Android appwidget does not start service when ran -

-

the problem having when debug widget, changes layout, when run it, doesn't work. according debug messages, sets setonclickpendingintent not start service.

in short, widget works when debugging.

here widget code:

    public class widget extends appwidgetprovider {      public static string switch_screen1 = "1";     public static string switch_screen2 = "2";      public static final string add_note = "addnote";     public static final string manage_reminders = "managereminders";     public static string take_picture = "takepicture";       private static int layoutid = r.layout.widget_screen1;      /**      * method called when widget added home screen.      * sets listeners on items , updates screen info database      */     @override     public void onenabled(context context) {         super.onenabled(context);         setlisteners(context);         updatescreenfromdatabase(context, appwidgetmanager.getinstance(context), appwidgetmanager.getinstance(context).getappwidgetids(new componentname(context, widget.class)));     }       /**      * method called update widget. widget called when timeout set in widget.xml occurs.      */     @override     public void onupdate(context context, appwidgetmanager appwidgetmanager,int[] appwidgetids) {         super.onupdate(context, appwidgetmanager, appwidgetids);

            for(int = 0 ; < appwidgetids.length ; i++){                 string currentlesson = "no current lesson";                 string nextlesson = "no next lesson";                 lessonhour[] hours = database.getinstance(context).getcurrentandnextlessonhour();                 if(hours[0] != null){                     currentlesson = hours[0].getstart().get(gregoriancalendar.hour_of_day) + ":" + utils.adjustminutes(hours[0].getstart().get(gregoriancalendar.minute)) + " " + hours[0] .getlesson().getsummary();

                }                 views.settextviewtext(r.id.txt_widget_lesson1, currentlesson);                 views.settextviewtext(r.id.txt_widget_lesson2, nextlesson);                  appwidgetmanager.updateappwidget(new componentname(context, widget.class), views);               }         }      }        /**      * method called when screen of widget should change.      * action tells method screen should change.       * @param context      * @param action: screen method should switch to. either widget_screen1 or widget_screen2      */     public static void buildupdate(context context, string action){         remoteviews views;

        }         else if(action.equals(switch_screen2)){             views =  new remoteviews(context.getpackagename(), r.layout.widget_screen2);             appwidgetmanager.getinstance(context).updateappwidget(new componentname(context, widget.class), views);

                remoteviews views = new remoteviews(context.getpackagename(), layoutid);                  intent intent = new intent(context, switchwidgetscreenservice.class);                 intent.setaction(switch_screen2);                 intent.setdata(uri.parse("uri::" + math.random()));                 log.e("khlrooster", "action of listener screen 1: " + intent.getaction());                 pendingintent pi = pendingintent.getservice(context, 0, intent, intent.flag_activity_new_task);                 views.setonclickpendingintent(r.id.imgbtn_switchdown, pi);                 views.setonclickpendingintent(r.id.imgbtn_widget_notification, pi);                  manager.updateappwidget(new componentname(context, widget.class), views);                 log.e("khlrooster", "listeners set on widget screen 1");             }              else if(layoutid == r.layout.widget_screen2){                 log.e("khlrooster", "setting listeners on widget screen 2");                 remoteviews views = new remoteviews(context.getpackagename(), layoutid);                 intent intent2 = new intent(context, switchwidgetscreenservice.class);                 intent2.setaction(switch_screen1);                               pendingintent pendingintent = pendingintent.getservice(context, 0, intent2, 0);                 views.setonclickpendingintent(r.id.imgbtn_switchup, pendingintent);                  intent2 = new intent(context, lessondetail.class);                 intent2.setaction(add_note);                 pendingintent = pendingintent.getactivity(context, 0, intent2, 0);                 views.setonclickpendingintent(r.id.imgbtn_notes, pendingintent);                  intent2= new intent(context, lessondetail.class);                 intent2.setaction(take_picture);                 pendingintent = pendingintent.getactivity(context, 0, intent2, 0);                 views.setonclickpendingintent(r.id.imgbtn_photo, pendingintent);                                  manager.updateappwidget(new componentname(context, widget.class), views);                 log.e("khlrooster", "listeners set on widget screen 2");             }          }     }   }

and here service responding intents:

public class switchwidgetscreenservice extends service {  @override public ibinder onbind(intent arg0) {     // todo auto-generated method stub     return null; }  @override public void oncreate() {     super.oncreate();     log.e("khlrooster", "created switchwidgetscreenservice"); }  @override public void onstart(intent intent, int startid) {     //super.onstart(intent, startid);     log.e("khlrooster", "started switchwidgetscreenservice");     handleevent(intent); }  @override public int onstartcommand(intent intent, int flags, int startid) {     handleevent(intent);     log.e("khlrooster", "started switchwidgetscreenservice");     return super.onstartcommand(intent, flags, startid); }  private void handleevent(intent intent) {     log.e("khlrooster", "it works, screen changes to: " + intent.getaction());     if(intent.getaction().equals(widget.switch_screen1)){         widget.buildupdate(this, widget.switch_screen1);     }else if(intent.getaction().equals(widget.switch_screen2)){         widget.buildupdate(this, widget.switch_screen2);     } }

}

i solved problem, called setlisteners once more after getting data db.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
