cordova-plugin-camera无法在Crosswalk Android上工作（适用于iOS）

我有一个离子（cordova / phonegap）应用程序，其中包括上传从设备相机或照片库中拍摄的照片 . 我通过ngCordova使用cordova插件，包括 cordova-plugin-camera 和 cordova-plugin-file .

Android版本使用 CrossWalk engine .

我可以从库中选择图像或拍摄新照片 . 但是我的回调是't called so I' m无法使用结果 . N.B: everything works perfectly on iOS.

回调（未调用如下）回调位于'then'方法中 .

$scope.getPhoto = function(useLibarary) {
        var options = {
            destinationType: Camera.DestinationType.FILE_URI,
            sourceType: (useLibarary) ? Camera.PictureSourceType.PHOTOLIBRARY : Camera.PictureSourceType.Camera,
            encodingType: Camera.EncodingType.JPEG
        };

       $cordovaCamera.getPicture(options).then(function(imageURI) {
            // success
            //
            $scope.postImageSrc = imageURI;
            console.log(JSON.stringify(imageURI));

            $scope.imageURI = imageURI;

        }, function(err) {
            // error
            console.log("error: " + JSON.stringify(err));
        });

        $cordovaCamera.cleanup().then(
            function() {
                console.log("cleanup done");
            }); // only for FILE_URI
    };

我需要帮助才能让它在Android上运行 .

我已经在仿真器和真实设备上进行了测试 .

Cordova版本：5.4.1
