Question

I have a button which stores whatever text is written in the text form above it when clicked. However, the application force closes when the button is clicked. What could be the problem?

save.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        String FILEOUTPUT = Day;
        BufferedWriter bfw;

        try {
            bfw = new BufferedWriter (new FileWriter(FILEOUTPUT));
            Scanner scan = new Scanner((File) editData.getText());

            bfw.write(scan.nextLine());
            bfw.close();
            Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT);
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(), "Save error", Toast.LENGTH_SHORT);  
        }
    }
});

It’s best to first look at the reported Exception from DDMS in these cases. Can you provide the reported exception from DDMS?
Where is editData? Is it an EditText or a TextView ? You are casting a String to a File directly in that line, instead you should be creating a File object.

should be like:

Scanner scan = new Scanner(new File(editData.getText()));
