Okhttp: FATAL EXCEPTION: OkHttp Dispatcher

[PassersHowe]

I'm having a trouble, use a Google search, but did not find a solution：

compile 'com.squareup.okhttp3:okhttp:3.3.1'
Tested devices: XiaoMi Redmi Note3 with Android 5.0.2

line

25     @Override
26    public List<SpaceCategory> obtainSpaceCategory(final String url) {
27        String url2 = "http://192.168.6.248/MVPDemo/Home/Space/space";
28        OkHttpClient okHttpClient = new OkHttpClient();
29        Request request = new Request.Builder().url(url2).build();
30        Call call = okHttpClient.newCall(request);
31       call.enqueue(new Callback() {
32            @Override
33           public void onFailure(Call call, IOException e) {
34           }
35
36            @Override
37           public void onResponse(Call call, Response response) throws IOException {
38              Log.d("MainImpl","response : " + response.body().string());
39                String result = response.body().string();
40            }
41        });
42
43       return spaceCategories;
44    }

It's an error to call ResponseBody.string() multiple times. The documentation explains why.
