Android Studio Rabbit 2 Canary 4 fixes a Compose Preview memory leak

StudioModuleClassLoader instances were never released, filling Metaspace until an OutOfMemoryError.

Updated

Android Studio Rabbit 2 Canary 4, released October 8, 2026, fixes a Compose Preview bug in which StudioModuleClassLoader instances were never released, so Metaspace filled until the IDE hit an OutOfMemoryError.

The release notes list these other general fixes:

  • The ACP agent failing to start when the npm registry mirror had not synced the version pinned by the ACP registry (ETARGET).
  • Gradle 9.8.0 reporting Configuration.setVisible() deprecations with AGP 9.4.1.
  • An NPE from PathTracker.
  • KMP Android library resource directories added through sources.res.addStaticSourceDirectory not being recognized by the IDE.
  • The physical device screen mirror showing at a resolution too low to read text.
  • The Pixel Watch companion crashing after emulator pairing.

The notes give an issue number for each fix but no detail on how it was fixed.
