EventBus (Asamm Fork)

Fork of greenrobot/EventBus 3.3.1 with critical bug fixes for modern Android (API 35+, AndroidX, R8 full mode).

The upstream project is no longer actively maintained (last release Feb 2024, 147 open issues). This fork applies minimal, targeted patches to keep EventBus working with current Android toolchains.

Changes from upstream 3.3.1

SubscriberMethodFinder — fix NoClassDefFoundError during register():

• Check @Subscribe annotation before getParameterTypes() to avoid unnecessary class loading for non-subscriber methods (based on PR #560)
• Catch NoClassDefFoundError in getAnnotation() for methods referencing classes unavailable on the current API level (based on PR #293)
• Catch NoClassDefFoundError in getParameterTypes() for methods with parameter types from newer API levels (e.g. PictureInPictureUiState on API < 35, ComponentCaller on API < 35). See issue #737, issue #726
• Add null-check in moveToSuperclass() after getSuperclass() (based on PR #560)
