AI Model Setup

The ONNX models are not included in the repository because of file size limitations.

You must manually add the required model files before building the project.

Required Files

Download the following from the Hugging Face CLIP ONNX repository:

• vision_model.onnx
• text_model.onnx
• vocab.json

Recommended source:

https://huggingface.co/Xenova/clip-vit-base-patch32

Placement

Place the files inside:

app/src/main/assets/

Final structure:

app/
└── src/
    └── main/
        └── assets/
            ├── vision_model.onnx
            ├── text_model.onnx
            └── vocab.json

---

Build

After adding the models:

Clean Project

./gradlew clean

Build APK

./gradlew assembleDebug

Or directly build and run from Android Studio.
