Reading a txt file into an ArrayList Android

Bats :

I am trying to read a file into an Array. The following code saves the file (I know it needs a clean up)

    public void save() {
        String text = Subreddit_Array_List.toString() + "\n";
        FileOutputStream fos = null;
        deleteFile("example.txt");
        try {
            try {
                fos = openFileOutput(FILENAME, MODE_APPEND);
                try {
                    fos.write (text.getBytes());
                } catch (IOException ex) {
                    ex.printStackTrace();
                }
            } catch (FileNotFoundException ex) {
                ex.printStackTrace();
            }
        } finally {
            if (fos != null) {
                try {
                    try {
                        fos.close();
                    } catch (IOException e) {
                        e.printStackTrace();

                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }

The input file looks like this:

[Test, Cats]

So either I have to try and save without the commas and per line or I need a way of separating the values from the commas. Any help would be much appreciated.

My Current Load code:

    public void load() {
        FileInputStream fis = null;

        try {
            fis = openFileInput(FILENAME);
            InputStreamReader isr = new InputStreamReader(fis);
            BufferedReader br = new BufferedReader(isr);
            StringBuilder sb = new StringBuilder();
            String text;


            while ((text = br.readLine()) != null) {
                sb.append(text).append("\n");
                Subreddit_Array_List.add(text);
            }

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (fis != null) {
                try {
                    fis.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

snachmsm :

maybe splitting by coma will be sufficient?

List<String> customList = Arrays.asList(text.split(","));

note it will leave brackets [] on start and end of first and last list item, and also white space on start (as coma is always followed by space), so you need to clean up a bit using trim and replace methods (or maybe split by , and substring text removing first and last char if you are shure these will be brackets always)

edit: put my line in here

    try {
        fis = openFileInput(FILENAME);
        InputStreamReader isr = new InputStreamReader(fis);
        BufferedReader br = new BufferedReader(isr);
        StringBuilder sb = new StringBuilder();
        String text;

        while ((text = br.readLine()) != null) {
            sb.append(text).append("\n");
        }

        text = sb.toString();
        // below line removes first and last character (brackets)
        text = text.substring(1, text.length() - 1);
        // text variable contains an array, split it by coma and space
        List<String> customList = text.length() == 0 ? 
            new ArrayList<String>() : Arrays.asList(text.split(Pattern.quote(", ")));

        Subreddit_Array_List.addAll(customList);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }

note that customList will contain two Strings: Test and Cats
