Why super.onDestroy() in java - Android goes on top in destructors? -


this question has answer here:

i new in java development! may tell me... according logic super.ondestroy(); in destructors goes on top? example:

protected void ondestroy() {             super.ondestroy();     releasemediaplayer(); }

and not

protected void ondestroy() {             releasemediaplayer();     super.ondestroy(); }

like c++, obj-c, pascal, etc ??

it depends on want in ondestroy. super.ondestroy (in order):

  • dismiss dialogs activity managing.
  • close cursors activity managing.
  • close open search dialog

if logic put inside ondestroy has 3 things android does, may have worry order. otherwise, , in of cases, not matter.
