android - 在 git 中更改分支后，Jetpack Compose Preview 无法使用资源
问题描述
我对 compose 的预览有一个奇怪的问题。最近我在我的项目中添加了 compose。除非我切换到没有 compose 的旧分支，否则一切正常。改回 compose 分支后，预览停止工作。重新启动/无效/重建没有帮助。该代码在模拟器上运行良好。我正在使用带有 Compose 1.0.0 的 Android Studio Arctic Fox Stable 以下是依赖项：
implementation "androidx.hilt:hilt-navigation-compose:1.0.0-alpha03"
implementation "androidx.compose.ui:ui:$compose_version"
implementation "androidx.compose.material:material:$compose_version"
implementation "androidx.compose.ui:ui-tooling-preview:$compose_version"
implementation "androidx.compose.runtime:runtime-livedata:$compose_version"
debugImplementation "androidx.compose.ui:ui-tooling:$compose_version"
androidTestImplementation "androidx.compose.ui:ui-test-junit4:$compose_version"
implementation 'androidx.activity:activity-compose:1.3.0'
implementation "androidx.lifecycle:lifecycle-viewmodel-compose:1.0.0-alpha07"
例如以下代码存在渲染问题：
@Preview
@Composable
fun PreviewMyScreen(){
Image(painter = painterResource(id = R.drawable.ic_android_24dp), contentDescription = null)
}

更新 用不同的模型更改了几次预览后，突然一切都开始工作了。看起来缓存有一些错误
解决方案
import com.package.R
当然，用实际名称替换“项目”。
