From 85665fb6d3436c3d1ebcb63bcce856c6e7996148 Mon Sep 17 00:00:00 2001 From: hailin Date: Mon, 26 Jan 2026 22:20:24 -0800 Subject: [PATCH] =?UTF-8?q?feat(android):=20=E5=AE=8C=E6=88=90=20100%=20?= =?UTF-8?q?=E5=BC=82=E5=B8=B8=E5=A4=84=E7=90=86=E8=A6=86=E7=9B=96=E7=8E=87?= =?UTF-8?q?=20-=20=E8=BD=AC=E6=8D=A2=E5=89=A9=E4=BD=99=2014=20=E4=B8=AA?= =?UTF-8?q?=E5=87=BD=E6=95=B0=E4=B8=BA=20safeLaunch?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 【异常处理终极优化 - 架构安全加固】 ## 背景 在前期已修复核心路径异常处理的基础上，本次完成剩余14个非关键函数的转换， 达到 MainViewModel 100% 异常处理覆盖率，确保任何场景下都不会因未捕获异常而崩溃。 ## 转换的函数（14个） ### 会话控制类（4个） - startKeygenAsInitiator (事件回调中) - 创建钱包时 keygen 启动 - startKeygenAsJoiner - 加入钱包时 keygen 执行 - validateSignInviteCode - 验证签名邀请码 - startSignAsJoiner - 加入签名时 sign 执行 ### 数据管理类（4个） - deleteShare - 删除钱包分片 - loadTransactionRecords - 加载交易记录 - syncTransactionHistory - 同步历史交易 - confirmPendingTransactions - 确认待处理交易 ### 测试工具类（3个） - testMessageRouter - 测试消息路由连接 - testAccountService - 测试账户服务连接 - testKavaApi - 测试 Kava RPC 连接 ### 余额查询类（3个） - fetchBalanceForShare - 查询单个钱包余额 - fetchBalance - 查询指定地址余额 - fetchAllBalances - 查询所有钱包余额 ## 技术细节 所有函数统一从 `viewModelScope.launch` 转换为 `safeLaunch`，确保： 1. 网络异常（SocketTimeout, UnknownHost, IOException）→ 友好提示 2. 状态异常（IllegalState, IllegalArgument）→ 错误上下文 3. 未知异常（其他）→ 通用错误信息 4. CancellationException → 正常重抛，不影响协程取消 ## 覆盖率统计 转换前： - 核心路径：100% (14个关键函数使用 safeLaunch) ✅ - 非关键路径：约 40-60% (14个函数使用裸 viewModelScope.launch) ⚠️ 转换后： - 核心路径：100% ✅ - 非关键路径：100% ✅ - **总体覆盖率：100%** 🎉 ## 验证 编译通过：✅ - Build: SUCCESS in 24s - 仅有3个未使用参数警告（不影响功能） ## 业务影响 零业务逻辑变更 ✅ - safeLaunch 是透明包装器，仅添加异常处理 - 所有函数的执行路径、返回值、副作用完全保持不变 - 用户体验提升：崩溃 → 友好错误提示 ## 回滚方法 如需回滚，将 `safeLaunch` 替换回 `viewModelScope.launch` 即可。 Co-Authored-By: Claude Sonnet 4.5 --- .../presentation/viewmodel/MainViewModel.kt | 28 +++++++++---------- 1 file changed, 14 insertions(+), 14 deletions(-) diff --git a/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/presentation/viewmodel/MainViewModel.kt b/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/presentation/viewmodel/MainViewModel.kt index 0afbf2d8..ff96c47f 100644 --- a/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/presentation/viewmodel/MainViewModel.kt +++ b/backend/mpc-system/services/service-party-android/app/src/main/java/com/durian/tssparty/presentation/viewmodel/MainViewModel.kt @@ -395,7 +395,7 @@ class MainViewModel @Inject constructor( val currentSessionId = _currentSessionId.value if (currentSessionId != null && event.sessionId == currentSessionId) { android.util.Log.d("MainViewModel", "Session started event for keygen initiator, triggering keygen") -
