I'm trying out the template code for the Gemini API Starter template when creating a new project in Android Studio.
The default template uses "gemini-pro" model which was deprecated long back (they didn't update the template), so I changed it to gemini-1.5-flash.
But I've been getting a parsing error:
com.google.ai.client.generativeai.type.SerializationException: Something went wrong while trying to deserialize a response from the server.

Has someone encountered this ?
Saw this similar question where the API wasn't returning the required field, but it was supposedly fixed (was another field): Gemini Api Android: SerializationException when deserializing response from server
Thanks in advance
I upgraded the generativeai dependency from 0.2.2 to 0.9.0 and now it works. Give that a try 👍
