yes. watch working :

you can check event here like: dataevent

 public void ondatachanged(dataeventbuffer dataevents) {   (dataevent event : dataevents) {     if (event.gettype() == dataevent.type_changed &&         event.getdataitem().geturi().getpath().equals("/image")) {       datamapitem datamapitem = datamapitem.fromdataitem(event.getdataitem());       asset profileasset = datamapitem.getdatamap().getasset("profileimage");       bitmap bitmap = loadbitmapfromasset(profileasset);       // bitmap     }   } }
