本文主要是介绍Unity接入GooglePlay内购V4 V5 V6(源生Android方式)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
20230825更新
因为谷歌新政策要求，目前需要支持V5 V6，更新也很简单，将下面的改成5.0或6.0的aar即可
implementation("com.android.billingclient:billing:4.0.0")
改成
implementation("com.android.billingclient:billing:5.0.0")
或
implementation("com.android.billingclient:billing:6.0.0")
代码都是兼容的，亲测有效
-------------------------------------------------------------------
Unity接GooglePlay In-App Billing坑还是蛮多的，各种坑。
接的方式目前来看有三种：
- 采用Unity IAP插件，开启Unity的IAP Service
- 采用Android源生接入，在Android Studio接入，然后打包出jar或aar放到Unity项目，使用Unity调用
- 打包出Android工程，在Android工程中接入
这次介绍的是第二种，使用安卓源生方式接入，因为该方式一劳永逸，新项目可以很快就完成接入。
为什么不用第一种呢？直接导入IAP插件，然后设置参数，就可以很快实现了，该方式可以直接参考google文档。
第一种IAP插件的缺点：
虽然该方式只需要导入插件，然后进行一些参数的设置，但是此方式特别麻烦的一点是需要在Unity中开启Service，但是开启后又得填一大堆信息，巨麻烦无比，而且Unity的网络简直不能看，要么是打不开，要么是卡半死，而且网站老变，以及没有完整的文档。这些都是很恶心人的事情，甚至还要创建组织啥的，反正谁用谁恶心。

正式接入
接入之前需要的储备知识是：Unity如何与Android交互
准备jar和aar
我们的目标是导出自己封装的jar（里面封装了接口供Unity调用，也就是桥接层），以及找到谷歌官方提供的Billing V4插件(aar)。
因为从2021.8.2起，谷歌要求必须接入V3版以上的插件。所以我们这次干脆接了最新的V4.
接入文档可以参考指南：从 AIDL 迁移到 Google Play 结算库的迁移指南
获取aar文件
- 打开Android Studio，创建一个工程
- 创建一个Module，创建完如下（Module要选择Library）
- 打开build.gradle，修改导出为Library，在dependencies中添加依赖，并同步。
implementation("com.android.billingclient:billing:4.0.0") 注意：plugins这边要改为'com.android.library'，导出才会是aar，否则是apk.plugins {id 'com.android.library' }android {compileSdkVersion 30defaultConfig {//applicationId "com.egogame.iapforgoogleplay"minSdkVersion 19targetSdkVersion 30versionCode 1versionName "1.0"testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"}buildTypes {release {minifyEnabled falseproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'}}compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8} }dependencies {implementation 'androidx.appcompat:appcompat:1.3.0'implementation 'com.google.android.material:material:1.3.0'implementation 'org.jetbrains:annotations:15.0'testImplementation 'junit:junit:4.+'androidTestImplementation 'androidx.test.ext:junit:1.1.2'androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'implementation("com.android.billingclient:billing:4.0.0") } - 同步完成后，在gradle缓存路径下找到谷歌官方提供的.aar文件，复制到Unity工程Assets/Plugins/Android目录下，待用
文件路径：C:\Users\xxx\.gradle\caches\modules-2\files-2.1\com.android.billingclient\billing\4.0.0\31aa58e2d4286f6b96480764e7a84d5de9935f02
打包jar
- 创建BaseMainActivity.java类，该类创建了一些供Unity调用的接口格式。

- 我们将aar改为rar格式，然后用压缩软件打开，取出里面的classes.jar，我们只需要该jar即可，该jar是我们封装好的接口，后续有用，为了方便认，我将名字改为IAPForGooglePlay.jar
- 将jar放置到Unity工程下，Assets/Plugins/Android目录下，该目录下文件如下：
注意：jar要放在Android目录下，而不是Android/libs目录下，经试验放libs下会识别不到
- Android这边的工作就结束了，后面我们来写Unity这边的代码
编写Unity接口
- 创建类GooglePlay_IAPBridge，编写调用Android我们封装好的jar里的接口的桥接类
这里面我们直接 javaObject = new AndroidJavaObject("com.egogame.MainActivity");实例化我们jar封装好的类，即可直接调用public方法。请注意：因为Android和Unity线程不一样，所以jar处理时需要规避线程的同步性。