Implementing Camera API in Phonegap

In this exercise today we will be implementing camera API in Phonegap where we will create two buttons namely Take Photo and Get Photo which will access the camera and the photogallery.

  • So to start working with the camera api follow the steps given below :

  1. Install the Xampp server in your machine and if it is already installed then go to Xampp->htdocs folder.
  2. In htdocs folder create a new folder called as Camera .
  3. In this Camera folder create an html document called as index.html
  4. Now open your index.html file in any text editor and write the following html code in it :
  5. <!DOCTYPE html>
            <title>PhoneGap Application</title>
            <script type="text/javascript" src="cordova.js"></script>
            <script type="text/javascript" src="js/main.js"></script>
            <!--button for capturing a photo-- >
            <button onclick="takePhoto();">Take A Photo</button> <br>
            <!--button for accessing the  photo library-- >
            <button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">Get a Photo</button><br>
             <!--Displaying the image captured to put to data--> 
            <img style="display:none;width:200px;height:190px;" id="dataImage" src="" />
            <!--Displaying the image to be accessed from the source file-->
            <img style="display:none;width:200px;height:190px;" id="uriImage" src="" />

  6. So after writing the code you will have the following look out of your text editor :
  7. 1

  8. Now in the Camera folder create a new folder called as js .
  9. In this js folder create a new text document called as main.js i.e save it with type as js .
  10. Now open this main.js file with any text editor window and write the following code in it :
  11. var pictureSource;    //Source var
    var destinationType;  //Destination var
    //Add event listener to run when the device is ready
    document.addEventListener("deviceready", onDeviceReady, false);
    //Device is ready
    function onDeviceReady() {;;
    //Will run if data photo is taken
    function onPhotoDataSuccess(imageData) {
        //Set image handler
        var dataImage = document.getElementById('dataImage');
        //Unhide = 'block';
        // Show photo from data
        dataImage.src = "data:image/jpeg;base64," + imageData;
    //Will run if url photo is taken
    function onPhotoURISuccess(imageURI) {
        //Set image handler
        var uriImage = document.getElementById('uriImage');
        // Unhide image elements = 'block';
        //Show photo from uri
        uriImage.src = imageURI;
    //Capture picture
    function takePhoto() {
        // Take picture using device camera and retrieve image as base64-encoded string, onError, {
            quality: 50,
            destinationType: destinationType.DATA_URL
    //Get photo from gallery
    function getPhoto(source) {
        // Retrieve image file from gallery
  , onError, {
            quality: 50,
            destinationType: destinationType.FILE_URI,
            sourceType: source
    function onError(message) {
        alert('Error: ' + message);

  14. Hence after writing the code save your document and now sign in into your Github account by visiting :
  15. 0

  16. So now enter a username ,your email id and password in the respective tabs and click on the Sign up for GitHub button .
  17. After you click on the signup button you will get the following window :

  19. Now click on the ‘+’ icon on the right hand side as indicated by the red arrow and then click on the “ New repository ” as indicated by the blue arrow .
  20. 0.2

  21. After clicking on the New repository you will be navigated to the next window ,specify a Repository name ,select a public radio button and click on the Create repository button as shown in the image below :
  22. Implementing Camera API in Phonegap0.3

  23. So after clicking on the Create repository button you have the following window :
  24. Implementing Camera API in Phonegap0.4

  25. Go to xampp -> htdocs .
  26. In htdocs you have your Camera folder created .
  27. Now go to your start menu -> GitBash -> right click on it -> Send To -> Desktop (create a shortcut) of GitBash on Desktop as shown below :
  28. Implementing Camera API in Phonegap0.7

  29. So now on Desktop you will have a GitBash icon .
  30. Now Right Click on the GitBash icon on the desktop and go to properties and in the Start in edit box set the path as : c:xampphtdocs as shown in the image.
  31. Implementing Camera API in Phonegap0.8

  32. Now Click on Apply and OK button .
  33. Now start the GitBash application from the desktop and you will have the following screen :
