Workflow
1. Setup
adb devices # Verify connection
adb shell wm size # Device info
adb shell dumpsys window | grep mCurrentFocus # Current app package2. Main Loop (repeat for each screen)
# A) Screenshot
adb exec-out screencap -p > {app}_{seq:02d}.png
# B) Analyze screenshot visually (Read tool)
# C) UI dump for coordinates
adb shell uiautomator dump /sdcard/ui.xml
adb shell cat /sdcard/ui.xml
# D) Find bounds: [left,top][right,bottom]
# E) Calculate center: x=(left+right)/2, y=(top+bottom)/2
# F) Tap
adb shell input tap X Y
# G) Repeat from A)3. Navigation Commands
adb shell input tap X Y # Tap
adb shell input swipe 540 1500 540 500 300 # Scroll down

Troubleshooting
# No device
adb kill-server && adb start-server && adb devices
# UI dump fail
adb shell uiautomator dump /data/local/tmp/ui.xml
adb shell cat /data/local/tmp/ui.xml
# Black screenshot
adb shell screencap -p /sdcard/s.png && adb pull /sdcard/s.png
# Tap not working - recalculate coordinates from fresh UI dump,
# verify clickable="true", add sleep 1 before tap
