Android AI Sample Catalog

This folder contains the Android AI Sample catalog, a stand alone application giving you access to individual self-contained samples illustrating some of the Generative AI capabilities unlocked by some of Google's models.

Note: These samples are intended to showcase specific AI capabilities in isolation, and they may use simplified code. They are demo not intended to be used as production-ready code. For best practices follow our documentation and check Now In Android

Requires Firebase setup the samples relying on Google Cloud models (Gemini Pro, Gemini Flash, etc...) require setting up a Firebase project and connecting the app to Firebase (read more here).

🚧 Work-in-Progress: we are working on bringing more samples into the application.

How to run

1. Clone the repository
2. Open the whole project in Android Studio.
3. Set up a Firebase project and connect your app to Firebase by adding your Firebase configuration file (google-services.json) to the /app directory. Read more in the Firebase documentation and the Android-specific setup guide.
4. Sync & Run app configuration

The app will open with the samples list screen that allows you to navigate throughout the different available samples.

Samples

Here is the list of samples you can find in the /samples folder:

Samples
	✨📱☁️ Hybrid Inference: A sample demonstrating a hybrid approach to generative AI, utilizing both on-device (Gemini Nano via ML Kit) and cloud-based (Gemini via Firebase AI SDK) models. It showcases how to fallback to the cloud when on-device capabilities are unavailable. > Browse code
	✨🖼️🍌 Gemini Image Chat: A chatbot app using the new Gemini 3 Pro Image model (a.k.a. "Nano Banana Pro") enabling image generation and iterations via conversation with the Gemini model. Ask the model to generate an image and ask for tweaks in the chat. > Browse code
	✨🗣️ Gemini Chatbot: A chatbot app using the Gemini Flash model. You can tweak the system instructions in the model configuration to change the tone or the persona of the model. > Browse code
	✨📸 Gemini Multimodal: A sample leveraging the multimodal capabilities of the Gemini Flash model (in this case text and image-to-text) to let you prompt the model with an image. > Browse code
	✨📱📰 On-device Summarization: A sample letting you summarize text on-device using Gemini Nano via the GenAI Summarization API. > Browse code
	✨📱🔍 On-device Image Description: A sample letting you generate image descriptions using Gemini Nano via the GenAI Image Description API. > Browse code
	✨📱🖋️ On-device Writing Assistance: A sample letting you proofread and rewrite text using Gemini Nano via the GenAI Rewriting API. > Browse code
	🖼️🍌 Nanobanana: A sample using Gemini 3.1 Flash Image model (a.k.a. "Nano Banana") to generate images of landscapes, objects and people in various artistic style. > Browse code
	🖼️📸 Magic Selfie: A sample using ML Kit subject Segmentation SDK to remove the background behind a person, and Nano Banana to generate new background. > Browse code
	✨🎥 Gemini Video Summarization: A sample using Gemini Flash to summarize videos leveraging the large file support. > Browse code
	✨🎥 Gemini Video Metadata Creation: A sample using Gemini Flash to generate thumbnails, descriptions, hashtags, account tags, chapters and links from a video. This sample leverages the ability to provide a Youtube video link to the model context for inference. > Browse code
	✨🗣️ Gemini Live API To-do App: A to-do list app using the Gemini Live API to let the user interact with Gemini via voice to update the todo list. > Browse code
