When I tried to implements the NetworkBoundResource and Resource helper class for the Room Db and Retrofit, it works perfect. However, I need to implement the Search Result from RESTful using Retrofit only without Room . The Resources class is good and I dont need to change it. What I want to do is try to remove db source inside this class. public abstract class NetworkBoundResource<ResultType, RequestType> { private final AppExecutors appExecutors; private final MediatorLiveData<Resource<ResultType>> result = new MediatorLiveData<>(); @MainThread public NetworkBoundResource(AppExecutors

I have next use case: User comes to registration form, enters name, email and password and clicks on register button. After that system needs to check if email is taken or not and based on that show error message or create new user... I am trying to do that using Room, ViewModel and LiveData. This is some project that on which I try to learn these components and I do not have remote api, I will store everything in local database So I have these classes: RegisterActivity RegisterViewModel User UsersDAO UsersRepository UsersRegistrationService So the idea that I have is that there will be

I have a service which provides UI that is visible to user most of the time. I was experimenting with new Application Architecture when I came with a problem. MyModelviewModel viewModel = ViewModelProviders.of(this).get(MyModelviewModel.class); But as you know this can be only AppCompat or Fragment Is there some alternative? or can I put observer directly on my LiveData like Im puting on ViewModel viewModel.getList().observe(Playground.this, new Observer<List<TestEntity>>() { @Override public void onChanged(@Nullable List<TestEntity> items) { recyclerViewAdapter.addItems(items); } }); LiveData

I am using 2-way data binding to update a LiveData String object from my ViewModel with a string set in the EditText: <android.support.design.widget.TextInputEditText android:id="@+id/writeReviewTitle" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@={viewModel.liveReviewTitle}" /> So, from my understanding, the ViewModel would have its liveReviewTitle attribute updated every time the text changed in the EditText. I assume this is happening through the usage of a TextWatcher or some sort of listening mechanism that is being taken care of for me by the

I am working on a screen that shows the contents of a Room wrapped DB using a recycler. The adapter gets the LiveData from a ViewModel that hides the query call on the Room DAO object. So, the LiveData object is actually a ComputableLiveData object that is aware of changes to the Room DB. Now I want to add filter options to the screen. Where / how would I implement this in this Room-LiveData-ViewModel setup? Should the adapter or ViewModel "postfilter" the results in the LiveData? Should I requery the data from room for every filter change? Can I reuse the underlying (Computable)LiveData for
