AndroidAnnotations Rest view response data

Question

I am doing an API call using the Android Annotations RestService. The only problem is that I receive a JSON but I don't know how to see that JSON string. Is there a way I can view the response data so I can see the JSON string/content?

I tried using an ClientHttpRequestInterceptor but that only shows data of the request to the server and not the response.

Well, this is not easy, because when converting the response to JSON, it does not reads into a string, but reads to JSON step by step from the input stream directly. What you can do is sending the same JSON string from the server, but with text/plain content type. Then just use a String as response type and `StringHttpMessageConverter`. — WonderCsabo, Jun 18 '15 at 10:51
Or if you do not send a JSON, you can remove your JSON converter, and just read it with `StringHttpMessageConverter`. If you use JSON in the request, you cannot remove the converter when making the request, but you can remove it after it was created, in the interceptor. — WonderCsabo, Jun 18 '15 at 10:53
I can't change the API calls and I can't remove the JSON converter because the app won't launch anymore then. Does that mean it isn't possible for me at the moment? — Bart Bergmans, Jun 18 '15 at 11:04
You can remove the converter in the interceptor. But this is only for debugging, isn't it? — WonderCsabo, Jun 18 '15 at 11:16
Yes, it's only for debugging. How can I remove the converter in the interceptor then? — Bart Bergmans, Jun 18 '15 at 11:20
You can have a look at what I do to log the response of the rest api here : https://github.com/yDelouis/selfoss-android/blob/master/app%2Fsrc%2Fmain%2Fjava%2Ffr%2Fydelouis%2Fselfoss%2Frest%2FSelfossApiInterceptor.java. I use an interceptor and a wrapper of the HttpResponse. — yDelouis, Jun 18 '15 at 11:27
Never mind, @yDelouis' answer is much better. Just make sure to reset the stream after reading it, so your converter can also read it. — WonderCsabo, Jun 18 '15 at 11:49

Create this interceptor:

public class LoggingInterceptor implements ClientHttpRequestInterceptor {

    @Override
    public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
        ClientHttpResponse response = execution.execute(request, body);

        String responseString = stringOf(response.getBody());
        Log.d("RESPONSE", responseString);

        return response;
    }

    public static String stringOf(InputStream inputStream) {
        inputStream.mark(Integer.MAX_VALUE);
        BufferedReader r = new BufferedReader(new InputStreamReader(inputStream));
        StringBuilder strBuilder = new StringBuilder();
        String line;
        try {
            while ((line = r.readLine()) != null)
                strBuilder.append(line);
        } catch (IOException ignored) {}
        try {
            inputStream.reset();
        } catch (IOException ignored) {}
        return strBuilder.toString();
    }
}

And use this interceptor in your client:

@Rest(rootUrl = "your_url", converters = {your converters}, interceptors = LoggingInterceptor.class)
public interface Client {

   // methods
}

Based on this code.
