I'm trying to know when the animation close of the softkeyboard is done. So i try to use this function :
val rootLayout = findViewById<ConstraintLayout>(R.id.root_layout)
rootLayout.setWindowInsetsAnimationCallback(object : WindowInsetsAnimation.Callback(DISPATCH_MODE_STOP) {
override fun onProgress(insets: WindowInsets, runningAnimations: MutableList<WindowInsetsAnimation>): WindowInsets {
//TODO("Not yet implemented")
return insets
}
override fun onEnd(animation: WindowInsetsAnimation) {
super.onEnd(animation)
val showingKeyboard = rootLayout.rootWindowInsets.isVisible(WindowInsets.Type.ime())
if (!showingKeyboard) {
println("Keyboard is now closed")
}
}
})
but when i launch the app on my phone (and several emu) i have to face to this error :
java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/WindowInsetsAnimation$Callback;

I don't understand what i should do, thanks for your answers !
I finally found my mystake. this method is for API 30+. But i've found another way to achieve my goal :
This is work when i close by myself the soft keyboard.
imm.hideSoftInputFromWindow(rootLayout.windowToken, 0, object : ResultReceiver(null) {
override fun onReceiveResult(resultCode: Int, resultData: Bundle?) {
if (resultCode == InputMethodManager.RESULT_UNCHANGED_HIDDEN ||
resultCode == InputMethodManager.RESULT_HIDDEN) {
//Soft has finished the animation
}
}
}
})
Hope this answer help someone :)

I'm currently working on a project to practice dependency injection with Dagger-Hilt, however I can't get my ViewModel to instantiate, I've already looked at some other questions on the same topic, most point the issue to Gradle but that didn't fix it for me, all errors in the Stacktrace are from internal classes except for the 2 lines that involve my ViewModel within the MainActivity
Here is the Stacktrace:

Here is the ViewModel:
class DogViewModel #Inject constructor(
private val getDefaultImages: GetDefaultImages
) : ViewModel() {
val dogModel = MutableLiveData<DogModel>()
val isLoading = MutableLiveData<Boolean>()
fun onCreate() {
viewModelScope.launch {
isLoading.value = true
val result = getDefaultImages()
if(!result.isNullOrEmpty()) {
dogModel.value = result[0]
isLoading.value = false
}
}
}
And this is where I'm declaring it:
#AndroidEntryPoint
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
private val dogViewModel: DogViewModel by viewModels()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
dogViewModel.onCreate()
dogViewModel.dogModel.observe(this) {
initRecyclerView(it)
}
}
You should add #HiltViewModel annotation on top of your view model.
Make sure you have written #AndroidEntryPoint above your Fragment or Activity class.
You have to write #HiltViewModel above your ViewModel Class.
Also make sure you are providing all the dependencies written in ViewModel like repositories, etc.
If don't use getDefaultImages object in DogViewModel you can remove it and it will work. If you use it you need to pass an instance of GetDefaultImages class to the DogViewModel using ViewModelProvider.Factory:
#Suppress("UNCHECKED_CAST")
private val factory: ViewModelProvider.Factory = object : ViewModelProvider.Factory {
override fun <T : ViewModel> create(modelClass: Class<T>): T {
return DogViewModel(GetDefaultImages()) as T
}
}
private val dogViewModel: MyViewModel by viewModels { factory }

Android room persistent: AppDatabase_Impl does not exist
(29 answers)
Closed 12 months ago.
I am working on a notes application with room and ViewModel but while initializing the ViewModel inside activity, I am getting this
java.lang.RuntimeException: Cannot create an instance of class package.notes.homeScreen.HomeScreenVM
here is my main activity
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
private lateinit var viewModel: HomeScreenVM
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setUI()
setViewModel()
}
private fun setUI() {
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
}
private fun setViewModel() {
viewModel = ViewModelProvider(this, HomeScreenViewModelFactory(this.application))[HomeScreenVM::class.java]
}
}
and ViewModel is like-
class HomeScreenVM(application: Application) : AndroidViewModel(application) {
//some methods
}
and my viewmodelfactory is like-
class HomeScreenViewModelFactory(private val application: android.app.Application) : ViewModelProvider.AndroidViewModelFactory(application) {
#Suppress("UNCHECKED_CAST")
override fun <T : ViewModel> create(modelClass: Class<T>): T {
if (modelClass.isAssignableFrom(HomeScreenVM::class.java))
return HomeScreenVM(application) as T
throw IllegalArgumentException("Unknown model class")
}
}
I don't know where the problem is. Help me.
Thanks in advance.

