A2aSessionManager

class A2aSessionManager(client: A2aGrpcClient, tenant: String)

Creates and tracks A2aSessions. Hold one per app (alongside the OtvSdkClient) so sessions outlive Activities. Sessions are in memory only and do not survive process death. Several sessions may be active at once; each has its own conversation context.

Functions

getSession

fun getSession(contextId: String): A2aSession?

Finds a managed session by its current context id.

resumeSession

@Synchronized

fun resumeSession(contextId: String, config: SessionConfig = SessionConfig()): A2aSession

Continues the conversation with the given server-issued contextId. If a live session already uses that id it is returned, so one conversation never has two sessions. Otherwise a new session starts with that id; if the server no longer knows it (contexts are kept about 30 minutes) it starts a new conversation and the session's A2aSession.contextId changes. Ids are not persisted by the SDK.

startSession

fun startSession(config: SessionConfig = SessionConfig()): A2aSession

Starts a session. It has no id yet: the server issues the context id with the first response, after which the session can also be found with getSession.

stopAll

suspend fun stopAll()

Stops every active session.

stopSession

suspend fun stopSession(session: A2aSession): Boolean

Stops and forgets the session. Returns false if it is not managed here.

suspend fun stopSession(contextId: String): Boolean

Stops the session with the given server-issued context id. Returns false if unknown.
