// 1) Initialize (recommended in Application.onCreate)
//    apiHost is required: your account's QwenCloud API Host (copied from the API Key page in the QwenCloud console)

    ),

// 2) Inject the QwenCloud gateway API Key (as the Bearer token)
HappyOyster.updateToken(qwenApiKey)

            // Paused is the signal that pauseTravel has actually taken effect (asynchronous, see below); sendInstruct is still allowed here.
            TravelStatusValue.Paused -> markTravelPaused()
            // Terminal states: the SDK has already ended and released resources; clean up the host-side experience state.
            TravelStatusValue.Completed, TravelStatusValue.Failed -> clearActiveTravel()

// 4) Start the experience (the ticket is delivered by your server)

        // you cannot start a second Travel concurrently within the same App). Calling again while an experience is in progress throws
        // SDKError(103004), whose raw carries only a redacted summary of the ticket currently playing, never the full ticket.
        val travel: StartTravelData = HappyOyster.startTravel(ticket)
        currentTravel = travel

        // Inspect the returned Travel metadata first, then decide how to interact:
        //   travel.mode          —— directing / adventure / acting
        //   travel.creationModel —— Simple / ScriptList
        //   travel.aspectRatio   —— Acting only; use to set player orientation

            travel.creationModel != CreationModelValue.ScriptList
        // Note: calling sendInstruct in ScriptList mode throws SDKError(103002); script content is not managed through this SDK.

        // 5) Mount the video View (the SDK returns the view; you add it to the layout)
        //    Acting: size the container from travel.aspectRatio first, then attachVideo() (see §13 Mode Adaptation) —
        //    the remote view is bound clip-to-fill, so a mismatched container orientation crops the picture.
        val videoView = HappyOyster.attachVideo()
        binding.videoContainer.addView(videoView)

        // 6) In-run interaction — you must wait for running before sending:
        //    - sendCommand (adventure): valid only in running; calling in init/pending/paused returns 103002.
        //    - sendInstruct (directing / Acting): valid in running or paused; calling in init/pending returns 103002.

    } catch (e: SDKError) {
        // Handle start failure (e.g., 103004: an experience is already playing)
    }
}

// 7) Pause / Resume (directing and Acting; rewind is directing only)
//    pauseTravel is asynchronous: the method's return only means "accepted"; the actual pause is determined by onStatusChanged(paused).
//    Be sure to wait for the paused callback before allowing resumeTravel.

    if (currentStatus == TravelStatusValue.Paused) {
        HappyOyster.resumeTravel()       // call only after paused
