is a mobile application project framework by Nitobi that enables application programmers to develop applications for mobile devices using CSS3, HTML5, and JS rather than relying on platform-specific APIs like those in Android, iOS or Windows phone and also, it facilitates wrapping up of CSS, HTML, and JS code depending upon the platform of the device in addition to extending the features of HTML and JavaScript to work with the device. Thereby, the resulting applications are hybrid, meaning that they are neither exactly native mobile applications nor purely Web-based.

IONIC Framework Interview Questions

Ionic is an open-source software development kit for the hybrid mobile application created by Lynch, Sperry, and Adam Bradley in 2013 and built above AngularJS and Apache Cordova. However, the newest release was re-built as a set of web elements, allowing the client to choose any user interface framework, such as Angular, React or Vue.js and also allows the use of Ionic elements with no GUI. Ionic provides services for developing hybrid web applications based on developing technologies and practices, using Web technologies like CSS, HTML5, and Sass. To be specific, mobile apps can be built with these Web technologies and then spread through native app stores to be established on devices using Cordova.
