A weird error in an implementation of loadDex in android NDK - 


char* (*loaddex) (char * dexpath, char * odexpath,int flag) = null;  jniexport jint jni_onload(javavm* vm, void* reserved) {     char* (*loaddex) (char *, char *,int) = null;      logd("jni_onload!");      void *ldvm = (void*) dlopen("/system/lib/libdvm.so", rtld_lazy);      if(ldvm == null)      {         logd("error : %s",dlerror());         //is art         void *ldvm = (void*) dlopen("/system/lib/libart.so", rtld_lazy);      }     loaddex = (char* (*) (char *, char *,int)) dlsym (ldvm, "loaddex");  void *venv;      if ((*vm)->getenv(vm, (void**) &venv, jni_version_1_4) != jni_ok)     {            return -1;      }      return jni_version_1_4; }

i use dlsym() function in order pointer of loaddex() returns 0. here can teach me how exact pointer?

thanks in advance!

loaddex private api of dalvik , doesn't exist in art. sort of thing should done in java.
