Fixed version (ground truth):

    RemoteInputView existing=(RemoteInputView)view.findViewWithTag(RemoteInputView.VIEW_TAG);
    if (existing != null) {
      existing.onNotificationUpdateOrReset();
    }
    if (existing == null && hasRemoteInput) {
      ViewGroup actionContainer=(FrameLayout)actionContainerCandidate;
      RemoteInputView riv=RemoteInputView.inflate(mContext,actionContainer,entry,mRemoteInputController);
      riv.setVisibility(View.INVISIBLE);
      actionContainer.addView(riv,new LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
      existing=riv;
    }
