Android Driver & Architecture (UIAutomator2)
* Appium 2.x modularity on Android: server vs driver (`appium driver install uiautomator2`) vs plugins. * Session lifecycle on Android: create → use → delete; driver startup logs; retryability. * UIAutomator2 under the hood: UiAutomation, instrumentation, app under test vs test app. * Required environment: Java, Android SDK/Platform Tools, ANDROID\_HOME/PATH sanity; `appium-doctor`. * Security & exposure: binding host/ports, allowing CORS, limiting external access. * Error taxonomy specific to UIAutomator2: `uiautomator2 server not installed`, `no such driver`, activity resolve failures.
Android Capabilities (W3C) & Driver Selection
* Core caps: `platformName=Android`, `automationName=UiAutomator2`, `deviceName`, `udid` (real devices), `app`/`appPackage`+`appActivity`. * Stability caps: `appWaitActivity`, `appWaitForLaunch`, `appWaitDuration`, `adbExecTimeout`, `newCommandTimeout`. * Reset behavior: `noReset`, `fullReset`, `dontStopAppOnReset`, `skipDeviceInitialization`, `skipServerInstallation`. * Permissions & locale caps: `autoGrantPermissions`, `language`, `locale`, `unicodeKeyboard`, `resetKeyboard`. * Hybrid/WebView caps: `chromedriverExecutable`, `chromedriverExecutableDir`, automatic matching strategy. * Parallelism caps: `systemPort`, `chromeDriverPort` – avoiding port collisions.
App Launch, Activities & Intents
* Discovering main activity: `adb shell dumpsys package`, `aapt dump badging`, logcat hints. * Launch/await: `appActivity` vs `appWaitActivity`, handling splash/transition activities. * Deep-linking via intents: `adb shell am start -W -a android.intent.action.VIEW -d <uri> <package>`. * Starting specific activities during a session (`driver.start_activity`), passing intent extras. * Foreground/background flows: `runAppInBackground`, `activateApp`, `terminateApp`, `resetApp`. * Handling `Activity not started` / `SecurityException` errors.
Locators & Android UI Semantics
* Stable selectors: `resource-id`, `content-desc` (accessibility), `className`, text vs index trade-offs. * AndroidUIAutomator strategy: `ByAndroidUIAutomator('new UiSelector()...')`, predicates, regex, `UiScrollable`. * Lists & grids: RecyclerView patterns, stable anchors inside dynamic lists. * Toasts & transient UI: locating toasts with `//android.widget.Toast` constraints and timing. * Image locators (as last resort): accuracy vs flakiness considerations. * Validation workflow with Appium Inspector: hierarchy, attributes, trial locators.
Synchronization & Stability (Android specifics)
* Implicit vs explicit waits on Android; recommended defaults. * Waiting for activities, toasts, transitions, and network-driven content. * Handling animations: Developer options (disable), app test flags, wait for idle. * Idempotent actions on flaky screens; verifying state before action. * Avoiding `StaleElement`/`Element not interactable` on native views; re-query patterns.
Gestures & Device Interactions (W3C Actions)
* Viewport-relative swipes/scrolls using W3C Actions; percent-based math from window size. * Long press, drag-and-drop sequences; verifying drop targets. * Multi-touch considerations; pinch/zoom where applicable. * Hardware buttons & key events: BACK, HOME, APP\_SWITCH via `pressKeyCode`/`keyevent`. * System UI boundaries: notification shade constraints, quick settings edge cases.
WebViews & Hybrid (Chromium on Android)
* Enabling WebView debugging in app (`setWebContentsDebuggingEnabled(true)`). * Context switching: `NATIVE_APP` ↔ `WEBVIEW_<pkg>`; listing contexts and readiness checks. * Chromedriver version matching strategies; common mismatch errors & fixes. * CSS/XPath usage in WEBVIEW; switching back to NATIVE safely. * Multiple WebViews & iframes; selecting the right context/target.
Permissions, Notifications & System Dialogs
* Runtime permission model (Android 6+): auto-grant vs manual handling. * Handling one-time/while-using prompts; revoking & re-granting for tests. * Interacting with system dialogs (location, camera, storage) reliably. * Notifications constraints: reading vs interacting; when to stub/marshal notifications in app.
Data, Storage & File Operations
* Pushing/pulling files: `driver.push_file` / `pull_file` vs `adb push/pull`. * Media injection for camera/gallery tests; dealing with scoped storage (Android 10+). * Clearing app data vs selective cleanup; caches and databases. * Test data setup for repeatability; on-device folders and permissions.
Debugging, Logs & Diagnostics
* Server logs (debug) vs client logs; mapping failing commands. * `adb logcat` essentials: filtering by tag/package; capturing around failures. * Useful `adb` diagnostics: `bugreport`, `dumpsys activity/top`, `pm list packages`, `settings get`. * Capturing evidence: screenshots, screen recordings, page source dumps. * Minimal reproducibles: isolating a failing step/activity.
Parallelism, Emulators/Real Devices & Infrastructure
* Multi-device execution: unique `udid`, `systemPort`, `chromeDriverPort`, tmp paths. * Emulator vs real device differences: input latency, sensors, OEM skins. * OEM/OS version fragmentation: stabilizing selectors across API levels. * Grid and device farm setup (concepts): node caps, routing, environment parity. * Resource contention: USB stability, adb server restarts, `adb kill-server` pitfalls.
Build, Signing & App Artifacts
* APK vs AAB for testing; using universal APKs / split APKs. * Debug vs release builds; signing keys, `android:debuggable`. * App install/uninstall flows via Appium; install times & `adbExecTimeout`. * Version pinning for stable runs; app versioning in CI. * Discovering/validating `appPackage`/`appActivity` accurately.
CI/CD, Device Clouds & Reporting (Android)
* Gradle tasks for packaging test apps & AUT; caching SDK/platform tools. * Cloud capabilities (generalized): uploading app, selecting devices/API levels, video/screenshots/logs. * Retry/quarantine strategies tuned for Android flakiness signatures. * Artifacts: logcat per device, server/client logs, video, screenshots; naming conventions. * Security of secrets (keystores, service creds) and path management.
Advanced Android Features & System Controls
* Deep links & App Links verification; intent extras for state setup. * Network conditioning via `adb shell svc` (data/wifi), airplane mode constraints. * Geolocation mocking; mock providers; granting `android.permission.ACCESS_MOCK_LOCATION`. * Biometrics simulation approaches (device/emulator), lock screen and authentication flows. * Locale/language switching mid-run; right-to-left layout checks.
Troubleshooting Common Android Failures
* `Activity not started/does not exist`, mis-set `appPackage/appActivity`. * Chromedriver mismatch, WEBVIEW not listed; enabling WebView debug. * `NoSuchElement` vs timing/layout issues; distinguishing root causes. * `adbExecTimeout`, instrumentation crashes, UiAutomator2 server install loops. * Flaky RecyclerView interactions; stabilizing through anchors and waits.
