华为设备上CameraX无法生成JPEG文件问题求助

• 两台同型号华为设备出现异常，此前3个月应用运行稳定，多设备已成功处理数千张图片
• 异常触发流程：图片处理服务无法找到CameraX应生成的文件，抛出java.io.FileNotFoundException，后续因尝试访问空Bitmap的getWidth()方法引发致命空指针崩溃
• 当前状态：应用重装后恢复正常，但无法复现异常，且无设备日志权限，需定位问题根源

• 文件命名与路径兼容性：目标文件名包含空格和特殊格式，需检查CameraX的文件生成逻辑是否在华为设备上存在命名兼容性问题，比如系统对带空格的文件路径解析异常
• CameraX文件写入完整性：CameraX完成拍照请求后，可能因华为设备的存储权限临时变更、系统自动清理机制（如后台清理应用文件）导致文件未成功写入或被删除，需验证存储权限的动态申请逻辑，以及是否有后台进程影响文件留存
• 时间戳逻辑错误：拍照触发时间为11-09，但尝试加载的文件时间戳为11-07，需排查是否存在缓存文件未及时清理、服务错误加载历史文件的逻辑问题
• 华为系统特性限制：华为设备的HwViewRootImpl、存储管理机制可能存在特殊处理，比如应用后台运行时的文件访问限制，需检查应用在后台状态下的文件访问权限是否被系统拦截
• 异常处理缺失：FileNotFoundException未被捕获，导致后续操作触发空指针崩溃，需先完善异常捕获逻辑，在文件操作前增加存在性校验，同时记录文件生成路径、写入结果等上下文信息，便于后续复现排查
