--- name: adb-device-testing description: Use when testing Android apps on ADB-connected devices/emulators - UI automation, screenshots, location spoofing, navigation, app management. Triggers on ADB, emulator, Android testing, location mock, UI test, screenshot walkthrough. --- # ADB Device Testing ## Quick Reference ### Screenshots (Multimodal) ```bash adb exec-out screencap -p > /tmp/screen.png ``` Then use Read tool to VIEW the image. ### Location Spoofing (Emulator Only) ```bash # longitude, latitude adb emu geo fix -74.006 40.7128 # NYC adb emu geo fix 2.3522 48.8566 # Paris ``` IMPORTANT: for getting proper component location always use Element Discovery (uiautomator) ### Navigation | Action | Command | |--------|---------| | Tap | `adb shell input tap ` | | Scroll up | `adb shell input swipe 500 1500 500 500 300` | | Scroll down | `adb shell input swipe 500 500 500 1500 300` | | Back | `adb shell input keyevent KEYCODE_BACK` | | Home | `adb shell input keyevent KEYCODE_HOME` | | Text | `adb shell input text "hello"` | | Long press | `adb shell input swipe 500 500 500 500 1000` | ### Element Discovery (uiautomator) ```bash adb shell uiautomator dump /sdcard/ui.xml adb pull /sdcard/ui.xml /tmp/ui.xml # Parse bounds="[x1,y1][x2,y2]" → tap center ``` ### App Management ```bash adb install -r app.apk adb shell am start -n / adb shell am force-stop adb shell pm clear ``` ## Testing Workflow Copy this checklist: ``` Progress: - [ ] Verify device connected (adb devices) - [ ] Setup: install app, clear state, set location - [ ] Screenshot initial state - [ ] Execute test actions (tap/swipe) - [ ] Wait after each action (sleep 0.5-1) - [ ] Screenshot and verify each step - [ ] Report results with evidence ``` ### Step-by-Step **1. Verify Connection** ```bash adb devices -l ``` No devices? Check USB debugging enabled, emulator running. **2. Setup** ```bash adb install -r /path/to/app.apk adb shell pm clear adb emu geo fix # emulator only adb shell am start -n / sleep 2 ``` **3. Test Loop** ```bash # Screenshot adb exec-out screencap -p > /tmp/screen_01.png # View screenshot with Read tool to analyze UI # Identify tap coordinates from UI or uiautomator dump adb shell input tap sleep 1 # Screenshot to verify adb exec-out screencap -p > /tmp/screen_02.png ``` **4. Element Finding** ```bash adb shell uiautomator dump /sdcard/ui.xml adb pull /sdcard/ui.xml /tmp/ui.xml # Grep for element: bounds="[100,200][300,400]" # Tap center: (100+300)/2=200, (200+400)/2=300 adb shell input tap 200 300 ``` ## Critical Rules 1. **Always wait** after UI actions before screenshots (`sleep 0.5-1`) 2. **View screenshots** with Read tool - don't just capture 3. **Use absolute paths** for screenshot files 4. **Location spoofing = emulator only** - physical devices need mock apps 5. **Parse uiautomator XML** for precise element coordinates ## Advanced Features **Device info:** ```bash adb shell wm size # resolution adb shell getprop ro.product.model ``` **Logs:** ```bash adb logcat -d | grep ``` **Screen recording:** ```bash adb shell screenrecord /sdcard/demo.mp4 # Ctrl+C to stop adb pull /sdcard/demo.mp4 /tmp/ ``` **For complex testing scenarios**: See [ADVANCED.md](ADVANCED.md) --- Source attribution: hanibalsk Original project: https://github.com/hanibalsk/phone-manager/blob/a441ef9ef6b3abe0a0ae263726467cbb8501a47d/.claude/skills/adb-device-testing/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Dave AI. ## Upstream license notice MIT License Copyright (c) 2025 Phone Manager Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
