performance - Possible to free Context from Singleton in Android to prevent memory leak -


i'm maintaining legacy project can't refactoring due limitations. found possible memory leak in below scenario.

pass fragment singleton class

foo.getinstance().setbar(fragment);

assuming static instance lives longer need it, approach null in ondestroy() method in fragment.

@override public void ondestroy(){     foo.getinstance().setbar(null);//to prevent memory leak     super.ondestroy(); }

i'm new memory leak area, correct me if there wrong :)

use weakreference in singleton
