Task/Issue URL: https://app.asana.com/1/137249556945/project/608920331025315/task/1212017534631022?focus=true

Description

Add pixel for when timeouts happen in app initialisation paths:

• when a pre-ATB-initialization plugin times out
• when the app times out waiting for a referrer

Steps to test this PR

Add logcat filter: message~:message~:"Waiting for referrer|Initializing ATB|Variants update|Initialized ATB|ull referrer stri|Result determined|for referrer|posting initial|WebView passkey support|wv|timed out|AtbInitializer|Pixel interceptor: .*atb_pre_initializer_plugin_timeout|Pixel interceptor: .*timeout_atb_pre_initializer_plugin|interceptor.*timeout_waiting_for_referrer"

Happy path

• Fresh install playDebug variant and launch the app
• Verify you see logs for:

AtbInitializer: About to initialize ATB; running 3 pre ATB initialization plugins
AtbInitializer: Running pre-ATB init plugin [ReinstallAtbListener]
AtbInitializer: Running pre-ATB init plugin [AuraExperimentManager]
AtbInitializer: Running pre-ATB init plugin [PlayStoreAppReferrerStateListener]

Force timeout in app referrer

• Apply patch from Patch: Referrer timeout
• Fresh install playDebug variant and launch app
• Verify you see logs for LaunchViewModel timed out waiting for referrer
• Verify you see pixel in logs for timeout_waiting_for_referrer

Force timeout in pre-ATB-init plugin

• Delete all local changes
• Apply patch from Patch: pre-ATB init plugin timeout
• Fresh install and launch app
• Verify you see pixel in logs for timeout_atb_pre_initializer_plugin with param plugin=ReinstallAtbListener

---

Note

Emit pixels when app referrer wait or pre-ATB initialization plugins time out, with wiring, parameter cleaning, and tests.

• Telemetry/Pixels:
  • Add timeout_waiting_for_referrer and timeout_atb_pre_initializer_plugin (with plugin param) in PixelDefinitions/.../app_initialization_timeout.json5.
  • Introduce AtbInitializationPluginPixelSender and send ATB_PRE_INITIALIZER_PLUGIN_TIMEOUT from AtbInitializer on plugin timeout.
  • LaunchViewModel fires AppPixelName.TIMEOUT_WAITING_FOR_APP_REFERRER on referrer wait timeout.
• Interceptors:
  • Update PixelParamRemovalInterceptor to remove ATB/app version where required, including for TIMEOUT_WAITING_FOR_APP_REFERRER and ATB_PRE_INITIALIZER_PLUGIN_TIMEOUT.
• DI:
  • Inject AtbInitializationPluginPixelSender into AtbInitializer; update StubStatisticsModule accordingly.
• Tests:
  • Add/extend tests for AtbInitializer timeout behavior and pixel emission; add LaunchViewModel test asserting referrer-timeout pixel.
