Pause / Summary HTTP connection download

Question

I want to be able to open an http connection with this file in Android and start downloading it. I should also be able to pause the download at some point and resume it later. How is this achieved in Android? I do not want to start the download again and again.

Such a loader is published here :

HttpURLConnection connection = (HttpURLConnection) url.openConnection(); if(ISSUE_DOWNLOAD_STATUS.intValue()==ECMConstant.ECM_DOWNLOADING){ File file=new File(DESTINATION_PATH); if(file.exists()){ downloaded = (int) file.length(); connection.setRequestProperty("Range", "bytes="+(file.length())+"-"); } }else{ connection.setRequestProperty("Range", "bytes=" + downloaded + "-"); } connection.setDoInput(true); connection.setDoOutput(true); progressBar.setMax(connection.getContentLength()); in = new BufferedInputStream(connection.getInputStream()); fos=(downloaded==0)? new FileOutputStream(DESTINATION_PATH): new FileOutputStream(DESTINATION_PATH,true); bout = new BufferedOutputStream(fos, 1024); byte[] data = new byte[1024]; int x = 0; while ((x = in.read(data, 0, 1024)) >= 0) { bout.write(data, 0, x); downloaded += x; progressBar.setProgress(downloaded); }
