안드로이드 앱에서 http 서버로 비디오 업로드하기

Question

안드로이드 장치에서 http 서버로 비디오 파일을 업로드하려고합니다. 그리고 다중 파일 업로드를 사용했습니다. 코드가 오디오 파일과 함께 사용되면 올바르게 작동합니다. 그러나 비디오 파일을 업로드하려고하면 HttpHostConnectException이 발생합니다. 앱에 필요한 모든 권한을 추가했습니다.

HttpClient httpClient = new DefaultHttpClient(); 
      HttpPost postRequest=new HttpPost("http://xxx.xxx.x.xxx:8090/WebAppTest/rest/file/upload?name=five.mp4"); 

      MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 
      FileBody fb = new FileBody(filename, "video/3gpp"); 
      FormBodyPart bodyPart = new FormBodyPart("file",fb); 
       reqEntity.addPart(bodyPart); 
      postRequest.setEntity(reqEntity); 
      HttpResponse response=httpClient.execute(postRequest);

을 사용하여 파일 업로드를위한이 클래스를 BigFileUpload. 비디오 업로드에 사용합니다.

작동하지 않습니다.
