[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.
