Switch User

VWOInsights.setUserId switches identity when the logged-in user changes in the same process. Call it only after VWOInsights.init has completed successfully.

Signature

fun setUserId(userId: String, initCallBack: IVwoInitCallback?): Boolean

public static boolean setUserId(String userId, IVwoInitCallback initCallBack)

Parameters

userId — Non-blank string. Blank values return false.
initCallBack — Optional. Invoked when configuration refresh finishes after the switch (vwoInitSuccess / vwoInitFailed), similar to init.

Returns

true — Request accepted locally; refresh started.
false — Rejected (blank userId, or SDK not initialized).

Behavior

Stops the current recording/session for the previous user.
Updates client identity and refreshes server configuration for the new userId.
If recording was active before the switch, it automatically resumes after configuration refresh completes. If recording was stopped, it remains stopped.
