Unity接入GooglePlay内购V4(源生Android方式)

發布時間：2023/12/14 Android 71 豆豆

生活随笔收集整理的這篇文章主要介紹了 Unity接入GooglePlay内购V4(源生Android方式) 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

Unity接GooglePlay In-App Billing坑還是蠻多的，各種坑。

接的方式目前來看有三種：

采用Unity IAP插件，開啟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項目，使用Unity調用

打包出Android工程，在Android工程中接入

這次介紹的是第二種，使用安卓源生方式接入，因為該方式一勞永逸，新項目可以很快就完成接入。

為什么不用第一種呢？直接導入IAP插件，然后設置參數，就可以很快實現了，該方式可以直接參考google文檔。

第一種IAP插件的缺點：

雖然該方式只需要導入插件，然后進行一些參數的設置，但是此方式特別麻煩的一點是需要在Unity中開啟Service，但是開啟后又得填一大堆信息，巨麻煩無比，而且Unity的網絡簡直不能看，要么是打不開，要么是卡半死，而且網站老變，以及沒有完整的文檔。這些都是很惡心人的事情，甚至還要創建組織啥的，反正誰用誰惡心。

正式接入

接入之前需要的儲備知識是：Unity如何與Android交互

準備jar和aar

我們的目標是導出自己封裝的jar（里面封裝了接口供Unity調用，也就是橋接層），以及找到谷歌官方提供的Billing V4插件(aar)。

因為從2021.8.2起，谷歌要求必須接入V3版以上的插件。所以我們這次干脆接了最新的V4.

接入文檔可以參考指南：從 AIDL 遷移到 Google Play 結算庫的遷移指南

獲取aar文件

打開Android Studio，創建一個工程
創建一個Module，創建完如下（Module要選擇Library）
打開build.gradle，修改導出為Library，在dependencies中添加依賴，并同步。 implementation("com.android.billingclient:billing:4.0.0") 注意：plugins這邊要改為'com.android.library'，導出才會是aar，否則是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緩存路徑下找到谷歌官方提供的.aar文件，復制到Unity工程Assets/Plugins/Android目錄下，待用
文件路徑：C:\Users\xxx\.gradle\caches\modules-2\files-2.1\com.android.billingclient\billing\4.0.0\31aa58e2d4286f6b96480764e7a84d5de9935f02

打包jar?

創建BaseMainActivity.java類，該類創建了一些供Unity調用的接口格式。
當前類還未開始接入GP插件接口。 package com.egogame;import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.ArrayList; import org.json.JSONArray; import org.json.JSONException;

創建MainActivity類，開始接入billing插件（該命名為Activity其實沒有繼承Activity，因為繼承Activity后，需要Unity那邊AndroidManfiest文件指定為Activity才能生效，所以這里不采用繼承Activity） package com.egogame;import android.os.Bundle; import android.os.Handler; import android.os.Looper; import android.text.TextUtils;import androidx.annotation.NonNull; import androidx.annotation.Nullable;import com.android.billingclient.api.BillingClient; import com.android.billingclient.api.BillingClientStateListener; import com.android.billingclient.api.BillingFlowParams; import com.android.billingclient.api.BillingResult; import com.android.billingclient.api.ConsumeParams; import com.android.billingclient.api.Purchase; import com.android.billingclient.api.PurchasesUpdatedListener; import com.android.billingclient.api.SkuDetails; import com.android.billingclient.api.SkuDetailsParams; import com.android.billingclient.api.SkuDetailsResponseListener;import java.util.ArrayList; import java.util.Arrays; import java.util.HashMap; import java.util.List; import java.util.Map;public class MainActivity extends BaseMainActivity implements PurchasesUpdatedListener,BillingClientStateListener {private static final long RECONNECT_TIMER_START_MILLISECONDS = 1L * 1000L;private static final long RECONNECT_TIMER_MAX_TIME_MILLISECONDS = 1000L * 60L * 15L; // 15 minsprivate static final Handler handler = new Handler(Looper.getMainLooper());private BillingClient billingClient;private String[] cacheRequestList;private Map<String, SkuDetails> skuDetailsLiveDataMap=new HashMap<>();private boolean isConsumable;private String buyProductId;private boolean billingSetupComplete = false;// how long before the data source tries to reconnect to Google playprivate long reconnectMilliseconds = RECONNECT_TIMER_START_MILLISECONDS;@Overrideprotected void OnInitHandle(String googlePlayPublicKey) {super.OnInitHandle(googlePlayPublicKey);if (googlePlayPublicKey.contains("CONSTRUCT_YOUR")) {throw new RuntimeException("Please put your app's public key in MainActivity.java.

