Android implementation

[elile]

Hi,
I’m trying to implement function calling on Android.

First, I used the Hammer model with its formatter, but it either crashes on parseResponse or always returns hasFunction = true.

Then, I tried the Gemma model with its formatter, but it only returns plain text.

My goal is to implement a use case where:

1. I invoke a tool and receive a JSON response.

2. I then feed this JSON back into the model to generate a human-like text output.

How can I achieve this?
