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
