Summary of Changes

Hello @john-mikhail, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on updating the Windows Analytics DLL to its latest version, which includes a new naming convention for the DLL. A significant new feature is the introduction of an NotifyAppLifecycleChange API, allowing the application to explicitly inform the Analytics SDK about its lifecycle state, crucial for ensuring data is properly uploaded before termination. Additionally, the update provides a mechanism for setting a custom log callback, enhancing debuggability and integration, and introduces an option to specify a custom data storage directory.

Highlights

• Analytics DLL Update: The Windows Analytics DLL has been updated to its latest version, which includes a new filename and an updated SHA256 hash for verification.
• App Lifecycle Management: A new NotifyAppLifecycleChange function has been introduced, allowing the SDK to be explicitly informed about the application's lifecycle state, particularly for termination events to ensure pending data is uploaded.
• Logging Callback: Functionality to set a custom log callback has been added, enabling applications to intercept and handle SDK log messages for better debuggability and integration.
• DLL Naming Standardization: The analytics DLL filename has been standardized from analytics_win.dll to google_analytics.dll across the codebase for consistency.
• Improved API Return Types: Several Insert functions in the C API now return a bool to indicate success or failure, improving error handling capabilities.
• Configurable Data Directory: The GoogleAnalytics_Options now includes an app_data_directory field, allowing users to specify a custom path for SDK data storage.
• New Event and Event Parameter Updates: A new event kEventPublicInAppPurchase has been added, and the parameter requirements for kEventScreenView have been updated, making kParameterScreenClass optional.

Code Review

This pull request updates the analytics Windows DLL to its latest version, which introduces several API changes. A new function, NotifyAppLifecycleChange, has been added to handle app lifecycle events, and this is now correctly called during termination to ensure analytics data is flushed. The codebase has been updated to reflect other API changes, such as modified function signatures and new initialization options. The integration tests have also been updated to cover the new functionality. My review includes a couple of minor suggestions to improve documentation and code readability.
