Experiment variation is not changes but feature value is changing, right?

feature value is not changed, too

Have you tried to pass other attributes map instead of using setAttribute()?

is there other way to set attributes, except GBSDKBuilder(attributes).initialized() or setAttributes(map)?

The documentation describes passing user attributes through constructor same as in Javascript SDK

for example with usecase, use experiment with featureFlag key (“featureKey”) at first, when starting the application, I called

growthBook = GBSDKBuilder(
    apiKey = context.getString(R.string.key_growth_book),
    hostURL = "<https://cdn.growthbook.io/>",
    attributes = mapOf("userId", "lastLoginedUserId"),
).initialize()

attributes is set for last user, getFeature(featureKey) returns A then user logout, I need to change attributes. so I called

growthBook.setAttribute(mapOf("userId" to ""))

then call getFeature(featureKey) returns A again, expected value is B.

Have you exactly configured that if userId is empty than feature value should be B or you just point that feature value should be different?

i will show my test code.

I see. Maybe evaluateFeature() method don't work right but to make sure I will also need to know how feature rule configured (if configured)
