userManager.currentUser was called too often. I was not able to prove that a bug is related to it but i think it may fix some hidden bugs.
CurrentUserProviderImpl is now used throughout the code to access the current user.
userManager.currentUser is only used from CurrentUserProviderImpl whenever the _currentUser was null (should only happen on app startup)
To avoid multiple initialization of CurrentUserProviderImpl it was changed to be a @Singleton
The handling should soon be replaced with coroutine flows. However for the v21.0.0 release it's still done with RxJava to avoid bugs.

It could happen that when sending a message it was received on server but if the servers response is not received, the retry was triggered in the talk app.
This sometimes happened when internet connection was not the best.
Best would be that messages with the same referenceId would be refused on server side, but this won't be the case for now. So messages with the same referenceId are NOT refused as this would be too much overhead as there would be additional queries on server for every received message)
For now, the automatic retry logic is just removed so duplicated messages won't be created automatically.
However it's still possible to manually trigger the retry via button. In this case it is not guaranteed that there won't be duplicates.

when being offline and no messages are set -> hide shimmer
when messages are received -> hide shimmer and "offlineNoMessages"-info

Because long polling may have to be informed that the scopep was cancelled, the isActive checks are added so it can't happen that messages are added when they shouldn't.
I could not reproduce the scenario, anyway the checks should make sense in my opinion.

This is necessary especially to cancel the long polling when configuration change was made, e.g. screen was rotated. Otherwise multiple long polling requests would be running after configuration changes.
Because it not possible to launch a new coroutine in a scope that was canceled, it is necessary to re-initialize the scope.

if chatMessageList is empty after handleSystemMessages it makes no sense to call the following methods.
Also processMessagesFromTheFuture was executed which caused that the popup was shown.
A better solution for the future should be to handle(remove) the "to-hide" system messages already in the repo or viewmodel

The idea to show the progress bar (aka shimmer animation) was that it show not be shown at all if loading messages happens in less than a second (this was a better UX in my opinion).
The idea was to hide the progress bar when
ChatMessageStartState was triggered.
However there can be moment when adapter is still empty after ChatMessageStartState and if in this moment the DELAY_TO_SHOW_PROGRESS_BAR is reached before the adapter is actually filled, the overlay happens.
It could be a solution to move the hiding of the progress bar, however then special cases might have to be handled.
For simplicity, the logic for DELAY_TO_SHOW_PROGRESS_BAR is removed. Progress bar is always shown without a delay so it wont be triggered on a later moment and can't overlay the chat.

By using
networkMonitor.isOnline.first()
the function
unregisterNetworkCallback
was triggered, which sometimes causes the ConnectivityManager$TooManyRequestsException.
So each time isOnline.first() was called, the callbackFlow would:
- Register a new NetworkCallback.
- Emit a value and cancel the flow.
- Unregister the NetworkCallback.
The exception was:
Exception android.net.ConnectivityManager$TooManyRequestsException:
at android.net.ConnectivityManager.convertServiceException (ConnectivityManager.java:3771)
at android.net.ConnectivityManager.sendRequestForNetwork (ConnectivityManager.java:3960)
at android.net.ConnectivityManager.sendRequestForNetwork (ConnectivityManager.java:3967)
at android.net.ConnectivityManager.registerNetworkCallback (ConnectivityManager.java:4349)
at android.net.ConnectivityManager.registerNetworkCallback (ConnectivityManager.java:4319)
at com.nextcloud.talk.data.network.NetworkMonitorImpl$isOnline$1.invokeSuspend (NetworkMonitorImpl.kt:61)
To fix this, the cold flow from callbackFlow is converted to a StateFlow.

If user sent a message as a first message in today's chat, the temp message will be deleted when messages are retrieved from server, but also the date has to be deleted as it will be added again when the chat messages are added from server. Otherwise date "Today" would be shown twice.

reason was that the UI was not yet loaded but isScrolledToBottom was already called, so findFirstVisibleItemPosition returned -1.
Fix for now is to return true for isScrolledToBottom when position is -1
They does not solve the root cause for now. It should be made sure the code is not executed until UI is ready.
A quick try with
repeatOnLifecycle(Lifecycle.State.STARTED)
when collecting getMessageFlow did not help.

(as datasources should be only used in repositories)
use coroutines instead RxJava for api calls triggered by MessageInputViewModel
