Summary

The docs said that ActivateApp() with automatic logging off still logs app opens. It does not with the bundled facebook-core 19.0.0. A runtime check showed only the install ping and no fb_mobile_activate_app, and the bytecode confirms it.

Bytecode evidence (javap on the pinned facebook-core-19.0.0.aar, SHA-256 22782e58…2dcab):

• SessionLogger.logActivateApp / logDeactivateApp log through InternalAppEventsLogger.logEvent(String, Bundle) / logEvent(String, double, Bundle).
• Both methods start with FacebookSdk.getAutoLogAppEventsEnabled() followed by ifeq → return. Automatic events are dropped while the flag is off, even when ActivateApp() started tracking.
• AppEventsLoggerImpl.activateApp calls publishInstallAsync and then ActivityLifecycleTracker.startTracking. The install ping does not depend on the flag. No other class calls publishInstallAsync, so automatic logging alone never sends the install ping.
• UserSettingsManager.checkAutoLogAppEventsEnabled returns the local value AND the cached server value auto_log_app_events_enabled. A local false always wins, and a server-side disable overrides a local true.
• FacebookSdk.setAutoLogAppEventsEnabled writes the value to SharedPreferences, where it persists, and starts tracking when the value is true.
• AutomaticAnalyticsLogger.isImplicitPurchaseLoggingEnabled requires both automatic logging and the dashboard IAP setting.

Changes

• Docs/Integration.md:
  • corrects the manifest switch row;
  • documents the supported recipe: SetAutoLogAppEventsEnabled(true) plus ActivateApp() after consent, with automatic in-app purchase and subscription logging turned off on the App Dashboard Android card when a server reports purchases;
  • notes that the flag persists across launches and that Events Manager must not disable automatic SDK logging;
  • corrects the withdrawal note: turning the flag off stops automatic events at once, while tracking and flushing continue;
  • corrects the double-counting section.
• FacebookAppEvents.cs XML docs: the class remarks, SetAutoLogAppEventsEnabled and ActivateApp, corrected the same way.
• Sample: GrantConsent enables automatic logging, and the README is updated to match.

No API or package content change. The nuget readme carries no such claim. The XML docs ship in the package, so the next release will carry the fix.
