5. Sample PhoneGap Developer Interview Questions and Answers

Explore these sample questions with detailed answers to assess candidates’ PhoneGap skills:

Q1. Explain the structure of a PhoneGap project and its main components.


<!-- Sample Answer: Structure of a PhoneGap project -->












Q2. How does PhoneGap handle device-specific features and APIs?


PhoneGap uses plugins to access device-specific features and APIs. For example, to access the camera, you might use the Camera plugin:

// Sample Answer: Using Camera plugin, onFail, { quality: 50 });

function onSuccess(imageData) {

 console.log('Image URI: ' + imageData);


function onFail(message) {

 console.log('Failed because: ' + message);



Q3. Implement a PhoneGap application that makes a REST API call to retrieve data and display it on the screen.


// Sample Answer: Making a REST API call in PhoneGap


 .then(response => response.json())

 .then(data => {

 document.getElementById('result').innerText = JSON.stringify(data);


 .catch(error => console.error('Error:', error));


Q4. What are the key differences between PhoneGap and Cordova?


PhoneGap and Cordova are essentially the same. Adobe PhoneGap is built on the open-source Apache Cordova project. PhoneGap includes additional tools and services, but the core of both is the same.

Q5. Explain the purpose of the config.xml file in a PhoneGap project.


The config.xml file in a PhoneGap project is a configuration file that contains settings for the app, such as the app’s name, description, version, and permissions. It also defines preferences, plugins, and icons used by the app.

Q6. How does PhoneGap handle offline storage in mobile applications?


PhoneGap provides the Web Storage API (localStorage and sessionStorage) for client-side storage. Additionally, developers can use plugins like Cordova SQLite for more advanced offline storage capabilities, allowing the app to store data in a local database.

Q7. Create a simple PhoneGap plugin that displays a native toast notification.


// Sample Answer: PhoneGap plugin for toast notification

var ToastPlugin = {

 showToast: function (message, duration, successCallback, errorCallback) {

 cordova.exec(successCallback, errorCallback, 'ToastPlugin', 'showToast', [message, duration]);




Q8. How does PhoneGap handle responsiveness and adapt to different device screen sizes?


PhoneGap leverages responsive design principles using CSS media queries to adapt the layout and styles based on the device’s screen size. Developers can create a flexible and responsive UI that adjusts seamlessly across various devices.

Q9. Explain the purpose of the PhoneGap Build service.


PhoneGap Build is a cloud service that allows developers to build PhoneGap apps in the cloud without the need to install SDKs locally. It simplifies the build process, making it easier to compile apps for multiple platforms.

Q10. Write a PhoneGap application that uses the device accelerometer to detect motion.


// Sample Answer: PhoneGap application using accelerometer

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {

 navigator.accelerometer.watchAcceleration(onSuccess, onError, { frequency: 1000 });


function onSuccess(acceleration) {

 console.log('Acceleration X: ' + acceleration.x +

 ' Y: ' + acceleration.y +

 ' Z: ' + acceleration.z);


function onError() {

 console.error('Accelerometer error.');