#if UNITY_ANDROID using System; using UnityEngine; using System.Collections; using System.Collections.Generic; using Newtonsoft.Json;public class GooglePlay_IAPBridge{class BuyProductData{public string productId;public bool isConsumable;}private AndroidJavaObject javaObject;private GooglePlay_IAPBridge() {if (Application.platform != RuntimePlatform.Android)return;javaObject = new AndroidJavaObject("com.egogame.MainActivity");}private volatile static GooglePlay_IAPBridge _instance = null;private static readonly object lockHelper = new object();public static GooglePlay_IAPBridge getInstance(){if(_instance == null){lock(lockHelper){if(_instance == null)_instance = new GooglePlay_IAPBridge();}}return _instance;}public void Init(string goName,string publicKey){Debug.Log ("[GooglePlay_IAPBridge]Init：" + goName + "=====" + publicKey);if (Application.platform != RuntimePlatform.Android)return;javaObject.Call ("Init", goName, publicKey);}public bool IsIAPSupported(){if (Application.platform != RuntimePlatform.Android)return false;return javaObject.Call<bool> ("IsIAPSupported");}public void RequestProducts(string jsonData){Debug.Log ("[GooglePlay_IAPBridge]RequstProduct：" + jsonData);if (Application.platform != RuntimePlatform.Android)return;javaObject.Call ("RequstProduct", jsonData);}public void BuyProduct(string productId,bool isConsumable){BuyProductData buyProductData=new BuyProductData();buyProductData.productId = productId;buyProductData.isConsumable = isConsumable;string jsonData = JsonConvert.SerializeObject(buyProductData);Debug.Log ("[GooglePlay_IAPBridge]BuyProduct：" + jsonData);if (Application.platform != RuntimePlatform.Android)return;javaObject.Call ("BuyProduct", jsonData);} } #endif - 再封装一个IAPBridge类，用来分流不同渠道，转接不同接口文件
using UnityEngine; using System.Collections.Generic; using Newtonsoft.Json;public class IAPBridge{class RequestSkuData{public string[] productIds;}public static void InitIAp(string goName,string publicKey=""){Debug.Log("[IAPBridge]InitIAp:" + goName + "==" + publicKey); #if UNITY_IPHONEif(Application.platform==RuntimePlatform.IPhonePlayer){iOS_IAPBridge.InitIAPManager(goName);} #elif UNITY_ANDROIDif(Application.platform==RuntimePlatform.Android){GooglePlay_IAPBridge.getInstance().Init(goName,publicKey);} #endif}public static bool IAPEnabeld(){ #if UNITY_IPHONEif(Application.platform==RuntimePlatform.IPhonePlayer){return iOS_IAPBridge.IsProductAvailable();} #elif UNITY_ANDROIDif(Application.platform==RuntimePlatform.Android){return GooglePlay_IAPBridge.getInstance().IsIAPSupported();} #endifreturn false;}public static void RequstProducts(List<string> productIds){RequestSkuData data=new RequestSkuData();data.productIds = productIds.ToArray();string jsonData = JsonConvert.SerializeObject(data);Debug.Log("[IAPBridge]RequstProducts:"+jsonData); #if UNITY_IPHONEiOS_IAPBridge.RequstProductInfo(jsonData); #elif UNITY_ANDROIDif (Application.platform == RuntimePlatform.Android){GooglePlay_IAPBridge.getInstance().RequestProducts(jsonData);} #endif}public static void SendBuyProduct(string productId,bool isConsumable){Debug.Log(string.Format("[IAPBridge]SendBuyProduct:{0} isConsumable:{1}",productId,isConsumable)); #if UNITY_IPHONEif(Application.platform==RuntimePlatform.IPhonePlayer){iOS_IAPBridge.BuyProduct(productId);} #elif UNITY_ANDROIDif (Application.platform == RuntimePlatform.Android){GooglePlay_IAPBridge.getInstance().BuyProduct(productId, isConsumable);} #endif}public static void RestoreProduct(){Debug.Log("[IAPBridge]Restore!"); #if UNITY_IPHONEif(Application.platform==RuntimePlatform.IPhonePlayer){iOS_IAPBridge.Restore();} #endif} } - 然后Unity这边要接收下Android那边传过来的接口，将这个类挂载到某个GameObject下，如GameObject名为IAPObject，则上面初始化时调用IAPBridge.InitIAP将该gameObject名作为goName参数传过去即可。
