    HttpURLConnection conn;
    URL url = new URL(mServerUrl);
    conn = (HttpURLConnection) url.openConnection();

    conn.setUseCaches(false);
    conn.setRequestMethod("POST");
    conn.setRequestProperty("Content-Type", file.getContentType());
    conn.setRequestProperty("Connection", "close");
    conn.setRequestProperty("Charset", "UTF-8");
    conn.connect();
    DataOutputStream os = new DataOutputStream(conn.getOutputStream());

    int totalSize = 0;
    byte[] buffer = new byte[1024];
    int len = 0;
    while ((len = file.getInStream().read(buffer, 0, 1024)) != -1) {

        totalSize += len;
        WDLog.i("totalSize = " + totalSize);
        os.write(buffer, 0, len);

    }

    file.getInStream().close();
    os.flush();
    os.close();

Upload the file to the server in chunk by chunk basis. example. first upload 1024 bytes of data after getting response from server upload the next 1024 bytes of data and so on until the all the data of the file is uploaded.

I solve the question like this: in while Cycle add if (totalSize > 5* 1024 * 1024) break out and do ( os.flush(); os.close();conn.disconnect(); System.gc();) don't close the file inputstream. and if unfinish redo upload function.

If you testing this code on emulator, make sure that your RAM size close to real device value.
