请问下面的代码为什么在android上会失败?

String strFileName = "test.jpg";
    String strBucket = "XXXX";

    Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY);
    String token = auth.uploadToken(strBucket, strFileName);

    UploadManager uploadManager = new UploadManager();

    File data = new File(
            "/storage/emulated/0/DCIM/Camera/20150910_111426.jpg");// =
    if (!data.isFile()) {
        return;
    }

    String key = strFileName;// <指定七牛服务上的文件名，或 null>;

    uploadManager.put(data, key, token, new UpCompletionHandler() {
        @Override
        public void complete(String key, ResponseInfo responseInfo,
                JSONObject response) {
            if (responseInfo.statusCode == 200) {
                Toast.makeText(getApplication(), "完成上传", 0).show();
            } else {
                Toast.makeText(getApplication(), "上传失败", 0).show();
            }
        }
    }, null);

空间地址必须是在七牛新建的空间地址名称，必须一样才可以， 七牛token 最好在服务器端生成
