How to set default ringtone from ringtones programmatically

I am trying to set an mp3 from the raw folder as the phone's ringtone. The ringtone is stored in the ringtones folder and is an option to select, however I would like to have the ringtone selected as default. How can I do this programmatically?

private void setRingtone() {
        AssetFileDescriptor openAssetFileDescriptor;
        ((AudioManager) getActivity().getSystemService(AUDIO_SERVICE)).setRingerMode(2);
        File file = new File(Environment.getExternalStorageDirectory() + "/appkeeda", this.fNmae);
        if (!file.getParentFile().exists()) {
            file.getParentFile().mkdirs();
        }
        if (!file.exists()) {
            try {
                file.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        Uri parse = Uri.parse(this.fPAth);
        ContentResolver contentResolver = getActivity().getContentResolver();
        try {
            openAssetFileDescriptor = contentResolver.openAssetFileDescriptor(parse, "r");
        } catch (FileNotFoundException e2) {
            openAssetFileDescriptor = null;
        }
        try {
            byte[] bArr = new byte[1024];
            FileInputStream createInputStream = openAssetFileDescriptor.createInputStream();
            FileOutputStream fileOutputStream = new FileOutputStream(file);
            for (int read = createInputStream.read(bArr); read != -1; read = createInputStream.read(bArr)) {
                fileOutputStream.write(bArr, 0, read);
            }
            fileOutputStream.close();
        } catch (IOException e3) {
            e3.printStackTrace();
        }
        ContentValues contentValues = new ContentValues();
        contentValues.put("_data", file.getAbsolutePath());
        contentValues.put("title", mp3s[position]);
        contentValues.put("mime_type", "audio/mp3");
        contentValues.put("_size", Long.valueOf(file.length()));
        contentValues.put("artist", Integer.valueOf(R.string.app_name));
        contentValues.put("is_ringtone", Boolean.valueOf(true));
        contentValues.put("is_notification", Boolean.valueOf(false));
        contentValues.put("is_alarm", Boolean.valueOf(false));
        contentValues.put("is_music", Boolean.valueOf(false));
        try {
            //Toast.makeText(this, new StringBuilder().append("Ringtone set successfully"), Toast.LENGTH_LONG).show();
            RingtoneManager.setActualDefaultRingtoneUri(getActivity().getBaseContext(), 1, contentResolver.insert(MediaStore.Audio.Media.getContentUriForPath(file.getAbsolutePath()), contentValues));
        } catch (Throwable th) {
            //Toast.makeText(this, new StringBuilder().append("Ringtone feature is not working"), Toast.LENGTH_LONG).show();
        }
    }

If you have the Ringtone selection part of it in a PreferenceScreen, you can create a RingtonePreference item in it which will let the user decide the ringtone. More on Preferences here and here, also for RingtonePreference

You can later Retrieve this ringtone using sharedPreferences and even set a default value for it. Take a look at this post too
