我正在录制视频并按下按钮将其上传到服务器。 同时我需要更新我的数据库中的一个表，该表有2列，名为＆＃34; userId和filename＆＃34;。
我跟踪tutorial上传视频，现在我需要将UserId传递给php页面。我不知道该怎么做。
我发现了这个Answer，但是它给出了IOException - stream closed
代码段：

byte[] buffer;
int maxBufferSize = 1024 * 1024;
sourceFileUri = sourceFileUri.replace("file:///","/");
File sourceFile = new File(sourceFileUri);
Log.e("Image--sourceFile",""+sourceFile);
Log.e("Image--sourceFileUri", "" + sourceFileUri);
if (!sourceFile.isFile())
{
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :" + fileUri);
runOnUiThread(new Runnable() {
