在這里介紹使用Android Studio調(diào)用Bmob SDK，接而實(shí)現(xiàn)Unity與Android通信達(dá)到游戲支付功能

下載Bmob 支付SDK，在這里我使用的是BmobPay_v3.0.3版本，可以到點(diǎn)擊打開鏈接下載最新版本

下載頁面

1.將下載好的Bmob解壓，找到BmobPay_v3.0.3_160621.jar文件，將其拖動到libs文件目錄下，點(diǎn)擊右鍵選擇add in library

2.選擇如下圖的.xml文件添加一行：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

3.在如下圖文件下寫入代碼：

代碼如下：

package com.liujunliang.bmobpay;  
  
import android.support.v7.app.AppCompatActivity;  
import android.os.Bundle;  
import android.view.Menu;  
import android.view.MenuItem;  
  
import com.unity3d.player.UnityPlayer;  
import  com.unity3d.player.UnityPlayerActivity;  
  
import c.b.BP;  
import c.b.PListener;  
  
public class MainActivity extends UnityPlayerActivity  
{  
    @Override  
    protected void onCreate(Bundle savedInstanceState)  
    {  
        super.onCreate(savedInstanceState);  
        //setContentView(R.layout.activity_main);  
  
        //初始化支付  
        BP.init(this,"0e6c7e349cf407d2754b914e1e1bb42e");  
  
    }  
  
    //unity將會調(diào)用addNumber函數(shù)  
    public int addNumber(int a,int b)  
    {  
        //與unity通信，調(diào)用untiy的方法  
        //參數(shù)一：掛件游戲?qū)ο? 
        //參數(shù)二：掛件函數(shù)方法名  
        //參數(shù)三：函數(shù)方法參數(shù)  
        UnityPlayer.UnitySendMessage("Main Camera", "PrintText", "http://www.liujunliang.com.cn");  
  
        return a+b;  
    }  
  
    public void payByZhiFuBao()//發(fā)起支付寶支付  
    {  
        //發(fā)起支付  
        //參數(shù)一：商品名稱  
        //參數(shù)二：商品描述  
        //參數(shù)三：商品價格  
        //參數(shù)四：回調(diào)商品支付狀態(tài)  
        BP.pay("倚天劍", "道具", 0.02, true, new PListener() {  
            @Override  
            public void orderId(String s) {  
  
            }  
  
            @Override  
            public void succeed() {  
                androidSendMessageForZhiFuBao(0, "");  
            }  
  
            @Override  
            public void fail(int i, String s) {  
                androidSendMessageForZhiFuBao(1, s);  
            }  
  
            @Override  
            public void unknow() {  
  
            }  
        });  
    }  
  
    private void androidSendMessageForZhiFuBao(int a,String s)  
    {  
        UnityPlayer.UnitySendMessage("Main Camera","BmobPayByZhiFuBao","支付寶支付:"+a+s);  
    }  
  
  
    public void payByWeiXin()//發(fā)起微信支付  
    {  
        //發(fā)起支付  
        BP.pay("屠龍刀", "道具", 0.02, true, new PListener() {  
            @Override  
            public void orderId(String s) {  
            }  
              @Override  
            public void succeed() {  
                androidSendMessageForWeiXin(0,"");  
            }  
  
            @Override  
            public void fail(int i, String s) {  
                androidSendMessageForWeiXin(1,s);  
            }  
  
            @Override  
            public void unknow() {  
  
            }  
        });  
    }  
  
    private void androidSendMessageForWeiXin(int a,String s)  
    {  
        UnityPlayer.UnitySendMessage("Main Camera","BmobPayByWeiXin","微信支付:"+a+s);  
    }  
  
}  

4.android調(diào)用bmob sdk已經(jīng)簡單完成，接下來開啟unity工程，按上一篇文章運(yùn)行、classed.jar文件替換、如下圖三個文件拷貝到unity中Android目錄下點(diǎn)擊打開鏈接

5.創(chuàng)建C#腳本組件調(diào)用Android工程

代碼如下：

using UnityEngine;  
using System.Collections;  
using UnityEngine.UI;  
  
public class UnityCallAndroid : MonoBehaviour   
{  
     
    public Text show;  
  
    // Use this for initialization  
    void Start ()   
    {  
  
    }  
  
    // Update is called once per frame  
    void Update ()  
    {  
          
    }  
 
    #region 支付寶支付  
    public void OnClickedZhiFuBao()  
    {  
  
        AndroidJavaClass AJC = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");  
          
        AndroidJavaObject AJO = AJC.GetStatic<AndroidJavaObject> ("currentActivity");  
          
        AJO.Call ("payByZhiFuBao");  
    }  
    #endregion  
 
    #region Android工程調(diào)用unity方法  
    public void BmobPayByZhiFuBao(string resultStr)  
    {  
        show.text = resultStr;  
    }  
    #endregion  
 
 
 
    #region 微信支付  
    public void OnClickedWeiXin()  
    {  
          
        AndroidJavaClass AJC = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");  
          
        AndroidJavaObject AJO = AJC.GetStatic<AndroidJavaObject> ("currentActivity");  
          
        AJO.Call ("payByWeiXin");  
    }  
    #endregion  
     
    #region Android工程調(diào)用unity方法  
    public void BmobPayByWeiXin(string resultStr)  
    {  
        show.text = resultStr;  
    }  
    #endregion  
}
