android - Loader is not retained after starting new activity, changing orientation in new activity and pressing back button -

i been running issue loaders lately. created small project reproduces issue https://github.com/solcott/loaders-orientation-change

i have simple activity adds fragment

public class mainactivity extends activity {    @override   protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     fragment mainfragment = getfragmentmanager().findfragmentbyid(r.id.main_fragment);     if(mainfragment == null){         log.w(getclass().getsimplename(), "creating new fragment");         mainfragment = new mainfragment();         getfragmentmanager().begintransaction().add(r.id.main_fragment, mainfragment).commit();     }   } } 

in fragment start loader returns integer displayed on screen. there button starts new activity:

public class mainfragment extends fragment implements loadercallbacks<integer> {  private static int next_val = 0;  textview text1;  button button1;  @override public void onactivitycreated(bundle savedinstancestate) {     super.onactivitycreated(savedinstancestate);     getloadermanager().initloader(1, null, this); }  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate); }  @override public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {     return inflater.inflate(r.layout.fragment_main, container, false); }  @override public void onviewcreated(view view, bundle savedinstancestate) {     super.onviewcreated(view, savedinstancestate);     text1 = (textview) view.findviewbyid(android.r.id.text1);     button1 = (button) view.findviewbyid(android.r.id.button1);     button1.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             startactivity(new intent(getactivity(), nextactivity.class));         }     }); }  @override public loader<integer> oncreateloader(int id, bundle args) {     asynctaskloader<integer> loader = new asynctaskloader<integer>(             getactivity()) {          @override         public integer loadinbackground() {             return next_val++;         }     };     loader.forceload();     return loader; }  @override public void onloadfinished(loader<integer> loader, integer data) {     text1.settext(data.tostring()); }  @override public void onloaderreset(loader<integer> loader) {     // todo auto-generated method stub  }  } 

up point works fine can change orientation , integer displayed doesn't change. can start new activity , hit button , integer displayed doesn't change.

however, when navigate new activity, change orientation , press button integer incremented. expect behave same way did without orientation change.

calling setretaininstance(true) in fragment.oncreate() make worse. onloadcomplete never called , integer not displayed @ all.

has else run issue , found workaround?

same question asked here: loader unable retain during configuration change

this damn annoying problem asynctask loaders. although solution proposed in thread, think general consensus avoid asynctaskloaders.
