java.lang.NoSuchMethodError: No interface method sort(Ljava/util/Comparator;) exception in sorting arraylist android

Question

I\'m trying to sort an ArrayList in Java in Android app but I\'m getting this weird exception.

Code:

eventsList.sort(new Comparator<         


        

Answer 1

What if you try

Collections.sort(eventsList, new Comparator...

As far as I know ArrayList doesn't have sort method.
