android - Why does AppWidgetManager update Intent of all RemoteViews for Widgets? -


i have widget defined in android app maps specific lightswitch chosen configuration activity. each instance of widget can map different lightswitch , tapping widget toggles light on , off. here's code activity sets widget:

@override public boolean onoptionsitemselected(menuitem item) {     if (item.getitemid() != r.id.action_choose) {         return super.onoptionsitemselected(item);     remoteviews remoteviews = new remoteviews(this.getpackagename(), r.layout.device_widget);     remoteviews.setimageviewresource(r.id.widgetonoffbutton, android.r.drawable.star_big_off);      sharedpreferences.editor prefs = getapplicationcontext().getsharedpreferences(mywidgetservice.widget_prefs, mode_private).edit();     prefs.putint(mywidgetservice.widget_device_id + integer.tostring(mappwidgetid), mdeviceid);     prefs.apply();      intent clickintent = new intent(this.getapplicationcontext(), mywidgetprovider.class);     clickintent.setaction(appwidgetmanager.action_appwidget_update);     clickintent.putextra(appwidgetmanager.extra_appwidget_id, mappwidgetid);     clickintent.putextra(mywidgetservice.on_level, 100);      pendingintent pendingintent = pendingintent.getbroadcast(getapplicationcontext(), 0, clickintent, pendingintent.flag_update_current);     remoteviews.setonclickpendingintent(r.id.widgetonoffbutton, pendingintent);      mappwidgetmanager.updateappwidget(mappwidgetid, remoteviews); }

i've verified mappwidgetid new id widget. here's appwidgetprovider's code, use onreceive method can access extras in intent, have onupdate , ondelete defined intents fall outside normal click conditions:

@override public void onreceive(context context, intent intent) {      string action = intent.getaction();     int widgetid = intent.getintextra(appwidgetmanager.extra_appwidget_id, -1);     int onlevel = intent.getintextra(mywidgetservice.on_level, -1);      if(action == appwidgetmanager.action_appwidget_update && widgetid > -1 && onlevel > -1) {          intent newintent = new intent(context.getapplicationcontext(), wishfullwidgetservice.class);         newintent.putextra(appwidgetmanager.extra_appwidget_id, widgetid);         newintent.putextra(mywidgetservice.on_level, onlevel);         context.startservice(newintent);     }     super.onreceive(context, intent);      intent resultvalue = new intent();     resultvalue.putextra(appwidgetmanager.extra_appwidget_id, mappwidgetid);     setresult(result_ok, resultvalue);     finish();      return true; }

and code mywidgetservice. each time widget clicked, reset onclickpendingintent own widgetid , onlevel, widgets fire off pendingintent latest widget's id , onlevel.

@override public int onstartcommand(intent intent, int flags, int startid) {      appwidgetmanager appwidgetmanager = appwidgetmanager.getinstance(this.getapplicationcontext());     int widgetid = intent.getintextra(appwidgetmanager.extra_appwidget_id, -1);     int onlevel = intent.getintextra(on_level, -1);      remoteviews remoteviews = new remoteviews(this.getapplicationcontext().getpackagename(), r.layout.device_widget);     intent clickintent = new intent(this.getapplicationcontext(), wishfullwidgetprovider.class);     clickintent.setaction(appwidgetmanager.action_appwidget_update);     clickintent.putextra(appwidgetmanager.extra_appwidget_id, widgetid);      if(onlevel > 0) {         remoteviews.setimageviewresource(r.id.widgetonoffbutton, android.r.drawable.star_big_on);         clickintent.putextra(on_level, 0);     } else {         remoteviews.setimageviewresource(r.id.widgetonoffbutton, android.r.drawable.star_big_off);         clickintent.putextra(on_level, 100);     }      if(onlevel > -1) {         int deviceid = mprefs.getint(widget_device_id + integer.tostring(widgetid), -1);         sendmessagetodevice(onlevel, deviceid);     }      pendingintent pendingintent = pendingintent.getbroadcast(getapplicationcontext(), 0, clickintent, pendingintent.flag_update_current);     remoteviews.setonclickpendingintent(r.id.widgetonoffbutton, pendingintent);     appwidgetmanager.updateappwidget(widgetid, remoteviews);      stopself();     return super.onstartcommand(intent, flags, startid); }

at point, if have widget 1 , widget 2, clicking widget 1 fire intent containing id , onlevel of widget 2. how can update onclickpendingintent of each widget independently without newest 1 overwriting others?

pass unique int first flag (second parameter) of pendingintent, preferably widgetid.

pendingintent pendingintent = pendingintent.getbroadcast(getapplicationcontext(), uniqueid, clickintent, pendingintent.flag_update_current);

this cause android not override existing pendingintent, create new one.

here's link different post similar problem.
