Cordova/Phonegap moveTo不能獲取根目錄

這是一個正在調用的onSuccess函數，但moveTo方法沒有達到預期的效果。它應該將我的映像移動到file：/// storage/sdcard0/PhotoscanPhotos /，但調試警報僅顯示//PhotoscanPhotos。Cordova/Phonegap moveTo不能獲取根目錄

function movePhoto(fileEntry) { 
     window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, 
      function(fileSys) { //onsuccess 
       fileSys.root.getDirectory("PhotoscanPhotos", {create: true, exclusive: false}, function(dir) { 
        var guid = guidGenerator(); 
        Speicher.setPhotoFolder(dir.fullPath); 
        alert(dir.fullPath); //debugging 
        fileEntry.moveTo(dir, (guid + "foto.jpg"), onMoveSuccess, onFail); 
       }, onFail); 
      }, onFail); 
    }

任何人都知道我做錯了什麼？這是來自Phonegap 3.1 API文檔的虛擬副本。我肯定有我的配置文件正確。

在此先感謝

編輯：爲完整代碼的休息：

function takePicture() { 
     var code = $("#txtCode").val(); 
     if(!code){ 
      alert("Zuerst EAN-Code scannen oder eingeben."); 
      return false; 
     }else{ 
      ean = code; 
     } 
     navigator.camera.getPicture(onPhotoURISuccess, onFail, 
      { quality: 100, destinationType: Camera.DestinationType.FILE_URI }); 
     return true; 
    } 

    function onPhotoURISuccess(imageURI) { 
     createFileEntry(imageURI); 
     showImageList(); 
    } 

    function createFileEntry(imageURI) { 
     window.resolveLocalFileSystemURI(imageURI, movePhoto, onFail); 
    } 



    function movePhoto(fileEntry) { 
     window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, 
      function(fileSys) { //onsuccess 
       fileSys.root.getDirectory("PhotoscanPhotos", {create: true, exclusive: false}, function(dir) { 
        var guid = guidGenerator(); 
        Speicher.setPhotoFolder(dir.fullPath); 
        alert(dir.fullPath); //debugging 
        fileEntry.moveTo(dir, (guid + "foto.jpg"), onMoveSuccess, onFail); 
       }, onFail); 
      }, onFail); 
    } 

    function onMoveSuccess(entry) { 
     var image = {ean:ean, image: entry.fullPath, timestamp:convertDateToUTC()}; 
     alert(image.image); //debugging 
     getPhotoFolder(); 
     alert(numOfPhotosStored + " photos stored"); //debugging 
     images.push(image); 
     Speicher.setImages(images); 
     showImageList(); 
    } 

    function onFail(error) { 
     alert(error.code + error.message); 
    }
