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.
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.

The major platforms that are supported by the Hybrid App are Ionic Framework,JQuery Mobile, Xamarin, React Native, Onseen UI, PhoneGap, Framework7, Intel XDK, Appcelerator Titanium, Mobile Angular UI, Sencha Touch, jQuery Mobile, Mobincube, Longrange, Qt, Alpha Anywhere, NativeScript, Firebase, Swiftic, VuForia
There are many advantages to hybrid applications. Below are a few of them discussed:
The main disadvantages of hybrid applications are as follows.
Difference between Native app and Hybrid app
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.
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:
Topmost Hybrid Mobile App Frameworks are as below:
Appcelerator is a confidentially held mobile technology company based in California and its principal products are Titanium, a free software development kit for cross-platform mobile development, and the Appcelerator Platform, software that produces cross-platform native mobile app development using JS, mobile backend as a service (MBaaS), mobile test automation, crash detection, and performance management, and mobile analytics. Founded in 2006, Appcelerator assists industries including; retail, financial services, healthcare, and government.
Xamarin is Microsoft's software company established in 2011 by creators of Mono, Xamarin.Android and Xamarin.iOS, which are multi-platform implementations of the Common Language Infrastructure (CLI) and Common Language Specifications. 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.
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.
PhoneGap is a mobile app development framework by Adobe Systems, which is used to produce mobile applications. To develop apps employing PhoneGap, the developer does not need to know mobile coding language but only web-development languages like HTML, CSS, and JS. It produces apps for all modern mobile OS platforms such as iOS, Android, BlackBerry, and Windows Mobile OS.
