QUESTION
Moving from MVP to MVVM and trying to learn from tutorials on web.
Some of the tutorials state that ViewModel classes should not have any reference to Activity or View(android.view.View) classes.
But in some of the tutorials i've seen Views are used in ViewModel class and Activities to start other Activities using ViewModel. For example:
...ANSWER
Answered 2020-Mar-11 at 23:21From the documentation:
Caution: A ViewModel must never reference a view, Lifecycle, or any class that may hold a reference to the activity context.
This is because a ViewModel survives configuration changes. Let's say you have an activity and you rotate the device. The activity is killed and a new instance is created. If you put views in the viewmodel, then the activity won't be garbage collected because the views hold the reference to the previous activity. Also, the views themselves will be recreated but you're keeping old views in the viewmodel. Basically don't put any views, context, activity in the viewmodel.
Here's a sample from google: https://github.com/googlesamples/android-sunflower/

QUESTION
I need to register ProcessLifecycleOwner as described here Xamarin.Android Architecture Components in my Application.OnCreate method.
But it had resulted in the error with 6.2.2 version of MvvmCross:
MvvmCross.Exceptions.MvxIoCResolveException: Failed to resolve typeMvvmCross.ViewModels.IMvxAppStartoccurred
or just stuck on the Splash Screen with 6.2.3.
Those problems were fixed by advice from Xamarin.Android mvvmcross app crashes when launching with intent filter.
...ANSWER
Answered 2019-Mar-04 at 09:52Your approach is most likely blocking on the UI thread which us causing the UI to block during the time that the expected splash screen is suppose to show.
Try using an async event handler to allow for a non blocking UI call
QUESTION
I am using Android Databinding adapter and it says, it have to be static. So I am trying to make it non static and inject my classes into it with Dagger by following this tutorial. Although I can use my Picasso instance which is provided by dagger normally in app, it says Picasso cannot be provided without an @Inject constructor or an @Provides-annotated method.
I add @Inject annotation to my binding adapter constructor but still get same error
...ANSWER
Answered 2019-Feb-13 at 08:51As error said, dagger could not resolve Picasso dependency. In your case, the problem is that differenct dagger components can use directly only those dependencies, that interface marked with @Component annotation declared using methods. To allow AppComponent share Picasso with BindingComponent you need modify app component like that:

I have the next code

Answered 2019-Jan-14 at 13:21For two-way data binding, you need to use the = operator, as in:
android:text="@={loginViewModel.email}"
QUESTION
I'm struggling to use the ProgressBar in the MVVMCross structure of Xamarin Android. Originally, I wanted to bind the visibility of the ProgressBar to a field in my ViewModel. That proved difficult, I tried several permutations and tried suggestions from here: How to set visibility for ProgressBar in android MvvmCross Xamarin
I do have other elements such as buttons I have been able to successfully bind else where in my project, so I'm not sure why that was such a big issue. After many tries I decided to try setting the Visibility pragmatically in the ViewModel. I've tried several methods but what I finally thought would for sure work doesn't.
Xaml:

Answered 2018-Sep-12 at 16:22Turns out the issue was the Linker removing the Visibility property. I got the idea from this post: Visibility binding fails

QUESTION
I am working on Dagger2. I am planning to have same architecture defined in this project. I am getting below error.
...ANSWER
Answered 2018-May-31 at 03:45Your component does not know where to get DBHelper since no one provides it. Notice that you have a provider for DataManager that requires an instance of PatientDatabase. PatientDatabase is annotated with @Inject in constructor so it is added to the graph. But the problem lies in the dependencies of the PatientDatabase. To solve your problem, you should also provide your dbHelper and preferenceHelper instance in the module.
Try adding this to your module
QUESTION
I would like to create a gridview of movie posters images with using bindings.
My viewmodel looks like that:
...ANSWER
Answered 2017-Jan-24 at 22:18You probably didn't intend to use an instance method for the BindingAdapter.
If you do, you must provide a DataBindingComponent so that the generated Binding class knows which instance to use.
You have two options -- provide a DataBindingComponent or just pass the required context as an attribute to a static binding adapter method. The second is a bit easier to understand, so I'll start with that:
QUESTION
So I started a new project, mostly copying the architecture from https://github.com/MindorksOpenSource/android-mvvm-architecture
I have it all almost compiling, I think, but for some reason my LoginActivityBinding class isn't found at compile time even though the IDE seems to find it, it doesn't show me red text and I can do control+b and it takes me to the layout file.
This is my class:

Answered 2018-Feb-20 at 18:01Since this is meant to be a Kotlin project but I had just copied some Java files, I decided to search for this issue with Kotlin and turns out what I needed was this line kapt "com.android.databinding:compiler:2.3.3" on my dependencies.

Answered 2017-Jul-31 at 13:36I was facing the same issue with SupportMapFragment in MVVM. For interim solution, i have used mapview instead of SupportMapFragment.
First you need to create one method in CustomBinding.

Install Android-Mvvm
You can use Android-Mvvm 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-Mvvm 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 .
