Crash on start: NoSuchMethodError FlowKt.asFlow(BroadcastChannel) with kotlinx-coroutines 1.8+/1.9+ (Tangem SDK 3.9.2)

[ShengXiuyan]

Summary
Using Tangem SDK 3.9.2 together with kotlinx-coroutines 1.8.x / 1.9.x causes a runtime crash:

java.lang.NoSuchMethodError: No static method asFlow(Lkotlinx/coroutines/channels/BroadcastChannel;)Lkotlinx/coroutines/flow/Flow; in class Lkotlinx/coroutines/flow/FlowKt;
    at com.tangem.common.core.CardSession$start$2.invokeSuspend(CardSession.kt:184)
    ...

It looks like SDK still relies on BroadcastChannel.asFlow(), which was removed in modern coroutines.

Environment
Tangem SDK: com.github.tangem.tangem-sdk-android:android:3.9.2 and :core:3.9.2
Kotlin: (e.g.) 1.9.x
kotlinx-coroutines: 1.9.0 (also reproducible with 1.8.x)
Android: reproducible on multiple devices/emulators
Build system: Gradle/AGP (standard setup)

Repro steps

1. Initialize SDK with a custom SessionViewDelegate (custom UI instead of Tangem’s native dialog).
   Example (shortened):

val nfcManager = TangemSdk.initNfcManager(activity)
val sdk = TangemSdk(
    reader = nfcManager.reader,
    viewDelegate = CustomCardManagerDelegate(activity),
    secureStorage = SecureStorage.create(activity),
    wordlist = Wordlist.getWordlist(activity),
    config = Config(),
    nfcAvailabilityProvider = object : NfcAvailabilityProvider {
        override fun isNfcFeatureAvailable() = 
            NfcAdapter.getDefaultAdapter(activity)?.isEnabled == true
    }

2. Start a card session (e.g., scan a card).
3. App crashes with NoSuchMethodError shown above.

SDK references BroadcastChannel.asFlow(...). BroadcastChannel and related extensions were deprecated and then removed in modern coroutines; in 1.8+/1.9+ there is no such method at runtime.

This leads to a binary incompatibility when the app (or its dependencies like Firebase/Play Services) resolves coroutines to 1.8+/1.9+.

Request
Please migrate SDK internals away from BroadcastChannel to SharedFlow/StateFlow/Channel (or other modern Flow primitives) and publish a new release built against kotlinx-coroutines 1.9.x (or at least 1.8+).

If a pre-release already exists that removes BroadcastChannel, a pointer to that version would be highly appreciated.

Additional context
Custom SessionViewDelegate methods updated to the new signatures in 3.9.x (productType param, etc.) compile and run fine; the crash happens inside CardSession.start.

We look forward to a fix and a new release of Tangem SDK with support for the latest coroutines.

I can confirm the same issue with Tangem SDK 3.9.2 and kotlinx-coroutines 1.9.0. The app crashes with NoSuchMethodError due to BroadcastChannel.asFlow() when starting a session.
