Found reliance on default encoding: new java.io.FileWriter(File, boolean)

Question

I'm using FileWrite class to write into a file.and its working fine. But FindBugs is pointing me a Minor issue in my code snippet.

code snippet:

  SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";
        FileWriter writer = null;
        try {
            File root = new File(Environment.getExternalStorageDirectory(), "Test");
            if (!root.exists()) {
                root.mkdirs();
            }
            File gpxfile = new File(root, fileName);

            writer = new FileWriter(gpxfile, true);
            writer.append(text + "\n\n");

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

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

Findbug Report:

In which line i'm getting this Error?

  writer = new FileWriter(gpxfile, true);

Could some one please brief me what is this exactly? And how can we solve this?

Answer 1

Resolved this Issue by replacing

FileWriter writer = new FileWriter(gpxfile, true);

with

  FileOutputStream fileStream = new FileOutputStream(gpxfile);
            writer = new OutputStreamWriter(fileStream, "UTF-8");
