Android Emulator QA

Validate Android app flows in an emulator using adb for launch, input, UI-tree inspection, screenshots, and logs.

When to use

  • QA a feature flow in an Android emulator.
  • Reproduce UI bugs by driving navigation with adb input events.
  • Capture screenshots and logcat output while testing.

adb control commands

  • Tap (use UI tree-derived coordinates):
    • adb -s <serial> shell input tap <x> <y>
  • Swipe:
    • adb -s <serial> shell input swipe <x1> <y1> <x2> <y2>
    • Avoid edges (start ~150-200 px from left/right) to reduce accidental back gestures.
  • Text:
    • adb -s <serial> shell input text "hello"
  • Back:
    • adb -s <serial> shell input keyevent 4
  • UI tree dump:
    • adb -s <serial> exec-out uiautomator dump /dev/tty

Coordinate picking (UI tree only)

Always compute tap coordinates from the UI tree, not screenshots.

  1. Dump the UI tree to a step-specific file:
    • adb -s <serial> exec-out uiautomator dump /dev/tty > /tmp/ui-settings.xml
  2. Find the target node and derive center coordinates (x y) from bounds:
    • Bounds format: bounds="[x1,y1][x2,y2]"
    • Helper script:
    • python3 <path-to-skill>/scripts/ui_pick.py /tmp/ui-settings.xml "Settings"
  3. If the node is missing and there are scrollable elements:
    • swipe, re-dump, and re-search at least once before concluding the target is missing.
  4. Tap the center:
    • adb -s <serial> shell input tap <x> <y>

UI tree skeleton (helper)

Use this helper to create a compact, readable overview before inspecting full XML.

  1. Dump full UI tree:
    • adb -s <serial> exec-out uiautomator dump /dev/tty > /tmp/ui-full.xml
  2. Generate summary:
    • python3 <path-to-skill>/scripts/ui_tree_summarize.py /tmp/ui-full.xml /tmp/ui-summary.txt
  3. Review /tmp/ui-summary.txt to choose likely targets, then compute exact bounds from full XML.

Logs (logcat)

  1. Clear logs:
    • adb -s <serial> logcat -c
  2. Stream app process logs:
    • Resolve pid: adb -s <serial> shell pidof -s <package>
    • Stream: adb -s <serial> logcat --pid <pid>
  3. Crash buffer only:
    • adb -s <serial> logcat -b crash
  4. Save logs:
    • adb -s <serial> logcat -d > /tmp/logcat.txt

Package shortcuts

  • List installed packages:
    • adb -s <serial> shell pm list packages
  • Filter to your namespace:
    • adb -s <serial> shell pm list packages | rg <company_or_app_id>
  • Confirm the activity resolves before launching:
    • adb -s <serial> shell cmd package resolve-activity --brief <package>
