                    .longRecognize(GOOGLE_API_KEY, getLongRecognize(f.getName()))
                    .enqueue(new Callback<String>() {
                        @Override
                        public void onResponse(Call<String> call, Response<String> response) {
                            if (response.isSuccessful()) {
                                String body = String.valueOf(response.body());
                                Log.d(TAG, "Response = " + body);
                            }
                        }

                        @Override
                        public void onFailure(Call<String> call, Throwable t) {
                            Log.d(TAG, "Throwable = " + t.getMessage());

                        }
                    });
        });
