In your method under test, the
showLoading method is invoked with no attributes.. i think you should expect that and possibly verify that no error message has been shown:

Just because you use Dagger doesn't mean you have to use it for everything. It makes often more sense not to use Dagger for UI / View related things.
In this case the simplest approach would be to use the views context.

If your data from server is monolithic you should to use
Single because it return only once value. The
Observable will do when your data arrives in chunks.

I have this method that I am trying to pull data from an API, and then update the text view. Everything works except getRecipeName doesn't finish after the "end Method"
log. .getRecipeName() uses RetroFit to pull from an API.
I am currently learning MVP, Dagger, RxJava, and Butterknife all at once using Mindork's Github page on MVP Architecture
I commented out the .subscribeOn and .observeOn to see the result difference and nothing changed....

The reason is because your observable is returning jokeText every time it is subscribed upon. It returns immediately after invocation and will not wait for your network operation.
One possible solution is to use the RxJavaCallAdapter. Link here: https://github.com/square/retrofit/tree/master/retrofit-adapters/rxjava2
It will automatically convert your API returns to observables. No need to manually invoke retrofit requests. Just process the response and convert it to your desired object from there.
Another approach would be to wrap your entire sequence in an
I'm building an Android application using MVP. One of the screen displays data in a sort of Master/Detail view (a content page embedding a player):
At the top, there is the player (fragment) and below is the content info (viewpager with fragments), and user can swipe between pages (ViewPager) to switch between contents. When the Viewpager position changes, the player is updated accordingly and starts playing the current content.
Data requested by the presenter comes from a repository, with local(database)/remote(Rest API) datasources.
How can I make the best use of MVP to avoid requesting the same data multiple times?
Should I have only one Presenter in my Activity, and persist/cache data requested for the Content Info Info somewhere, to pass it back to the player when the position is changed?
Or is it better to have a presenter for each ContentInfo, requesting its own data, and a presenter for the player, requesting the same data again when the play() method is called?
I found this related topic, but it doesn't really fit to my case, as the data is not updated in the player at the same time that it is requested in the Content Info fragment (I'm fetching the data onCreate of the fragment by the ViewPager to have it already loaded when the swipe is done)....
ANSWERAnswered 2018-Jan-29 at 09:13
The best approach is to make individual components request the data from the repository, and handle the caching at repository level.
When the contents of ViewPager changes, just notify the player about the ID of a new content. The player will then fetch this content from the repository. The repository "knows" that this content has already been downloaded and serves it from the database instead of web.
If the database is not fast enough, it is possible to implement an in-memory caching inside the repository.
I was implementing MVP in my new application, then I came across a problem. I needed to call a method of
Activity) itself. It is by definition of MVP code separation, wrong thing to do.
The Presenter is in charge of the the orchestration between the Model and the View. It basically receive events from both and act consequently. The Presenter is the only component that knows others. It has a reference to the View and a another to the Model. (source)
In the same article it was mentioned that
View does not reacts to user interactions, it passes control to
Presenter to do the job. I have also read this SOF post about dependency rules.
In my case, I am using custom
AppTheme needs to be set before
setContent() call, what I am doing is create a method in
View interface called
setAppTheme() which my
Activity implements, and there is code to apply theme. Now the problem is, this is called within the app, which makes calling of a
View method inside its implementation.
To sum up, what my understanding of MVP either one of the following should be true:
setTheme()wont work after
onResume(), but will this satisfy MVP separation of M-V-P ?
Do not make interface method for
setAppTheme(), instead create a private method in
Activitywhich sets theme. This method will have nothing to do with any layer of MVP. But question is, if project is using MVP pattern, is this practice valid?

ANSWERAnswered 2017-Sep-06 at 08:04
Views in an MVP are supposed to be dumb. This is: they don't contain any logic. Just receive the event generated by the user and immediately delegate its work to the presenter. The
View can also inform the presenter that some events have happened (the view has been created, the screen rotate, etc)
This can lead to some confusions. Who is responsible of calling some methods? As you said the
View has to perform some actions like
setOnClickListener but the presenter is responsible of handling the event. Just have this in mind:
Viewis just an interface. This means that you can use anything that implements that interface
Right now you're making a mobile app. But if you wanted to code a console or a desktop app, the presentation logic doesn't change. Anything that is specific to the "View technology" (android, desktop, etc) should be performed inside the code specific to that technology. This way your code will be loosely coupled to your tech stack
I am learning Kotlin and Dagger 2 simultaneously by attempting to convert some of Mindorks advanced MVP sample to Kotlin but am having Dagger2 compile issues. I am swimming in classes here but am very close! Don't mind the untidiness, I intend to comb over each class once it compiles. If something is missing please let me know. The error comes down to my presenter class not being correctly injected into the activity. The error reads as follows:...

I am developing an Android application with MVP and RxJava. Well, I have a doubt:
When I am creating my presenter and interactor I can put me Schedulers in the presenter, like this:
Schedulers in the Presenter
ANSWERAnswered 2017-Jan-14 at 11:44
If you want to have good composability, I would recommend that you specify your schedulers as late as possible (unless necessary); this usually means right before subscribing. This way you can reuse f.e.
login() in another flow without having to thread-hop all the time.
However, this is like, just my opinion...
No vulnerabilities reported
You can use Android-MVP like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the Android-MVP component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
