I have been following a course on Android Development and making a trivia app that uses a json. I have to use a singleton to get the data from the web. So here is a file QuestionBank.java, which will get the data from web and put it into a logd (for now just to test). Then, once it is working, I'll have to code it to put the data in a Question object:

my code is like this, i don't know why it's getting an empty array even though i added the elements to the array during request.

public class MainActivity extends AppCompatActivity {

I'm trying to initialize a global ArrayList from within a listener (to deal with JSONArray objects from the Volley library in different places of the code). However, when I try to access it in the Oncreate method it seems to be uninitialized.

I tried the same with different static and non-static variables i.g. int[], String, etc. but the problem seems to persist.

NOTE: The Question class is used for app development purposes:
