# AndroidControl Test Set (JSON)

## Overview

This dataset provides the **test split** of [AndroidControl](https://arxiv.org/abs/2405.01958) in a ready-to-use JSON format, extracted from the original Google Cloud data release.

**Motivation:** Most GUI Grounding works use [GUI-Actor-Data](https://huggingface.co/datasets/cckevinn/GUI-Actor-Data) for training, which includes AndroidControl images but **does not include the test set JSON**. Obtaining the test split from the original source requires downloading the full dataset (~47 GB) from Google Cloud, which is cumbersome. This dataset provides the test split JSON files directly so researchers can run evaluations immediately.

**Images:** Screenshots are not included in this repository. Use the images from [cckevinn/GUI-Actor-Data](https://huggingface.co/datasets/cckevinn/GUI-Actor-Data), which covers all splits including the test set.

## Files

| File | Episodes | Steps | Description |
|------|----------|-------|-------------|
| `test-AndroidControl.json` | 1,543 | 8,444 | All action types |
| `test-AndroidControl-click.json` | 1,484 | 5,074 | Click actions only |

---

## Data Format

Both files share the same structure: a **list of episodes**, where each episode is a **list of steps**.

```json
[
  [                          // episode
    {                        // step
      "img_url": "android_control_episode_[27]_0.png",
      "img_size": [1080, 2400],
      "episode_id": 27,
      "goal": "Open the Zoho Meet app, view the scheduled meetings.",
      "instruction": "Open the Zoho Meet app",
      "action": {
        "action_type": "open_app",
        "app_name": "Zoho Meeting"
      }
    },
    ...
  ],
  ...
]
```

### Fields

| Field | Type | Description |
|-------|------|-------------|
| `img_url` | string | Filename of the corresponding screenshot, format: `android_control_episode_[{episode_id}]_{step_idx}.png` |
| `img_size` | [int, int] | Screenshot resolution `[width, height]`, typically `[1080, 2400]` |
| `episode_id` | int | Episode ID from the original AndroidControl dataset |
| `goal` | string | High-level task goal in natural language |
| `instruction` | string | Step-level instruction |
| `action` | object | Ground-truth action (see below) |

### Action Types

| `action_type` | Additional Fields | Description |
|---------------|------------------|-------------|
| `click` | `x`, `y` (normalized 0–1) | Tap on screen coordinates |
| `scroll` | `direction` (`up`/`down`/`left`/`right`) | Scroll gesture |
| `type` | `text` | Type text input |
| `navigate_back` | — | Press back button |
| `navigate_home` | — | Press home button |
| `open_app` | `app_name` | Launch an application |
| `wait` | — | Wait for screen to load |

> `test-AndroidControl-click.json` contains only `click` steps and is intended for point-grounding evaluation.

## Usage

```python
import json

with open("test-AndroidControl.json") as f:
    episodes = json.load(f)

# episodes[i]        → i-th episode (list of steps)
# episodes[i][j]     → j-th step of i-th episode
# episodes[i][j]["img_url"]  → match against GUI-Actor-Data images
```
