To make it easier to be used in e.g. Desktop environments, we now additionally added it as an option on SentryOptions that can also be set via `sentry.properties`. - If both the param on `Sentry.init` and the option are set, the option will win. By default the option is set to `null` meaning whatever is passed to `Sentry.init` takes effect. - Lazy uuid generation for SentryId and SpanId ([#3770](https://github.com/getsentry/sentry-java/pull/3770)) +- Faster generation of Sentry and Span IDs ([#3818](https://github.com/getsentry/sentry-java/pull/3818)) + - Uses faster implementation to convert UUID to SentryID String + - Uses faster Random implementation to generate UUIDs - Use a separate `Random` instance per thread to improve SDK performance ([#3835](https://github.com/getsentry/sentry-java/pull/3835)) - Android 15: Add support for 16KB page sizes ([#3851](https://github.com/getsentry/sentry-java/pull/3851)) - See https://developer.android.com/guide/practices/page-sizes for more details diff --git a/sentry-android-core/src/main/java/io/sentry/android/core/AndroidProfiler.java b/sentry-android-core/src/main/java/io/sentry/android/core/AndroidProfiler.java index f10dbef109..c1ae1237e2 100644 --- a/sentry-android-core/src/main/java/io/sentry/android/core/AndroidProfiler.java +++ b/sentry-android-core/src/main/java/io/sentry/android/core/AndroidProfiler.java @@ -12,6 +12,7 @@ import io.sentry.MemoryCollectionData;
