The getUUID() function in ngCordova is causing an error where the device is

Getting 'device is not defined' error with ngCordova getUUID()

In the process of developing a mobile app using Ionic framework, I encountered an issue with retrieving the device UUID. To tackle this problem, I decided to leverage ngCordova by incorporating the minified version available at ngCordova.

Below is an excerpt from my main module:

angular.module('starter', ['ionic','ngCordova'])
.controller('test',function($scope,$cordovaDevice){
$scope.uuid=$cordovaDevice.getUUID();
console.log($cordovaDevice)
})

Although $cordovaDevice appears as an object when inspected through console.log, invoking $cordovaDevice.getUUID() triggers an error stating 'device is not defined'. Any insights on resolving this issue would be greatly appreciated.

Answer №1

Did you add the cordovaDevice plugin using the following command?

cordova plugin add org.apache.cordova.device

Answer №2

We recommend holding off until the device is fully prepared...

document.addEventListener("deviceready", function() {
    $scope.isOnline = $cordovaNetwork.isOnline();
    $scope.UUID = $cordovaDevice.getUUID();
}, false);

Answer №3

To resolve this issue, I added $scope.$apply() after invoking $cordovaDevice.getUUID()

$ionicPlatform.ready(function() {

    if(ionic.Platform.isAndroid()) {
      $scope.account.imei =  $cordovaDevice.getUUID();
      $scope.$apply();

    }else {//For ionic serve
        $scope.account.imei = '12345';
        console.log($scope.account.imei);
    }
});

According to the official documentation , the cordova plugin returns a promise.

$ionicPlatform.ready(function() {
   $cordovaPlugin.someFunction().then(success, error);
});

Answer №4

You have correctly defined ngCordova as a module dependency. Simply inject $cordovaDevice into your controller using the full array syntax.

.controller('example',['$scope', '$cordovaDevice', function($scope, $cordovaDevice){
$scope.UUID = $cordovaDevice.getUUID();
}])

If this method doesn't work, make sure that the plugin is loading properly in your application.

Answer №5

The reason for this error is that you are trying to access a device's details while working on your local machine.

Upon examining the functions, it becomes apparent that none of them will provide accurate information in your development environment. Cordova is specifically designed for mobile devices and does not have handlers set up for local development.

  • This function returns the entire device object: getDevice()

  • Use getCordova() to retrieve the Cordova version.

  • For the name of the device's model or product, use getModel()

  • getPlatform() will give you the device's operating system name

  • To obtain the device's Universally Unique Identifier, call getUUID()

  • Lastly, getVersion() returns the operating system version.
