I encountered the same issue and I end up using NoNonsense-FilePicker

Add to gradle file

compile 'com.nononsenseapps:filepicker:4.0.0'

Trigger file/folder/dir pick

try {

                    Utils.makeHepticFeedback(getActivity());

                    Intent selectDirectoyIntent = new Intent(getActivity(), FilePickerActivity.class);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_ALLOW_MULTIPLE, false);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_ALLOW_CREATE_DIR, true);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_MODE, FilePickerActivity.MODE_DIR);
                    selectDirectoyIntent.putExtra(FilePickerActivity.EXTRA_START_PATH, Environment.getExternalStorageDirectory().getPath());
                    startActivityForResult(selectDirectoyIntent, FILE_CODE);

                } catch (Exception e) {
                    Log.e(LOG_TAG, "exception", e);
                    e.printStackTrace();

                    Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_SHORT).show();
                }   

Handle Activity result to get selected file or files

 @Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (resultCode == Activity.RESULT_OK && requestCode == CHOOSE_IMAGE_REQUEST_CODE) {
                Uri selectedImageUri = data.getData();
                String selectedImagePath = getRealPathFromURI(selectedImageUri);


                // NOW WE HAVE OUR WANTED STRING
                if (selectedImagePath != null) {
                    System.out
                            .println("selectedImagePath is the right one for you!");

                    PreferenceHelper.getPreferenceHelperInstance().setString(getActivity(),
                            PreferenceHelper.PLAYER_BACKGROUND,
                            selectedImageUri.toString());

                    Glide.with(getActivity()).load(Uri.parse(
                            PreferenceHelper.getPreferenceHelperInstance().getString(getActivity(),
                                    PreferenceHelper.PLAYER_BACKGROUND
                                    , AppConstants.DEFAULT_BACKGROUND_URL))).
                            into((ImageView) ButterKnife.findById(getActivity(), R.id.play_back));

                }
            } else if (requestCode == FILE_CODE && resultCode == Activity.RESULT_OK) {

                if (null != data && !data.getBooleanExtra(FilePickerActivity.EXTRA_ALLOW_MULTIPLE, false)) {
                    // The URI will now be something like content://PACKAGE-NAME/root/path/to/file
                    Uri uri = data.getData();
                    // A utility method is provided to transform the URI to a File object
                    File file = com.nononsenseapps.filepicker.Utils.getFileForUri(uri);
                    // If you want a URI which matches the old return value, you can do
                    Uri fileUri = Uri.fromFile(file);
                    // Do something with the result...

                    Snackbar.make(fileFormat, "Recording folder updated to" + fileUri.getPath() + " ¯\\_(ツ)_/¯ ", Snackbar.LENGTH_SHORT).show();

                    AppConfig.RECORDING_FOLDER = fileUri.getPath();

                    PreferenceHelper.getPreferenceHelperInstance().setString(getActivity(), PreferenceHelper.RECORDING_FOLDER, AppConfig.RECORDING_FOLDER);

                    setUpSettingValue();

                } else {

                    // Handling multiple results is one extra step
                    ArrayList paths = data.getStringArrayListExtra(FilePickerActivity.EXTRA_PATHS);
                    if (paths != null) {
                        for (String path : paths) {
                            Uri uri = Uri.parse(path);
                            // Do something with the URI
                            File file = com.nononsenseapps.filepicker.Utils.getFileForUri(uri);
                            // If you want a URI which matches the old return value, you can do
                            Uri fileUri = Uri.fromFile(file);
                            // Do something with the result...

                            Toast.makeText(getActivity(), "Selected dir" + fileUri.getPath(), Toast.LENGTH_SHORT).show();


                        }
                    }
                }
            }

        }
