java - Android: dismissing dialogs containing listeners -

-

i'm working 2 classes, , model class , dialog class in android. model class keeps list of listeners, dialog adds to.

public class smartchannelmodel {      private list<onresultschanged> monresultschanged     public interface onresultschanged {         void onresultschanged(int changed);     }      public smartchannelmodel() {         monresultschanged = new list<onresultschanged>();     }      public void addresultlistener(onresultschanged listener) {         monresultschanged.add(listener);     } }

and dialog class:

public class infodialog extends appcompatdialog {     private smartchannelmodel model;     public infodialog(context context, smartchannelmodel model) {         super(context);         this.model = model;     }     public void update() {         //do stuff     }     @override     protected void onstart() {         super.onstart();         model.addonresultschanged(new onresultschanged() {             @override             void onresultschanged(int changed) {                 update();             }         });     } }

when create , dismiss dialog, garbage collection ever performed on since dialog added listener model class? need remove listeners i've added?

thank help!

as far know yes if there no other reference anywhere in class.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
