# Android UI Verification Skill This skill provides a systematic approach to testing React Native applications on an Android emulator using ADB commands. It allows for autonomous interaction, state verification, and visual regression checking. ## When to Use - Verifying UI changes in React Native or Native Android apps. - Autonomous debugging of layout issues or interaction bugs. - Ensuring feature functionality when manual testing is too slow. - Capturing automated screenshots for PR documentation. ## 🛠 Prerequisites - Android Emulator running. - `adb` installed and in PATH. - Application in debug mode for logcat access. ## 🚀 Workflow ### 1. Device Calibration Before interacting, always verify the screen resolution to ensure tap coordinates are accurate. ```bash adb shell wm size ``` *Note: Layouts are often scaled. Use the physical size returned as the base for coordinate calculations.* ### 2. UI Inspection (State Discovery) Use the `uiautomator` dump to find the exact bounds of UI elements (buttons, inputs). ```bash adb shell uiautomator dump /sdcard/view.xml && adb pull /sdcard/view.xml ./artifacts/view.xml ``` Search the `view.xml` for `text`, `content-desc`, or `resource-id`. The `bounds` attribute `[x1,y1][x2,y2]` defines the clickable area. ### 3. Interaction Commands - **Tap**: `adb shell input tap <x> <y>` (Use the center of the element bounds). - **Swipe**: `adb shell input swipe <x1> <y1> <x2> <y2> <duration_ms>` (Used for scrolling). - **Text Input**: `a...
