Downloading XML but No such file or directory

Question

I'm rather new to all this, so please forgive me. I'm trying to download an XML file to the device, which can then be parsed. The code I have at the moment is -

public class DownloadFromURL implements Runnable {
    private static final int BUFFER_SIZE = 4096;

    @Override
    public void run() {
        Log.i("Download From URL", "Run");

        String fileURL = "http://m.highways.gov.uk/feeds/rss/AllEvents.xml";
        String saveDir = "/data/data/com.androidandyuk/files";
        URL url;
        try {
            url = new URL(fileURL);

            HttpURLConnection httpConn = (HttpURLConnection) 
            url.openConnection();

            int responseCode = httpConn.getResponseCode();
            Log.i("Download from URL", "Resp Code :" + responseCode);
            // always check HTTP response code first
            if (responseCode == HttpURLConnection.HTTP_OK) {
                String fileName = "";
                String disposition = httpConn.getHeaderField("Content-Disposition");
                String contentType = httpConn.getContentType();
                int contentLength = httpConn.getContentLength();

                if (disposition != null) {
                    // extracts file name from header field
                    int index = disposition.indexOf("filename=");
                    if (index > 0) {
                        fileName = disposition.substring(index + 10,
                                disposition.length() - 1);
                    }
                } else {
                    // extracts file name from URL
                    fileName = fileURL.substring(fileURL.lastIndexOf("/") + 1,
                            fileURL.length());
                }

                // opens input stream from the HTTP connection
                InputStream inputStream = httpConn.getInputStream();
                String saveFilePath = saveDir + File.separator + fileName;
                Log.i("Download from URL", "Opening a Stream");
                // opens an output stream to save into file
                FileOutputStream outputStream = new 
                FileOutputStream(saveFilePath);

                int bytesRead = -1;
                byte[] buffer = new byte[BUFFER_SIZE];
                while ((bytesRead = inputStream.read(buffer)) != -1) {
                    outputStream.write(buffer, 0, bytesRead);
                }

                outputStream.close();
                inputStream.close();

                Log.i("Download", "File downloaded");
            } else {
                Log.i("Download", "No file to download. Server replied HTTP code: " + responseCode);
            }

            httpConn.disconnect();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Which is then run by -

DownloadFromURL getTraffic = new DownloadFromURL();
            Thread t = new Thread(getTraffic);
            t.start();

But as it runs, I get an error saying 'java.io.FileNotFoundException: /data/data/com.androidandyuk/files/AllEvents.xml (No such file or directory)'

Can anyone please help?

(And if you want to downvote me, please at least comment why, as I get downvoted even when I feel I've formatted my question well... and done lots of searching for the answer already! Thanks)

try to use `saveDir.mkdirs();` and then `new File(saveFilePath).createFile()` and then write it. — SRB Bans, May 18 '17 at 11:09
Thanks. Should that read 'use' saveDir.dkdirs();? I get cannot resolve method dkdirs() error in Android Studio? — AndyCr15, May 18 '17 at 11:15
@sasikumar Using that code gives me the same error. 'No such file or directory' — AndyCr15, May 18 '17 at 11:19
@AndyCr15 updated my comment.. its `mkdirs()` to make directories if not exists,, then create a file and write the input stream there. — SRB Bans, May 18 '17 at 11:19
@SRBbans thanks, but I get the same message about not resolving the method? saveDir is a String. From what I see about mkdirs() I use it on a file? — AndyCr15, May 18 '17 at 11:22
Thats because `saveDir` is a `String` and not a `File`. But do you really want to hard code the path to the files directory? Why not use `Context.getDir()`? — Henry, May 18 '17 at 11:27
