Upload large file in Android without outofmemory error

Did you try using

con.setChunkedStreamingMode(1024);

This will help you to chunk your data into specific size, so that you need not keep your entire file in the memory.

UPDATE:

Try using the below method. I use this method to upload a 80 mb file without Exception.

public String sendFileToServer(String filename, String targetUrl) {    String response = "error";    Log.e("Image filename", filename);    Log.e("url", targetUrl);    HttpURLConnection connection = null;    DataOutputStream outputStream = null;    // DataInputStream inputStream = null;    String pathToOurFile = filename;    String urlServer = targetUrl;    String lineEnd = "\r\n";    String twoHyphens = "--";    String boundary = "*****";    DateFormat df = new SimpleDateFormat("yyyy_MM_dd_HH:mm:ss");    int bytesRead, bytesAvailable, bufferSize;    byte[] buffer;    int maxBufferSize = 1 * 1024;    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);        connection.setChunkedStreamingMode(1024);        // 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);        String connstr = null;        connstr = "Content-Disposition: form-data; name=\"uploadedfile\";filename=\""                + pathToOurFile + "\"" + lineEnd;        Log.i("Connstr", connstr);        outputStream.writeBytes(connstr);        outputStream.writeBytes(lineEnd);        bytesAvailable = fileInputStream.available();        bufferSize = Math.min(bytesAvailable, maxBufferSize);        buffer = new byte[bufferSize];        // Read file        bytesRead = fileInputStream.read(buffer, 0, bufferSize);        Log.e("Image length", bytesAvailable + "");        try {            while (bytesRead > 0) {                try {                    outputStream.write(buffer, 0, bufferSize);                } catch (OutOfMemoryError e) {                    e.printStackTrace();                    response = "outofmemoryerror";                    return response;                }                bytesAvailable = fileInputStream.available();                bufferSize = Math.min(bytesAvailable, maxBufferSize);                bytesRead = fileInputStream.read(buffer, 0, bufferSize);            }        } catch (Exception e) {            e.printStackTrace();            response = "error";            return response;        }        outputStream.writeBytes(lineEnd);        outputStream.writeBytes(twoHyphens + boundary + twoHyphens                + lineEnd);        // Responses from the server (code and message)        int serverResponseCode = connection.getResponseCode();        String serverResponseMessage = connection.getResponseMessage();        Log.i("Server Response Code ", "" + serverResponseCode);        Log.i("Server Response Message", serverResponseMessage);        if (serverResponseCode == 200) {            response = "true";        }        String CDate = null;        Date serverTime = new Date(connection.getDate());        try {            CDate = df.format(serverTime);        } catch (Exception e) {            e.printStackTrace();            Log.e("Date Exception", e.getMessage() + " Parse Exception");        }        Log.i("Server Response Time", CDate + "");        filename = CDate                + filename.substring(filename.lastIndexOf("."),                        filename.length());        Log.i("File Name in Server : ", filename);        fileInputStream.close();        outputStream.flush();        outputStream.close();        outputStream = null;    } catch (Exception ex) {        // Exception handling        response = "error";        Log.e("Send file Exception", ex.getMessage() + "");        ex.printStackTrace();    }    return response;}

if Server accept chunked mode, you can use

((HttpURLConnection) con).setChunkedStreamingMode(chunkLength)

otherwise you can use

((HttpURLConnection) con).setChunkedStreamingMode(0);

or

/* compute first your request content length   contentLength = formBodyLength + yourFileSize*/con.setRequestProperty("Content-Length", String.valueOf(contentLength));((HttpURLConnection) con).setFixedLengthStreamingMode(contentLength);

finally... send what you want

bitmap=Bitmap.createScaledBitmap(bitmap, 100, 100, true);ByteArrayOutputStream stream = new ByteArrayOutputStream();bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); //compress to format you want.byte [] byte_arr = stream.toByteArray();  String image_str = Base64.encodeBytes(byte_arr);

Best Way I tried it was successful for me!!!
