Php 如何利用安卓毕加索在服务器的非公开html位置加载图像？

在安卓应用程序中，要加载毕加索的图像，需要图像的URL，但我想将图像放在服务器的非公共html位置，那里没有可用的URL

通信代码如下：

public SendJSONToServer(Context context,String FileNewName,String url,String uri, SendJSONToServer.OnEventListener callback ) {
        this.url = url;
        this.uri = uri;
        this.FileNewName = FileNewName;
        mCallBack = callback;
        mContext = context;
    }

    @Override
    protected void onPreExecute() {

        super.onPreExecute();

    }

    @Override
    protected String doInBackground(String... params) {

        if (checkNetworkConnection() == false)
            return  null;
        try {

            JSONHttpHandler3 sh = new JSONHttpHandler3();
            String srv_RC ;
            srv_RC = sh.makeServiceCall3(FileNewName,url,uri);

            if (srv_RC.equals("Move To Server Failed"))
            {
                return null;
            }
            else if (srv_RC.equals("Move To Server successful"))
            {
                return "Move To Server successful";
            }
            else
            {
                return srv_RC;
            }

        }
        catch (Exception e)
        {
            mException = e;
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        if (mCallBack != null) {
            if (mException == null) {

                if(result == null)
                {
                    mCallBack.onFailure(null);
                }
                else
                {
                   mCallBack.onSuccess(result);
                }
            } else {
                mCallBack.onFailure(null);
            }
        }
    }

    public interface OnEventListener<T> {
        public void onSuccess(T object);
        public void onFailure(String f);
    }

    public boolean checkNetworkConnection() {
        ConnectivityManager connMgr = (ConnectivityManager)
                mContext.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
        boolean isConnected = false;
        if (networkInfo != null && (isConnected = networkInfo.isConnected())) {

        } 
        else {

        }
        return isConnected;
    }  

对于PHP代码的文件访问，以下代码是处理文件的示例（这是JSON示例，但也可以是图像）：

您能为我提供帮助链接或示例代码吗？
