Workflow

1. Setup

adb devices                                        # Verify connection
adb shell wm size                                  # Device info
adb shell dumpsys window | grep mCurrentFocus      # Current app package

2. 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
adb shell input swipe 540 500 540 1500 300   # Scroll up
adb shell input swipe 900 1000 100 1000 300  # Swipe left
adb shell input swipe 100 1000 900 1000 300  # Swipe right
adb shell input swipe X Y X Y 1000           # Long press
adb shell input keyevent 4                   # Back
adb shell input keyevent 3                   # Home
adb shell input keyevent 66                  # Enter
adb shell input text "text"                  # Type

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
