    if error in String format:

    public Sring getErrorBodyAsString(RetrofitError error) {    
          return (String) error.getBodyAs(String.class)
    }
    

    if you need custom object:

    class ErrorResponse {
       @SerializedName("error")
       int errorCode;
    
       @SerializedName("msg")
       String msg;
    }
    
    public T getErrorBody(RetrofitError error, Class<T> clazz) {    
          return (T) error.getBodyAs(clazz);
    }

    Try this code:

    @Override
    public void failure(RetrofitError error) {
        String json =  new String(((TypedByteArray)error.getResponse().getBody()).getBytes());
        Log.v("failure", json.toString());
    }
    

    with Retrofit 2.0

    @Override
    public void onFailure(Call<Example> call, Throwable t) {
        String message = t.getMessage();
        Log.d("failure", message);
    }

    Your server should return 4xx HTTP error code to get this working.

    When your server returns HTTP 200 this mean successful response and it will be processed with onSuccess branch. Likely your object which you pass to Callback<Object> should be ready to handle both success and error result.

    To make sure this is the case you can check if RetrofitError is actually a JsonParseException by adding next snippet:

    public void failure(RetrofitError error) {
        Log.v(TAG, error.getMessage());
    };

    you need use getErrorStream() for this.

    If the HTTP response indicates that an error occurred, getInputStream() will throw an IOException. Use getErrorStream() to read the error response. The headers can be read in the normal way using getHeaderFields().
