phonegap图片下载没有错误

Question

这是我的代码：

图片存在于http://www.google.com/trends/resources/2327917647-google-icon.png

我无法保存图片

它显示错误代码1 有什么问题？

function gfsuccess(fentry){

    alert(fentry.fullPath+"dircreated")

    var fileTransfer = new FileTransfer();
    var uri = encodeURI("http://www.google.com/trends/resources/2327917647-google-icon.png");

    fileTransfer.download(uri,fentry.fullPath+"/newimg.png", // //demo_folder
    function(entry) {

        alert("download complete: " + entry.toURL());
    },
    function(error) {

        alert("download error source " + error.source);
        console.log("download error target " + error.target);
        console.log("upload error code" + error.code);
    }, 
    false, {

        headers: {
            "Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
        }
    });
}

function gotfs(fs){

    alert("gotfs"+fs);
    fs.root.getDirectory("demo_folder", {create: true, exclusive: false},gfsuccess,errorHandler);
}

function errorHandler(e){

    alert("Files system error"+e.code);
}
function onDeviceReady() {

    alert("device ready"+navigator.connection.type);
    //external root dir: file:///storage/sdcard0/
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 20*1024*1024/*5MB*/, gotfs, errorHandler);
}

function domLoaded(){

    alert("dom loaded");
    document.addEventListener("deviceready", onDeviceReady, false);
} 

文件夹创建正常，但我似乎无法获得图像..不知道这里发生了什么
