Camera and Event Dispatcher Error on Android Devices

[armanhossiny]

Crash Report:

hi,

I have encountered a crash issue in my application related to Axmol. The crash logs suggest that the issue might be stemming from ax::Camera::initDefault() and ax::EventDispatcher::dispatchEvent(). The SIGSEGV/SEGV_MAPERR error indicates that the application is accessing invalid memory addresses.

Crash Details:

OS: Android 14
Device: Redmi Fire 4.19.191
CPU: arm64
AXMol Version: a4a7564
Description of the Issue:

The ax::Camera::initDefault() crash might be related to incorrect camera resource management.
The ax::EventDispatcher::dispatchEvent() crash appears to be related to incorrect EventListener management or incorrect event dispatching.
