For those who struggle to fix that code here is the fixed one

ab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
                intent.setType("*/*");
                startActivityForResult(intent, PICKFILE_RESULT_CODE);
            }
        });

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == PICKFILE_RESULT_CODE) {
            Uri uri = data.getData();
            LaterFunction(uri);
        }
    }

public void LaterFunction(Uri uri) {
        BufferedReader br;
        FileOutputStream os;
        try {
            br = new BufferedReader(new InputStreamReader(getContentResolver().openInputStream(uri)));
            //WHAT TODO ? Is this creates new file with
            //the name NewFileName on internal app storage?
            os = openFileOutput("newFileName", Context.MODE_PRIVATE);
            String line = null;
            while ((line = br.readLine()) != null) {
                os.write(line.getBytes());
                Log.w("nlllllllllllll",line);
            }
            br.close();
            os.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

Answer 2

Step #1: Delete String filePathName = "WHAT TODO ?";

Step #2: Change LaterFunction(filePathName); to LaterFunction(uri);

Step #3: Change br = new BufferedReader(new FileReader("WHAT TODO ?")); to br = new BufferedReader(new InputStreamReader(getContentResolver().openInputStream(uri));

That is the minimum necessary to address your question.

However, a MIME type of */* will match any type of file, not just text files. Binary files should not be copied using readLine(). If you only want plain text files, use text/plain instead of */*.
