Use the device’s library, camera and microphone to work with local audio, video
and images.
Camera, Capture & Mediafunction onSuccess(imageData) { // Do stuff with the image!
}
function onFail(message) {
alert('Failed to get the picture: ' + message);
}
var cameraPopoverHandle = navigator.camera.getPicture(onSuccess, onFail, { destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY });
! // Reposition the popover if the orientation changes.
window.onorientationchange = function() {
var cameraPopoverOptions = new CameraPopoverOptions(0, 0, 100, 100, 0);
cameraPopoverHandle.setPosition(cameraPopoverOptions);
}

Contacts// Wait for device API libraries to load
//
document.addEventListener("deviceready", onDeviceReady, false);

InAppBrowser
The browser opened by window.open()
Extremely useful to open external links!
InAppBrowservar ref = window.open('http://apache.org', '_blank', ‘location=yes');
!// close InAppBrowser after 5 seconds
setTimeout(function() {
ref.close();
}, 5000);
