我们无法重新创建此问题。

重新创建的步骤 -

使用的代码 -

function onClickB(){

        navigator.camera.getPicture(onSuccess, onFail, {
        quality : 20,
        destinationType : navigator.camera.DestinationType.DATA_URL,
        sourceType : navigator.camera.PictureSourceType.PHOTOLIBRARY
      });


    function onSuccess(imageData){
       alert(imageData.length);
       var VarUsedtoSendToAdapter=imageData;
    }

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

}

试验1：

环境 -

IBM MobileFirst studio - 6.3.0.00-20141127-1357 Visual Studio Professional 2013 Update 2 目标 - Windows Phone 8.0

试验2：

IBM MobileFirst studio - 6.3.0.00-20150214-1702 Visual Studio Professional 2013 Update 2 目标 - Windows Phone 8.0

结果（两次试验中） -

1）设备1 - 诺基亚Lumia 1520 - WP 8.1更新1

   Library launches, we select file , length is alerted. 
   The message -"System.NullReferenceException' occurred in worklight-windowsphone8.DLL" does not appear

2）设备2 - HTC 8x（Windows 8.0

    Library launches, we select file , length is alerted. 
   The message -"System.NullReferenceException' occurred in worklight-windowsphone8.DLL" does not appear

使用来自相册和相机胶卷的不同文件大小的多张图片进行测试，结果相同。

问题：

1）在Mobile First 6.3工作室上新创建的项目是否会出现问题？

2）项目是否迁移到6.3？如果是这样，您可以尝试删除WP 8环境并再次添加吗？

Work.NullReferenceException'发生在worklight-windowsphone8.DLL中并关闭应用程序
