I know this has been asked before but my problem is strange and I couldn't find an answer.
I have a parent class where a member is declared protected
class BaseContoller<G: BaseContract.BasePresenter, F: BaseModel> {
protected var presenter: G? = null
// ...
}
In each of BaseController's descendants, I refer to presenter with no problem as it is accessible in the same package and subclasses.
One BaseController's descendant has to be extended by other classes too but I have to do one check before of performing certain actions in where presenter is referenced again
class BackupPrinterController<G: BackupPrinterContract.Presenter, F: BaseModel>: BackupController<G, F>
private fun startScan() {
if(this is PrinterAssociationController) {
PrinterConnection.onConnection = { presenter?.onDeviceConnected(it) }
// ...
}
}
}
The strange behaviour comes here, presenter is perfectly accessible only without the filter if(this is PrinterAssociationController), with that if statement, when the onConnection callback is invoked, an IllegalAccessError exception is thrown by presenter
Here is the declaration of PrinterAssociationController
class PrinterAssociationController: BackupPrinterController<PrinterAssociationContract.Presenter, PrinterAssociationModel>(),
PrinterAssociationContract.View
and here is the exception
java.lang.IllegalAccessError: Method 'package.common.base.BaseContract$BasePresenter package.common.base.BaseController.getPresenter()' is inaccessible to class 'package.project.features.shared.controllers.BackupPrinterController$startScan$1' (declaration of 'package.project.features.shared.controllers.BackupPrinterController$startScan$1' appears in /data/app/package.project-1/base.apk:classes2.dex)

My app works fine after downloading Dynamic Feature onDemand Module but as soon as I restart my app the app crashes with Exception.
Heres the code that I copied from google dynamic features [sample repo][1]
private fun onSuccessfulLoad(moduleName: String, launch: Boolean) {
if (launch) {
when (moduleName) {
pagesfeatures -> launchActivity(mainActivity)
}
}
}
I have already overridden the code in BaseActivity and App class
open class BaseActivity: AppCompatActivity() {
override fun attachBaseContext(newBase: Context?) {
super.attachBaseContext(newBase)
SplitCompat.install(this)
}
}
public class App extends Application {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
SplitCompat.install(base);
}
}
But its crashing when I revisit the application
The Exception thats occurring in my logs Crashlytics

In my case, when there’s a configuration change it also regenerates the Context in my Activity, and loses the resources that have been injected by SplitCompat. I fix it by loading the resources using ContextCompat.
ContextCompat.getDrawable(context, drawable)
And reinject resource when there`s configuration changes using this in activity
override fun onConfigurationChanged(newConfig: Configuration) {
SplitCompat.installActivity( baseContext ?: this)
super.onConfigurationChanged(newConfig)
}

Please tell me what am I doing wrong and how to fix it? Thanks
fragment
class ActivateDeviceFragment : Fragment(R.layout.fragment_activate_device) {
private val viewModel: ActivateDeviceViewModel by inject()
// ....
}
view model
class ActivateDeviceViewModel constructor(
private val activateDeviceUseCase: ActivateDeviceUseCase,
) : ViewModel() {
init {
fetchDevices()
}
private val exceptionHandler = CoroutineExceptionHandler { coroutineContext, throwable ->
Timber.tag("test").d(throwable)
}
private fun fetchDevices() {
viewModelScope.launch(exceptionHandler) {
}
}
}
koin modules
val useCaseModule = module {
single { ActivateDeviceUseCase() }
}
val viewModelModule = module {
viewModel { ActivateDeviceViewModel(get() }
}
It is not related to Koin.
The log shows that the exceptionHandler in viewModelScope.launch(exceptionHandler) is actually null, and which throws NullPointerException.
It is because you trigger the fetchDevices() inside init{}, in which the instantiation of exceptionHandler is not ready (means it is null).
Therefore, you should not call fetchDevices() inside init{}. For example, you could call this in your Fragment onViewCreated(){ viewModel.fetchDevices } instead. It will be fine.
This is the summary of some codes which I am trying to implement.
button.setOnClickListener {
showSomeAnimation()
CoroutineScope(Dispatchers.IO).launch { // this line is UserActivity.kt:138
someNetworkTasks()
withContext(Dispatchers.Main) {
updateUI()
}
}
}
However, once I press the button, java.lang.VerifyError occurs:
E/AndroidRuntime: FATAL EXCEPTION: main

I thought that there can be some errors on my code and exception weren't printed definitely because the code is inside of lambda. So I extracted all of codes which are in button.setOnClickListener to a function to see what is the problem of my code like this:
fun foo() {
showSomeAnimation()
CoroutineScope(Dispatchers.IO).launch {
someNetworkTasks()
withContext(Dispatchers.Main) {
updateUI()
}
}
}
button.setOnClickListener {
foo()
}
But it worked really well without any exception. Why did this strange thing happen to me?
Try using
GlobalScope.launch {
someNetworkTasks()
}
updateUI()
Hope this helps
Please if you want to devote question write reason to improve.
The problem is I dont know how to implement the eventbus in presenter with Kotlin. It works fine if I implement and subscribe in activity class but when I am trying the same code in the presenter I got an exception. Might be something in Kotlin way of implementation. There must be nothing wrong with eventbus setting up because implementation in view works fine
My activity => constructor of presenter
private val mMainPresenter = MainPresenter(this, MainInteractor(), this)
My presenter
class MainPresenter(var mMainView: MainInterface?, val mMainInteractor: MainInteractor, val mContext : Context){
/**
* Checking if user have language otherwise show list of games
*/
fun checkingLanguage() {
if(mMainInteractor.getUserLanguage() == "") mMainView?.callLanguageDialog()
else EventBus.getDefault().post(LanguageEvent (mMainInteractor.getUserLanguage()))
}
fun registerSubscribers() {
if (!EventBus.getDefault().isRegistered(mContext)) {
EventBus.getDefault().register(mContext)
}
}
#Subscribe
fun inflateGamesList(event: LanguageEvent){
mMainView?.showGamesList(event.language)
} }

If you want to listen to events in presenter, you should register presenter, and not activity (context). So,
fun registerSubscribers() {
if (!EventBus.getDefault().isRegistered(this)) {
EventBus.getDefault().register(this)
}
}
Bug
I was found an issue when I try to open fragment and then replace with the same fragment.

Steps to reproduce the behavior:
I have BottomNavigationView once I tap on existing fragment which is visible, getting above crash.
Koin version: 2.0.1
Module
val viewModelModule = module {
scope(named<BrowseTaskFragment>()) {
scoped { BrowseTaskVM() }
}
}
Application class
startKoin {
androidContext(this#AbcApplication)
modules(listOf(appModule, stateModule, apiModule, viewModelModule))
}
You can do this by create scope.
First in your module class create scope by named koin method
val viewModelModule = module {
scope(named<BrowseTaskFragment>()) {
scoped { BrowseTaskVM() }
}
}
Second in your fragment
private val viewModelScope = getKoin().getOrCreateScope("Scope1",named<BrowseTaskFragment>())
private val browseTaskVM: BrowseTaskVM= viewModelScope.get()
Last in an onDestoy method close your scope.
override fun onDestroy() {
super.onDestroy()
viewModelScope.close()
}
define in application class like this
startKoin {
androidContext(this#ApplicationContext)
// your modules
modules(listOf(your modules))
}
and pass context in you modules