I'm using build tools 30.0.3 and API level 30, with multidex enabled and imported in gradle
I have an Activity which is declared in my manifest like so
<activity
android:name="com.weare8.android.ui.sponsorHub.watchAndRespond.AWatchAndRespondCongrats"
android:screenOrientation="portrait"
android:theme="#style/App8Theme.noActionBar"/>
And specify the same class at the top of the Activity's file:
package com.weare8.android.ui.sponsorHub.watchAndRespond
I then have a method called "initData" that is called in the Activity's onResume method. The app crashes when it is called with the following stack trace:

I am learning android MVVM pattern android development. I wanted to create a recycclerview activity to show data from server. But it's not accepting my viewmodel class. Bellow is my logcat errors.

VIEWMODEL
Here is my viewmodel class. I am passing some data to activity from this viewmodel. But problem is activity does not accept this viewmodel. Maybe viewmodel has any issue.
class RecyclerActivityViewModel(application: Application) : AndroidViewModel(application) {
val repository = RecyclerActivityRepository(application)
fun userData(): LiveData<ArrayList<UserResponse>>{
return repository.getUserData()
}
}
REPOSITORY
class RecyclerActivityRepository(application: Application) {
var liveData = MutableLiveData<ArrayList<UserResponse>>()
private val userList = ArrayList<UserResponse>()
private var adapter: UserAdapter? = null
fun getUserData(): MutableLiveData<ArrayList<UserResponse>>{
if (liveData == null){
liveData = MutableLiveData<ArrayList<UserResponse>>()
}
RetrofitClient.instance.getUsers()
.enqueue(object : Callback<List<UserResponse>> {
override fun onFailure(call: Call<List<UserResponse>>, t: Throwable) {
Log.v("Retrofit", t.message.toString())
}
override fun onResponse(
call: Call<List<UserResponse>>,
response: Response<List<UserResponse>>
) {
Log.v("Retrofit", "Success")
Log.v("response_code", response.code().toString())
try {
userList.addAll(response.body()!!)
adapter?.notifyDataSetChanged()
}catch (e: Exception){
Log.v("error", e.message.toString())}
}
})
return liveData
}
}
ACTIVITY
Here is my logic code
class RecyclerActivity : AppCompatActivity() {
private lateinit var viewModel: RecyclerActivityViewModel
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_recycler)
viewModel = ViewModelProvider(this).get(RecyclerActivityViewModel::class.java)
}
}
this might help
viewModel= ViewModelProvider(this, ViewModelProvider.AndroidViewModelFactory.getInstance(this.getApplication())).get(RecyclerActivityViewModel::class.java)
When I set my application to background and open it again I have a crash:
java.lang.RuntimeException: Unable to destroy activity {MainActivity}: java.util.ConcurrentModificationException
I'm using navigation graph scope for storing viewmodel
fun <T : ViewModel> getViewModelForGraph(
graphId: Int,
clazz: Class<T>,
fragment: Fragment
): T {
val navController = NavHostFragment.findNavController(fragment)
val vmFactory = object : ViewModelProvider.Factory {
override fun <U : ViewModel?> create(modelClass: Class<U>): U =
Factory.getComponent(clazz) as U
}
return ViewModelProvider(
navController.getViewModelStoreOwner(graphId),
vmFactory
).get(clazz)
}
and I'm getting my viewmodel from fragment this way:
getViewModelForGraph(
R.id.my_sub_graph,
MyViewModel::class.java,
this
)
.getViewModelForGraph(
R.id.mySubGraph,
MyViewModel::class.java,
this
)
And problem resolves when I'm getViewModelForGraph and just attaching my viewmodel to the activity.
Am I using navGraph viewmodel storage in a wrong way?
