Question

我遇到了Phonegap FileTransfer API的问题。目前我正在尝试运行以下示例代码：

        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，似乎没有任何事情发生。没有标记错误，并且回调似乎没有被触发。我得到的只是“功能正在呼唤”的初始console.log。

我已经仔细检查了，并且可以确认我包含了cordova js文件，（cordova-2.4.0.js）。

如果重要的话，我在Android模拟器，HTC One X和三星Galaxy S3上尝试了这一点，结果都相同。

有谁知道造成这种情况的原因是什么？

编辑：我也觉得我应该提到它也在Angular JS应用程序中运行。

这就是我在项目中的表现

 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);
            }
        )
    }

尝试这样，让我知道。

Phonegap FileTransfer似乎在android中什么都不做
