Nov 1, 2025November 2025 focused on strengthening authentication security for the Iterable Android SDK. Delivered a User Authentication Security Enhancement that prevents user-controlled bypass of sensitive methods by introducing a completion handler pattern and validated credential checks. This change reduces risk of credential bypass and improves overall compliance with security standards. The primary code change ties to commit 42b4e114e5720492b7298b42bab2224363a9514a ([SDK-165]/GSRR-709). The work enhances business value by increasing trust in login flows and safeguarding user data. Impact includes lower vulnerability surface, safer release of sensitive features, and a foundation for future security hardening. Technologies demonstrated include Kotlin/Java Android development, security patterns, asynchronous completion handlers, credential validation flows, and code reviews.

Oct 1, 2025October 2025 monthly summary for Iterable/iterable-android-sdk focusing on delivering a more reliable startup experience and robust WebView handling. Key accomplishments include implementing background initialization for the Iterable SDK to avoid ANR and ensure queued API calls execute post-initialization, and fixing a WebView CORS issue for self-hosted fonts by adding a webViewBaseUrl configuration that enables proper resource loading. These changes reduce startup latency, prevent data loss during init, improve in-app messaging reliability, and enhance overall app stability. Technologies demonstrated include Android multithreading, background task orchestration, request queuing, and WebView/CORS configuration.

Aug 1, 2025August 2025 (2025-08): Stability and resilience improvements in encryption handling within the Iterable Android SDK. Fixed a KeyStoreException crash on Nexus 5 by wrapping initialization in try-catch, disabling encryption, and falling back to plaintext storage. Added a unit test to validate the failure path and ensure continued app functionality.

Jun 1, 2025June 2025 monthly summary: Delivered a stability fix for Android SDK token refresh across app lifecycle in Iterable/iterable-android-sdk. The change ensures the token refresh timer is cleared when the app goes to background, re-enabled on foreground, and that a token refresh is not triggered while authentication is pending. Added automated tests to cover background/foreground refresh scenarios. This work reduces background refresh churn, eliminates race conditions during lifecycle transitions, and improves session continuity for users. The fix is tracked under MOB-11508 and committed as 6645080d98b1b790bf10467230dfc338be67ccf3.
