Phonegap FileTransfer在android

Question

中似乎什麼也不做什麼我遇到了Phonegap FileTransfer API的問題。目前，我試圖運行下面的示例代碼：

 saveFile: function (filepath,location, filetype) { 
      console.log("FUNCTION BEING CALLED"); 
      var self = this; 
      //filepath is path to the internets file 
      //location is where on the device the file will be stored 
      var fileTransfer = new FileTransfer(); 
      fileTransfer.download(filepath,self.rootPath + location + '.' + filetype, 
       function (entry) { 
        console.log('############# DOWNLOAD WORKS ##############'); 
        console.log("download complete: " + entry.fullPath); 
       }, 
       function (error) { 
        console.log('############# DOWNLOAD FAILS ##############'); 
        console.log("download error source " + error.source); 
        console.log("download error target " + error.target); 
        console.log("upload error code" + error.code); 
       } 
      ) 
     } 

目前，什麼都似乎發生。沒有錯誤被標記，並且回調似乎沒有被解僱。我所得到的是「FUNCTION BEING CALLED」的初始console.log。

我已經雙重檢查過，並且可以確認我包含cordova js文件（cordova-2.4.0.js）。

如果有問題，我已經在Android模擬器，HTC One X和三星Galaxy S3上嘗試了這一切，所有結果都一樣。

有誰知道可能是什麼原因造成的？

編輯：我也覺得我應該提到它也都運行在Angular JS應用程序中。

這就是我如何做它在我的項目

document.addEventListener("deviceready", onDeviceReady, false); 

function onDeviceReady() { 
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail); 
    } 
function gotFS(fileSystem) { 
    window.fileSystem = fileSystem; 
    //create directory test_app 
    fileSystem.root.getDirectory("test_app", { 
     create : true, 
     exclusive : false 
    }, dirWallpaper, fail); 

function fail(evt) { 

} 

function dirWallpaper(entry) { 
    //save the directory path 
    window.testDir = entry; 
} 
//now download file to that location 
saveFile: function (filepath,location, filetype) { 
     console.log("FUNCTION BEING CALLED"); 
     var self = this; 
     //filepath is path to the internets file 
     //location is where on the device the file will be stored 
     var fileTransfer = new FileTransfer(); 
     var path = window.testDir.fullPath + "/test_pdf."+ filetype; 
     fileTransfer.download(filepath,path, 
      function (entry) { 
       console.log('############# DOWNLOAD WORKS ##############'); 
       console.log("download complete: " + entry.fullPath); 
      }, 
      function (error) { 
       console.log('############# DOWNLOAD FAILS ##############'); 
       console.log("download error source " + error.source); 
       console.log("download error target " + error.target); 
       console.log("upload error code" + error.code); 
      } 
     ) 
    } 

嘗試像這樣，讓我知道。
