where to find my android new internal file

Question

I am trying to save a string input from the user (called editServer) into a internal file with:

button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // Perform action on click
                EditText server = (EditText) findViewById(R.id.editServer);
                Log.i("Settings", server.getText().toString());

                String filename = "ServerURL.txt";
                String serverurl = server.getText().toString();
                FileOutputStream outputStream;

                try {
                    outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
                    outputStream.write(serverurl.getBytes());
                    Log.i("Write",serverurl+" saved to "+filename);
                    outputStream.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }

            }
            });

My issue is that after that I can't find this file. Where is it? I tried opening the Android Device Monitor with Android Studio but I can't find the folder. I tried to get the string using:

        fis = context.openFileInput("ServerURL.txt");
        InputStreamReader isr = new InputStreamReader(fis);
        BufferedReader bufferedReader = new BufferedReader(isr);
        StringBuilder sb = new StringBuilder();
            while ((line = bufferedReader.readLine()) != null) {
                sb.append(line);
            }
        return line;

But it returns null, which makes me believe that I am making a mistake. Am I creating the file properly or is there some issue in my code?

Thank you.

Update

Android device monitor -> File explorer will let you see and find where your file is.

Answer 1

You probably want to return sb.toString() instead of line.
