Unity之SDK接入（Unity与Android通信）

1.eclipse中新建Android工程，添加MainActivity.java代码：

package com.example.test;

import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;

import android.os.Bundle;

public class MainActivity extends UnityPlayerActivity  {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
    public void Send() {
        UnityPlayer.UnitySendMessage("aaa", "AndroidCallBack", "okokoko");
    }
}

MainActivity

从eclipse中导出jar包

2.Unity中，新建工程，

编写EclipseCall.cs代码如下：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System;

public class EclipseCall : MonoBehaviour
{
    private AndroidJavaClass jc;
    private AndroidJavaObject jo;
    private Text text;
    private Button btn;

    //单例模式
    private static EclipseCall _instance;
    public static EclipseCall Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance = new EclipseCall();
            }
            return _instance;
        }
    }

    void Start()
    {
        text = GameObject.Find("aaa").GetComponent<Text>();
        btn = GameObject.Find("Button").GetComponent<Button>();
        this.name = "aaa";

        _instance = this;
        jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
    }

    public void ClickBtn()
    {
        jo.Call("Send");
    }

    public void AndroidCallBack(String str)
    {
        text.text = str;
    }
}

EclipseCall

将eclipse中导出的jar包拖进libs文件中

打包：

运行，点击后的UI：
