cometchat-android-v6-events

Ground truth: catalog android-v6.json + the live pages events (the API reference) and customization-events. CometChatEvents lives in chatuikit-core-android (com.cometchat.uikit.core.events.CometChatEvents). Verify symbols against the catalog; fetch the exact sealed-class members from the docs page — the event lists below are a MAP, the page is the manual.

Companion skills (read first)

• cometchat-android-v6-core — install, credentials, initFromSettings → login → render, the fetch map. Assumed here, never repeated.
• cometchat-android-v6-{kotlin,compose}-customization — click/selection callbacks on a single component (usually the simpler answer than the global bus).

Use this skill when

"tell me when a message is sent/edited/deleted", "run code when a call is accepted", "update my own badge when a conversation changes", "hook into group/member changes", "what's the difference between an SDK listener and a UI Kit event?".

Prerequisites & install

Same kit + init as core. CometChatEvents ships in chatuikit-core-android (already a transitive dependency of both cohort artifacts) — nothing to add.

The event bus (BAKED map — fetch the page for each sealed class's members)

All events come from the CometChatEvents singleton; each domain exposes a SharedFlow of a sealed class:

Member shapes are prefixed too and the message ones repeat the domain: CometChatMessageEvent.MessageSent(message, status) (status IN_PROGRESS/SUCCESS/ERROR) · MessageEdited · MessageDeleted · MessageRead · TextMessageReceived · TypingStarted · ReactionAdded. There is no .Sent — it is .MessageSent. Import the sealed class from com.cometchat.uikit.core.events. Full list: fetch /ui-kit/android/customization-events.md (NOT events.md, which still teaches the old un-prefixed shape).

Subscribing per cohort (lifecycle is the whole point)

Kotlin XML Views — collect in lifecycleScope; the coroutine is cancelled when the lifecycle owner is destroyed:

import androidx.lifecycle.lifecycleScope       // in an Activity/Fragment
import kotlinx.coroutines.launch
import com.cometchat.uikit.core.events.CometChatEvents
import com.cometchat.uikit.core.events.CometChatMessageEvent

lifecycleScope.launch {
    CometChatEvents.messageEvents.collect { event ->
        when (event) {
            is CometChatMessageEvent.MessageSent -> { /* event.message, event.status */ }
            is CometChatMessageEvent.MessageDeleted -> { /* event.message */ }
            else -> Unit
        }
    }
}

Jetpack Compose — collect in LaunchedEffect; cancelled when the composable leaves composition:

LaunchedEffect(Unit) {
    CometChatEvents.messageEvents.collect { event -> /* when (event) { … } */ }
}

No manual removal needed. Unlike the old static-listener pattern, SharedFlow collection is scoped — do NOT invent an addListener/removeListener pair for CometChatEvents. Just don't collect outside a lifecycle-aware scope (a bare GlobalScope.launch IS a leak).

UI-Kit events vs Chat SDK listeners (pick the right bus)

Common pitfalls

Collecting on a non-lifecycle scope (leak) · inventing CometChatEvents.addListener/removeListener (doesn't exist — it's a flow) · using a UI-Kit event to detect incoming messages (use an SDK message listener) · registering an SDK listener and never removing it · a when without an else branch breaking on a new sealed member · re-collecting the same flow in several places and double-handling · guessing a sealed-class case name instead of fetching the events page.

Verify it works

Compile against the pinned kit (./gradlew :app:assembleDebug # in YOUR app (npm run verify:fences:android-v6 is a pack-repo gate)). On device: trigger the action (send/edit/delete a message, accept a call) and confirm your handler runs exactly once; rotate the screen / navigate away and back — no duplicate handling and no crash (proves the scope is right); for any SDK listener you added, confirm the matching remove runs on teardown.
