Introduction

Typical usage flow: bind the preview view via AtomicPusher.shared.setView(view), start pushing via startPush(config), monitor state for state changes, and release resources via release().

Features

PusherState: Real-time pusher state, including connection state, statistics, and live room info.
PusherEvent: Pusher event callbacks, including error, live ended, kicked out, and other event types.

Subscribable Data

PusherState fields are described below:
Property
Type
Description
networkState
Connection state.
statistics
StateFlow<PusherStatistics>
Pusher runtime statistics.
pusherInfo
StateFlow<PusherInfo>
Pusher live room info.
totalViewerCount
StateFlow<Int>
Total viewer count.

API List

Function
Description

Add pusher event callback listener.
Remove pusher event callback listener.
setView
Set the render view.
startPush
Start pushing (streaming).
stopPush
Stop pushing (streaming).
Update live room configuration.
release
Release pusher resources.
Enable advanced features by key-value pair.

Getting Instance

AtomicPusher.shared

Get the global singleton.

Observing State and Events

addListener

Add pusher event callback listener.
abstract fun addListener(listener: PusherListener?)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
listener
Listener.

removeListener

Remove pusher event callback listener.
abstract fun removeListener(listener: PusherListener?)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
listener
Listener.

View Management

setView

Set the render view. The locally captured video frames will be rendered into the given AtomicLiveView container.
abstract fun setView(view: AtomicLiveView)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
view
The render view container.

Push Control

startPush

Start pushing (streaming). Pass in the live room configuration; the SDK will create the push link accordingly.
abstract fun startPush(config: PusherInfo)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
config
Live room configuration.

stopPush

Stop pushing (streaming).
abstract fun stopPush()
Version
Supported since version 3.5.

updateConfig

Update live room configuration. Call this after startPush to update live room info such as name, cover, category etc.
abstract fun updateConfig(
    config: PusherInfo,
    modifyFlagList: List<PusherInfo.ModifyFlag>,
)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
config
Updated configuration.
modifyFlagList
List<PusherInfo.ModifyFlag>
Modify flags.

release

Actively release the pusher. After calling, all APIs become no-ops, and internally held underlying resources, state, and event subscriptions will be cleaned up.
abstract fun release()
Version
Supported since version 3.5.

Advanced Features

enableAdvancedFeature

Advanced feature. Enable an advanced feature by key-value pair. Supported keys depend on the underlying native pusher capability and may evolve over versions.
abstract fun enableAdvancedFeature(key: String, value: Any)
Version
Supported since version 3.5.
Parameters
Parameter
Type
Description
key
String
Feature key.
value
Any
Feature value, type depends on the specific key.

Data Structures

PusherCode

Atomic pusher error code enum, used to report push operation results and runtime errors.
Enum Value
Value
Description
OK
0
No error, operation succeeded.
ERROR_INVALID_PARAMETER
-1
Invalid parameter.
ERROR_INVALID_STATE
-2
The operation is not allowed in the current state (e.g. startPush again while pushing, updateConfig before startPush).
ERROR_START_PUSH_REQUEST_FAILED
-3
The startPush request chain failed (server / signaling / TRTC). See message for details.
ERROR_UPDATE_CONFIG_REQUEST_FAILED
-4
The updateConfig request chain failed (server / signaling). See message for details.

PusherConnectState

The connection state between the pusher and the push target. State machine (typical transitions):
                    startPush
  DISCONNECTED ─────────────▶ CONNECTING
      ▲                           │
      │                           │ join/push succeeded
      │                           ▼
      │                       CONNECTED
      │                           │
      │            network jitter / dropped, SDK auto-reconnects
      │                           ▼
      │                       CONNECTING
      │                           │
      │    reconnect succeeded ─▶ CONNECTED
      └─────  reconnect failed / stopPush / release
Note:
DISCONNECTED is the initial state; it is also returned to after calling stopPush / release. The auto-reconnect process reuses CONNECTING, without distinguishing "first connection" from "reconnecting".
Enum Value
Value
Description
DISCONNECTED
0
Not connected. Initial state, or after actively stopping the push / final reconnect failure.
CONNECTING
1
Establishing connection. Used for both the first room-join handshake and auto-reconnect after a disconnection.
CONNECTED
2
Connected, the push link is normal.

PusherListener

Pusher event listener, used to receive one-shot events such as push errors, live ended, kicked out, etc. Register/remove listeners via addListener / removeListener.
