您应该放置以下行:

You should place the line:

long status = JNI_CreateJavaVM(&m_vm,(void **)&env, &vm_args);

在函数内部.
例如

inside a function.
E.g.

JavaVM *m_vm;
JNIEnv* env;
jobject obj;
JavaVMInitArgs vm_args;
long status;

void init()
{
  status = JNI_CreateJavaVM(&m_vm,(void **)&env, &vm_args);
  // other initialization stuff
}
