Is it possible to delay the map method until the connection is complete? RxJava

Question

new Retrofit.Builder().baseUrl("...").addCallAdapterFactory(RxJava3CallAdapterFactory.create()).build().create(RetrofitAPI.class).getCategories().map(responseBody -> {

    //I want to handle the JSON here in my way but the result is empty because the map method is called before the connection is completed.

    return responseBody;
}).subscribe(new SingleObserver<ResponseBody>() {
    @Override
    public void onSubscribe(@NonNull Disposable d) {
        Log.w("ABC", "onSubscribe");
    }

    @Override
    public void onSuccess(@NonNull ResponseBody responseBody) {
        Log.w("ABC", "onSuccess");
    }

    @Override
    public void onError(@NonNull Throwable e) {
        Log.w("ABC", "onError - " + e.getMessage());
    }
});

I'm getting the JSON from the server and I want to handle it in my way inside the map method but the JSON is always empty.

Retrofit, the default value for OkHttp is 10 seconds. Retrofit relies on the OkHttp default value.

you should read about retrofit timeout and assign your value for example (30 seconds)

&& that's will be helpful OkHttp/Retrofit default timeout
