Cordova camera plugin not launching camera

问题:

I've created an Ionic app and I need the camera functionality so that a user can take a picture and send it to a webservice. I've followed the following guide by Ionic.

Basically you just cd into your applicatoin

cd myApp

then you run

cordova plugin add org.apache.cordova.camera

and once the plugin has been installed, you can invoke it's functionality where ever in your app (because according to Cordova, navigator.camera is a global object). In my case I'm just doing it in one of my controllers where the following function gets called after a button click using ng-click :

$scope.takePhoto = function() {

      navigator.camera.getPicture(function(imageURI) {

        // imageURI is the URL of the image that we can use for
        // an <img> element or backgroundImage.

      }, function(err) {

        // Ruh-roh, something bad happened


      }, cameraOptions);

    }

But it does nothing.. Now I've followed what Ionic said I must do to a 'T' and nothing more. Is there anything else I should be doing? Editing the config.xml perhaps? It's probably worth mentioning that this is the first time I've attempted in using a Cordova plugin of any sort.

I just resolved this problem by using below code,

$scope.takePhoto = function() {
    navigator.camera.getPicture(onSuccess, onFail, {
        quality: 75,
        targetWidth: 320,
        targetHeight: 320,
        destinationType: 0
    });
   function onSuccess(imageData) {
         alert('onSuccess');
         console.log("data:image/jpeg;base64,"+imageData);
    }

    function onFail(message) {
        alert('Failed because: ' + message);
    }
};

The imageData is the src of your captured image
