Features

• Use Android's ProfilingManager (Perfetto) for continuous profiling on API 35+ devices (#5251)
  • On API 35+ devices, continuous profiling now automatically uses Android's system ProfilingManager with Perfetto-based stack sampling, providing lower-overhead and more accurate profiles. No configuration change is required.
  • Devices below API 35 keep using the legacy Debug-based profiler.
  • Added an enableLegacyProfiling option (default true) to disable the legacy Debug-based profiler. Setting it to false disables continuous profiling on API < 35 devices as well as transaction-based profiling (profilesSampleRate/profilesSampler) on all devices, since transaction-based profiling is not supported by Perfetto.
  • It can also be configured via the io.sentry.profiling.enable-legacy-profiling manifest flag.
  • See the Android profiling docs for details.

Behavioral Changes

• The outbox and cache directories are no longer created by Sentry.init (#5792)
  • They are now created lazily by whichever component first writes into them, off the init thread. As a result, the directories at SentryOptions.getOutboxPath() and SentryOptions.getCacheDirPath() are not guaranteed to exist once Sentry.init returns.
  • If you write envelopes into the outbox path yourself instead of going through the SDK — as hybrid SDKs do for captureEnvelope — create the directory first, e.g. new File(outboxPath).mkdirs().

Improvements

• Skip building Android manifest metadata debug log messages when debug logging is disabled, reducing allocations during SDK init (#5790)

Fixes

• Use the original app build's ProGuard UUID for ANR profile chunks (#5852)
• Fix potential ANR/deadlock in Session Replay when checkCanRecord runs on the replay executor thread (#5837)
• Prevent concurrent PixelCopy access during Session Replay masking and bitmap cleanup (#5808)
• Release MediaMuxer when the replay video encoder fails to start to avoid a resource leak (#5607)
• Set the correct platform (android instead of java) on ANR profile chunks so they are billed as UI Profile Hours rather than Continuous Profile Hours (#5836)

Performance

• Create the outbox and cache directories lazily in their consumers instead of during SDK init, moving the mkdirs() calls off the init (main) thread (#5792)
• Reduce the number of SDK threads: LifecycleWatcher now schedules the session-end task on the shared timer executor instead of creating a dedicated java.util.Timer thread (#5819)
• Reduce the number of SDK threads: RateLimiter now schedules its rate-limit-lifted notifications on the shared timer executor instead of creating a dedicated java.util.Timer thread (#5814)
• Speed up deserialization of arbitrary JSON objects by typing numbers without throwing exceptions (#5783)

Dependencies

• Bump Native SDK from v0.15.4 to v0.16.0 (#5845)
