[DEPRECATED] Firebase Vertex AI Sample for Android (Kotlin)

Caution

On May 20, 2025, we released the Firebase AI SDK (firebase-ai). This SDK replaces the previous Vertex AI in Firebase SDK (firebase-vertexai) to accommodate the evolving set of supported features and services.

The new Firebase AI SDK provides Preview support for the Gemini Developer API, including its free tier offering.
Using the Firebase AI SDK with the Vertex AI Gemini API is still generally available (GA).

If you're using the old firebase-vertexai, we recommend migrating to firebase-ai because all new development and features will be in this new SDK.

The quickstart sample app for firebase-ai can be found in the /firebase-ai directory.
