但是所有依赖项都是正确的.

But all dependencies were correct.

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

Also I noticed that modules without androidApplication() argument works correctly.

代码如下:

    startKoin(listOf(
            imageManagerModule,
            databaseRepositoryModule
    ))

ImageManager完美运行

ImageManager works perfectly

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

但是偏好设置崩溃

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

推荐答案

解决方案很简单，但并不那么明显.

Solution is easy but not so obvious.

以某种方式，Android Studio导入了独立的startKoin函数，而不是特定的android函数.

Somehow Android Studio imported standalone startKoin function instead of specific android function.

所以我不得不替换

import org.koin.standalone.StandAloneContext.startKoin

收件人

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

那行得通！
