            In clean MVP, who should handle combining interactors?
            Asked 2019-Apr-12 at 16:21

            I've seen good examples of MVP architecture (here and here). Both present only simple interactors, but I wonder how to deal with more complex use case, consisting of steps, which are repeated in other use cases.

            For example, my API requires token to authenticate any call. I've created an interactor to get that token (GetToken). I want to get user's last login date (GetLastLoginDate) and then fetch a list of changes that occured between that date and now (GetVersionChanges).

            Where those interactor should be chained? I want to keep them separate, because some of them are reused in other parts of the code. I've came up with two solutions.

            1. Presenter should chain all interactors. This solution works as long the use case is not complex and doesn't have many preconditions. It seems to me it's not the right place, because it burdens presenter with another responsibility.

            2. Interactor can use many repositories (no clean architecture rules are broken then). Why not use TokenRepository in other interactors? Because getting token is much more complex than just reaching to repository. Repeating the steps in other interactor does not reuse already existing code.

            Both solutions have their flaws and are against basic principles (DRY, single responsibility principle).

            ...

            ANSWER

            Answered 2019-Apr-12 at 16:21

            If I were you I would just put the logic of getting a token in a separate interactor (maybe named getTokenInteractor) and call that interactor from your others interactor who may need it. That way, it would be in an interactor that you chose either to use a token (and call or not your getTokenInteractor) and also in an interactor that you retrieve it and deal with errors. I would do the same for your "getVersionChanges" use case and let an interactor chain the calls.

            Let's imagine you have a presenter who needs to display the version changes. He will call a first interactor (GetVersionChangesInteractor) who will first check if he has a token (by calling getTokenInteractor), then call GetLastLoginDateRepository for retrieving the date, and call GetVersionChangesRepository with that date and finally give the result to your presenter.

            That way, your business logic can stay 100% in your interactor and your presenter can focus on how he will display that on screen.

            By the way, if your API needs a token for every call you should move it in an Interceptor so you do not have to deal with it at every call.

            Clean architecture: Use CompositeDisposable in domain or presentation/app
            Asked 2018-Aug-07 at 04:34

            I just start learn and apply CleanArchitecture for my Android project.
            I see there are 2 great source for following here
            1) https://github.com/android10/Android-CleanArchitecture
            2) https://github.com/fiveagency/Reedly (https://five.agency/android-architecture-part-4-applying-clean-architecture-on-android-hands-on/)

            Currently, the first source use the CompositeDisposable in domain (inside UseCase) and the second source use in presentation/app(Presenter/ViewModel)

            As my current understand, I see the benefit when we put CompositeDisposable in Presenter/ViewModel.

            • Easy to dispose (because if we CompositeDisposable in UseCase, for each UseCase we need to dispose call 1 time)
            • May easy to combine many UseCase (eg: UseCase1 execute then flatMap/zip... with UseCase2)

            I see the benefit when we put CompositeDisposable in UseCase

            • It separate RX from presentation

            I don't know if is there any other pros/cons of 2 approach. I never use CleanArchitecture for real project and I know when we follow any approach, it's quite hard to change to another approach.

            For me, currently I think I will choose: put CompositeDisposable in UseCase. What should I use? Is there any other approach?
            Any help or advice would be great appreciated.

            When it comes to clean architecture, I have been using 1) Android-CleanArchitecture for about a year now. And when it comes to disposing CompositeDisposable, I would do it in Presenter if I were you, because it is closely related to life-cycle of View and it controls data flow which CompositeDisposable in this case kind of belongs to.

            Suggestion:

            Convert 1) Android-CleanArchitecture from MVP to MVVM in Presentation layer with ViewModels and dispose your CompositeDisposable there. MVVM with Googles new ViewModel library eliminates headaches of managing life-cylce dependent objects yourself, which MVP in this CleanArchitecutre template fails to deliver.

            Hope this cleared things up a bit. Good Luck :)

            How to setup a project for Clean architecture in gradle?

            So I was going through clean architecture in android, really liked it how people even create separate projects for domain, data and presentation layer. I tried to create my own project for clean architecture but couldn't set up different projects for domain, data and presentation layers.

            How can I accomplish this kind of project architecture? https://github.com/android10/Android-CleanArchitecture

            Create one project as your main project of type Android Application Project. The separate layers can be added as library modules to your main project.

            Then you just need to add these library modules to your gradle file as dependencies. Android studio will usually take care of that. But just in case you needed to change the order of dependencies, you can do that in the gradle files of each module.

            Getting NullPointException when using Dagger2 and setRetainInstance(true);
            Asked 2018-Jan-26 at 10:45

            So I was following Clean Architecture to design my application. I have an Activity with a view pager which has two Fragment in it. Im injecting the PagerAdapter for this through Dagger.

            I understand that calling setRetainInstance(true) on a fragment prevents it from getting destroyed, and that getActivity() on such fragment may return a problem if the Activity is destroyed. I'm getting a NullPointException when trying to resume my activity after it has been on background and the activity has been (presumably) destroyed.

            So my question is

            • Is there a better way to accomplish what I'm trying to do?
            • Any resource someone can point me to?
            • Also uncertain why the Fragment and the Adapter is still active if the fragment has been destroyed. I get no memory leaks with LeakCanary.

            My activity has an Dagger Component MainActivityComponent which is injected as follows. And also extends HasComponent. For more info on this refer to HasComponent

            Problem

            The problem occured when the application stays in the background for a while and a recently displayed activity is recycled by Android. Bringing back the application causes NullPointerException (NPE) as the activity’s component is called by the fragment before it is initialized (both fragment and activity are recreated at the same time).

            Solution

            Introducing two lifecycle methods in BaseFragment class.

            1. onInjectView() — called to do an optional injection on onCreate(Bundle) and if an exception is thrown or false returned, it is called on onActivityCreated(Bundle) again. Within this method you can get the injection component and inject the view. Retrun true if the injection was succesfull, then it will not be called again.
            2. Based on returned value, the second method is called. The method is named onViewInjected(Bundle), as it is called only when the fragment has been injected and injected fields can be initialized.

            Android app clean architecture: Should data layer have its own model classes?
            Asked 2017-Dec-20 at 11:05

            What´s the best approach when developing an Android app and trying to follow clean architecture guidelines (but not extremely strict - cause that may be overkill for smaller projects).

            In my case, I am unsure which approach is the best (if there is a best one) regarding the data layer and if the data layer should operate on its own model classes or if it may operate directly on the domain layer models.

            Also, if the data layer should operate on its own model classes, should data sources like DB or API have their own models (like for an API using Retrofit and Gson a model class with Gson annotations) and then map to data layer models OR should the data layer model itself be the model returned by DB and API (this means the data layer model must be annotated for Gson being able to parse it in case of Retrofit and Gson).

            This is the case in this project: https://github.com/android10/Android-CleanArchitecture/blob/master/data/src/main/java/com/fernandocejas/android10/sample/data/entity/UserEntity.java

            The following images should clarify the 3 approaches I mean:

            If I were you, I would go with the Image1 process. I think it is the job of your datasource to take whatever object is coming from your database or API or any endpoint you have and transform it into something easier to user in your repository.

            Between Image1 and Image2, I think it depend of what data you want to store and what is the object you want to store. You may or may not need an ArticleEntity depending of your business rules. And if you don't need it, you don't have to create one.

            But for some use case you may need to create that object to add some informations to your Article. For exemple, if you want to place in that a validity date or any other information that you will only use in your repository, you can go for Image2.
