How does OkHttp get Json string?

Question

Solution: It was a mistake on my side.

The right way is response.body().string() other than response.body.toString

Answer 1

As I observed in my code. If once the value is fetched of body from Response, its become blank.

String str = response.body().string();  // {response:[]}

String str1  = response.body().string();  // BLANK

So I believe after fetching once the value from body, it become empty.

Suggestion : Store it in String, that can be used many time.
