java.io.FileNotFoundException on Android, open failed: ENOENT (No such file or directory)

Question

I'm trying to save and write an XML file with some data for my app, but when it tries to open the file it gives an java.io.FileNotFoundException.

the code i'm using to save the XML file is:

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount",   "2");
DOMSource source = new DOMSource(doc);

StreamResult result = new StreamResult(new File(getActivity().getFilesDir(),  "rooster.xml"));
System.out.println("test");

The code I'm using to read the file is:

        File XmlFile = new File(getActivity().getFilesDir(), "file.xml");
        if (!XmlFile.exists()){
            System.out.println("No XML file!");
        }
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(XmlFile);

The logcat it gives is:

Does someone know how to solve this problem? Thanks in advance

The whole read code is:

public String[] getRooster() throws Exception {
String[] dagen;
dagen = new String[5];
dagen[0] = "maandag";
dagen[1] = "dinsdag";
dagen[2] = "woensdag";
dagen[3] = "donderdag";
dagen[4] = "vrijdag";
int aantDagen = dagen.length;

// bepaal de dag van de week
Calendar c = Calendar.getInstance();
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK)-2;
File XmlFile = new File(getActivity().getFilesDir(), "file.xml");
if (!XmlFile.exists()){
    System.out.println("No XML file!");
}
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(XmlFile);

doc.getDocumentElement().normalize();

NodeList nList = doc.getElementsByTagName(dagen[dayOfWeek]);
Node nNode = nList.item(0);

String dag = nNode.getNodeName().substring(0,1).toUpperCase() + nNode.getNodeName().substring(1);
Element eElement = (Element) nNode;

String eerste = ("1e : " + eElement.getElementsByTagName("eerste").item(0).getTextContent());
String tweede = ("2e : " + eElement.getElementsByTagName("tweede").item(0).getTextContent());
String derde = ("3e : " + eElement.getElementsByTagName("derde").item(0).getTextContent());
String vierde = ("4e : " + eElement.getElementsByTagName("vierde").item(0).getTextContent());
String vijfde = ("5e : " + eElement.getElementsByTagName("vijfde").item(0).getTextContent());
String zesde = ("6e : " + eElement.getElementsByTagName("zesde").item(0).getTextContent());
String zevende = ("7e : " + eElement.getElementsByTagName("zevende").item(0).getTextContent());
String achtste = ("8e : " + eElement.getElementsByTagName("achste").item(0).getTextContent());
return new String[] {dag, eerste, tweede, derde, vierde, vijfde, zesde, zevende, achtste};

Answer 1

Thanks to greenapps I found my solution. As he said my streamresult wasn't doing anything.

I fixed it by replacing

File XmlFile = new File(getActivity().getFilesDir(), "file.xml");

with

FileInputStream XmlFile = getActivity().openFileInput("file.xml");

and replacing

StreamResult result = new StreamResult(new File(getActivity().getFilesDir(),  "rooster.xml"));

with

StreamResult result = new StreamResult(getActivity().openFileOutput("rooster.xml", getActivity().MODE_PRIVATE));

If you use an emulator, probably you didn't set memory for the emulator device. Go to AVD Manager, choose your device, click "Edit", fill in "Internal Storage".

Also you have to add

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> in manifest.xml
