Вещи Android с ошибкой Crashlytics

Question

Я использую Android Things Developer Preview 7. Без Crashlytics мое приложение работает правильно. Когда я устанавливаю fabric.Crashylitics на код:

Fabric.with(this, new Crashlytics());

Я получаю следующую ошибку:

     Caused by: io.fabric.sdk.android.services.concurrency.UnmetDependencyException: This app relies on Crashlytics. Please sign up for access at https://fabric.io/sign_up,
    install an Android build tool and ask a team member to invite you to this app's organization.

Crashlytics поддерживает Android-вещи?
