android - onDetroy() is called after calling onPause() -

i develop cocos2d-x android.

my question when user press power button, called ondestroy() after calling onpause(). connencted memory leak problem? why ondestroy() called @ time? when returns app on resume mode, doesn't go current screen. goes main screen. think it's connected problem- ondestroy() called after calling onpause(). right?

@override public void onpause(){     super.onpause();     ccdirector.shareddirector().pause(); }  @override public void ondestroy(){     super.ondestroy();     ccdirector.shareddirector().end(); } 

thank help.

when send activity background destroyed time os. check if low on memory or try running application on device more memory if have one. times helps if restart phone.
