public class dialogfrag extends dialogfragment {      asynctask<void,void,void> asynctask;           @override         public dialog oncreatedialog(bundle savedinstancestate) {    alertdialog.builder alertdialog=new alertdialog.builder(getactivity());               alertdialog.settitle("solution:");              view view = getactivity().getlayoutinflater().inflate(r.layout.dialogfrag,null);              final myview myview= (myview) view.findviewbyid(r.id.myview);             myview.setvisibility(view.invisible);     alertdialog.setview(view);    asynctask=new asynctask<void, void, void>() {                 @override                 protected void doinbackground(void... voids) {                      //compute here                  }                  @override                 protected void onpostexecute(void param) {                     super.onpostexecute(param);                                           getdialog().findviewbyid(r.id.progress).setvisibility(view.gone);                     myview.setvisibility(view.visible);                 }             });               asynctask.execute();                  alertdialog.setpositivebutton("show", new dialoginterface.onclicklistener() {                 @override                 public void onclick(dialoginterface dialoginterface, int i) {                     if(!(asynctask.getstatus()== asynctask.status.finished)){                         asynctask.cancel(true);                     }                      asynctask=null;                       dismiss();                 }             });                alertdialog.setnegativebutton("cancel", new dialoginterface.onclicklistener() {                 @override                 public void onclick(dialoginterface dialoginterface, int i) {                      if(!(asynctask.getstatus()== asynctask.status.finished)){                         asynctask.cancel(true);                     }                      asynctask=null;                     dismiss();                 }             });               dialog dialog=alertdialog.create();             dialog.getwindow().getattributes().windowanimations = r.style.mydialogviewanimation;              return dialog;         }           @override         public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {             getdialog().getwindow().setgravity(gravity.center_horizontal | gravity.top);             getdialog().requestwindowfeature(window.feature_no_title);             return super.oncreateview(inflater, container, savedinstancestate);         }

what $ next class dialogfrag in dialogfrag$1 means ?

$number means anonymous inner class, example new view.onclicklistener() {...}.

but can see next dialogfrag$1 total count 7 , mean have memory leak?

maybe, did rotate phone 7 times?

remember unregister listeners , broadcastreceivers in appropriate lifecycle methods. try avoid static fields.
