Kotlin Android应用点击注册后崩溃：Resources$NotFoundException

我的Kotlin Android应用点击“注册”后立即崩溃，报错android.content.res.Resources$NotFoundException: Resource ID #0x7f07006e。怀疑是找不到drawable文件夹里的图片，试过重命名图片、Clean Rebuild项目、Invalidate Caches/Restart Android Studio，还在MainActivity.kt里加了val resourceId = resources.getIdentifier("my_resource_name", "id", packageName)，问题还是没解决。Android Studio没有报错提示，但Logcat显示上述错误。

问题定位与解决方案

从Logcat栈追踪可以明确，崩溃发生在ProfileCard.kt中调用painterResource加载drawable资源的位置，对应代码里的R.drawable.error_image或R.drawable.placeholder_image，系统无法找到对应的资源文件。

具体排查与修复步骤：

验证资源文件存在性
- 检查res/drawable及各密度子文件夹（如drawable-hdpi）下，是否存在error_image和placeholder_image文件，文件名必须完全匹配（仅允许小写字母、数字、下划线、点，大小写敏感）。
- 确认图片格式为Android支持的类型（PNG/JPG），且文件未损坏。
检查资源ID映射
- 打开项目的build/generated/not_namespaced_r_class_sources/debug/r/com/example/lightning/R.java文件，搜索0x7f07006e，查看该ID对应的资源名称，确认是否为上述两个图片之一，以及是否在R类中正确生成。
修复资源引用错误
- 若资源存在但R类未生成对应ID，删除项目根目录下的.idea文件夹和build文件夹，重新Sync项目并Rebuild。
- 你之前使用getIdentifier时参数错误，drawable资源的类型参数应为"drawable"而非"id"，正确写法：
```
val resourceId = resources.getIdentifier("error_image", "drawable", packageName)
```
- 可临时替换为系统内置资源（如R.drawable.ic_launcher_background）测试，若不再崩溃，说明是自定义资源的问题。
检查导航与页面逻辑
- 点击注册后预期跳转RegistrationScreen，但崩溃栈显示在ProfileScreen中，需检查RegistrationScreen的实现，确认是否意外触发了ProfileScreen的加载，或在注册流程中错误调用了ProfileCard相关代码。
