The onItemChangeListener crashes

So I am currently working on a spinner that changes entries in a list. When loading into the Fragment and loading the List into the spinner adapter and setting up the onItemChangedListener everything works fine. But when the App goes to another Fragment and then goes back the app crashes with the following exception:

Bellow is the Listener and code surrounding it:
val spinner: Spinner = root.findViewById(R.id.store_select_spinner)
val spinnerAdapter: ArrayAdapter<String> = ArrayAdapter(
requireContext(), R.layout.spinner_item, llNames
)
spinnerAdapter.setDropDownViewResource(R.layout.spinner_item)
spinner.adapter = spinnerAdapter
spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
override fun onItemSelected(
parent: AdapterView<*>?,
view: View,
position: Int,
id: Long
) {
}
override fun onNothingSelected(parent: AdapterView<*>?) {
}
}

The error has been solved by the solution Demigod provided.
The code needs to be altered as the following:
spinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {
override fun onItemSelected(
parent: AdapterView<*>?,
view: View?,
position: Int,
id: Long
) {
StoreListFragment.storeAdapter.changeShelve(llShelveNames[position].first)
}
override fun onNothingSelected(parent: AdapterView<*>?) {
}
}

Actual/expect funs in shared throw NoSuchMethodError in Kotlin Multiplatform

I am developing a dummy weather app with the help of Kotlin Multiplatform. I am using Decompose and MVIKotlin to try and share all the business logic except the native uis, SwiftUI for IOS and Compose for Desktop and Android.
I am trying to have a expect composable (for dark theme and for loading of images)
// In common main
#Composable
expect fun isDarkMode() : Boolean
#Composable
expect fun loadWeatherIcon(id : Int) : Painter
// In android main
#Composable
actual fun isDarkMode() : Boolean {
return androidx.compose.foundation.isSystemInDarkTheme()
}
#Composable
actual fun loadWeatherIcon(id : Int) : Painter {
return painterResource(id)
}
//In Desktop main
#Composable
actual fun isDarkMode() : Boolean {
return false //isSystemInDarkTheme()
}
#Composable
actual fun loadWeatherIcon(id : Int) : Painter {
return loadWeatherIcon(id)
}
Meaning they are all implemented and there, but for some reason the crash is happening with NoSuchMethodError. I found some similar issues but they all had suspend funs and default parameters. Meanwhile my approach should work like in the jetpack todo compose sample, here's my project (if you want to test what's happening, you can just clone it and run it, it should crash immediatelly)

I/Process: Sending signal. PID: 17270 SIG:

I ran into a similar issue where a #Composable annotated expected function was not visible at runtime in a different Gradle module. Hence the java.lang.NoSuchMethodError exception. The solution was to make the expected function internal and have a public wrapper function delegate to that internal function.
Crashes:
#Composable
expect fun Image() { ... }
Does not crash:
#Composable
internal expect fun InternalImage() { ... }
#Composable
fun Image() {
InternalImage()
}

Android, Can add Fragment in XML, but not via Code [duplicate]

This question already has answers here:
Set Margin on RecyclerView programmatically
(5 answers)
ClassCastException of LayoutParams to MarginLayoutParams after setting a view's width
(2 answers)
Closed 3 years ago.
I have a fragment, that when added via XML, as
<fragment
class="my.fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="config" />
it is successfully added to the view, and i can interact with it.
However, when i try to add it programmatically, in a scrollview, as a second child as:
val layout = FrameLayout(this)
val params = FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT)
layout.layoutParams = params
layout.id = View.generateViewId()
scrollview_container.addView(layout, params)
val f2 = MyFragment.newInstance(Gson().toJson(asset))
val trans = supportFragmentManager.beginTransaction()
trans.add(layout.id, f2, "config")
trans.addToBackStack(null)
trans.commit()
i get the following error (sorry, it's long)

There is no application code in this stack trace, only Android SDK calls. I have also tried to add my fragment in a NavHostFragment, but i still get the same error.
Any ideas?
Thanks in advance!

Try to change below line in your code:
val params = FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT)
To:
val params = ScrollView.LayoutParams(ScrollView.LayoutParams.MATCH_PARENT, ScrollView.LayoutParams.MATCH_PARENT);

It seems your Fragment already have Layout Params.Except to change them you should modify existing params like this.
ViewGroup.LayoutParams params = yourfragment.getView().getLayoutParams();
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
params.height = ViewGroup.LayoutParams.MATCH_PARENT;
contactsFragment.getView().requestLayout();
The answer is in java language but you will get concept from here.

Android: getting IllegalAccessError only on built APKs

So I'm getting this error only when I'm running the APK and app crashes immediately. (no matter signed, unsigned release mode or debug)
but when I run the app from android studio, everything's fine.
I have both kotlin and java files in the project.
and the error is caused by a kotlin file by the way.
any idea ?
here's the error log:

and here's the onViewCreated method:
override fun onViewCreated(view: View?, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
adapter = MyAdapter(list)
adapter!!.addOnItemClickListener { pos , Data->
...
}
}
there's an interface in recyclerView's adapter which passes data on each item Click. once again, this code works on debug mode and I used this structure a lot in other java classes.
any help would be appreciated. This thing is driving me crazy !

RecyclerView error ConcurrentModificationException only API 23 & API 26

I get ConcurrentModificationException in my RecyclerView, only in APIs 23 & 26, how can I bypass this?
This is my RecyclerView Setup:
private void setUpRecyclerView() {
int maxIndex = 0;
if (game.size() < 3) {
maxIndex = game.size();
} else if (game.size() >= 3) {
maxIndex = 3;
}
recyclerView = findViewById(R.id.home_recycler_view);
adapter = new GameCardListMiniAdapter(this, game.subList(0, maxIndex));
recyclerView.setAdapter(adapter);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(ActivityHome.this);
linearLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
}
after I manipulate the data from game, I call recyclerView.swapAdapter(adapter, true); and get the error, but only in the afore mentioned APIs, in the rest of the APIs up to API 15 everything works just fine.
This is the stacktrace for API 23:

Tried to make it work creating the game.SubList outside,with a for loop instead of a SubList, didn't crash, but swapAdapter wasn't being called and the most strange thing is that is working wonderful in my phone, no crashes and the expected behavior.
I really,really apreciate some light.
Regards Ne0R#Cu

The root of this issue is that List.subList() does not copy the List:
/**
* Returns a view of the portion of this list between the specified
* fromIndex, inclusive, and toIndex, exclusive. (If
* fromIndex and toIndex are equal, the returned list is
* empty.) The returned list is backed by this list, so non-structural
...
Then, when you call size() on the resulting view, the exception is thrown. I haven't dug into why this happened, but size() tries to validate it's current size, which in this case is conflicted between the full list and the view.
So, you can remedy this crash by simply copying the list:
List<YOUR_TYPE> trimmed = new ArrayList<>( game.subList(0, maxIndex) );
adapter = new GameCardListMiniAdapter(this, trimmed);

Try
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
instead of :
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(ActivityHome.this);
then do the same thing ext
rc.setHasFixedSize(false);//only use this for fixed ammount
rc.setLayoutManager(layoutManager);
rc.setAdapter(dataItemAdapter);

I could not find any answer for my question, I ended up creating a HorizontalScrollView and adding my views from code to a LinearLayout within the HorizontalScrollView.
