PhoneGap Camera Plugin

First off, in the terminal navigate to the root directory of your phone gap application. Next run this command to install the camera app dependencies:

cordova plugin add cordova-plugin-camera

. You may also need to navigate to the plugin’s folder and run

npm install


Your index.js file should look a little something like this:

// This state represents the state of our application and will be saved and
// restored by onResume() and onPause()
var appState = {
takingPicture: true,
imageUri: ""

var APP_STORAGE_KEY = "exampleAppState";

var app = {
initialize: function() {
bindEvents: function() {
// Here we register our callbacks for the lifecycle events we care about
document.addEventListener('deviceready', this.onDeviceReady, false);
document.addEventListener('pause', this.onPause, false);
document.addEventListener('resume', this.onResume, false);
onDeviceReady: function() {
document.getElementById("take-picture-button").addEventListener("click", function() {
// Because the camera plugin method launches an external Activity,
// there is a chance that our application will be killed before the
// success or failure callbacks are called. See onPause() and
// onResume() where we save and restore our state to handle this case
appState.takingPicture = true;

navigator.camera.getPicture(cameraSuccessCallback, cameraFailureCallback,
sourceType: Camera.PictureSourceType.CAMERA,
destinationType: Camera.DestinationType.FILE_URI,
targetWidth: 250,
targetHeight: 250
onPause: function() {
// Here, we check to see if we are in the middle of taking a picture. If
// so, we want to save our state so that we can properly retrieve the
// plugin result in onResume(). We also save if we have already fetched
// an image URI
if(appState.takingPicture || appState.imageUri) {
window.localStorage.setItem(APP_STORAGE_KEY, JSON.stringify(appState));
onResume: function(event) {
// Here we check for stored state and restore it if necessary. In your
// application, it's up to you to keep track of where any pending plugin
// results are coming from (i.e. what part of your code made the call)
// and what arguments you provided to the plugin if relevant
var storedState = window.localStorage.getItem(APP_STORAGE_KEY);

if(storedState) {
appState = JSON.parse(storedState);

// Check to see if we need to restore an image we took
if(!appState.takingPicture && appState.imageUri) {
document.getElementById("get-picture-result").src = appState.imageUri;
// Now we can check if there is a plugin result in the event object.
// This requires cordova-android 5.1.0+
else if(appState.takingPicture && event.pendingResult) {
// Figure out whether or not the plugin call was successful and call
// the relevant callback. For the camera plugin, "OK" means a
// successful result and all other statuses mean error
if(event.pendingResult.pluginStatus === "OK") {
// The camera plugin places the same result in the resume object
// as it passes to the success callback passed to getPicture(),
// thus we can pass it to the same callback. Other plugins may
// return something else. Consult the documentation for
// whatever plugin you are using to learn how to interpret the
// result field
} else {

// Here are the callbacks we pass to getPicture()
function cameraSuccessCallback(imageUri) {
appState.takingPicture = false;
appState.imageUri = imageUri;
document.getElementById("get-picture-result").src = imageUri;

function cameraFailureCallback(error) {
appState.takingPicture = false;


You can copy and paste the above code, it’s the base of the index.js file with the camera functionality. The corresponding html for whatever page you want to call the camera event on is:


As I progress with my PhoneGap development I will update this document and elaborate on the camera app plugin and how it works. For now I am simply playing with the plugins and documenting my progress.
