有人可以给出Hello World的简单RMI回调示例吗？我一直在努力研究它,但我似乎无法找到一个我理解的.我不明白回调是什么/做什么.

接口

package example.hello;

import java.rmi.Remote;
import java.rmi.RemoteException;

}

客户

package example.hello;

import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;

public class Client {

    private Client(){}

    public static void main(String[] args){

        String host = (args.length < 1) ? null : args[0];

        try{
            Registry registry = LocateRegistry.getRegistry(host);
            Hello stub = (Hello) registry.lookup("Hello");
            String response = stub.sayHello();
            System.out.println("response: " + response);
        } catch (Exception e) {
            System.err.println("Client exception: " + e.toString());
            e.printStackTrace(); …

adb shell dumsys meminfo 返回的内存是以 kB 为单位还是以 KB 为单位？

在哪里：

kB = 1000 bytes    
KB = 1024 bytes
