Participant left event not being received (intermittently)

[inddev1337-ship-it]

Describe the bug

We have a use case to end the call if there is only one participant and currently we poll every 15s for call.state.participants.value.size to check this.

However sometimes even though a participant has left, this still returns 2, since it is a 1v1 call.
Why is this happening? and how can we reliably know the participant count at any time.

SDK version
Android Video SDK - io.getstream:stream-video-android-ui-compose:1.8.0

To Reproduce
Happens intermittently

Expected behavior
How to reliably know if a participant has left

Device:

• Samsung A13
• Android version: 15

Hi there,

Instead of polling participants.value.size, react to the leave event — it's the deterministic signal for "a participant has actually left":

call.subscribeFor(ParticipantLeftEvent::class.java) {
    if (call.state.participants.value.size <= 1) {
        // you're alone — end the call
    }
}

Also worth noting: you're ~20 releases behind. You're on 1.8.0; the latest is 1.28.0. There have been a number of reconnection and participant-lifecycle fixes across those releases, several of which directly affect the behavior you're describing. Please upgrade and re-test — if it still reproduces on the latest version, let us know and we'll dig in further.

Regards
