解决方案：

window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {

  var fileTransfer = new FileTransfer();
  var uri = encodeURI("http://www.example.com/image");
  var path = fileSystem.root.toURL() + "appName/example.jpg";

  fileTransfer.download(
    uri,
    path,
    function(entry) {
      refreshMedia.refresh(path); // Refresh the image gallery
    },
    function(error) {
      console.log(error.source);
      console.log(error.target);
      console.log(error.code);
    },
    false,
    {
      headers: {
        "Authorization": "dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
      }
    }
  );

});

我需要创建一个插件来刷新图片库，因为当你在Android设备上保存图片，此图片不会出现在图库中。此插件会更新图片库。

I needed to create a plugin to refresh the image gallery, because when you save an image on android device, this image does not appears on gallery. This plugin updates the image gallery.

refreshMedia.refresh(path); // Refresh the image gallery
