Кто-нибудь предлагает образец для загрузки видео с SD-карты на удаленный сервер?
Загружать видео с Android на сервер?

Имел тот же самый вопрос некоторое время назад. Вот код.
public static int upLoad2Server(String sourceFileUri) {
String upLoadServerUri = "your remote server link";
// String [] string = sourceFileUri;
String fileName = sourceFileUri;
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
String responseFromServer = "";
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
Log.e("Huzza", "Source File Does not exist");
return 0;
}
try { // open a URL connection to the Servlet
FileInputStream fileInputStream = new FileInputStream(sourceFile);
URL url = new URL(upLoadServerUri);
conn = (HttpURLConnection) url.openConnection(); // Open a HTTP connection to the URL
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available(); // create a buffer of maximum size
Log.i("Huzza", "Initial .available : " + bytesAvailable);
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();
Log.i("Upload file to server", "HTTP Response is : " + serverResponseMessage + ": " + serverResponseCode);
// close streams
Log.i("Upload file to server", fileName + " File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
ex.printStackTrace();
Log.e("Upload file to server", "error: " + ex.getMessage(), ex);
} catch (Exception e) {
e.printStackTrace();
}
//this block will give the response of upload link
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
Log.i("Huzza", "RES Message: " + line);
}
rd.close();
} catch (IOException ioex) {
Log.e("Huzza", "error: " + ioex.getMessage(), ioex);
}
return serverResponseCode; // like 200 (Ok)
} // end upLoad2Server
2) назовите его
int reponse=upLoad2Server(""+filepath);

Двухэтапное решение:
1) Выберите видеофайл из галереи.
Создайте глобальный int private static final int SELECT_VIDEO = 3; - не имеет значения, какое число вы используете, если только это вы проверяете позже. Затем используйте намерение выбрать видео.
Intent intent = new Intent();
intent.setType("video/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select a Video "), SELECT_VIDEO);
Используйте onActivityResult(), чтобы запустить метод uploadVideo().
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_VIDEO)
{
System.out.println("SELECT_VIDEO");
Uri selectedImageUri = data.getData();
selectedPath = getPath(selectedImageUri);
System.out.println("SELECT_VIDEO Path : " + selectedPath);
uploadVideo(selectedPath);
}
2) Перейдите в http://hc.apache.org/downloads.cgi, загрузите последнюю банку HttpClient, добавьте ее в свой проект и загрузите видео, используя следующий метод
private void uploadVideo(String videoPath) throws ParseException, IOException {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(YOUR_URL);
FileBody filebodyVideo = new FileBody(new File(videoPath));
StringBody title = new StringBody("Filename: " + videoPath);
StringBody description = new StringBody("This is a video of the agent");
StringBody code = new StringBody(realtorCodeStr);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("videoFile", filebodyVideo);
reqEntity.addPart("title", title);
reqEntity.addPart("description", description);
reqEntity.addPart("code", code);
httppost.setEntity(reqEntity);
// DEBUG
System.out.println( "executing request " + httppost.getRequestLine( ) );
HttpResponse response = httpclient.execute( httppost );
HttpEntity resEntity = response.getEntity( );
// DEBUG
System.out.println( response.getStatusLine( ) );
if (resEntity != null) {
System.out.println( EntityUtils.toString( resEntity ) );
} // end if
if (resEntity != null) {
resEntity.consumeContent( );
} // end if
httpclient.getConnectionManager( ).shutdown( );
} // end of uploadVideo( )
Как только вы его заработаете, вы, вероятно, захотите поместить его в поток и добавить диалог загрузки, но это поможет вам начать работу. Работаю для меня после того, как я безуспешно попробовал метод upload2Server(). Это также будет работать для изображений и аудио с некоторой незначительной настройкой.

Это глобальные переменные, которые нужно определить первым:
private String mString;
private Uri image_uri;
private String response;
private HttpURLConnection conn = null;
private DataOutputStream dos = null;
private String lineEnd = "\r\n";
private String twoHyphens = "--";
private String boundary = "*****";
private int bytesRead, bytesAvailable, bufferSize;
private byte[] buffer;
private String url_for_image_upload = "your_web_api_put_here";
private int maxBufferSize = 1 * 1024 * 1024;
//затем вызовите эти два метода на кнопке onclick() method
mString = getRealPathFromURI(image_uri);
ImageUpload();
//и напишем эти методы следующим образом
private void ImageUpload() {
Toast.makeText(getApplicationContext(),
"Please Wait while uploading Image", Toast.LENGTH_SHORT).show();
try {
FileInputStream fileInputStream = new FileInputStream(new File(mString));
URL url = new URL(url_for_image_upload);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"img_name\";filename=\"img_name"
+ "\"" + lineEnd);
dos.writeBytes(lineEnd);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
BufferedReader in = new BufferedReader(new InputStreamReader(
conn.getInputStream()));
Log.d("BuffrerReader", "" + in);
if (in != null) {
response = convertStreamToString(in);
Log.e("FINAL_RESPONSE-LENGTH",""+response.length());
Log.e("FINAL_RESPONSE", response);
}
fileInputStream.close();
dos.flush();
dos.close();
if (response.startsWith("0")) {
Toast.makeText(getApplicationContext(),
"Image Uploaded not successfully", Toast.LENGTH_SHORT)
.show();
} else {

}
} catch (MalformedURLException ex) {

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