How to create such a variable that it would work in all classes?

Question

Java

In general, guys, please help, I ran into 1 problem, and I just can’t solve it. I am making an android app. And I ran into the fact that I need to run 2 AsyncTasks, and the second one should be called from the first one, and after the end of the work, pass the bmap (Bitmap) variable to it. I kind of made it public, but in 1 AsyncTask it is stubbornly not defined. What to do?

Answer 1

No need to make such a heavy object visible to everyone!
Refactor code. Get to know the Listener pattern

Answer 2

Can be passed to the constructor.
Make it public (if it doesn't show, then the class object hasn't been created).
Without creating a class object - public static ...
