Hi noob developer. We need to store it in a variable as the response body can only be consumed once in OkHttp.
When we call
response.body(), it reads the stream, processes it (converts it into a string) and closes it.
If we were to call
response.body().string() would be empty this time as the stream has already been consumed.
So storing it in a variable allows us to access it several times in the code.
Hope that helps :)
We can use response.body().string() without storing it in a variable and every thing would work the same...
But it's good coding practice to define and assign a jsonData variable once and then use it, instead of calling response.body().string() at multiple times. This is called Refactoring, which in this case, increases our code readability
