Save file in Android with spaces in file name

Question

I need for my android application to save an xml file into the external cache with a file name which contains space.

DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(activity
                    .getExternalCacheDir().getAbsolutePath()
                    + "/Local storage.xml"));

transformer.transform(source, result);

When I browse manually into my file directory I find this file : "Local%20storage.xml".

So after when I try to read it with

File localStorageXmlFile = new File(activity.getExternalCacheDir()
                .getAbsolutePath()
                + "/Local storage.xml");

But I have a FileNotFoundException because the file "Local storage.xml" can't be found on my device.

Any ideas to solve this? Seb

It was hard to identify the source of this problem but it comes from StreamResult which replaces spaces in file name by %20. There is a bug report for this issue here.

And here is the solution :

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);

FileOutputStream fos = null;
try {
    fos = new FileOutputStream(new File(activity
                .getExternalCacheDir().getAbsolutePath()
                + "/" + "Local storage" + ".xml"));
    Result fileResult = new StreamResult(fos);
    transformer.transform(source, fileResult);
} catch (FileNotFoundException e) {
    e.printStackTrace();
} finally {
    if (fos != null) {
        fos.close();
    }
}

Thanks again to both of you for trying to solve my issue.
