1. What is Cordova?

It’s a framework that allows building mobile applications using programming languages like Java Script HTML5 and CSS3. Most programming languages aren’t capable of working with native device functionalities like GPS, Contacts, and cameras. That explains why Cordova acts as a processor for running web-based applications. Sometim4s, Cordova is also known as Phone gap.

2. What operating Cordova supports systems?

Almost all major operating systems are supported, but to be certain, its best compatible with BlackBerry 10, Firefox OS, Windows 8, Windows Phone, Amazon Fire OS, Android, Ubuntu, iOS, and Tizen; however, users have to install the Command-line interface from Cordova to enable them to create a safe environment for use in the operating system listed above. 

3. What are Cordova events?

These are activities carried out when using Cordova. Numerous Cordova events can be used in any Cordova project, depending on the nature of your project. They include

  • Pause: it’s an event that occurs whenever an application is placed in the background. 
  • The back button occurs when the user presses the back button.
  • Search button: when you press the search button on an android phone, it will create a search button event
  • Device Ready: it’s an event that occurs when Cordova is fully loaded. It ensures we don’t call the Cordova function before fully loading it.
  • Resume: this event will occur when the application in the background is removed
  • Menu button: this event is created when you press the menu button
  • End call button: an event created when one presses the end call button
  • Start call button: it’s an event created when one presses the start call button
  • Volume up button: it’s a Cordova event created when the volume up button is pressed
  • Volume down button: it’s an event created when you press the volume down button

4. What are Cordova’s features?

  • Cordova CLI: also known as a command-line interface, which is a key feature of Cordova. Its mainly used for developing processes for various platforms, starting new projects, and installing plugins and other functionalities that make it easier for developers to use Cordova. 
  • Cordova core components: this feature offers all the components required by every mobile application. They aid in creating a base of a phone application. 
  • Cordova plugins: plugins offer an application programming interface (API) that’s used during the implementation of native mobile functions
  • License: Cordova is protected by Apache license V2.0

5. What Is Cordova Plug man?

It’s a command-line tool used for the installation and management of plugins. This feature is used by developers who need to run a given application on a given platform. If the user needs a cross-platform phone application, then Cordova-CLI is an alternative command line for modifying plugins on various platforms. 

6. What is the advantage of using Cordova?

Cordova has several advantages that developers may enjoy, but the main one includes

  • It’s easier to build an application using Cordova than the native applications. It, therefore, saves a lot of time and struggle. 
  • It provides a single platform used to develop hybrid mobile apps. As a result, developers may program an application capable of running on several mobile platforms like Android Amazon-fireOS, Firefox OS, Tizen, Ubuntu windows phone, and iOS. 
  • With extensive community add-ons, programming an application is easier and most efficient. Furthermore, the availability of framework and libraries allow easy optimization. 
  • When the developer is using JavaScript in conjunction with Cordova, there won’t be necessary to analyze the targeted platform’s programming language.

7. What are the elements of the Cordova config.xml file? 

config.xml file creates an environment for altering application configurations. Its elements include

  • Widgets: this entails the reverse domain value
  • Description: all the information describing the app
  • Name: features the uniquely specified application name
  • Author: gives the information about the application author
  • Plugin: there are the plugins that have been installed
  • Platform: this includes the apps platform name
  • Content: it’s the starting page of the mobile application
  • Access: here is where you find control as far as accessing the external domain is concerned

8. What is the difference between PhoneGap and Cordova?

Adobe developed PhoneGap and later handed its database over to Apache to keep it open source and adhere to the standards. PhoneGap is currently known as Apache Cordova. In simple terms, it’s a distribution of Cordova and acts as an engine that powers PhoneGap. In the same way, WebKit †“powers safari and chrome browsers. 

What are the limitations of using Cordova?

  • Most hybrid apps developed using Cordova run slower compared to native apps.
  • It’s time-consuming to test and optimize apps developed by Cordova because the developer we’ll need to cover several operating systems. 
  • Browser compatibility may be an issue when dealing with Cordova applications.

9. What are device installer formats?

Different types of device installer formats vary depending on the type of operating system. However, the common device installer formats 


  • Android: Android Application package (.apk)
  • iOS: iPhone Application Archive (.ipa)
  • Windows Phone: Silverlight application package (.xap)

10. What can you tell us about PhoneGap architecture?

PhoneGap contains plugin-based architecture, and every feature of plugins are device specifics. However, it features both the native sides and the java scripts. The JavaScript side is supposed to be compatible with as many platforms as possible. But the developer can implement the native side only once.

