JNI를 사용하는 EDK 메서드에서 Const char * 반환

.java 파일에서 내 게임으로 String을 반환하려고하지만 일부 SIG 오류가 발생합니다. 하기 위해JNI를 사용하는 EDK 메서드에서 Const char * 반환

const char* s3eExtensionGetRegisterationID_platform() 

{ 
    JNIEnv* env = s3eEdkJNIGetEnv(); 
    JavaString res((jstring)env->CallObjectMethod(g_Obj, g_s3eExtensionGetRegisterationID); 
    return getCString((jstring)res); 
}

내가해야 할 것 아무것도가 있나요 -

const char* s3eExtentionGetRegisterationID() run_on_os_thread

나는이 같은 JNI 방법을 편집 할 수 s3eExtension_platform.cpp 수정 - 다음과 같은 방법 s4e에 선언 문자열을 가져 오십시오. 내가 점점 오전 오류입니다 -

내가 너무 이러한 방법을 선언 할 필요가 있음을 잊어
