+# 合并记录: dev_rustore 测试内容 → dev_flexion
+
+**日期:** 2026-04-30
+**源分支:** dev_rustore (c105818)
+**目标分支:** dev_flexion (66aa7a9)
+
+---
+
+## 已合并的文件
+
+### 1. sdk-intergration/Assets/Scripts/SDKTest.cs
+
+新增 VK 登录/绑定/检查 和 Review 测试按钮及事件处理:
+
+**新增字段:**
+- `_loginVkBtn` — VK 登录按钮
+- `_linkVkBtn` — VK 绑定按钮
+- `_checkVkBtn` — VK 检查绑定按钮
+- `_reviewBtn` — 应用评价按钮
+
+**新增监听 (Start):**
+```csharp
+_loginVkBtn.onClick.AddListener(() => OnLogin(EAccoutType.hwVkid));
+_linkVkBtn.onClick.AddListener(OnLinkVkId);
+_checkVkBtn.onClick.AddListener(OnCheckVKId);
+_reviewBtn.onClick.AddListener(OnReview);
+```
+
+**新增方法:**
+```csharp
+private async void OnLinkVkId()    // VK 绑定 → TYSdkFacade.Instance.LinkAccount(EAccoutType.hwVkid)
+private async void OnCheckVKId()   // VK 检查 → TYSdkFacade.Instance.LinkCheck(EAccoutType.hwVkid)
+private void OnReview()            // 评价 → UnityBridgeFunc.Review()
+```
+
+### 2. sdk-intergration/Assets/Scenes/SampleScene.unity
+
+直接从 dev_rustore 检出完整文件,包含新增 UI 按钮 GameObject:
+- VK Login 按钮
+- VK Link 按钮
+- VK Check 按钮
+- Review 按钮
+
+### 3. sdk-intergration/ProjectSettings/ProjectSettings.asset
+
+修复构建错误,将 `AndroidMinSdkVersion` 从 25 提升到 26:
+- **原因:** `tuyoosdk_1.0.0.aar` 声明 minSdkVersion 26,低于此版本会 manifest 合并失败
+- **影响:** 全局生效,所有渠道统一 minSdk 26
+
+---
+
+## 跳过的文件 (dev_flexion 已有更完善的实现)
+
+### TYSdkModel.cs — 跳过
+- dev_rustore: 硬编码 `AccountInfo.hwPayType = "rustore.global.app"`, SKUDetail 写死 Rustore 格式
+- dev_flexion: 使用 `ChannelConfig.Channel` 动态区分渠道,同时兼容 Google/Rustore/Flexion
+- **理由:** dev_flexion 的 `ChannelConfig` 抽象更成熟,无需降级
+
+### TYSdkFacade.cs — 跳过
+- dev_rustore: 硬编码 `Channel = "hwVkid"`, 超时 120s
+- dev_flexion: 已有 `Channel => ChannelConfig.Channel`, 动态 `LoginTimeoutSeconds`
+- **理由:** dev_flexion 已包含 VK 映射 `{"vk.global.app", EAccoutType.hwVkid}`, 且抽象更优
+
+### TYSdkFacade_Pay.cs — 跳过
+- dev_rustore: `var pType = tysdk.AccountInfo.hwPayType` (硬编码 rustore)
+- dev_flexion: `var pType = ChannelConfig.PayType` (动态配置)
+- **理由:** dev_flexion 的方案已覆盖 rustore 支付类型
+
+### UnityBridgeFunc.cs — 跳过
+- dev_rustore: 仅代码格式重排,无功能变更
+- dev_flexion: 已包含 `Review()` 等方法声明
+
+---
+
+## 构建错误修复
+
+```
+Error: uses-sdk:minSdkVersion 25 cannot be smaller than version 26
+       declared in library [:tuyoosdk_1.0.0:]
+```
+
+**修复:** `ProjectSettings.asset` → `AndroidMinSdkVersion: 25` → `26`
+
+**替代方案分析:**
+- `tools:overrideLibrary="com.tuyoo.gamesdk"` (rustore AndroidManifest 已有) 只能绕过 manifest 合并冲突
+- 无法绕过 gradle 层 `processReleaseMainManifest` task 的 minSdkVersion 检查
+- 改 ProjectSettings 是唯一可行方案
+
+---
+
+## SKU 列表格式统一
+
+**问题:** Rustore 和 GooglePlay 返回的商品列表 JSON 字段不同，C# 端用同一个 `SKUDetail` 类反序列化。
+
+**方案:** 在 Java 端 `ChannelHelpers.normalizeSkuList()` 中统一格式，C# 端不做渠道判断。
+
+### 数据流
+
+```
+SDK API → defaultThirdExtend() → ChannelHelpers.normalizeSkuList(msg) → Unity SKUListResult → DeserializeObject<List<SKUDetail>>
+```
+
+### 变更文件
+
+#### 1. ExtraPluginCfgs/Android/rustore/ChannelHelpers.java — 新增 normalizeSkuList
+
+```java
+// 将 Rustore 原始格式转为统一格式:
+// price: "199" (戈比) → "₽1.99"
+// 新增 price_amount_micros: "199" * 10000 = "1990000"
+// 新增 price_currency_code: ← currency 字段
+```
+
+#### 2. ExtraPluginCfgs/Android/googleplay/ChannelHelpers.java — 新增 normalizeSkuList
+
+```java
+// GooglePlay 格式已是标准，直接原样返回
+public static String normalizeSkuList(String msg) { return msg; }
+```
+
+#### 3. ExtraPluginCfgs/Android/flexion/ChannelHelpers.java — 新增 normalizeSkuList
+
+```java
+// Flexion 有自己的 SDKHelper.queryProducts()，不走 defaultThirdExtend，编译需要方法存在
+public static String normalizeSkuList(String msg) { return msg; }
+```
+
+#### 4. SDKManager.java — defaultThirdExtend 调用 normalizeSkuList
+
+```java
+// 回调成功时: result.put("respObj", ChannelHelpers.normalizeSkuList(msg));
+```
+
+#### 5. TYSdkModel.cs — SKUDetail 简化
+
+```csharp
+// 去掉 Normalize() 方法和 normalized 字段
+// 属性直接用统一字段:
+// ProdPrice     => float.Parse(price_amount_micros) / 1000000
+// ProdPriceStr  => price
+```
+
+#### 6. TYSdkFacade_Pay.cs — SKUListResult 去掉 Normalize 调用
+
+```csharp
+// 反序列化后直接赋值，不再调 sku.Normalize()
+```
+
+### 扩展新渠道
+
+添加新渠道时只需:
+1. 创建 `ExtraPluginCfgs/Android/{channel}/ChannelHelpers.java`
+2. 实现 `normalizeSkuList()` 将该渠道 SKU JSON 转为统一格式
+3. C# 端无需改动