Normally, build-in plugins are readily optimized for many platforms, and one depends needs to re-invent them again. Using this architecture and the open-source code, developers can easily and swiftly fix app bugs and alter the plugin functionalities to enable it to serve a particular task. Additionally, developers are capable of building their plugins and as well support any platform they choose. 

11. What platforms are supported by PhoneGap?

Many platforms are supported by the Phone gap, including but not limited to iPhone / iPhone 3G and Newer, Web OS, Windows Phone 7, Bada, Android, Tizen, Symbian, and Blackberry OS 5. x, and Higher

12. What is a data subject?

According to Cordova, the data subject is an identifiable or identified individual to whom the personal information relates. It can be direct or indirect where we use indefinable numbers or factors like mental, physical, cultural, economic, or social identity.

13. What is Cordova media?

Cordova media aids in recording and playing audio in Cordova applications. One can implement Cordova media by the installation of Cordova media

14. What is Cordova Camera?

This functionality in Cordova allows the taking of pictures or the use of images from the phone’s gallery. The programmer needs to install the Cordova camera plugin to use this feature. 

15.  Explain the Cordova mechanism

The interface of the Cordova application is a technical and effective WebView that engages the whole screen and operates in the inbuilt (native container). It’s therefore resembling the WebView used by the native operating system. Only the native container can be altered per the OS, but the webpages will always remain unchanged.

Again, the web browser’s information varies from page to page. For instance, iOS – UIWebView class, Android – Android.WebKit.webview and windows – WebViewClass

16. What are the limitations of PhoneGap?

  • PhoneGap is not suitable for intensive graphics and complex games; OpenGL would be a better option
  • When working with slower phones (iPhone, Xperia X10, and Nexus One excluded), the PhoneGap apps that use google maps tend to be slower. But using static maps would be a better option.

17. How does Cordova manipulate the file system?

We can manipulate Cordova file systems only when we install the file plugin, also known as Cordova-plugin-file.

18. What’s the Cordova back button?

It’s the built-in functionality of a back button that returns the previously accessed screen. However, we can implement a unique functionality whenever a back button is pressed.

19. Is Cordova still relevant today?

Cordova is a container for applications developed using web technologies. Whenever you compile your application, the source code will remain unchanged. The compiler takes the code and avails it for web view, thus enabling rendering. It’s similar to opening an HTML file in a web browser.

20. What do you require to embed WebView?

the prerequisites for embedding WebView include Cordova 3.3.0 or higher, Amazon WebView SDK, and Android SDK (updated to SDK 3 latest version)

21. How do you create a Cordova dialog box?

Before you can create a Cordova dialog box, we need a Cordova dialog plugin which can be done easily using the command.  

C:\Users\username\Desktop\CordovaProject>cordova plugin add Cordova-plugin-dialogs

22. What is the best way to handle device-specific needs?

The most important factor to consider is the future set. But generally, many mobile apps don’t require device-specific features more than the user interface. However, there are a ton of Cordova plugins that can be useful in such circumstances. Therefore, it’s important to determine the most important features you need. Many phone applications where the permission is set to on even though that permission isn’t required.

23. What can you say about Cordova and PhoneGap?

Cordova and PhoneGap are the same things. to be precise, Apache Cordova is the engine that powers PhoneGap

24. Can you display the battery status of the mobile device?

Using Cordova, it’s possible to show the information about the phone’s battery. But again, just like other functionalities, we need to install a battery plugin that keeps track of changes on the device battery.

25. How does Cordova work internally?

It’s an open-source framework that allows programmers to convert JavaScript, cascading style sheets (CSS), and HTML into native applications capable of running on Android, iOS, and other mobile platforms

26. What kind of platform is Cordova?

It’s a mobile application development environment (framework) that enables developers to create cross-platform apps using pure javascript and html5

27. Who are the original authors of Apache Cordova?

Joel bower, Michael brooks, Dave Johnson, rob Ellis, Jesse MacFayden, anis Kadri, Filip Maj, and brock Witten are among the authors of Apache Cordova.

28. To set the current plugman registry URL, which command should you use?


29. Which OS is supported by Android SDK?

Android SDK supports OS X, Windows, and Linux

30. What is the role of the config.xml file in the Cordova project?

It creates a platform for enabling the alteration of the app’s configuration.
