Device

Device

The device object describes the device's hardware and software.

Properties

Variable Scope

Since device is assigned to the window object, it is implicitly in the global scope.

// These reference the same `device`
var phoneName = window.device.name;
var phoneName = device.name;

iPhone Quirks

The iPhone returns iPhone as the platform. The iPad returns iPad as the platform. In the simulator they will return iPhone Simulator and iPad Simulator respectively. These are inaccurate in all cases because Apple has rebranded the iPhone operating system as iOS.

BlackBerry Quirks

Devices may return the device platform version instead of the platform name. For example, the Storm2 9550 would return '2.13.0.95' or similar.

Windows Phone 7 Quirks

Windows Phone 7 devices report platform as 'WinCE'


device.uuid

Get the device's Universally Unique Identifier (UUID).

var string = device.uuid;

Description

The details of how a UUID is generated are determined by the device manufacturer and specific to the device's platform or model.

Supported Platforms

Quick Example

// Android: Returns a random 64-bit integer (as a string, again!)
//          The integer is generated on the device's first boot
//
// BlackBerry: Returns the PIN number of the device
//             This is a nine-digit unique integer (as a string, though!)
//
// iPhone: (Paraphrased from the UIDevice Class documentation)
//         Returns a string of hash values created from multiple hardware identifies.
//         It is guaranteed to be unique for every device and cannot be tied
//         to the user account.
// Windows Phone 7 : Returns a hash of device+current user, 
// if the user is not defined, a guid is generated and will persist until the app is uninstalled
// 
// webOS: returns the device NDUID
var deviceID = device.uuid;

    <title>Device Properties Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova-1.9.0.js"></script>

    //
    function onDeviceReady() {
        var element = document.getElementById('deviceProperties');

        element.innerHTML = 'Device Name: '     + device.name     + '<br />' + 
                            'Device Cordova: '  + device.cordova  + '<br />' + 
                            'Device Platform: ' + device.platform + '<br />' +

iOS Quirk

The uuid for iOS is not unique for a device, but is unique per application per install. This will change if you delete the app and re-install, and possibly also when you upgrade your iOS version, or even upgrade your app per version (as we've seen in iOS 5.1). Not a reliable value.

Windows Phone 7 Quirks

The uuid for Windows Phone 7 requires the permission IDCAPIDENTITY_DEVICE. Microsoft will likely be deprecating this property in the near future. If the capability is not available, the application generates a persistent guid, that will be maintained for the install-lifetime of the application on the device.


device.version

Get the operating system version.

var string = device.version;

Supported Platforms

Quick Example

// Android:    Froyo OS would return "2.2"
//             Eclair OS would return "2.1", "2.0.1", or "2.0"
//             Version can also return update level "2.1-update1" 
//
// BlackBerry: Torch 9800 using OS 6.0 would return "6.0.0.600"
//
// iPhone:     iOS 3.2 returns "3.2"
//
// Windows Phone 7: returns current OS version number, ex. on Mango returns 7.10.7720
// webOS: webOS 2.2.4 return 2.2.4
var deviceVersion = device.version;