選擇Module，并且點擊Build Module，將會導出aar文件
我們將aar改為rar格式，然后用壓縮軟件打開，取出里面的classes.jar，我們只需要該jar即可，該jar是我們封裝好的接口，后續有用，為了方便認，我將名字改為IAPForGooglePlay.jar
將jar放置到Unity工程下，Assets/Plugins/Android目錄下，該目錄下文件如下：
注意：jar要放在Android目錄下，而不是Android/libs目錄下，經試驗放libs下會識別不到
Android這邊的工作就結束了，后面我們來寫Unity這邊的代碼

?編寫Unity接口

創建類GooglePlay_IAPBridge，編寫調用Android我們封裝好的jar里的接口的橋接類 #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 這里面我們直接 javaObject = new AndroidJavaObject("com.egogame.MainActivity");實例化我們jar封裝好的類，即可直接調用public方法。請注意：因為Android和Unity線程不一樣，所以jar處理時需要規避線程的同步性。
再封裝一個IAPBridge類，用來分流不同渠道，轉接不同接口文件 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這邊要接收下Android那邊傳過來的接口 using Newtonsoft.Json; using UnityEngine; #pragma warning disable 0649/// <summary> /// 該類主要用于接收iOS和Android回調，做一個橋接用途 /// </summary> public class IAPMessage : MonoBehaviour {class BuyFailData{public string productId;public string error;}#region callback from Objective-c/JAR//獲取到產品列表回調void RecieveProductInfos(string jsonData){if(string.IsNullOrEmpty(jsonData)) return;var infoData = JsonConvert.DeserializeObject<IAPProductInfoData>(jsonData);OnProductInfoReceived (infoData);}//產品列表請求失敗void ProductRequestFail(string message){OnProductInfoFail(message);}//購買成功回調void ProductBuyComplete(string productId){OnProductBuyComplete(productId);}//購買失敗回調void ProductBuyFailed(string jsonData){var infoData = JsonConvert.DeserializeObject<BuyFailData>(jsonData);OnBuyProductFail (infoData.productId, infoData.error);}//獲取商品回執回調void ProvideContent(string msg){}//購買取消回調void ProductBuyCancled(string productId){OnBuyProductCancled(productId);}/// <summary>/// 恢復購買成功/// </summary>/// <param name="productId"></param>void RestoreComplete(string productId){OnRestoreCompleted (productId);}#endregion//接收到產品信息void OnProductInfoReceived(IAPProductInfoData info){Debug.Log("[IAPMessage]Unity接收到商品信息:" + info.ToString());IAPManager.internal_CallBySDK_ProductInfosReceive(info);}//接收到產品信息void OnProductInfoFail(string error){Debug.Log("[IAPMessage]Unity商品信息請求失敗:" + error);IAPManager.internal_RequestProductInfoFail(error);}//購買完成void OnProductBuyComplete(string productId){Debug.Log ("[IAPMessage]購買完成" + productId);IAPManager.internal_CallBySDK_BuyComplete(productId);}//購買失敗void OnBuyProductFail(string productId,string error){Debug.Log(string.Format("[IAPMessage]購買失敗:{0} 錯誤信息{1}", productId, error));IAPManager.internal_CallBySDK_BuyFail(productId, error);}//購買取消void OnBuyProductCancled(string productId){Debug.Log ("[IAPMessage]購買取消" + productId);IAPManager.internal_CallBySDK_BuyCanceled(productId);}//恢復完成void OnRestoreCompleted(string productId){Debug.Log ("[IAPMessage]恢復購買完成:"+productId);IAPManager.internal_CallBySDK_RestoreCompleted(productId);} }#pragma warning restore 0649
using System.Collections.Generic;public class IAPProductInfoData {public List<IAPSkuItem> skuItems;//請求到的產品列表public string[] invalidIds;//無效產品id }public struct IAPSkuItem{public string productId;//后臺產品idpublic string title;//后臺標題public string desc;//后臺描述public string price;//格式化價格，顯示請用formatPrircepublic string formatPrice;//格式化價格，包括其貨幣符號public string priceCurrencyCode;//貨幣代碼public string skuType;//內購還是訂閱 subscription/inapppublic override string ToString (){return string.Format("[productId]:{0} [title]:{1} [desc]:{2} [price]:{3} [formatPrice]:{4} [priceCurrencyCode]:{5} [skuType:]{6}",productId, title, desc, price, formatPrice, priceCurrencyCode, skuType);} }public struct IAPProvideData {public string cfgId;public string title;public string desc;public string formatPrice; }
到這里就接入完成了，調用對應接口即可實現IAP的接入。
