注：现有日志在应用启动阶段截断，未覆盖登录操作执行后的时段。

初步日志分析 #

• 所有React Native相关原生so库均加载成功，无库缺失、加载失败类致命错误
• 单条Salesforce Marketing Cloud SDK线程锁等待110ms属于常规性能波动，不会直接中断登录流程
• 日志中无崩溃、权限拒绝、网络请求失败类错误记录，无法直接从现有日志定位根因

定向排查方向 #

• 优先补全点击登录按钮到错误弹出全时段的完整日志，重点筛选E/、Fatal/级别的错误输出，同时抓取应用接口请求日志确认登录链路的网络调用是否正常
• 排查云设备环境与实体机的差异点，这类仅在云真机出现的问题大概率为环境差异导致：
  • 网络环境差异：BrowserStack默认网络可能存在证书校验限制、域名拦截，确认登录接口、三方登录鉴权接口（如社交账号登录、一键登录服务）在云设备网络下可正常访问，必要时配置和实体机一致的代理规则
  • 设备风控拦截：BrowserStack云设备存在虚拟设备特征、调试环境标记，若应用集成了反作弊、环境检测SDK，会直接拦截云设备的登录请求，实体机无相关风险标记所以可正常登录
  • 架构兼容问题：当前日志显示加载的是arm64-v8a架构库，确认BrowserStack选择的测试设备为arm64架构，避免x86架构转译运行时出现兼容异常
  • WebView版本差异：若登录流程内嵌H5页面，云设备预装的系统WebView版本可能和测试实体机版本不一致，导致H5侧JS执行报错中断登录
