You can use this code. I am downloading a OTA file as follow:

static class FirmwareDownload extends AsyncTask<String, String, String> {

        public String TAG = "Super LOG";
        public String file;
        int lenghtOfFile;
        long total;

        @Override
        protected String doInBackground(String... f_url) {
            try {
                int count;
                Utilies.getInternet();

                URL url = new URL(f_url[0]);
                URLConnection connection = url.openConnection();
                connection.connect();
                lenghtOfFile = connection.getContentLength();
                mProgressBar.setMax(lenghtOfFile);
                InputStream input = new BufferedInputStream(url.openStream(), 8192);
                String fileName = f_url[0].substring(f_url[0].lastIndexOf("/"), f_url[0].length());
                File root = Environment.getExternalStorageDirectory();
                File dir = new File(root.getAbsolutePath() + fileName);

                Log.d(TAG, "trying to download in : " + dir);
                dir.getAbsolutePath();
                OutputStream output = new FileOutputStream(dir);
                byte data[] = new byte[1024];


                while ((count = input.read(data)) != -1) {

                    if (isCancelled())
                        break;

                    total += count;
                    mProgressBar.setProgress(Integer.parseInt("" + total));
                    Log.d("Downloading " + fileName + " : ", " " + (int) ((total * 100) / lenghtOfFile));
                    mPercentage.post(new Runnable() {
                        @Override
                        public void run() {
                            mPercentage.setText(total / (1024 * 1024) + " Mb / " + lenghtOfFile / (1024 * 1024) + " Mb");
                        }
                    });
                    output.write(data, 0, count);
                }

                output.flush();
                output.close();
                input.close();

                //new InstallHelper().commandLine("mkdir data/data/ota");

                File fDest = new File("/data/data/ota/" + fileName);
                copyFile(dir, fDest);
                FirmwareInstaller fw = new FirmwareInstaller();
                fw.updateFirmware();

            } catch (Exception a) {
                System.out.println("Error trying donwloading firmware " + a);
                new InstallHelper().commandLine("rm -r  data/data/ota");
                dialog.dismiss();

            }
            return null;
        }

    }

So, If you want to cancel, just use this code:

 fDownload.cancel(true);
