This tutorial is based on Intel XDK 1621
1) Create A New Project
1-1) Click PROJECTS
1-2) Click START A NEW PROJECT
1-3) Select START WITH A TEMPLATE and then select BLANK CORDOVA STARTER (LITE)
1-3) Enter Project Name
1-4) You should get Success message.
2) Add jQuery Mobile Template
2-1) Your project starts with basic files without jQuery Mobile files
The Design button is not functional at all.
2-2) Add a new html file, eg test.html
2-3) Select jQuery Framework
2-4) Add a button to the layout
2-4) jQuery Mobile library files will be automatically added to your project
2-5) Add the following lines to the index file (refer screenshot)
The Design button will automatically be activated
<link rel="stylesheet" type="text/css" href="jqm/jquery.mobile-min.css">
<link rel="stylesheet" type="text/css" href="css/test_main.less.css" class="main-less">
…
<script type="application/javascript" src="lib/jquery.min.js"></script>
<script type="application/javascript" src="jqm/jquery.mobile-min.js" data-ver="0"></script>
|
2-6) If you clear up all comment codes, you would have a nice looking codes of around 36 lines only.
3) The app.ready event
3-1) The app.ready event defined in the file init-dev.js at line no.124 is used to indicate the state at which the app has initialized all device API. At this point, calls to device API is now functional.
3-2) Copy the codes from Cordova Sample Page and add to index page
…
<body>
<p>Hello, Cordova!</p>
<button onclick="capturePhoto();">Capture Photo</button> <br>
<button onclick="capturePhotoEdit();">Capture Editable Photo</button> <br>
<button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">From Photo Library</button><br>
<button onclick="getPhoto(pictureSource.SAVEDPHOTOALBUM);">From Photo Album</button><br>
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />
<img style="display:none;" id="largeImage" src="" />
<script>
var pictureSource; // picture source
var destinationType; // sets the format of returned value
function onAppReady() {
if( navigator.splashscreen && navigator.splashscreen.hide ) { // Cordova API detected
navigator.splashscreen.hide() ;
}
if( window.intel && intel.xdk && intel.xdk.device ) { // Intel XDK device API detected, but...
if( intel.xdk.device.hideSplashScreen ) // ...hideSplashScreen() is inside the base plugin
intel.xdk.device.hideSplashScreen() ;
}
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
document.addEventListener("app.Ready", onAppReady, false) ;
// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
// Uncomment to view the base64-encoded image data
// console.log(imageData);
// Get image handle
//
var smallImage = document.getElementById('smallImage');
// Unhide image elements
//
smallImage.style.display = 'block';
// Show the captured photo
// The inline CSS rules are used to resize the image
//
smallImage.src = "data:image/jpeg;base64," + imageData;
}
// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
// Uncomment to view the image file URI
// console.log(imageURI);
// Get image handle
//
var largeImage = document.getElementById('largeImage');
// Unhide image elements
//
largeImage.style.display = 'block';
// Show the captured photo
// The inline CSS rules are used to resize the image
//
largeImage.src = imageURI;
}
// A button will call this function
//
function capturePhoto() {
// Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,
destinationType: destinationType.DATA_URL });
}
// A button will call this function
//
function capturePhotoEdit() {
// Take picture using device camera, allow edit, and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true,
destinationType: destinationType.DATA_URL });
}
// A button will call this function
//
function getPhoto(source) {
// Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
// Called if something bad happens.
//
function onFail(message) {
alert('Failed because: ' + message);
}
</script>
</body>
</html>

3-3) Add Camera Plug-in
3-5) Emulator
You can only view the User Interface but you cannot test the camera function.
This project must be compiled and installed into a real device.
