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)
  • Skip encoding and capturing buffered session replay segments while rate-limited, so we don't waste resources on envelopes the transport will drop (#5813)
    • These skipped replays are now reported as ratelimit_backoff discarded events in client reports, so they no longer disappear from drop statistics. One event is recorded per buffer flush rather than per segment.
    • Buffer mode is also kept while rate-limited instead of switching to session mode, so the rolling buffer stays warm and the next error after the rate limit expires can send a complete replay.

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)
