            // Toast.LENGTH_LONG).show();

        } catch (IOException ioex) {
            Log.e("Error: ", "error: " + ioex.getMessage(), ioex);
        }
        try {
            fileInputStream.close();

    } catch (MalformedURLException ex) {
        Log.e("Error:", "error: " + ex.getMessage(), ex);
    }

    catch (IOException ioe) {
        Log.e("Error:", "error: " + ioe.getMessage(), ioe);
    }

}

我有这段代码可以将 fie 上传到服务器，但是我无法上传大小超过 8MB 的文件；它给出了 FileNotFoundException 异常，即找不到 SERVER_URL+"/uploadpic2.php"。请任何机构帮助我解决此错误。谢谢。

根据此网页，您需要更改 php 配置文件中的设置。

限制在那里执行

post_max_size = 16M
upload_max_filesize = 16M

我也认为这条线

String urlString = "SERVER_URL+"/uploadpic2.php";

应该读

String urlString = SERVER_URL + "/uploadpic2.php";

更新

我发现了另一个与你类似的问题。根据那个问题，这看起来像是 phoneGap 的问题。
