我無法調試我的一些代碼。這是一個簡單的便箋應用程序，它試圖將字符串存儲到後臺的文件中。但是，當我在平板電腦上運行應用程序時，我得到確認代碼運行的麪包，但我無法在平板電腦內部存儲器上找到該文件以證明其已存儲？保存到文件Android
我的代碼：
public void onClick(View v) {
//Gets the note detail from the fields.
noteContent = content.getText().toString();
noteTitle = title.getText().toString();
Date date = new Date();
if (noteContent.length() == 0 || noteTitle.length() == 0) {
Toast.makeText(getApplicationContext(), "Please fill in both note title and content before saving",
Toast.LENGTH_LONG).show();
} else {
//Adds the notes together as an object of note.
note createdNote = new note(noteContent, noteTitle);
//Adds the note to the object array.
noteArray.add(createdNote);
//Testing
note test = noteArray.get(0);
String testTitle = test.getTitle();
String testContent = test.getContent();
System.out.println(testTitle);
System.out.println(testContent);
//Concatenating string.
String noteString = testTitle + "-" + testContent;
try {
FileOutputStream FO = openFileOutput(fileName, MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(FO);
try {
System.out.println(noteString);
osw.write(noteString);
osw.flush();
osw.close();
Toast.makeText(getBaseContext(), "NOTE_SAVED", Toast.LENGTH_LONG).show();
} catch(IOException e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
