Question

I am uploading a stream to server.But my Input-stream contain a big video file.So i want to split it in different Input-stream and then i will send them one by one.

I have gone through a question that TeeOutputStream(i do not how it work in java) in Java for doing this.But it does not exist in android.
Any help much appreciated as usual

Updated

Please donot suggest me manual way.

Answer 1

You do not have to split up the input or output stream.
You can upload a large file with multipart entity.In Multipart entity there is a class FileEntity which is responsible to upload a file

I have a code for multipart entity see below code.

public class uploadFile extends AsyncTask<Void, Void, Boolean> {
        private final ProgressDialog dialog = new ProgressDialog(parentActivity);

        protected void onPreExecute() {
            this.dialog.setMessage("Uploading file");
            this.dialog.setCancelable(false);
            this.dialog.show();
        }

        @Override
        protected Boolean doInBackground(Void... arg0) {

            try {
                HttpClient httpClient = new DefaultHttpClient();
                HttpPost postRequest = new HttpPost(URLS.PRESCRIPTION_POST_URL);
                MultipartEntity reqEntity = new MultipartEntity(
                        HttpMultipartMode.BROWSER_COMPATIBLE);

                reqEntity.addPart("title", new StringBody("This is a title of video file"));
                try {
                    File f = new File(Environment.getExternalStorageDirectory(), "your file name with extension");

                    FileBody body = new FileBody(f);
                    reqEntity.addPart("parameter that server will read", body);

                } catch (Exception e) {
                    reqEntity.addPart("parameter that server will read", new StringBody(""));
                }

                reqEntity.addPart("description", new StringBody("description"));

                postRequest.setEntity(reqEntity);
                HttpResponse response = httpClient.execute(postRequest);

                BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8")); 
                String sResponse; StringBuilder s = new StringBuilder(); 
                while ((sResponse = reader.readLine()) != null) { 
                    s = s.append(sResponse); 
                } 
                Log.v("Response for POst", s.toString());
                return true;
            } catch (Exception e) {
                Log.e("MyPharmacyOptions", "Error :: " + e);
            }
            return false;
        }

        @Override
        protected void onPostExecute(Boolean result) {
            if (this.dialog.isShowing()) {
                this.dialog.dismiss();
            }
            if (result) {
                Toast.makeText(parentActivity,
                        "File uploaded successfully", Toast.LENGTH_LONG)
                        .show();

            } else {
                Toast.makeText(parentActivity, "Your Request not complete",
                        Toast.LENGTH_LONG).show();
            }
        }
    }

To use MultipartEntity you will required a jar file httpmime-4.1.2.jar.

There is also another alternative of this

HttpURLConnection connection = null;
DataOutputStream outputStream = null;
DataInputStream inputStream = null;

String pathToOurFile = "/sdcard/file_to_send.mp3"; //complete path of file from your android device
String urlServer = "URL of your server";// complete path of server
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary =  "*****";

try
{
FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

URL url = new URL(urlServer);
connection = (HttpURLConnection) url.openConnection();

// Allow Inputs & Outputs
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);

// Enable POST method
connection.setRequestMethod("POST");

connection.setRequestProperty("Connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);

outputStream = new DataOutputStream( connection.getOutputStream() );
outputStream.writeBytes(twoHyphens + boundary + lineEnd);
outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd);
outputStream.writeBytes(lineEnd);

bytesAvailable = fileInputStream.available();

byte []buffer = new byte[4096];
int read = 0;
while ( (read = fileInputStream.read(buffer)) != -1 ) {
    outputStream.write(buffer, 0, read);
}

outputStream.writeBytes(lineEnd);
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// Responses from the server (code and message)
serverResponseCode = connection.getResponseCode();
serverResponseMessage = connection.getResponseMessage();

fileInputStream.close();
outputStream.flush();
outputStream.close();
}
catch (Exception ex)
{
//Exception handling
}
