navigator.camera.getPicture doesn’t call success callback - ionic framework - cordova

问题

I am using navigator.camera for taking pictrues. The success and error call back is not getting called most of the time. I have installed cordova camera plugin

I am using

ionic 1.2.8

cordova 3.5.0-0.2.7

org.apache.cordova.camera 0.3.3 "Camera"

Shown below is the code I use.

$scope.takePicture =  function takePicture()    {
    var success = function onSuccess (FILE_URI){
    console.log("something" + FILE_URI)
    console.log(FILE_URI);
    $localstorage.setObject("file",FILE_URI);
    $rootScope.picData = FILE_URI;
}

var error = function onError () {
    console.log("Error")
    alert("error")
}

console.log("Taking picture");
navigator.camera.getPicture(success,error,{
            quality: 50,
            destinationType: navigator.camera.DestinationType.FILE_URI,
            sourceType: navigator.camera.PictureSourceType.CAMERA
        });

};
