NoSuchMethodError - static method comparison (java / util / Comparator)
I am sorting List
from java.util
using Gluon on an android device. The app is not going to be compiled for iOS (not enough bar) even with 8GB allocated, but that's another problem.
classpath 'org.javafxports:jfxmobile-plugin:1.3.4'
compile 'com.gluonhq:charm:4.3.2'
jfxmobile version = '3.2.4'
This is the line that is causing the crash:
highscoreList.sort(comparing(Highscore::getScore).reversed()); //#89

I started searching and I found this post about NoSuchMethodError so I tried to do the following but alas it still crashes and now I have no ideas
Comparator<Highscore> comparator = new Comparator<Highscore>() {
@Override
public int compare(Highscore highscore1, Highscore highscore2) {
return highscore1.getScore() - highscore2.getScore();
}
};
highscoreList.sort(comparator); //#97

Both Comparator#comparing()
and List#sort(Comparator)
have been added to the API level 24 and your device is probably working a lower API levels.
You would probably be in luck with the Collections#sort()
one that has been there since API level 1.

Just for your reference. I got this error while using http://www.vavr.io/ collections.
I called the toSortedSet () function of the LinkedHashSet . This function tries to call Comparator.naturalOrder () , which requires API level 24.
If you must use a lower level API, just use the toSortedSet (Comparator) overloaded function and pass in a suitable comparator.
