Ayuda :(¿Alguien sabe cómo escribir una solicitud POST para cargar los vídeos de Youtube a través de la API de Youtube, en Java?Youtube POST de carga en Java
La estructura de la solicitud POST requerida se describe here.
Desafortunadamente no puedo usar las bibliotecas de cliente de Youtube Java, porque estoy trabajando en Android, que no las admite.
Tengo un código intentado a continuación, pero no funciona (obtengo el error que conn.getResponseCode() es nulo).
public void videoUpload() {
HttpURLConnection conn = null;
// BufferedReader br = null;
DataOutputStream dos = null;
InputStream inStream = null;
// InputStream is = null;
// OutputStream os = null;
// boolean ret = false;
// String StrMessage = "";
//file path
// get filename from videoURI
String path = "file:///sdcard/";
String existingFileName = "video.3gp";
File videoFile = new File(path + existingFileName);
// String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "b93dcbA3";
String ver = "2";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1024;
// String responseFromServer = "";
try {
FileInputStream fileInputStream = new FileInputStream(videoFile);
URL url = new URL("http://uploads.gdata.youtube.com/feeds/api/users/[XXXXXXXXXX]/uploads");
conn = (HttpURLConnection) url.openConnection();
// Allow Inputs
conn.setDoInput(true);
// Allow Outputs
conn.setDoOutput(true);
// Don't use a cached copy.
conn.setUseCaches(false);
// Use a post method.
conn.setRequestMethod("POST");
// conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Host", "uploads.gdata.youtube.com");
conn.setRequestProperty("Authorization", "GoogleLogin auth=" + token);
conn.setRequestProperty("GData-Version", ver);
conn.setRequestProperty("X-Gdata-Client", clientId);

"multipart/related;boundary=" + boundary);
conn.setRequestProperty("Content-Length", new Long(videoFile //and this
.length()).toString());
conn.setRequestProperty("Connection", "close");
//do we not want a boundary string here?
conn.setRequestProperty("Content-Type",
"application/atom+xml; charset=UTF-8");
//and here?
