<Update label="February 6, 2026" tags={["Android"]} description="v3.0.0">
  ## Android SDK Release

  The Knot SDK now runs in a separate Android process. Android re-runs Application.onCreate() for every new process. Add this guard at the top of your Application.onCreate() to skip it for ours:

  ```kotlin lines wrap theme={"system"}
  override fun onCreate() {
      if (getProcessName()?.endsWith(":knotapi") == true) return
      super.onCreate()
      // ...
       }
  ```

  <Warning>
    Without this guard, SDK startup latency increases by however long your onCreate() takes to execute.
  </Warning>

  ## Simplification of SDK Initialization

  Versions `1.0.11` on iOS, `2.0.12` on Android, and `1.0.7` on React Native (with Flutter & JS to follow) remove the need to specify a `product` in `KnotConfiguration` when configuring the session to initialize the SDK. Now, simply choose a `type` for your session when calling [Create Session](/api-reference/sessions/create-session) and initialize the SDK with that session.
</Update>
