The root cause of the SIGBUS (alignment fault) crash was casting jmethodID values to function pointers and invoking them directly. jmethodID is an opaque JNI type that must only be used via CallVoidMethod/CallObjectMethod etc. Calling it as a function pointer dereferences garbage memory, causing SIGBUS at address 0xb1. Changes: - Replace function pointer typedefs (output_callback_t etc.) with a struct storing JNIEnv + callback global ref + jmethodIDs - All callbacks now go through CallVoidMethod(env, ref, mid, ...) - Remove getTestProgress() (never used, unused start_time workaround) - Fix Kotlin arg cast: List<String> -> toTypedArray() (ClassCastException) - Update UI default server to speedtest.uztelecom.uz
