Android 17 Beta 4 arrives with post-quantum cryptography and new memory limits

On April 16, Google released Android 17 Beta 4, concluding its beta phase and focusing on app compatibility and platform stability. Developers must finalize updates for Android 17 to avoid delays when the stable version is released. Key behavioral changes for apps targeting Android 17 include: - Large-screen resizability restrictions, preventing apps from opting out of maintaining orientation, resizability, and aspect ratio constraints. - Expanded restrictions on dynamic code loading, requiring native files loaded via System.load() to be read-only. - Certificate Transparency is enabled by default. - Local network access is restricted by default, with a new ACCESSLOCALNETWORK permission for persistent access. - Stricter rules on background audio interactions, including playback and volume change APIs. Android 17 introduces per-app memory limits based on device RAM to target memory leaks and anomalies, with minimal impact expected on app sessions. Developers can check for memory limit impacts via ApplicationExitInfo and utilize profiling tools in Android Studio Panda. An on-device anomaly detection service monitors resource-intensive behaviors and provides profiling artifacts. Additionally, the Android Keystore now supports ML-DSA for quantum-safe signatures, allowing developers to generate keys and create signatures within secure hardware.

Privacy Messenger Session Is Staring Down a 90-Day Countdown to Obscurity

The messaging app Session, which prioritizes user privacy and offers end-to-end encryption without requiring personal information for registration, is facing potential closure and has issued a call for support. The Session Technology Foundation (STF) has received funding to support operations for 90 days but will rely on volunteers after all paid staff have been let go. Development activities have paused due to insufficient funding, affecting the introduction of new features and the resolution of existing bugs. The STF has stated that it needs million to complete ongoing projects and introduce a subscription model to achieve self-sustainability. As of now, 0,000 has been raised towards this goal. Users can contribute at getsession.org/donate.
