Как сделать функцию дозагрузки файла

Скачиваю файл таким образом:

Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    trustAllHosts();
                    URL url = new URL(downloadUrl);//Create Download URl
                    HttpsURLConnection c = (HttpsURLConnection) url.openConnection();//Open Url Connection
                    //c.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
                    //c.setInstanceFollowRedirects(true);
                    c.setRequestMethod("GET");//Set Request Method to "GET" since we are grtting data
                    c.connect();//connect the URL Connection
                    //If Connection response is not OK then show Logs
                    if (c.getResponseCode() != HttpsURLConnection.HTTP_OK) {
                        Log.e(Constants.LOG_TAG, "Server returned HTTP " + c.getResponseCode() + " " + c.getResponseMessage());
                        return;
                    }
                    int fileSize = c.getContentLength();
                    int downloadSize = 0;
                    //If File is not present create directory
                    if (!toPath.exists()) {
                        toPath.mkdir();
                        Log.e(Constants.LOG_TAG, "Directory Created.");
                    }
                    File outputFile = new File(toPath, toFileName);//Create Output file in Main File
                    //Create New File if not present
                    if (!outputFile.exists()) {
                        if (outputFile.createNewFile())
                            Log.e(Constants.LOG_TAG, "File Created ");
                        else
                            Log.e(Constants.LOG_TAG, "File no Created ");
                    }
                    FileOutputStream fos = new FileOutputStream(outputFile);//Get OutputStream for NewFile Location
                    InputStream is = c.getInputStream();//Get InputStream for connection
                    byte[] buffer = new byte[1024];//Set buffer type
                    int len1 = 0;//init length
                    while ((len1 = is.read(buffer)) != -1) {
                        if (Thread.currentThread().isInterrupted()){
                            Log.d(Constants.LOG_TAG, "Загрузка файла прервано- " + outputFile.getPath());
                            fos.close();
                            is.close();
                            return;
                        }
                        fos.write(buffer, 0, len1);//Write new file
                        downloadSize+=len1;
                        int percent = (int) (downloadSize * 100 / fileSize);
                        updateUI(outputFile.getName(), fileSize, downloadSize);
                        Log.d(Constants.LOG_TAG, "Скачано " + percent + "%");
                    }
                    Log.d(Constants.LOG_TAG, "файл скачан " + outputFile.getPath());
                    //Close all connection after doing task
                    fos.close();
                    is.close();
                } catch (Exception e){
                    if (e instanceof InterruptedIOException || e instanceof InterruptedException){
                        if (downloadThreadMap.containsKey(downloadUrl)) {
                            downloadThreadMap.get(downloadUrl).interrupt();
                        }
                    }
                    e.printStackTrace();
                } finally {
                    if (downloadThreadMap.containsKey(downloadUrl)) downloadThreadMap.remove(downloadUrl);
                }
            }
        });
        downloadThreadMap.put(downloadUrl, thread);
        thread.start();

Возможно ли сделать дозагрузку файла например: при экстренной перезагрузки устройства.
