Not observing the NetworkBoundResource to update the UI

[vivekpanchal]

i would like to know that how to observe the changes in the mainActivity ..ie
like when network call is made and failed then how do you observe those changes
and you are not using the NetworkboundResource to update the UI like this ...

`if (listResource.data != null) {
                        switch (listResource.status) {
                            case LOADING: {
//                                if(mRecipeListViewModel.getPageNumber() > 1){
//                                    mAdapter.displayLoading();
//                                }
//                                else{
//                                    mAdapter.displayOnlyLoading();
//                                }
//                                break;
                            }

                            case ERROR: {
                                Timber.e("onChanged: cannot refresh the cache.");
                                Timber.e("onChanged: ERROR message: %s", listResource.message);
                                Timber.e("onChanged: status: ERROR, #recipes: %s", listResource.data.size());
//                                mAdapter.hideLoading();
//                                mAdapter.setRecipes(listResource.data);
//                                Toast.makeText(RecipeListActivity.this, listResource.message, Toast.LENGTH_SHORT).show();
//
//                                if(listResource.message.equals(QUERY_EXHAUSTED)){
//                                    mAdapter.setQueryExhausted();
//                                }
//                                break;
                            }

                            case SUCCESS: {
                                Timber.d("onChanged: cache has been refreshed.");
                                Timber.d("onChanged: status: SUCCESS, #Recipes: %s", listResource.data.size());
//                                mAdapter.hideLoading();
//                                mAdapter.setRecipes(listResource.data);
                                break;
                            }`

kindly help me understand as I don't see that you are using anywhere the Resource Generic to handle the UI updates.
