但所有依赖项都是正确的。

我还注意到没有 androidApplication() 参数的模块可以正常工作。

代码如下:

    startKoin(listOf(
            imageManagerModule,
            databaseRepositoryModule
    ))

ImageManager 完美运行

val imageManagerModule: Module = applicationContext {
    bean { ImageManagerImpl() as ImageManager }
}

但是首选项崩溃了

val preferencesModule: Module = applicationContext {
    bean { PreferencesImpl(androidApplication()) as Preferences }
}

解决方案很简单，但不是那么明显。

Android Studio 以某种方式导入了独立的 startKoin 函数而不是特定的 android 函数。

所以我不得不更换

import org.koin.standalone.StandAloneContext.startKoin

到

import org.koin.android.ext.android.startKoin

那行得通!
