Hey! So, I have a fragment which has a callback that receives the data from a JSON file that I am accessing using retrofit. Everything is working fine, and according to my log and my first run, the data IS being saved in my local arrays, and later I can access that data and display to the user.
However, when I open the fragment again and call a method to display data once again, the arrays that were previously full of data now are null.
Can anyone please enlighten me? I'm stuck!
here's my code:
