How can I parse the following response value? It contains both .wav file and json data. The service gives two content types. Somebody Content-Type: application/json; charset=utf-8 Content-Disposition: form-data; name=Json the other Content-Type: audio/wav Content-Disposition: form-data; filename=AudioFromTts.wav; name=AudioFromTts Content-Encoding: binary

How can I parse them? I need to play the audio file. I need to show Text in Json data on screen

Showing the wav part as the json section is pretty straight forward.

To decode the wav file you need to create an interface like so . @Streaming would let retrofit know that it is streaming data that is being processed

//On your api interface
@POST("path/to/your/resource")
@Streaming
void apiRequest(Callback<POJO> callback);

restAdapter.apiRequest(new Callback<POJO>() {
        @Override
        public void success(POJO pojo, Response response) {
            try {
                //you can now get your file in the InputStream
                InputStream is = response.getBody().in();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void failure(RetrofitError error) {

        }
    });
