# NotInitialized

class NotInitialized : [FrakError](/developers/references/android/id-frak-sdk-core/frakerror/)

Client method reached before [id.frak.sdk.Frak.initialize](/developers/references/android/id-frak-sdk/frak/initialize/). A `class`, not an `object`: `fillInStackTrace()` runs at construction, so a singleton would report the first call site.
