Solution 1:

Updated code that solve the problem

public void writeNotesToFile(Context c)
{
    SharedPreferences preferencesWrite  = c.getSharedPreferences("myPreferences", 0);
    SharedPreferences.Editor editor  = preferencesWrite.edit(); 

    // write notes count into the  register
    editor.putInt("notesCount", m_noteCount);
    editor.commit();

    // write notes  to the  file
    SimpleDateFormat sdFormater = new SimpleDateFormat("dd-MMM-yyyy", Locale.US);
    File file = c.getFileStreamPath("Notes");

    if (m_noteCount > 0)
    {
        if(!file.exists())
        {
            try 
            {
                file.createNewFile();
            } 
            catch (Exception e) 
            {

            FileOutputStream fos = new FileOutputStream(file);
            Writer writer = new OutputStreamWriter(fos, "UTF8");

               // FileOutputStream  writer = c.openFileOutput("Notes", Context.MODE_PRIVATE);

            for (int i = 0; i < m_noteCount; i++)
            {
                String noteDate = sdFormater.format(m_arrNoteDate[i]);
                writer.write(noteDate);
