broadcastreceiver - Service does not send broadcast to Activity -

i have made app listens copies user makes in other apps , pastes text activity. service use listening copies works great recognizing copied text when want send broadcast activity, "onreceive" method not called.

this service code listening , sending data activity:

 @override public int onstartcommand(intent intent, int flags, int startid) {      cm = (clipboardmanager) getsystemservice(clipboard_service);      cm.addprimaryclipchangedlistener(this);      return start_sticky; }   @override public void onprimaryclipchanged() {       string copiedtext = cm.gettext().tostring();     mydynamictoast.informationmessage(getapplicationcontext(), copiedtext);      intent sendcopy = new intent(getapplicationcontext(), createnoteactivity.class);     sendcopy.putextra("copiedtext", copiedtext);     localbroadcastmanager.getinstance(getapplicationcontext()).sendbroadcast(sendcopy); } 

and @ activity:

 private val receivecopy = object : broadcastreceiver() {     override fun onreceive(context: context?, intent: intent?) {          log.d("acreceiver", "called")          val copiedtext = intent?.getstringextra("copiedtext")         mydynamictoast.informationmessage(context, "copied text is:" + copiedtext)      } }  override fun onresume() {     super.onresume()     localbroadcastmanager.getinstance(this).registerreceiver(receivecopy, intentfilter(".services.clipboardservice"))  }  override fun onpause() {     super.onpause()     localbroadcastmanager.getinstance(this).unregisterreceiver(receivecopy) } 

as can see have registered , unregistered broadcast receiver onreceive method not called. have missed here? thank you.
