Session Lifecycle (Android)

Manage session and stream state in DAT SDK integrations.

Create a Session with Wearables.createSession(...), start it, then attach capabilities such as camera streaming. Session lifecycle and stream lifecycle are related but distinct.

Session states

State	Meaning	App action
IDLE	Session created, not started yet	Call session.start()
STARTING	Connecting to the device	Show loading UI
STARTED	Session active and ready for capabilities	Add or use capabilities
PAUSED	Session temporarily suspended	Keep state, wait for resume or stop
STOPPING	Session is shutting down	Stop user work and wait
STOPPED	Session ended	Release resources and create a new session if needed

Observe session state

val session = Wearables.createSession(AutoDeviceSelector()).getOrElse { error ->
    throw IllegalStateException(error.description)
}
session.start()

lifecycleScope.launch {
    session.state.collect { state ->
        when (state) {
            DeviceSessionState.STARTED -> onStarted()
            DeviceSessionState.PAUSED -> onPaused()
            DeviceSessionState.STOPPED -> onStopped()
             -> 
        }
    }
}
